I'm building DB Pro, a cross-platform database management app that lets you browse, query, and manage SQLite, PostgreSQL, MySQL, Redis, MongoDB, and more from a single native interface. It's been growing steadily with a community of ~1,400 subscribers on YouTube and paying users.
What I'm most excited about right now is DB Pro Studio: a collaborative web-based version I'm building on top of it.
The idea is simple: databases are a team activity, but every DB tool treats them as a single-player experience. Studio adds either a self-hosted or managed hosted data browser, real-time collaboration, dashboards, visual workflow automation, and enterprise features like audit logging and role-based access. Think "database command center" where your whole team can inspect, query, and build on your data together.
The desktop app acts as the execution engine (your data never leaves your infrastructure), while Studio provides the shared dashboard layer.
I've also consistently posted devlogs on YT throughout the journey, which has helped build a community of ~1,400 subscribers who've shaped the product along the way.
I find that when people can see what's coming, they're more invested in the product and more likely to share feedback that actually shapes the direction. The devlogs on YouTube serve the same purpose. It's a two-way street.
Thanks Steve! The team angle came from mine and my co-founder's own frustration. We kept copy-pasting query snippets and results of queries into Slack/Teams to our engineering team but also Sales/Marketing etc. Figured there had to be a better way. If you ever want to give it a spin, I'd love to hear your thoughts.
I'm a solo dev building a handful of apps across different niches..
- Kvile ( https://kvile.app ) ā A lightweight desktop HTTP client built with Rust + Tauri. Native .http file support (JetBrains/VS Code/Kulala compatible), Monaco editor, JS pre/post scripts, SQLite-backed history. Sub-second startup. MIT licensed, no cloud, your requests stay on your machine. Think Postman without the bloat and login walls.
- Mockingjay ( https://apps.apple.com/us/app/mockingjay-secure-recorder/id6... ) ā iOS app that records video and streams AES-256-GCM encrypted chunks to your Google Drive in real-time. By the time someone takes your phone, the footage is already safe in the cloud. Built for journalists, activists, and anyone who needs tamper-proof evidence. Features a duress PIN that wipes local keys while preserving cloud backups, and a fake sleep mode that makes the phone look powered off during recording.
- Stao ( https://stao.app ) ā A simple sit/stand reminder for standing desk users. Runs in the system tray, tracks your streaks, zero setup. Available on macOS, Windows, Linux, iOS, and Android.
- MyVisualRoutine ( https://myvisualroutine.com ) ā This one is personal. I have three kids, two with severe disabilities. Visual schedules (laminated cards, velcro boards) are a lifeline for non-verbal children, but they're a nightmare to manage and they don't leave the house. So I built an app that lets you create a full visual routine in about 20 seconds and take it anywhere. Choice boards, First/Then boards, day plans, 50+ preloaded activities, works fully offline. Free tier is genuinely usable. Available on iOS and Android.
Love this! Had the same idea as Mockingjay for emergency situations where you donāt have time to upload, e.g. robberies, attacks, etcā¦ will give it a try!
Really neat! Also as a Linux user, I deeply appreciate the linux support :-)
A few questions and comments:
| Kvile |
- Awesome, really happy to see a reasonable take on this (open source, offline-first, no telemetry, no acount, etc). Do you think at some point you'll try to monetize it in some way?
Kvile: Thanks for letting me know! havent noticed, since i mostly just use it myself. Will get it fixed!
Stao: Hm yea this is a mistake on my LLM when it generated the website for me (i couldnt be bothered). It probably got confused since i released it for Linux. Its not open-source. Yes! Exactly, thats why i made it, i ALWAYS forgot. I still do, but far less frequently than before, using Stao helped me a lot.
> All apps i found were either shit, real shit, or didnt solve my personal need.
Wow, what an amazing coincidence. I made something that looks pretty similar from the looks of it just a few weeks ago because I found the same thing. If I knew your app existed I probably wouldn't have made it. I wasn't even thinking of selling it, just made it for my kid because it makes following various daily routines easier.
It's a mostly vibe coded (well, I made tons of visual and technical decisions but didn't look at the code much except some spot checks) PWA that can run offline on an iPod Touch.
It has some quirks and hidden features for day schedules, timers, etc.
There's plenty of yank in there (yours is almost certainly built better) but it works pretty well for most daily routines.
I love the idea behind MyVisualRoutine as a father with a disabled kiddo, thanks for sharing.
The app is beautiful - much better than I could build - what tech is it using if you don't mind me asking? Is it flutter, react native, something else? Just want to get better at mobile dev.
Thank you so much! Then you know my pain. All apps i found were either shit, real shit, or didnt solve my personal need. Hopefully this might help others the way it did for our family. The app is built using flutter because im going to release it on Android too very soon, and I couldnt be bothered creating it twice. Initially the idea was more of a game-like-app, and then it made sense to use flutter. Now though, its not really game-like and couldve just as well been native (apart for me not bothering doing it twice). If i wouldve done it again from scratch, for this app, i would still have chosen flutter.
there's a line between functionality that can be abused and that which is very likely; the author is obviously on the former side of this line so you can take your crusade somewhere it could be useful.
I'm not on a crusade. I'm telling you what it's likely to be used for in case you didn't think of it yourself. Pointing out that it's likely to be used for nefarious purposes is not equivalent of making an argument that it shouldn't exist.
I can appreciate that it's useful for journalism while also warning you that not every user is going to be a journalist. It's possible to have a conversation without being in a fight all the time.
I've been working with my wife on Uruky [1] for a couple of months, now. It's a EU-based Kagi [2] alternative (privacy-focused and ad-free search with domain boosting/exclusion rules).
We've been using it with friends and family semi-successfully (hashbangs work for edge cases we're still working on).
It's really difficult to get bigger indexes other than Mojeek and Marginalia to want to work with us and improve the results further, so that's something I've been researching more, lately. EUSP (the new Ecosia/Qwant-effort-related index) has finally replied to me last week, but I'm still waiting on an API key.
If you're interested in trying it for a few days and are a human, reach out with your account number and I'll give you a couple of weeks for free. We're pushing improvements daily.
Thanks! It's intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such), using Deno in the backend and PostgreSQL for the DB.
My friend and I have been working on https://www.vespper.com
its essentially an ai-native word editor for long-form content.
it comes with a suite of tools (multi-agent tools to do search over many docs, RAG out of the box, prompt generation per section to reduce context drift, granular AI steerability, structured block generations for 100+ page reports ect.)
EACL: Enterprise Access ControL is a situated ReBAC Authorization system based on SpiceDB, built in Clojure and backed by Datomic ā https://github.com/theronic/eacl
'Situated' here means that your permission schema & permission data live with your data, which has a number of benefits:
- one less network hop, so can be faster than Spice for typical workloads,
- one less distributed consistency & syncing problem,
- one less component to run in prod with full consistency,
- potential to implement ZedToken / Zookies via Datomix txid, and
- easy to test new schemas with in-memory Datomic.
EACL is plenty fast without a cache since horizontally-scalable Datomic Peers already cache datoms aggressively, but there is another 10-100x improvement in the pipeline. EACL is especially suitable to real-time multiplayer apps built in frameworks like Electric Clojure.
IMHO, EACL is currently the best-in-class authorization library in the Clojure ecosystem and is improving every week. ReBAC subsumes both ABAC & RBAC. I recently applied for Clojurists Together funding to improve cursors for intermediate resource traversal, which is the primary perf. bottleneck.
EACL was not "vibecoded" as all tests were written by me and all code is human-reviewed, but EACL would not be possible for a single engineer to build mainly in his spare time without AI assistance.
I built a TUI sampler which cherry-picks my favourite features from modern & vintage hardware samplers, DAWs, plugins, outboard FX gear, and DJ equipment.
If you know what an AKAI MPC Live, MPC 3000, SP404, SP1200, BOSS RC-202, Alesis 3630, Serato Sample, S950 filters, and stem separation does, then you'll love seeing these "greatest hits" up in a terminal interface.
Last year while on vacation in Costa Rica, I started scratching my own itch for locating and organizing samples, which quickly evolved into adding more and more features while keeping it tactile and immediate. It was too fun to stop so I kept going. After a few days I was happily making beats in it, and since then it's only gotten better.
It's live and totally free to use, and works in macos & Linux (Windows soon). I'm about to launch v1.0 now, just working with folks in the community to round out the Factory Kits a little more for users new to beatmaking.
Turns out, making beats with no mouse and a terminal interface strikes the perfect balance of hardware feel and software power, and I'm loving the result. Been sharing it with folks in my beatmaking sphere and have plans to continue expanding its reach through more collaborations, contests, and in-person events.
Hope it brings you as much joy as it does to me :)
totally fair point! the medium/long-term roadmap is to layer in a BBS-esque community, so identity is required. more on this later! regardless, might be nice to have an unauthenticated / "Skip sign in" flow for the folks who just want to use the tool.
Iām working on an app builder that combines a Figma-like canvas for design with Apple Shortcuts-style logic for functionality.
Instead of writing code or connecting node graphs, you define behavior by stacking instructions using a syntax based on Hyperscript.
A podcast on the history of the āMajority Worldā - that is Africa, Asia, the Middle East, Oceania, Latin America and the indigenous people around the world - from a decolonisation point of view.
I just published the first episodes today and have zero listeners or subscribers, so it can only grow from here!
Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics: https://circuitscript.net/. A basic IDE (called the Bench) to try Circuitscript is available online: https://bench.circuitscript.net/
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) for work in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!
How effective at circuit generation are LLM's with the language? I tried similar, and could get syntactically correct files, but the content always had errors:

Laboratory.love lets you fund independent plastic chemical lab testing of the specific foods you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kidās snacks, or whatever youāre curious about.
Find a product (or suggest one), contribute to its testing fund, and get full lab results when testing completes. If a product doesnāt reach its goal within 365 days, youāre automatically refunded. All results are published publicly.
This project was inspired by Nat Friedman's PlasticList.org and we use the same ISO 17025-accredited methodology they did, testing three separate production lots per product (when possible) and detecting down to parts-per-billion. The entire protocol is open.
I just published new results today! Turns out Muir Glen's caned Fire Roasted Diced Tomatoes are incredibly low in plastic chemicals. Yay!
It's a lightweight screen recorder for macOS that lives in your menu bar. It's built with SwiftUI and ScreenCaptureKit, uses the native Content Picker to select what you record, and supports ProRes 422/4444, HEVC, and H.264 ā including alpha channel and HDR. Frame rates from 24 to 120fps. System audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.
No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac.
I thought it would be pretty simple, but here I am almost 6 months later still adding features. The positive feedback has been nice, though! People seem to appreciate (like I do) that its fast and doesn't use Electron or some other cross platform toolkit. Learning a lot.
It's not vibe coded. Sad that I have to make that qualification these days, but here we are.
I've always noodled about this marketplace idea where an optimization algorithm could match your interests and a dollar amount you can afford to let you rent/buy artist's music. The optimization would maximize the purchase of the differently valued music(analogus to the weighted knapsack problem but this could have multiple solutions, knapsack is a nice way of thinking about it logically, in reality implementation may be completely different) based only on your interests, like history and dollars u have. I am wondering how might one apply a distributed systems approach without having music pirated and shotgunned all across the internet? Like how would you quickly match a person to all the available music metadata? How would you model for interest matching if the music library is spread out across multiple nodes.
I would imagine a lot of people are ok with paying 5-10$ a month instead of 15-20$ for music they like from a set of artists they like.
I think you can still make the distinction of vibe coded vs using LLM for specific things(like review your code and write tests).
Vibe coding signifies a lack of control over one's own code and generally only if it's to generate ideas or throwaway. The negative connotation that goes with it is appropriate too.
In reality any project that takes 6 months means your have invested a lot of time thinking about the code, in which case LLMs become more useful for the things you care about e.g. maintainability, forcing LLMs to bend to your will, which is like saying: " I know this design is the best so just make this instead of whatever abstraction you think is better".
Definitely more common to just use streaming services like Spotify, but some people do own their music library. Thereās probably a decent sized overlap of those who buy music and those who self host things like jellyfin
Pretty much. I plan on using this program for a long time. I donāt want a codebase that looks like something out of a H.P. Lovecraft novel when I have to fix something in the future.
Here's an analysis of your codebase by Claude Opus 4.6 and Kimi 2.5 -- I don't code in Rust or GTK so I can't vouch for how spot on this is but I hope it's not too far off the mark and helps you improve your code. (Claude is wrapping both analyses together.)
Strong agreement
- Panicking error handling ā both flag unwrap()/expect() on fallible operations (secrets, HTTP client, GStreamer). Kimi specifically calls out get_stream_uri returning String instead of Result, which I missed ā good
catch.
- Excessive cloning ā both note the Jellyfin client and string cloning. Kimi's phrasing ("host.to_string() on every request construction") is more specific than mine.
- Application struct overloaded ā both agree it holds too many responsibilities. Kimi suggests splitting into LibraryService, PlaybackService, etc. I focused more on the RefCell exposure.
- Silent error suppression ā both flag let _ = sender.send(...) and unwrap_or_default() patterns.
- Code duplication in UI ā both identify the repetitive list/detail/sorter patterns. Kimi specifically calls out call_on_visible_page widget comparisons, which I grouped under the broader "5+ copies of factory setup"
observation.
- Missing HTTP timeouts ā Kimi flags this explicitly. I noted it indirectly via the buffer_unordered without timeout, but Kimi is clearer.
Things Kimi caught that I didn't emphasise
- get_stream_uri returning String instead of Result ā a genuine API design issue I glossed over.
- String-based signal names being error-prone with no compile-time checking ā fair point, though it's idiomatic GTK4/Rust.
- glycin potentially unused ā I didn't check dependency usage.
- Position polling not accounting for seeks ā a practical UX observation I missed.
- /proc/sys/kernel/hostname read being cached in OnceLock ā Kimi approves the caching but notes it could be done once at startup. Minor but valid.
Things I caught that Kimi missed
- Actual bugs ā queue reorder off-by-one, playlist DnD index error, toast format string "HTTP {} error" never substituted, double-wrapped Result in stream_info.rs, reversed comment in shuffle logic. These are concrete
defects, not just style issues.
- Concurrency issues in depth ā the Cell<bool> shuffle state race, futures::Mutex inside glib::spawn_future_local deadlock risk, queue mutation race between remove_all() and extend_from_slice().
- Signal handler accumulation on widget reuse in ListView factories ā a slow memory leak.
- Main-thread blocking from synchronous library filtering in detail views.
- Image cache with no eviction ā unbounded disk growth.
- bytes_to_texture panicking inside a Result-returning function ā defeats the entire error contract.
Are you serious? You donāt think Iām capable of running the codebase through an LLM? Or is this supposed to be some kind of gotchya? Rude and lame.
Not everyone is paying for LLMs, even now. So I think it is perfectly reasonable to assume good intentions, here.
Someone spent their own tokens to ponder your code and thought they'd share the result. For anyone else looking, like me, I can see that this is probably going to come up relatively clean without having to spend my own tokens, or install it, and I'm more likely to, now that I can see that.
Oh I'm ever so sorry -- because of course "I donāt want a codebase that looks like something out of a H.P. Lovecraft novel when I have to fix something in the future." is not at all rude and lame and you write perfect non-Lovecraftian code all day every day ā¦
Iāve been shipping AI-written code for 2 years now. I can build something amazing in 40 mins but then spend 4+ hours debugging because the agent has no idea how the libraries itās calling actually work. Docs are stale, StackOverflow is dead, training data is outdated. Every engineer I talk to has the same problem.
So I built Instagit, an MCP server that lets your coding agent understand any GitHub repo in depth so it can get it right on the first try. Works with Claude Code, Codex, Cursor, OpenClaw, etc.
No API key or account needed to try it out. Just need to share these instructions with your coding agent to get started:
Interesting! How does it work under the hood? If you can share. Would like to understand if this improves my Claude Code's understanding of my codebase.
Itās basically scanning the source code for each question (you can also check out specific branches or release tags if you need to debug a particular version) and then writes up the answer once it finds it.
Itās not really meant to query your own code base (Claude Code already does a great job at that) but more to explore other code bases you want to integrate with.
hey irrelevant question, what tools you use to make such great landing pages for your products? your instagit.com looks great, what's your vibe coding workflow?
- Use a static website generator (I use Astro but there are others) where the agent can fully control every aspect of the website
- Use skills to enhance the prompting, like this frontend-design one but can also combine it with copy writing/seo skills etc
- Give the agent control access to the browser to give it visibility into the result in order to iteratively improve upon it
- The last thing is to just be very demanding and setting a high bar, so ask for animations and ask the agent over and over again āok and now letās improve what you just didā
Context7 is great but ultimately itās just a pre-generated static summarization that might not include the specific answers the agent needs. I have a slightly different approach where the actual source code is scanned for each question so itās much more targeted and never out of date.
Iām building datenba.ch, a hyper-local ādigital villageā for a few small communities in rural Germany (Neckartal/Odenwald-ish).
Instead of another social network, itās a bundle of small, practical community tools under one umbrella, combining of the shelf-software with purpose-built projects of our own.
Our current areas of focus are
- help! a neighbor-to-neighbor help board (rides, errands, PC help, garden/handwork)
- hubs! for shared spaces / tool-sharing / events / social hubs
Right now Iām building the integration surface (claims, roles, provisioning), polishing onboarding, and trying to design help!/hubs! so theyāre useful even with low activity.
If anyoneās done (hyper-)local community platforms: Iād love to hear what actually drove adoption and what did not work out for you.
It lets you take photos of all the animals you see to collect them, when you 'capture' a new animal, it gives you fun facts about them.
I seeded it with UK zoos, but there's no reason it can't work elsewhere.
It was built because the signage at a zoo we went to was terrible and we had no idea what some animals were, so it matches your photo with the list of animals to the best of its ability.
That's a lovely idea! I wanted to build something similar for safaris but the lack of network in remote areas makes it a bit tricky to use online image recognition models. I never went down the rabbit hole to use offline ones.
I built a CLI tool in rust to find and remove duplicate files.
At work I sometimes download the same file multiple times to my machine and have to go through my downloads folder and manually remove the duplicates, so this is something I built to speed up the process of doing this.
From what I can tell, your program treats files as duplicates if they share the same normalized filename and the exact same size; it doesnāt compare contents or hashes.
Mine samples bytes at specific positions, hashes those samples, and compares the hashes to produce a similarity score rather than a strict match. This works great for photos, two shots taken in the same second can differ slightly in pixels but still depict the same scene, so theyāre considered duplicates. It also normalizes image orientation by rotating based on the brightest corner, so photos in different orientations are compared
using the same features.
https://concludia.org/ - I've mentioned it here before, it's a site to help people reason through and understand arguments together. No real business purpose for it yet, it's more an idea I've had for years and have been wanting to see it through to something actually usable. You can graphically explore arguments, track their logical sufficiency/necessity, and make counterpoints. It's different than other types of argument theory that just have points "in favor" and "against" because of how it tries to propagate logical truth and provability.
Iāve had a concept like this in the back of my mind for years. Happy to see someone executing it so well.
For me, it started when I spent a year and a half reading and digesting books for and against young earth creationism, then eventually for Christianity itself (its historical truth claims). It struck me that the books were just a serialization of some knowledge structure that existed in the authorsā heads, and by reading I was trying to recreate that structure in my own head. And thatās a super inefficient way to go about this business. So there must be a shortcut, some more powerful intermediate representation than just text (text is too general and powerful, and you canāt compute over itā¦ until now with LLMs?)
That graph felt a lot like code to me: thereās no unique representation of knowledge in a graph, but there are some that are much more useful than others; building a well-factored graph takes time and taste; graphs are composable and reusable in a way that feels like it could help you discover layers of abstraction in your arguments.
Yes - currently, each argument/graph is independent, but I've designed it in a way that should be compatible with future plans to "transclude" parts of other public graphs. Like if some lemma is really valuable to your own unrelated argument, being able to include it.
I do think there's quite a lot that could be done with LLM assistance here, like finding "duplicate" candidates; statements with the same semantic meaning, for potential merge. It's really complicated to think through side effects though so I'm going slow. :)
We would have saved so many wasted hours in the last company I worked for if we had this... you have no idea, to give you a sense, the decision to move from a Neo4J db to MySQL (the service was failing, the DB was failing, it was a bad architecture decision) took 6 months, when it should have been at most a couple days discussion.
Nurture this, it will become a great tool in the belt for a lot of people
Do you mind me asking, what kind of problems did you run into with Neo4j? Did you encounter performance issues after the DB grew to a certain size, or did you realize that the data wasn't suited to a graph DB and weird query patterns started causing trouble, or was it something else entirely?
I'm considering using a Neo4j self hosted instance for a project, but having only played around with it in low-stakes + small-data toy projects, I'm not really familiar with the footguns and failure modes...
All that aside, plugging holes in a sinking database for six months because you can't come to a descision does not sound like a fun time :D
This is pretty cool! I'm not sure how you'd make a business out of it, but I can definitely see myself using it to justify some decisions on my day to day stuff.
I'm also a sucker for serif fonts so points for that.
I wanted to add more value to this comment about monetisation - regardless if that's doable or not, it's an extremely cool project!!
What if you could sell the data for each argument? That might be valuable to LLM labs, because then you can essentially guarantee that every single argument you provide is human checked, and you could accumulate a large DB of those. Of course you'll never be able to capture every single argument possible, but it's rather a mechanism that would allow incremental improvement with time. But codifying logic and natural language is a very nice idea.
Yeah, I only just yesterday got it to the point where people can create their own arguments. I was just using it to check my own assumptions on why I have such a complicated "end-of-month finances" list of things to do. :) But I also like the idea of using it for political arguments or even fun stuff like mystery-solving.
I like this. It reminds me of the interesting type of experimentation that was done with LLMs before agentic coding took over as the primary use case.
I am interested in seeing a personal version of this. Help people work out their own brain knots to make decision-making easier. I'm actually decent at mending fences with others. Put making decisions myself? Impossible.
You can actually register now (with a waiting list) and make your own private graphs, if that's what you meant by a personal version. (You'd be like member #4 haha)
I've actually had a lot of fun hooking it up to LLM. I have a private MCP server for it. The tools tell it how to read a concludia argument and validate it. It's what generated all the counterpoints for the "carbon offset" argument (https://concludia.org/step/9b8d443e-9a52-3006-8c2d-472406db7...) .
And yeah... when I've tried to fully justify my own conclusions that I was sure were correct... it's pretty humbling to realize how many assumptions we build into our own beliefs!
Frustration at that kind of debate has been a large part of the motivation, how it occludes so much of what ideally should be a dialectic. I especially dislike how if someone gets flustered, they're seen as losing.
A tool for creating CSS color palettes for web UIs that pass WCAG accessibility standards for color contrast, where you can fine tweak all the tints/shades quickly using a hue/saturation/lightness curve editing interface:
Unlike most tools based around autogenerating colors, this is more of an editor that lets you fully customise all the tint/shades to your liking with a focus on accessibility. This is important when you've got existing brand colors to include and want to find accessible color combinations that work together.
Would love feedback in general and especially from designers/devs who have different needs in how they go about creating branded palettes!
> I've been relying on ChatGPT to select color schemes/palettes for me
Thanks! Any problems you've found with this approach or it's usually good enough?
For me, I couldn't find a tool that would let me customize multiple color scales at once, check they look good together on a mockup, and also be accessible. It's one of those problems where you can autogenerate something that gets you most of the way there, but then for it to be usable you need need to see how it looks on designs and fine tweak it.
So for my tool, I really need the live UI mockup without having to export first to tweak the colors until they work (e.g. often the off-white/very-light colors used for backgrounds are too vibrant otherwise), the control-point based curve editing helps to explore hue/saturation/lightness curves around a brand color without a lot of clicking, and I want the option for palettes where each color scale follows the same steps in lightness (for predictable contrast between steps from different color scales).
Barely any designers I work with know about P3 colors (feels like P3 mostly appeals to developers right now, for programmatic reasons?), so I'm not that interested in P3 if it means using OKLCH with its intimidating looking color picker. My tool uses HSLuv, which looks familiar like an HSL color picker, where unlike HSL only the lightness slider alters the WCAG contrast, so HSLuv (while limited to sRGB) is great for exploring accessible colors.
I've actually got support for APCA, but I find many struggle understanding WCAG contrast requirements already. There's Figma export too.
Anyway, there's lots of overlap between different color tools but the small details are important for different workflows and needs. I've started to realise too that most designers need a lot of introduction into building (accessible) color palettes in general so it's a tricky puzzle between adding features and trying to keep it simple, which is why I'm very open to suggestions!
I love making games, and Iāve been building a no-code game engine by extracting reusable components every time I ship a new game. It started as me scratching my own itch, and now itās turning into a real platform.
Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click.
For game logic, I recently added a visual event system Iām really excited about. Itās kind of like Unreal Blueprints, but focused on 2D. You pick a trigger, wire conditions, and chain actions in a node graph [1].
Big challenge right now: most people who want to make games needs assets, and don't know how to get/make them. So Iām building a marketplace where pixel artists can upload tilesets/characters, and unlike itch.io, assets are usable directly inside the engine. No ZIP downloads or import setup, just browse and drop into your game. A preview here[2].
Also, if you want to use the editor but ship elsewhere, you can export terrain, animations, and hitboxes to Godot 4. Nothing is locked in.
The engine/editor is at https://craftmygame.com if anyone wants to poke around! And you can test a games here[3][4], and 1 multiplayer game I've tested IRL in a bar [4]!
As a web dev you're in a better spot than you think ā state management, event handling, render loops... you already have the mental models.
Claude Code can genuinely help you with:
- Scaffolding a game project (Phaser.js is great for web devs getting into 2D)
- Writing boilerplate: input handling, collision detection, basic physics
- Debugging weird edge cases in game logic
- Generating utility code like sprite sheet parsers, tilemap loaders, etc.
What it can't do (and where most beginners hit a wall):
- Game design. Knowing what makes a game actually fun is a skill Claude can't shortcut. You need to playtest, iterate, and develop taste.
- Art and assets. This is the #1 blocker for most solo devs. Claude can't draw your sprites or design your tilesets.
- Feel and polish. Tweaking jump curves, screen shake timing, hit feedback ā that's all manual iteration. AI will give you "technically correct" values that feel lifeless.
- Architecture decisions. Claude will happily generate an ECS system or a scene manager, but it doesn't know your game's actual needs. Bad architecture early on will cost you weeks later.
Start with a tiny scope (like a single-screen platformer), use Claude Code to move fast on the code side, but spend most of your energy on the parts AI can't help with ā design and feel.
Also, shameless plug, if you want to skip the code entirely and just focus on making the game, that's what CraftMyGame is for. Everything is visual, no coding needed. Might be a good way to prototype ideas fast before deciding if you want to go deeper on the code side ;)
CraftMyGame can make something like retro street fighter(not need to be perfect) ? If it can, and allow me to export the code(I would like to add those game to some of the apps I'm planning), you'll get paying customer.
It was inspired by 2025 by thomaswc, a 45x45 connections-like puzzle. Globs jumped off from there and it's been very fun to make. I have AI generating the puzzle groups and it keeps surprising me everyday with what it comes up with. I've got demos up for over 20 different languages, and many different sizes of puzzle. Just recently, I got the puzzle to be generated daily for American English, British English, High German and European Spanish. It can also do custom theme puzzles like the following:
There is still some bugs I am tracking down (open the page in a private browser if you hit stale data) but the game has really come together lately and been a lot of fun, I hope you all like it!
I built https://measuretocut.com after too many DIY projects ended with another trip to the hardware store. It figures out how much material you actually need and how to cut it to minimize waste or costs. When I released it in December it just handled 1D cuts for things like boards, bars, and pipes. You enter what you need, and it lays everything out visually on stock lengths. This morning I released the 2D sheet cut calculator to do cut plans for plywood and similar sheet materials. Any feedback is welcomed from fellow engineers turned woodworkers!
Look at count.co for a Figma-like approach to databases.
We were using it at work (transitioning to Metabase); it's great for exploring and debugging and prototyping but it ends up too much of a tangled spaghetti mess for anything long-term. Would not recommend for user-/other-company-departments-facing reports or dashboards.
The choice to use Count was made before I joined the company; IIRC they migrated to it from Tableau.
We wanted to migrate (to Streamlit, back then) to have the SQL not live locked in a tool, but inside our git repository; to be able to run tests on the logic etc. But the spaghetti mess was felt too, even if it wasn't the main reason to switch.
(But then, 1) some team changes happened that pushed us towards Metabase, and 2) we found that Streamlit managed by Snowflake is quite costly, compute-time wise. (The compute server that starts when you open a Streamlit report, stays live for tens of minutes, which was unexpected to us.)
----
Export to DBT sounds great. Count has "export to SQL" which walks the graph of the cell dependencies and collects them into a CTE. I can imagine there being a way to export into a ZIP of SQL+YML files, with one SQL file per cell.
Somehow i had landed on your page sometime back and was just impressed with the quality of landing page and also the concept. Hope to use it in near time.
The website is great and the examples (like getting distinct values of a table as a prerequisite investigation) really get the point across.
In my job I always end up with big notebooks of data exploration that get messy fast and are hard to share anything but the final result, having a canvas that embraces the non-linear nature is a great idea.
The basic idea is that you give Emilia knowledge about your family and friends, and then you can ask her questions or (eventually) get reminders.
I was motivated during an extended family gathering where I completely blanked out on the names of the partners of some of my cousins. I felt awful... trying to hide the fact that I didn't remember their names.
Now the names and who they are etc is there in Nonna Emilia, and through natural text I can ask questions like "what's the name of all the partners of my cousins on the side of my dad's family?" or something like that.
I am looking for alpha users. The service has legit helped me a few times already remembering stuff, but the amount of work to input all this data still bothers me.
Anyway, it's free. If you want go ahead and try (bugs here and there I bet, and you need a Google Account) and shoot me an email at inerte@gmail.com if you have any comment.
I am currently building an alethiometer from the phillip pullman book series: his dark materials
Specifically its a remake knowing what we know now having finished the two trilogies.
Instead of the three hands and the moving needle, its just one moving needle. Its made from wood and aluminium. The reason for aluminium is that in the 1920s (roughly the age that these books are set) is a wonder material, a bit like carbon fibre/titanium is now.
I have the working mechanism (controlled by 8mm steppers) I need to finish the case and dial, and paint it. I also need to shrink the controlling mechanism and design the voice->text->inference->output to 36 symbols logic.
I'm an embedded software engineer by day and like it or not I have to acknowledge that AI tooling is coming to our work, so I'm currently working on learning to interact with AI coding tools like Claude Code more effectively and efficiently by "vibe-coding" a game for a family member on my personal time. Something inspired by a blend of 'Recettear' and 'Stardew Valley' with the touch that the player shopkeeper is an anthropomorphic cat.
Sorcery - open source app and protocol that, together, let you share source code links that open in each user's favorite editor, right on the linked line.
Supports VS Code, Neovim, IntelliJ/JetBrains Family, Zed, etc.
About to do the first beta release this later this week.
AskUCP ā UCP protocol explorer showing all products on Shopify (https://askucp.com/)
On January 11th, Google and Shopify announced the Universal Commerce Protocol (ucp.dev). It's an open standard that lets any application query products across e-commerce platforms without needing APIs, integrations, or middlemen.
AskUCP is one of the first applications built on it.
Right now, if you want to buy something online, you have to know which store sells it. You go to Amazon, or you go to a Shopify store, or you go to Etsy. Each one has its own search, its own interface, its own checkout. The experience is fragmented because the infrastructure is siloed.
UCP changes this at the protocol level. If products are described in a standard format, any application can discover them. You don't need permission from each platform. You don't need to build integrations. Anybody or any AI agent just querys the protocol.
AskUCP is designed to be a single pane of glass into online commerce. You search once, and you see products from across the ecosystem. Currently, that means the entire Shopify catalog. As more platforms adopt UCP, their products become explorable too. Eventually, it should be everything.
This is a proof of concept. It's early, and there are rough edges. Let me know what you think, refinements, ideas etc etc.
The end game is no/low touch weekly meal plans send directly to your inbox, with meals you love to cook but with none of the hassle around planning the meals, shopping list etc (which I spend hours doing every week).
An important feature for me was improving the recipe discovery experience, you can build a cookbook from chefs you follow on socials (youtube for now), or import from any source (Web, or take pic of cookbook etc) - it then hastight / easy integration into recipe lists.
Utilising GenAI to auto extract recipes, manage conversions, merge/categorise shopping lists etc - as-well as the actual recommendations engine.
If anyone is interested in beta testing / wants to have a chat I'll look out for replies, or message mealplannr@tomyeoman.dev
Humetrical ( https://humetrical.com ) -- A wellness platform that puts people's mental health first by showing work metrics that matter. Because burnout blindness leads to exit interviews.
It wasn't until we had a leadership retreat at my day job with a fantastic speaker (Woodrie Burich) that the idea for my platform spawned. She talked about how the $50B wellness industry is doing it wrong. Your company is giving you useless yoga stipends, when truth is they should be paying attention to your overall well being. One idea she presented that resonated with me was using a traffic light-like system to gauge where your employees are mentally at.
I took that to heart and verbally applied it to my team. Then I realized that a platform would give better visuals of the data and be easier to incorporate into everyone's day to day. A couple months later I finally released it.
Itās a tool that leverages your drm free ebooks to help manage your book clubs. The epub file offers more rich info such as:
- word counts per reading
- chapter selection
- the ability to highlight sections and share
- ai summarization and spoiler free discussion about the contents of a given reading
I use it for my own book club right now. I doubt Iāll be able to monetize the app due to the need for drm free epubs which is a pretty high barrier for entry to most non-technical users.
My long term plans would be to have an agent help readers learn hand in hand while reading. Iād like to have the agent facilitate deeper analysis by prompting the users and clubs with questions that encourage more critical analysis of each section. Iāve been building all the infrastructure for running the club so thatās the next more interesting step I havenāt explored yet.
I'm working on lots of projects. My favorite is what I call "context bonsai" where I'm giving LLM harnesses the ability to surgically edit the context. It's available as a tool. You can say "remove that failed debugging session and write a summary of what we learned." Or you can take a more hands-on approach and say "remove messages msg_ID1 through msg_ID2". The removal leaves a summary and keywords, and the original messages can be pulled back into context if the LLM thinks they're useful.
I would really like people to try it out and report bugs, failures, and successes.
I'm currently trying to get the LLM to be more proactive about removing content that is no longer useful in order to stay ahead of autocompaction and also just to keep the context window small and focused in general.
I find it fascinating to give the LLMs huge stacks of reflective context. It's incredible how good they are at feeling huge amounts of csv like data. I imagine they would be good at trimming their context down.
I did some experiments by exposing the raw latent states, using hooks, of a small 1B Gemma model to a large model as it processed data. I'm curious if it is possible for the large model to nudge the smaller model latents to get the outputs it wants. I desperately want to get thinking out of tokens and into latent space. Something I've been chasing for a bit.
Yes - I think there is untapped potential into figuring out how to understand and use the latent space. I'm still at the language layer. I occasionally stumble across something that seems to tap into something deeper and I'm getting better at finding those. But direct observability and actuation of those lower layers is an area that I think is going to be very fruitful of we can figure it out
I'm sure you're aware but it's worth pointing out that you will lose all your cache hit discounts with some providers. The next turn will incur the cost of the whole trajectory billed at fresh input token rates.
As an aside, 95 pages into the system card for Claude Opus 4.6, Anthropic acknowledges that they have disabled prompt prefill.
Yes, I have already made deliberate cache decisions and plan to do more once it's working the way I imagine. I think the trimmed down context will have way bigger effect than the cache stuff, though.
As far as I understand, it's caches are not a "next-turn" thing, but a ttl thing.
I made the "retrieve" tool, which is what pulls back previously removed content, append to the conversation rather than putting it back where it previously was. But it's a but premature to really know if that's a real optimization.
I've been on and off attempting to reverse engineer old Sierra games in Godot.
I've brought in AI to build tooling to speed up asset extraction from the old game files which has been a huge help. I just got building placement working last night which was a huge win.
This is part of a small hobby where I try to recreate aspects of old games myself to see how I would implement them. I eventually hope to have the skills to create the kind of game I miss playing when I was a kid 30 years ago.
I've been building several things lately in my spare time:
- After Actions (https://www.afteractions.net/) - The company I work for pays for retrospective software, and I figured I could make my own. So I did! Good for agile retrospective ceremonies
- Data Atlas (https://www.data-atlas.net/) - Right now, it's a basic JSON Schema form builder with a UI on top, but I intend to expand it and improve it to be more than that this year.
I've been working on a BuddhaBoard-like app and a few other projects, but nothing I'm prepared to share right now. Maybe next month :D
Bitwit: Learn CS, logic, and math theory (_not_ DSA) with spaced repetition: https://bit-wit.com/
I was hit by a big wave of depression last year. That crisis gave me a couple of periods of hyperfocus, and I thought I might as well use them to try to improve my mind and my ability to reason.
I haven't had good results learning certain subjects, like CS/math, with Anki or other flash card systems. The only thing that ever seemed to work for me was doing a lot of problems with pencil and paper. But without problems exercising those tools or techniques, they tended to just evaporate from my mind.
So my idea was to combine spaced repetition and problem presentation, and create a system for generating problems and validating their solutions randomly and parametrically. So successive presentations of the same card would present a different problem... and the overall effect would hopefully be that you learn the invariants that each card is trying to present, instead of memorizing some combination of variables and values. Sort of MathAcademy but for CS.
I _think_ it's feature-complete at this point, though I'm still working on validating and publishing cards (and there are a couple of things I wanna do to improve security). I'm pretty early in the dogfooding process, and I'm still the only person using it, and there are definitely bugs. But if anyone would like to try it out, I'd be delighted to hear your feedback (email in profile, also on site). Just maybe go a little easy on me right now, lol :/
The Boolean Logic and Lambda Calculus subjects are free forever, and the first topic of each other subject is also free, so if you're intrigued you can use it for quite some time (literally months) before even needing to provide an email address. No need to pay for anything.
Iāve been exploring graph theory and built Overtone, an interactive graph that maps musical artists, genres, albums, labels, instruments, and their relationships using MusicBrainz data. This spun out of a separate graph-based fraud-detection project that I hope to introduce on HN sometime soon.
Itās a beta, but already works well on desktop and makes it easy to explore musical neighborhoods and discover new artists by traversing the graph.
Here's the link in case you wanna find some new music to listen to, or look at the artists you know and love in a different light - https://overtone.kernelpanic.lol
Feedback welcome ā especially on UI/UX and scalability limits.
I've been building VVM: a language for agentic programs where the LLM is the runtime.
Most stacks today keep orchestration in Python/TS and treat the model like an API. VVM inverts this. You write a `.vvm` program, paste it into an agentic session with the spec, and the model simulates the VM and executes your program. This is configured via a plugin, no SDK or build step required.
papers = @researcher `Find recent papers on {topic}.`(topic)
# semantic predicate ā semantic if condition
if ?`sufficient coverage`(papers):
report = @writer `Synthesize findings.`(papers)
else:
papers = @researcher `Expand search.`(papers)
export report
```
It's open source and current runs as a Claude code plugin and the repo includes 37 examples from basic agent calls to advanced patterns that showcase building resilient workflows.
Still pre-alpha -- the spec is fairly complete, but tooling is early. Mainly looking for feedback from people building agentic systems who've felt the impedance mismatch between imperative code and what agents actually need.
Working on a little "passion project" that has ended up consuming a lot of weekends now, but it's been a lot of fun.
I've been building https://photoweather.app because I never end up having time to look at weather forecasts, which means I also don't go out with my camera enough since outdoor photography is quite a weather dependent activity.. so I'm trying to turn this around by having the app tell me when and where I could be photographing instead.
It's a bit of a challenge for sure, weather forecasts are not always the most reliable, not to mention learning enough about weather to forecast photographic opportunities.. but it's also been really enjoyable to finally build something real and something that I myself actually use all the time.
I often have ideas, then spin cycles on starting the project, getting auth in place, making a marketing page, doing SEO, building and configuring pipelines for mobile app release, etc, etc.
My project builder just takes a name, a few configuration options (do you need payments? Analytics?) and spits out a templated build with Terraform that I can 1 (okay maybe 3) click deploy to GCP + App Stores.
The nice thing (I got help with Claude Code) is that now all my projects are in one place, I have a dashboard where I click in to and edit the code (with hot reloading - it deploys code-server and the applications in a small Kubernetes cluster, each project has its own pod) and when I am done editing I just click Deploy and it updates the "production" service in Cloud Run.
Not really interested in selling it as a service or anything (it's a bit too opinionated for that), but it's a very fun project to work on. I need to make Git + Versioning of the code work right now you only have a single copy of the code which isn't great!
back working on my lighting desk, after a couple of years of hating it because the communications bus between the many different modules was flakey and so the whole thing wasn't fun to use. I bit the bullet last year and re-implemented everything with CAN-bus communications and it's actually fun to use now.
Current work has been improving boot time. Was nearly two minutes because of one board, and that's a long time for the lights to be out if you have to reboot during a show. I'd wanted to use buildroot to get a custom kernel that should boot much more quickly, but the buildroot learning curve was steep for me, particularly as I've no expectation of ever needing the knowledge again.
Independently but concurrently I decided I really ought to understand what all this AI stuff was about, for fear of getting left behind. That coincided with the release of opus 4.5, and holy heck has it made a difference! With a little guidance from me Claude got the buildroot environment working and the boot time down to less than 10 seconds. I've been _really_ impressed. I've had Claude write a few boring utilities that I could easily have done but Claude managed much faster and with less boredom on my part. Fortunately for my AI revolution I think I'm a better Business Analyst/writer than I am a coder, so it fits with my temperament.
Different RSS clients provide different filtering options, and lots of them limit you to a few keywords and/or put them behind a $7-12/mo subscription. I'm building Sponder so you can curate what you see, and it just presents another RSS feed, so you can keep using your favorite client but fill in the feature gaps.
Right now it can merge and filter by string or regex, and next I'm building (because it's what I want) history replay and smarter podcast rerun detection. it's new and I'm very open to feedback and feature requests.
It is capable of creating a PCB (and outputs gerbers, bom, pick and place files), an enclosure (written in SCAD, outputs an STL for printing), and firmware, which it's able to compile using a pio runner on railway and provides a binary, but also has a webserial flasher for ESP32's.
There is a blog here, but i've been focussing on getting things finished, as I built it for a hackathon ending today.
I need to update the blog & writeup, because I have the first product it created, a bluetooth remote control. It wasn't without issues, but I have a working PCB, in an enclosure that was printed from it's design, running firmware it generated.
Hi HN, I built this because I got tired of fighting with integrating payments in Africa.
M-Pesa processes over $300B annually, it's how 50+ million people in Kenya pay for everything from groceries to rent. People don't have bank accounts, but rather pay straight from their cell phone nummber. But integrating it into your app? That's a different story. Most developers spend weeks on what should take hours, it's almost impossible. And existing solutions for Mastercard, Paypal, Apple Pay etc are useless because most don't have bank accounts.
Micropay is essentially what Stripe did for credit cards, but for mobile money.
The next part of the project is Tech Posts Intel: a lead gen tool using statistical methods to predict which companies should have a funding round coming soon. I'm hoping to soft launch it this week.
I'd love to hear anyone's feedback on the website. Advice on how to get inbound links in 2026 would also be greatly appreciated!
Borrow This And Improve It - an app for tracking repairs to a thing (right now it's bicycles only, planning to extend to other things like leaf blowers and electronics) and giving away half broken things or repaired things to others but with the advantage of also giving away the repair history for something. So for example, I found a bicycle in the trash, fixed it up with a few new parts (less than $6) and soon I'll try to give the now repaired bicycle away to a new home, plus a QR code that links to its repair history. The idea being that knowing how something was fixed once will make it more likely that it would be fixed again.
How Home Alone My House - A fun app I'm making with my children using computer vision. The idea is I can scan the room with my camera before unwittingly walking into their traps and becoming a hapless adult who didn't pay close enough attention to tripping hazards and choke lines.
Lately Iāve been interested in how budgeting apps model cash flow over time. A lot of tools are either expense trackers or monthly budgets that assume clean month boundaries, which breaks down quickly if youāre paid biweekly or irregularly.
Envelope budgeting (the method) works by allocating money up front so future obligations are actually covered before spending happens. But the hard part is handling income timing and paycheck variability without overfunding the future.
Anyways, Iām currently adding a cash flow detection algorithm to Envelope (the budgeting app) https://envelopebudgeting.com that only allocates paychecks to obligations before the next paycheck unless future funding is strictly required. That approach has avoided a lot of timing edge cases I kept running into.
Iām working on tabularis, a lightweight desktop database management tool designed for developers. It provides a modern interface for managing MySQL/MariaDB, PostgreSQL, and SQLite databases through a native desktop application. Built using Tauri v2 (Rust backend) and React 19 (TypeScript frontend), it offers native performance while maintaining the flexibility of web technologies.
Keep working on MatGoat (https://matgoat.com/en/) - management software for Brazilian Jiu-Jitsu and other martial arts' academies.
I train BJJ and kept hearing the same pain points from academy owners regarding attendance tracking, communications, missing payments, etc.
So I built a tool for martial arts academies in 2024 with belts progression, automated payments, attendance tracking, and a tablet check-in system. Nowadays I'm still onboarding new academies every week and working a bit more on the marketing side to keep growing.
Building ExoAgent: a security layer for AI agents that enforces data flow policy, not just access control.
The problem: agents like OpenClaw can read your email and post to Slack. Nothing stops Email A's content from leaking to the wrong recipient, or PII from ending up in a Slack message. Current "security" is prompts saying "please don't leak data."
The fix: fine-grained data access (object-capabilities) + deterministic policy (information flow control). If an agent reads sensitive data, it structurally can't send it to an unauthorized sink. Policy as code, not suggestions.
Got a working IFC proof-of-concept last week. Now building a secure personal agent to dogfood it.
What integrations would you want if privacy/security wasn't a blocker? What's the agent use case you wish you could trust?
In my evenings and weekends I've been working on a photo sharing app for families who want to keep their photos off of social media but still share with family.
I'm expecting my first child soon so I am building it for me and my family first but if it solves a problem for me, maybe others will like it!
The basic idea is that you are uploading a curated set of photos you want to share, not your whole camera roll.
You can create one or several family groups that you can share individual photos or albums to. Members of those family groups can view, comment on, like, etc those photos.
You can also generate sharable links for people who don't have an account with a configurable expiry time.
It currently more or less works on the web but I am also working on iOS and Android apps since that is how my extended family would want to interact with it.
I'm not quite ready to launch it to the public but if anybody is interested in trying it out or offering feedback I can privately share it :)
Nice. I store my photos on Dropbox and now duplicated locally on a home NAS. They don't have a photograph based product like Google memories, which I really like. I've been de googling and looking to reproduce it.
I've been noodling with running a preprocessing step to "tag" pictures and videos with a set of tags with richer spatial and temporal features with off the shelf models and then just let a local AI model pick one based one what might match today's theme.
Are you using any models to make your curation step easier/better UX wise? e.g." Compose all Christmas pictures with Grandma and the kids on vacation" and it would give you a collection to curate from my library
One of my priorities is end user privacy so I'm trying to minimize how much access my service would have to the users library of photos.
Rather than me scan all of the photos I'd prefer the user manually select them. Plus, you get the bonus feature of also getting to review your own photos again :) I find a lot of the time I never go back and look at photos I take. I'm trying to evoke feelings of printing photos and putting them in an album. Digital is no substitute for physical, but if I can get close I'll take it haha
I am considering some ease of use features like library scanning / tagging maybe on an opt-in basis perhaps.
- A phoenix/ecto inspired batteries included framework for Golang. Uses data-star for real time bindings (can do live view like things but my personal favorite is just real time form validation out of the box). Hot reload with templ, daisy, and tailwind (no npm required). Routes file provides metadata on routes so type safe route helpers are generated for views and handlers.
A high-performance 3D game engine and editor in Rust. It has the ability to deploy to WebAssembly and WebGL2, delivering console-quality visuals and near-native performance right in the browser.
Currently building a multiplayer cozy farming game, inspired by Animal Crossing. Reach out to our discord if you are interested in learning more: https://discord.com/invite/mHsQayQNdp
Can't really share any useful link at the moment, but Iāve been working on a solution based on the C1001 mmWave sensor. It collects telemetry throughout the night, including respiratory rate, heart rate (BPM), number of turnovers, apnea detection, and overall sleep quality - you just need to hang it around the bed. The data is sent to a server, which generates a nightly report and passes it to an LLM for analysis.
I've decided to do it simply because of my grandmother: she dislikes bracelets and smartwatches because theyāre uncomfortable and she often forgets to wear them. A contactless device could be much more practical for her and for many people like her.
I'm one of the maintainers of PGlite - PostgreSQL in WASM.
We have lots of updates in the pipeline, just listing some of them:
- making it easier to upgrade PostgreSQL's version
- PostGIS - this is one of our most requested extensions and although we have it running server side (ie node, bun, deno) Chrome is holding us back from releasing it
- multi-connection multiplexing over a single instance
Native library is also on our radar, just needs more time...
Iāve been experimenting with a live win probability predictor for the 10-player arcade game Killer Queen. The goal is to predict the winner in a causal, event-by-event fashion.
Right now Iām struggling to beat a baseline LightGBM model trained on hand-engineered expert features. My attempts at using a win probability head on top of nanoGPT, treating events as tokens, have been significantly worse. I am seeing about 65% accuracy compared to the LightGBMās 70%. That 5% gap is huge given how stochastic the early game is, and the Transformer is easily 4 OOM more expensive to train.
To bridge the gap, Iām moving to a hybrid approach. Iām feeding those expert features back in as additional tokens or auxiliary loss heads, and I am using the LightGBM model as a teacher for knowledge distillation to provide smoother gradients.
The main priority here is personalized post-game feedback. By tracking sharp swings in win probability, or $\Delta WP$, you can automatically generate high or low-light reels right after a match. It helps players see the exact moment a play was either effective or catastrophic.
There is also a clear application for automated content creation. You can use $\Delta WP$ as a heuristic to identify the actual turning points of a match for YouTube summaries without needing to manually scrub through hours of Twitch footage.
I used to play very competitively, but I've been more chill recently. I just think it's a nice problem/dataset to work with, because of the depth of my understanding of the game.
You tap in what ingredients youāve got, add a time limit + a couple of preferences, and it gives you 3 genuinely doable dinner ideas with step-by-step recipes (no āmanage your pantryā, no endless scrolling).
Many mainstream email providers have switched to require OAuth for login, but there are tons of clients and apps that donāt (or canāt) support OAuth.
Auth-Email is a secure, private relay that takes out the need to worry about OAuth: authorize mail accounts one time in our dashboard, then use an ordinary username and password for IMAP, POP, and SMTP via our server.
The problem: if you use multiple AI tools (Claude, ChatGPT, Cursor, etc.), none of them know what the others know. You end up maintaining .md files, pasting context between chats, and re-explaining your project every time you start a new conversation. Power users spend more time briefing their agents than doing actual work.
Memory Store is an MCP server that ingests context from your workplace tools (Slack, email, calendar) and makes it available to any MCP-compatible agent. Make a decision in one tool, the others know. Project status changes, every agent is up to date.
We ran 35 in-depth user interviews and surveyed 90 people before writing a line of product code ā 95% had already built workarounds for this problem (custom GPTs, claude.md templates, copy-paste workflows). The pain is real and people are already investing effort to solve it badly.
Early users are telling us things like one founder who tracked investor conversations through Memory Store and estimated talking to 4-5x more people because his agents could draft contextual replies without manual briefing. It helped close his round.
Live in beta now. Would love feedback from anyone who's felt this pain! :)
Iām building an AI emotional regulation coach for autism
Traditional therapy assumes you can identify what youāre feeling, which is exactly what many autistic people struggle with. Anna, the emotional regulation coach, addresses this dilemma.
Iāve used her daily for nearly a year and havenāt had a major dysregulation event since. Now Iām working on developing Anna further. The following post includes a detailed framework for building your own.
A django-based "offline" social media platform (i.e. forum) designed for access only from a single (isolated) WiFi network via captive portal techniques. The goal is a "digital bulletin board" that is geographically isolated and community-moderated (think Reddit's karma system but enough down-votes will delete your post).
Not anywhere near production-ready yet but if this is up your street and you want to contribute then I'd be grateful! I have the back-end stuff well under my belt but I'm allergic to javascript and my CSS skills are pretty limited also.
Also in the works down the line: a simple document management system (another Django app, probably) that allows basic but ISO-compliant document control (centralised access controls, automatic document-numbering, review/approval and draft/issue processes, configurable document indices, etc.) aimed at SME or contractor use. Everything else I've tried in this category of software is either abandoned (or otherwise stuck with a tech-stack from nineties), active but a PITA to ensure ISO-compliance, or hugely over-complicated (i.e. ideal for a big corpo but too much admin overhead for an SME) so I'm brewing my own that aims to meet the minimum feature-set needed for easy ISO-compliance.
I'm working on a (somewhat) realistic surfing game. Tired of arcade-style games, I decided to try my hand at something closer to the real sport, focusing on realistic breaking waves, speed generation and carving, rather than impossible air combos.
After one year of development, it's going better than I expected, so I'm considering building a demo to gather feedback and see if there's enough traction for working towards a Steam release.
Even if that's not the case though, it's been a blast learning about game dev in Unity/C#, as well as 3D modeling and animation in Blender!
Hi I'm a big surfer (or have been most of my life but doing less now at 40!) also building a mobile game in Unity/C# right now although it's not surf related like yours it's actually based on Chinese Wuxia cinema from 5 years spent in China. I considered building a surf one and was looking at potentially trying to 'gamify' a slightly different element of the 'surfing' experience which was to focus on predicting/catching and then staying on a wave at a busy break...so top down early GTA style graphics initially waves would come almost breaking in random spots in relation to previoius waves/sets, but never identical, and you'd have to kind of 'guess' ahead of other AI controlled surfers where to place yourself then paddle for position then try to dodge others on the way in....I thought it could be kind of fun in an arcadey way and not require so much of the physics you're describing, which is no doubt really hard to code...I'd love to see your game though!
I believe realistic fluid dynamics in the scale of a full breaking wave is unheard of for real time graphics, there's just no way to do it in 30-60FPS (I could be wrong tho!)
What I do instead is to transform a procedural plane mesh into wave-like geometry. For added realism, I base this transformation on bathymetry data (ocean floor height), so you can get left/right breaking waves, different breaking sessions, etc, just by defining different heightmaps.
KSPS was my favourite surfing game growing up. What I dislike about it though is the infinite/perfect waves (always a truck-sized barrel opened, you can do tricks anywhere, almost no differentiation between waves) and the focus on impossible airs and tricks.
In my game the waves start, break and end, with different sessions and hollowness, so there's more wave reading involved. Also the focus is on being able to stay on the wave and generate speed, doing cutbacks, snaps, off the lips, etc.

Another Web-OS remake of Windows 98 made with vanilla JavaScript. There are already a lot of Windows web remakes, especially in this age of AI. So for this passion project I intend to make it as accurate as it could ever be without having to emulate actual Windows 98.
Currently it has:
- Accurate recreation of Windows shell with start menu, taskbar, windowing system.
- Full desktop themes customization (color, cursor, sound, wallpaper, screensaver). All Win 98 default Plus! themes are included.
- Persistent local file system & mounting local folder as removable disk with ZenFS.
- Support playing Flash games and run DOS games (save game persisted). Yes, you can play Doom and copy your savegames to continue.
- Some accurate remakes of Windows 98 apps, some made by me (Solitaire games, Minesweeper, Notepad) some are existing ports (Pinball, JSPaint, Webamp, etc).
- Some other fun stuff
If you're interested in Windows 98, this is for you. You're also welcome to contribute or fork it to create your own version: https://github.com/azayrahmad/win98-web
I'm working on a language learning framework based on the ideas of comprehensible input and spaced repetition learning.
The idea is you take a book you want to read, and it gets translated but also rewritten to match your current learning level. And as you read/listen it introduces new words to learn, reinforced by spaced repetition.
We're taking a trip to France this summer and I'm hoping to have something usable for at least a couple months before we go.
Currently working on the mechanics of extracting content from ebooks.
A pricing API for the Counter-Strike 2 market that provides real-time & historical data.
The market is distributed across a bunch of 3rd-party marketplaces, and there's no 'simple' API that provides genuinely high-quality data. It's been a super fun project, and I've been able to learn about collecting & managing a high (to me) scale of data, building an API from the ground-up, and creating my first 'commercial' website.
Iāve been iterating on Toolbit (https://toolbit.app), a local developer utility app I initially shared a while back.
It started as a small attempt to stop bouncing between dozens of web tools for things like JSON/JWT, base64, regex testing, cron expressions, and similar āglue workā tasks. Over time itās grown into something I keep open all day.
Since the last time I mentioned it, Iāve added quite a bit:
ā¢ ~40+ tools now (regex tester, PDF merge, image conversion, cron builder, etc.)
ā¢ workspaces for grouping tools around a task
ā¢ tool chaining instead of constant copy/paste
ā¢ snippets, history, and recent items
ā¢ automatic detection (paste data, it routes you to the right tool)
Itās an Electron app and runs fully local. No accounts, no tracking, no sending data out. The goal isnāt novelty, just reducing friction in everyday dev work.
Iām still smoothing rough edges and figuring out where this is most genuinely useful. Curious how others here think about scope creep vs. ādaily driverā utility tools, and whatās worked or failed for you in that space.
A pro bono tech consultancy for local non profits. The idea is to help them use tech to better deliver on their mission.
Just today I finished off building a little PWA to help a couple of non-profits offload the admin of volunteer scheduling (mostly done through whatsapp, messenger, etc).
I'd recommend others try the same pro bono consulting in their local area, it's quite rewarding!
I've been having a lot of fun modding 7 Days to Die (zombie game) using Claude Code. I have a strong development background but I've never worked on games before. Without AI it would be completely inaccessible to me without months of catching up.
7DTD is built on Unity Engine and modding is mostly done with XML/XPath and C#. I have yet to install Unity. I have a CLI setup, including a script to disassemble relevant 7DTD assembly DLLs into C# and copy other info from XML files into a directory in my repo.
This "refs" directory has about 800k lines of C# code and 300k lines of XML. Claude can figure out how to add a feature or fix a bug with a few minutes of searching the refs. At first it took 5-10 attempts to get results that actually worked, but now it's often 1-3.
Here are the mods I've released since early Jan:
- SteelUI: fixes for it to work with the latest game version[1]
- Smarter-Tools: a mod I authored from scratch to add a few tweaks to how tools work[2]
- More-Gore-Continued: has serious performance issues I'm working on - making progress[3] (adult only - requires sign-in)
If there's any interest I'm considering writing up all the details in an article and making the mod repos public.
I have been through a number of iterations of adders, integratorsā¦ It's starting to coalesce now into a finished PCB. (Iterating is slow though at the PCB stage since we're round-tripping via Asian PCB fabs.)
As often happens, I want to learn about something (analog computing in this case) and I find that a deep dive where a kit comes out at the end is an enjoyable way to explore (I also get more experience with KiCad and, for this project, SMT).
The seed of this were a few articles on building a "lunar lander" circuit in early '70's electronic hobbyist magazines I found online. Pre-home-computer, how does one create a lunar landing simulation? Why with op-amps and panel meters of course.
And so that is where I began. But I'm way past that now though by making instead a general purpose analog computer.
Building PushMe: A service that sends you notifications for anything you care about.
I was wasting way to much time scrolling news. It consist of a crawling engine, de-duplication, llm creating a custom keyword filter and each event is checked against the original prompt for verification using a llm before sending it out.
Keywords suck, 381 of 388 potential matches end up like this:
"The event is about an OpenClaw Plugin Hub supply chain attack, not a data breach affecting hundreds of millions of users. The watch request specifies a massive data breach; the event does not clearly indicate that."
Working on Whisperit v3: a document automation platform for lawyers, voice-first.
The idea: lawyers spend 60%+ of their time writing documents. We give them an AI assistant that actually understands legal context ā case files, templates, emails, the full picture.
ā¢ Case-context AI assistant ā docked right into your case view, with file attachments, skill system, and next-action suggestions. It knows your case, not just your prompt. Think Pipedrive CRM for lawyer!
ā¢ Skills system ā modular prompts lawyers can pick and inject (summarize deposition, draft motion, extract key dates, Claude Skills, etc.)
ā¢ Cloud drive sync ā bi-directional sync with Google Drive and OneDrive. Lawyers keep their existing file setup, we plug in and keep everything in sync
ā¢ Outlook, Gmail, IMAP email integration ā connect your inbox, pull relevant emails directly into cases
ā¢ Template multi-output generation ā one case, multiple documents generated in one flow
ā¢ BYO AI provider ā user/workspace/admin level settings for AI models. Some firms want Azure, some want Anthropic, we let them choose
ā¢ Canvas boards with AI context for visual case planning
Stack: Next.js 16, FastAPI + LangGraph backend, Supabase.
We're a small team in Switzerland and across the globe, shipping daily. Target is Q1 for the v3 launch. If you work in legal or know lawyers drowning in document work: would love feedback or test our beta :)
What did you use to record the video on the home page, if you don't mind me asking? I need to do something similar. One tip I've seen is to record at a higher resolution than you need, then scale down. The demo is good, but looks a little grainy at points, FYI.
Of course! I have looked into many tools to be able to do that properly. This one was done with Screen Studio, which is one, and there is another one that is nice and open source: Cap - but a bit less features.
We trained PyTorch models on solved poker scenarios for post-flop, turn, and river situations.
The planned "killer feature" is to give users feedback on their poker play in the flow of a simulated poker tournament or simulated cash game scenario. The goal is to play against "GTO Bots" (Game Theory Optimal Bots) to learn how to play closer to GTO.^1
Poker has been a passion of mine for a few years now, I find the game incredibly intellectually stimulating as well as a tremendous catalyst for personal growth, and this project has been a great way to channel that energy.
The web app uses Django/Channels/WebSockets. We've built an internal discounted CFR solver as well, hopefully building up to multiway scenarios in the future. The webapp is still in Beta/gated, and you're interested in learning more please email contact at surlesol dot com.
We are thinking of pricing $8/month or $74.99/year, with the rationale that this will be far less expensive than learning by experience at even micro stakes for online poker, with better feedback for learning, and at least we make it explicit that you're competing against bots ;-)
1. I am aware that GTO play is not always optimal, especially in live poker where live tells are available, and often exploitative strategies fare better than pure GTO. The target audience for ComputerPoker.ai is not hardcore poker pros, there's plenty of existing software for that, but rather those individuals looking to get acquainted with what GTO play "feels like." Then, with this knowledge in hand, knowing what the GTO play would be given various assumptions about our range and a reasonable opponent's range, we can deviate from the GTO play as deemed necessary.
I have been working on a web app called Beval - Simple evaluations for your AI product.
In my day to day as a Product Manager working in a team that ships AI products, I often found myself wanting to do 'quick and dirty' LLM based evaluation on conversation transcripts and traces. I found myself blocked by 'Gemini in Google Sheets', it was too slow and cumbersome, and it didn't handle eval changes well. And because I was exploring, it wasn't helpful to try and set up something more robust with the team.
To fix the problem I eventually learned to call the OpenAI API in python, but I really felt that I wanted a 'product' to help me and potentially help others.
The second bubble there is a tool for 3D visualization and analytics of Claude Code sessions. The sample conversation is the one that made the tool itself!
That was a fun toy I learned a lot from. Iām not expanding that but am working intensely on the first bubble:
thinkt a CLI/TUI/Webapp for exploring your LLM conversations. Makes it easy to see all your local projects, view them, and export them. It has an embedded OpenAPI server and MCP server.
So you can open Kimi and say āuse thinkt mcp to look at my last Claude session in this project, look at the thinking at the end and report on the issues we were facingā.
I added Claude Teams support by launching a Team and having that team look at its own traces and the changing ~/.Claude folder. Similar for Gemini CLI and Copilot (which still need work).
Doing it in the open. Only 2 weeks old - usable, but early. Iām only posting as itās what Iām working on. Still working on polish and deeper review (it is vibe-crafted). Thereās ergonomic issues with ports and DuckDB. Coming up next is VSCode extension and an exporter/collecter for remote agents.
Over two decades ago I was diagnosed with high blood pressure (for which am I have been on meds for about 15 years). I also have low platelets (red blood cells, basically means that I bruise easily and that small cuts don't heal fast). At any rate, I do blood tests on a regular basis to keep things in check. I have been keeping track of test results, weight and blood pressure result for nearly 20 years, but the data lives in a text file on my desktop. I wanted to build something more substantial for this for quite some time now, so, this is it.
I always wanted a minimalistic CSS framework for my projects, so I started to create my own: THINK
THINK is a modern CSS-first UI framework built on semantic HTML, custom elements, and data attributes. Uses :has(), container queries, and density scaling. No classes, no build step.
Itās work in progress but Iām pretty happy with the outcome so far, especially the data table component and automated Insights. I know itās not AI driven - but it works pretty okay for quick insights on the loaded data.
Video Reject is a platform for people to buy/sell physical media. Like Reverb but for physical media.
I love movies and wanted an excuse build something in that world. Its not necessarily groundbreaking, but I think it could build a nice community of folks with the same interests.
We're getting ready to launch, but in the meantime, we have a waitlist up.
- A stair lift for stuff, not people. Retrofits onto any stairs and self-locks without damaging the stairs or blocking the path. Allows you to bring groceries, laundry, senior dogs up and down stairs with the push of a button. Currently can pull 50lbs.
- A bracelet with tiny camera that's pointed at your hand palm and transmits pictures of the stuff you're holding and where you've put it down locally to your phone. Pictures are sent to a quantized CLIP which allows you to search for anything you've lost without needing to attach an airtag to it. Works decently well and is great for 'power losers' like those with ADHD-I. Has a privacy slider and nothing goes to the cloud.
Would love to hear from anyone interested > hi @ hitch-home dot com
Building TimeCap: an app that removes the addictive sections of any social media. That means that you can check your friends' updates on Instagram without getting distracted by reels.
It is fully customizable, works on any social media, and it genuinely brought my screen time to less than 1 hour.
It is free to use for one platform, and is $29.99/yr for unlimited. And if you need the premium version but can't afford it, just send me a message and I'll sort you out.
Weāre aiming to build the best typing application; personalized to every users typing habits.
Typing is one of the most important hard skills today and yet most education systems skip it.
Most of our customers are adults who always wanted to type but canāt find the time. We make it faster to learn and improve by focusing around the userās weak points (with our features like SmartPractice and TargetPractice)
I've been working on a browser extension to make Hacker News easier to use. No, not change the UX, but just some nice conveniences. Keyboard navigation, inline replies, dark mode, a nicer topcolors page, and many more features. I am hoping to add some social features, like being able to follow someone. All in a well-tested and extensible codebase that has minimal impact on the site. Open source, GPL...
Sounds great! I've been thinking about making something similar now for a while.
If you don't mind me sharing ideas that I would love to have in such an extension:
- Changing the UI of the comment actions to make them easier to use. Using HN mostly on a phone, I keep hitting downvote when I mean to do the opposite. Similar with the collapse action.
- Keep a local list of users that get their comment subtrees stripped out. Some people are argumentative by nature and not in good faith. It's best to ignore them (easier when you don't see their comments).
- Hide new accounts by default (perhaps auto collapsed).
So far, desktop is the current target. Not even sure I can run extensions on a phone.
The last two fall under content moderation. I'm a bit less interested in that as it changes the UX and there are infinite things we could do there. Right now, the extension has no preferences switches, and I'd like to keep it that way for as long as possible. When there are a whole bunch of knobs to tweak, it makes everything overwhelming.
Developing LogiModel AI (https://www.logimodel.com/) which is an agentic supply chain optimization engine that forecasts demand, optimizes operations, and simulates scenarios to reduce costs while keeping your network reliable and customers satisfied. It integrates seamlessly with your ERP and document repositories to learn your business context, then acts as an intelligent decision engine, freeing you to focus on strategy while it handles execution.
Always interested in possibilities of LLMs interfacing with MIP solvers.
I'm building a tiny experimental message board / ...game? called Isles (https://isles.app/about). The short pitch is that when you sign up you're randomly assigned to a small island, and you can only interact with people on that island. Randomly, islands link up and you can migrate/explore the other island. I wanted to play with ideas of cultural exchange on a really small scale. I don't have any regular users yet, but if any of that is interesting to you, you should sign up if only to say hi.
Tech I'm using: Sprites, Cloudflare Workers, SQLite, Litestream, React SSR
Iāve been working on https://og.plus, a service that creates unique Open Graph images per page on a website.
It does this by taking a screenshot of the page, but before it does that, you can modify whatās displayed in the screenshot with CSS, tailwind classes, meta tags, or HTML templates.
If you connect your website to it, the only thing you need to deploy to your web app are a few meta tags. The OG+ servers do the heavy lifting of processing the meta tags to setup the page, take a screenshot of it, and serve it up to the consumer.
The other cool thing it does is generate a different Open Graph images per social network so they all get an image for the exact size they works best in their previews. The CSS or HTML templates are aware of this too so you can display different content to specific social networks.
I am working on an app that uses old-school predictive AI (i.e. pytorch and scikit-learn) to predict professional sports outcomes in a way that is useful for DFS fans. Here is the landing page.
We seek to empower DFS fans through education about predicting professional sports athlete outcomes. We do that through strategy advice, hot player tips, optimized lineups, and pickāem style game-friendly player props. We're not trying to take away your control or do your thinking for you. We are just here to support you in making better decisions. Let the app do the number crunching so you can get back to competitive play that gets results and is also fun.
I've just started a new personal project, a C++20 library for running composable visitors over data documents and data models with JSON/CBOR semantics, DOM-less.
Basically, if you define a data model with bindings, you can inject data into it or extract data from it by running SAX-style visitors. You can use serializers/deserializers for standard formats like JSON/BSON/CBOR/CSV, or you can define custom formats for formating structured data however you want to. You can also run a serializer visitor on a deserializer to convert between formats. You can compose filter visitors to extract a subtree or filter out keys. And it's designed to fit on microcontrollers with very limited dynamic memory allocations, because it either streams data on-the-fly or works directly with the underlying data format in a big preallocated buffer.
I worked with libraries that offered a subset of these features before in my professional career (even built one myself), but recently I've had an epiphany (a document can also be used as a data model) that makes me think I can create something elegant and unique.
Inspired by a TED talk I saw [0] where the researcher from Microsoft displayed a program with AI assisting with thinking while someone was reading and annotating a document. They claimed it was a way to sharpen critical thinking instead of killing it. They didn't release the product, but I figured it was cool and useful, so I've spent the weekend creating it. It's been a great way for me to practice using agents, and I've learned a lot from this process.
Biggest challenges:
- How to explain the different use-cases/possibilities in a clear way
- DX for any hacker who comes across the device with/without hardware experience
I'm going through CMU 15-721 and building wsql[1]; a GPU-accelerated query engine. It uses wgpu for cross-platform portability and implements modular pattern, heavily inspired from Sirius[2] paper.
The first AFAIK customer owned self-hosting as a service company. You own the hardware, the software and your data without the hassle of needing to configure or maintain any of it. https://skarabox.com/
Recently, I got banned from Reddit for sharing my local news summarization website (www.cafelutza.ro) - for the Romanian market. So I figured you know what, I've been trying to bring this product to Reddit in the hopes of having better discourse around the news, but instead I realized, I was looking for smart discourse around a subject, which I haven't been able to find on Reddit or elsewhere, so I created Exppit (https://www.exppit.com) that basically gets experts to debate your topic of choice.
I'll admit it's terrifying to share this here because I don't know how to keep costs under control. For now only myself and my friends have used it.
> that basically gets experts to debate your topic of choice.
The word basically is doing a fucking lot of heavy lifting in that sentence given that it's essentially asking spicy autocomplete to pretend it's multiple (possibly dead) people from $field to discuss the topic amongst themselves.
I mean... I'm pretty sure anyone that gives the front page a read can tell that it's spicy autocomplete. The alternative of having Aristotle chiming in to one's shower thought would be harder to explain.
https://radius.to/ - a Meetup.com alternative of sorts - with fairer organiser pricing for smaller groups. I posted a Show HN [1] here a while back, got tons of great feedback, and have been slowly improving it since, with little marketing. Planning a re-launch here soon.
I missed this when it was launched and it's very interesting to see your rationale. If you ever want a chat some time get in touch, I'm working on https://opentechcalendar.co.uk/
My ulterior motive is to ask you to add open data feeds for basic group and event listing information to your site - a free and open API and standard formats like ICAL (Just listings information about the next event, not private info like members names). I would never encourage event organisers to use a platform that didn't do this, as then their data is essentially being held hostage and it's hard for them to spread their information around to other places.
Hey! Wow, I knew about OpenTechCalendar but somehow hadn't realised (or likely forgot) how close to home it was! I'll definitely reach out for a chat at some point.
And thanks for the tips - I completely agree on the point about data being held hostage, and on the openness of data - it's one of the more frequent complaints about Meetup. I've recently added an API for event creation, so it won't be hard to add another endpoint for listings (at the moment, we just have an embeddable widget [1] showing your next 3 events).
ICAL is a brilliant suggestion - I've had a few requests for that already, and it's especially interesting in the context of opentechcalendar. I'm very interested in ActivityPub and all things fediverse as well - figuring out how to integrate these ideas into the platform is one of the next items on my TODO list.
1. Plimsoll Line for dealing with anxieties from mountains of Reminder items, by surfacing the stress factors and taking small actions such as quick journalling and a breathing exercise. The new version with Widget should be released within the next week or two. Version 1 is currently in the iOS App Store. (https://apps.apple.com/us/app/calm-to-do-list-tasks-plimsoll...
Calm To Do List&Tasks-Plimsoll). Made it to help my wife (and me!) not get so overwhelmed with things she has yet to do but hasn't started. Also to make it easy to write down things weighing heavy on her mind to alleviate the vicious cycle of emotional decay.
2. Yet-unnamed and -unreleased weather app for planning outdoor activities at times of the day when the weather will be most favorable (or least bad). Made it so that I can plan when to go out to the back yard to bring in more fire wood for the stove in my house. The weather has been tough this winter in the Northeastern US so it finally made me work on the app.
Tiny desktop (pre)viewer which displays image in transparent overlay without any UI, allowing to look into specific image detail with single hand move (zoom with scroll and pan with drag simultaneously like in map apps, with nothing but display borders limiting visible image surface) and toggle between file manager and image view almost instantly (close with left click anywhere/keyboard Enter).
Also finished initial rewrite in Rust just hours ago:) (originally did it in C and intentionally tried to make it initially close to preceding C codebase before going further, so many things are still managed manually)
Iāve been building out https://hnarcade.com for the past weeks. Got a lot of good feedback from the ShowHN thread and others reaching out individually.
Since the ShowHN thread, I received more than 40 individual game submissions!
To give more exposure to some of the games launched during the week I also launched a newsletter. Feel free to check it out if you want to learn more about games shown over the week :)
The same tech stack is pretty easily adaptable to openclaw tracking. If anybody would like to try, DM
Also looking into AI based security tools for monitoring security of DoneThat. Thinking of using zeropath would love to hear if people tried them / have other suggestions
I built mine with all kinds of privacy features built in: from never storing raw data to always allowing to review before sharing anything to always offering to pause, excluding apps, deleting data, opt-in for social features, ā¦
So spyware in the sense of getting information without the employee knowing would be impossible and not something Iād ever want to do.
It does enable transparency on a very abstracted level: your team could see a six bullet point summary of your day if you opt in. I believe this kind of transparency can actually help more teams go remote, cut down on sync meetings, etc.
Iām currently experimenting with a feature that shows relative time spent only, not absolute - so e.g. 30% on project X, 20% on admin, etc. That could be the sweet spot on visibility vs privacy.
We're working on learning/pedagogy infrastructure that models the learner by using AI to build a knowledge graph: https://parsnips.notion.site/knowledge ā this is in contrast to the common black-box approach of "use some RAG with a large context window and hope for the best".
In the above article, we list a few applications that we think this could be helpful for: life skills, management/sales training, personal coaching, etc. We'd love to demo the software if this sounds interesting to you!
- DietPDF ( https://github.com/Zigazou/dietpdf-haskell ) an intensive PDF optimizer which tries to reduce PDF size as best as it can while preserving visual quality. It relies on a lot of tricks to achieve this goal (minification, precision reduction, deletion of superfluous operations, concatenations, filter combination etc.). At the present moment, I'm trying to implement CCITT Fax encoding/decoding.
I'm working on a website that lists veterinary practices owned by private equity or large corporations to help people make more informed decisions about where they take their pets. It started as a small passion project after our dog (who was sideswiped by a car) died at the hands of a vet practice recently acquired by private equity. We were billed over $13k for 2 days of care where his diagnosis and the opportunity to treat it was missed, there was zero continuity of care, no medical leadership and predatory billing practices.
Thatās a great idea and I wonder if youād consider including the UK. My vet got taken over and now they keep spamming me with āoffersā - so I no longer know if my dog really needs a checkup or not.
Thanks! Actually I did add the UK very recently but this is a good reminder to improve the UI to make it more obvious, if you go to https://www.privateequityvet.org/vet-list/map.html you can toggle between US and UK. I have over 2000 practices listed in the UK.
It's been a painstaking process of combing consolidator websites (eg. PetVet Care Centers, NVA) for practice names, verifying and adding them to a list over the course of over a year. I now get many people writing in to report practices that aren't on the list - admittedly it's not complete list as practices are still being acquired (although independents are now in the minority) and often the old practice branding is kept and the fact it's PE owned is hidden.
https://github.com/purplefish-ai/factory-factory - creating an IDE for managing a swarm of claude agents, and more importantly, increasingly baking workflows into them (e.g. design -> build -> review -> push -> address comments).
Been working on a Bluetooth based miniature range Locating tag that can be glued or stuck on to any object of choice. (think sometohing like an Airtag, but 1/10th the size and working on Android and way cheaper) The need arose when my old parents kept forgetting where they last left their spectacles. Since I am a electronics and hardware engineer by profession, I am looking for some expertise on app building for his project. Maybe I will turn to an AI assistant for this. I am working on a blog seriaes for his to record my environmental progress. Will be up in a few weeks.
For almost 1 year now, we've been building on a next gen event-driven internal developer platform, an an opinionated selfhosted platform "shoehorn.dev" - deploy with ease within 15 min (docker compose or helmcharts). You could say its a modern backstage. But its way smarter in many ways. Kubernetes native, API first, microservice golang backend architecture. You will be able to configure the platform via our terraform provider too. Deploy our kubernetes-push-agent in your cluster, push kinds and auto creates entities into the API in batches, get podEvents etc. Modular frontend written in svelte, decide what you want to show. We're supporting oidc + orgdata sync for okta, zitadel, entraID. rbac management. Instant search using meillisearch. Auto create orgchart depending on how your teams / deparments are nested. Visualize dependencies "relations" using svelteflow. View entity compliance. Full github integration. widget/integration community etc.
I've been working on my newsletter called Tech Talks Weekly[1] where my readers get one email per week with all the latest Software Engineering conference talks and podcasts[1] published that week.
In January, I've released a paid tier[2] where my subscribers additionally get:
1. Access to my internal database of all the talks and podcasts since 2020 (+48,000 in total) where they can search, filter, sort, and group by title, conference/podcast, view count, date, and duration.
2. The list of the most-watched talks over the last 7, 30, 90 days, 6 months, and 12 months based on number of views.
3. Category-based view of new talks & podcasts by tech stack, language, and domain (Software Architecture, Backend, Frontend, Full Stack, Data, ML, DevOps, Security, Leadership and every major language & ecosystem)
Basically tracking where my friends and I have collectively been by dividing the global map into H3 hexagons. The using photo and workout metadata to get the locations, giving points and doing comparisons between everyone. Itās actually quite fun to see random people around the world sign up and see in the global map where everyone has been. Grounds me a bit haha.

A couple different projects. I've been cataloging and publishing my vintage ad collection at https://adretro.com. It's starting to get a lot of organic traffic after about a year online, which is cool.
I'm also working on a new strength gains-tracking app that is a lot more intuitive, motivating and friend first. I've been using it with some friends for the last 10 weeks and everyone making is consistent gains. It is my first full PWA, vanillaJs, backend is Lucee & MySQL. Works great on iOS and Android, no one has any complaints. The web stack has come a long way I am probably not going to do a native mobile app for a while. I'll probably make it public in a couple weeks.
- https://game.tolearnkorean.com/ - Learn Korean words quickly, words go from easy tasks (e.g.) matchings pairs) to more difficult ones (writting it), currently still needs some slight adjustments, and then I'll release an Android version.
- https://app.tolearnjapanese.com/ - Wanted to learn Hiragana quickly, used my existing project as a base to build this. Needs some adjustments as well, feedback is highly welcome.
- https://tolearnkorean.com/ - Since I'm learning Korean, and also working on an app to better learn Korean, I also want to make a guide on learning Korean, improving my own skills by teaching others.
Working on Design Flo - Generate enterprise grade software using natural language. We use 10 years of battle-tested patterns, not just LLMs. Deterministic logic where reliability, performance, and correctness matter most.
BEAM has always been used in high-performance computing applications (Eg. WhatsApp) and Elixir pretty much is the modern Erlang alternative for BEAM, hope this helps.
Started building this after getting nervous about installing random SKILL.md files from GitHub. Scans for prompt injection in markdown/references and suspicious patterns in scripts/.
- 200+ curated skills included
- 33 supported agents
- Symlinks for one install anywhere and automatic updates
- CLI, TUI, or MCP interface: try asking Claude to find and add Awesome repos.
- Semantic search across skill content
Working on: local skill authoring, mise-style directory activation
Couple of utilities for using claude code in my zsh.
#? <describe command> => generates the command for you
#?? <command> => explains the command for you
Packaged as an oh-my-zsh plugin so it's easy to use.
Learning the autonomous coding, there are so many different skills, tools and ways and only some of them seem to work.
That means I have to:
- build something so I can evaluate the results.
- track each of these projects separately otherwise they turn into dust after quite some time. Gladly claudesidian seems to be working well with the unstructured stream of inputs. Feel like hooking it up with some task tracker cli and calendar and notifications could make life a bit better too.
- plan next projects to keep evaluating other skills and tools
Itās been discussed so many times the amount of new or personalized software that appears and will appear and it seems so true.
Whatever I built I am actively using myself - a text rewriter that cleans some of the AI speak and has MCP and cli (at https://www.refineo.app). Math teaching and solving extension at https://math.photos and a self hosted stock opportunity discovery tool that runs locally. This is just to automate what I did before manually and scale it up a bit.
> Any new ideas
Thereās no product yet to cover the needs of all of us launching the software into the internet void. Any ad platform out there is a hot and very outdated mess and I just canāt.
There is going to be a better way with all the capabilities we have and someone is going to really nail it.
Still working on my LPFM radio station, www.kpbj.fm. We launched our regular online stream and have secured a site for our transmitter.
The transmit site is in the Verdugo hills and will need to be off grid. We're going to need about $20k to get the entire transmit system setup (including a solar/battery backup system).
I've also been working on our web infrastructure. The site is built with Haskell and HTMX. The stream is Icecast, and stream scheduling is done using an internal schedule system in the web app and LiquidSoap (so no external tools like airtime, libretime, or azuracast).
Yeah I'm pretty happy with HTMX. I first cut my teeth on programming in the early 2000s with LAMP stack then Ruby on Rails and Django. It feels pretty great to be able to do a web 2.0 style application but still get most of the functionality of a SPA.
From the README: "[git-forge is a] simple CLI tool for basic interactions with issues and pull requests across GitHub, GitLab, Gitea, and Forgejo".
Right now, I am looking into better testing. Currently, I do testing by mocking the forge APIs and then running git-forge against them with TypeScript. But not everything is testable that way. The TUI is pretty much untested. So I now want to port at least the tests to Rust (I am probably gonna leave the mock API in TS) and need to look into how to tests TUIs, which is a bit of a challenge since not only is Rust my first "systems programming language", I am also not knowledgable in Terminal/TUIs...
This is the first time I have seen a post like this on Hacker News.
And I just launched Writtte yesterday, a writing platform for drafting articles with built-in grammar checking and AI-based refactoring with custom styles, and for the first time, with a better copy/paste mechanism for other platforms like Medium, and Substack :D
Open-source RAG infrastructure.Every team I talk to has the same experience: RAG works in the demo, breaks in production.
We handle ingestion through retrieval with optimizations baked in. 97.9% on HotpotQA vs 88.8% for standard RAG. Model-agnostic, 22+ file types, built-in citations, MCP server. MIT licensed.
Just finished "WebGPU path tracer in two weeks" to better understand the benefits of WebGPU over WebGL and generate some pleasing 3D scenes right in the browser.

Hosted OpenClaw, one click and you get a full agent with configurable skills, channels and the whole thing, all running in its own sandbox.
I love OpenClaw but setting it up is a pain: VPS, Docker, API keys in plaintext, security patches... So Iāve spent the last couple weeks building a hosted version that handles all of that. Each user gets their own isolated environment on Cloudflare Workers.
Still doing some testing with friends before opening signups but planning to launch properly this week.
Would love feedback on the landing page in the meantime!
Yeah, itās pretty much ready, Iām just squashing a few last bugs. Launching this week, trying to move fast for exactly that reason.
Good call on the examples, Iāll add some that show off browser automation and more complex workflows.
Memory at launch is whatās baked into OpenClaw, but Iām planning to upgrade it to vectors + a continuously updated doc shortly after (similar to what Claude Web does)
If you want early access Iād be happy to get you set up personally, just shoot me an email at ramon <at> agentmode.co
I've been working on a tool to solve a problem I keep seeing at my day job when handling large-scale deployments and migrations. The āplanā is always scattered across internal docs, spreadsheets, and Slack threads. Coordinating work across multiple teams becomes messy fast
So I'm building Taskplan (https://taskplan.run) - it's like Ansible, but for people. Build a plan, assign tasks to people or teams, and get a real-time dashboard to track progress as the work happens.
I'd love feedback from anyone who deals with the same issues or works on ops-heavy projects.
Chapter (https://jordanful.github.io/chapter/) - a self-hosted ebook reader (server/client) that uses a local TTS AI model for narration. Progress is stored server side, so you can switch from reading to listening anytime.
Visually Iām working on a new landing page for phrasing. Itās almost done, just need to record a few videos: https://phrasing.app/next
Behind the scenes Iām rebuilding the sync engine to properly support offline mode. Trying to get to instant opens for the app (and of course work offline). Itās probably my 5th sync engine. Itās been really fun to see how much easier, faster, better, etc each new iteration is.
(And the project at large is https://phrasing.app - a language learning app for polyglots. Itās like anki but designed to be enjoyed)
The short intro video is helpful in understanding what Phrasing does. The promised walk-though video would also be helpful. I am interested in software for aiding language learning, but after reading your original landing page I could not understand what exactly Phrasing is or what it does. I'm looking forward to trying this out some time this week with my target language. Nice work!
Thanks for the kind words! The promised walk through will maybe come hopefully this weekend, give or take a few days.
Can I ask if the new page explained it better? The ādemo/how it worksā section is still missing the graphics, which I think is pretty critical. But Iām hoping the new page is a bit improvement!
One of the pieces of feedback I get most often from users is āoh this is actually really simpleā. But explaining it simply has always eluded me
Built my own Spotify recommendation egnine after getting tired of Spotifyās repetitive recommendations.
You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created - if you don't follow much or any artists, then you should enable that in order for the service to be useful.
Myself, mostly. Trying to wrestle with realizing how much time I've not been spending on my supposedly main project[1] and questioning whether it's really worth doing.
> Any new ideas that you're thinking about?
Way too many. Writing todo lists is part of working on myself.
[1]: PAPER, a pure-Python ~(pip/pipx replacement), from scratch with an emphasis on simplicity and elegance. https://github.com/zahlman/paper . There's more locally that I haven't pushed, including factoring some stuff out into a separate project and planning more of the same. But yeah.
You know that feeling when your microcontroller crashes and you spend 3 hours staring at cryptic registers trying to figure out why? Yeah, I got tired of that.
So I built an MCP server that lets Claude talk directly to GDB.
Now instead of manually decoding CFSR registers, I just ask "why did it crash?" and get back "division by zero at line 142 in calculate_average()".
It's pretty satisfying to watch Claude diagnose a deadlock between two RP2040 cores in 10 seconds - something that would've ruined my entire afternoon.
A simple HN-like web app that indexes security (and security adjacent) write-ups.
Imagine you, as a security researcher (or any other persona in the security field), wanted to see what prior works are available around bypassing v8 sandbox using webasm, or if whatās been done or found targeting deserialization in Go.
Using this web app, you can search the indexed and tagged write ups.
Also adding MCP support to it so your agents can search too.
Hopefully going live soon.
P.S: I said HN-like, but tbh itās just the UI that looks a bit like HN (Iām not a good designer, so got heavy inspiration from HN listing style), otherwise thereās no other overlap in functionality yet.
Working on MacOS app that detects an active meeting in one of the commonly used apps and then turns on a LED "presence" light. The purpose to let others know that you are "on air" at this moment.
Current release candidate supports detecting Teams Meeting and Slack Huddle.
An on-call runbook execution engine - being able to take plain text runbook steps like
- look at logs for $service, check for dependency failures
- look at so-and-so dashboard.
I got frustrated with existing screenshot services choking on cookie banners, rendering half-loaded pages, and serving bloated images. So my co-founder and I built one that auto-dismisses cookie consent dialogs using Playwright heuristics, serves AVIF-first from Cloudflare R2, and supports geo-distributed rendering so you can capture pages as they'd appear from different regions.
Spring Boot + React + PostgreSQL. Bootstrapped after selling a previous ecommerce SaaS.
Currently documenting the whole build in a 30-day series on the blog if anyone's into that sort of thing.
Iām working on an API that provides heuristic signals about whether a piece of text is likely LLM-generated.
The system uses an ensemble of techniques, and on my internal evaluation set (details below) it achieves ~99.8% accuracy. Iām fully aware that general-purpose AI text detection is hard and adversarial, so this is meant as a probabilistic signal rather than a definitive classifier.
https://finbodhi.com ā It's a personal finance app. It helps you track, understand, benchmark and plan your finances - with double-entry accounting. *You own* your financial data. Itās local-first, syncs across devices, and everythingās encrypted in transit (we do have your email for subscription tracking and analytics). Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more.
Most recently, we added support for benchmarking (create custom dashboards tracking nav and value chart of subsets of your portfolio) and us stocks, etfs etc.
Most parents I've met understand the internet can be a dangerous place for children but aren't sure what to do about it. Some avoid it altogether, but most give up and resign themselves to whatever happens.
What I wanted most was just to have some visibility into what my kids were experiencing, so I built LivingRoom App for iPhone and iPad. It sends occasional screenshots to parents. My hope is that when we shine a light on the online world, we will be free to use the internet as a tool for learning, creativity and connection. https://livingroomapp.com/
Have been working on three micro-saas, all built in Elixir/Phoenix:
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.
https://rizz.farm - a lead gen tool for Reddit that focuses on helping instead of selling, to build long-lasting organic traffic.
https://persumi.com - a blogging platform that turns articles into audio, and to showcase your different interests or "personas".
It gives you clean text summaries of YouTube videos. There are obviously other tools that do this, but I wanted something that is aligned with actual principles of learning and retention, not just quick TLDRs.
Also added a feature called Related Videos. It extracts the key themes from a video and recommends the top 3 related videos, essentially creating a small āknowledge webā of sorts around the topic. Similar to youtube recommendations, but you don't watch you click and read.
You can do YouTube search directly inside the product. When you click a video, it generates a summary. So youāre still browsing YouTube, but click turns a video into something you can actually consume. Personally found it better way to consume youtube, quicker for me to get through the content I want to consume than have those 10+ Youtube tabs sitting in my browser forever.
Thereās also a public library feature I added where you can make your summary public. Itās kind of fun to see what other people are learning.
Still early, but iterating on it, scratching my own itch.
I'm working on publishing a big update to my open source .NET project, ShopifySharp. I recently finished a custom graphql query builder generator (written in some sloppy F#) which will be included in the next release, which means all of the types, queries and mutations in Shopify's graphql schema will have a matching fluent-style query builder in ShopifySharp.
Aiming to get that published in the next day or two, and then I plan on diving in on a complete rewrite of the book I wrote on building Shopify apps with .NET and C#. It's long overdue, the book still uses Shopify's deprecated rest API and some methods that aren't supported anymore, but I've been holding off on an update until I could rewrite it with the new fluent query builders in ShopifySharp.
Outside of my OSS stuff, I'm continuing working on my SaaS app, Stages (https://getstages.com) [Ā¹], which has been paying my mortgage and bills. Customers have been asking for lots of features lately and I'm anxious to get a particular one finished (filtering orders and events before they come in and are saved to the app) soon. It's my biggest source of churn right now.
[Ā¹] Elevator pitch: the app is like a pizza tracker for your orders that have a custom or long, drawn out production process. Your staff and customers can see exactly where an order is in the process without calling or emailing you. Shopify only for now but one of main dev goals is to move beyond Shopify.
After around 15 years working with clients and helping them wrangle their WordPress sites, I stopped working with WordPress as a primary platform for building sites.
A while back I've switched to a more modern stack and have fully abandoned WordPress.
Having that background, however, I've come to know (way too well) many of the frustrations and security problems with the WordPress ecosystem. As a result, I started a service to help business owners break free from WordPress on to a more modern Next.js-powered stack that's faster, lighter weight, and easier for them to manage.
Been a side project for a few months, as I wasn't enjoying the official client, and wanted something that fit my particular tastes (scroll position permanence, greater emphasis on hashtags, support for Shortcuts, and a more iOS-native look and feel).
Launched 3 weeks today, and already nearing 100 subscribers (nearly all annual, but month-to-month also available). Been very fun seeing users start using the app each and every day!
Orchestera (https://orchestera.com/) - Fully managed Apache Spark clusters in your own AWS account with no additonal compute markups, unlike EMR and Databricks.
Currently implemented the following:
- Automated scale in / scale out of nodes for Spark executors and drivers via Karpenter
- Jupyter notebook integration that works as a Spark driver for quick iteration and prototyping
- A simple JSON based IAM permissions managementent via AWS Parameter Store
Work-in-progress this month:
- Jupyterhub based Spark notebook provisioning
- Spark History Server
- Spark History Server MCP support with chat interface to support Spark pipeline debugging and diagnostics
It's yet another video game backlog tracking service but I'm building this one to automate as much as I can about the actual game logging process. So for example, I'm auto-forwarding all my Nintendo and PlayStation purchase emails to a custom inbox. That email gets parsed, the game(s) and date(s) are extracted, and I get a new queue item I can approve or deny easily on my phone. It also has a documented CRUD API for easy integration for other services (like Zapier).
Yes, it also has a chatbot... I've been toying with a natural language interface for quick actions like "just beat TOTK" to mark Zelda: Tears of the Kingdom as "beaten". It's a bring-your-own-Gemini-key approach... So far, its working pretty well for me. It also supports basic questions about your game library and history that would be tricky to represent without a lot of filtering options. Like for example, "How many Switch games did I beat between March and July of 2024?". Fun stuff like that.
Tech stack is Django/HTMX/Alpine/DaisyUI/Postgres/self-hosted.
If you decide to try it out, I'd love your feedback! There's a quick in-product feedback widget on the bottom-left which sends me an email :)
While it's true that the agentic coding assistant space is crowded (Claude Code, Aider, Opencode, Codex, etc.), we needed something supporting both local and cloud models that we could easily modify/extend for custom workflows.
Being able to access the agent through both a terminal and a Python API/REPL has come in handy.
Recent releases includes custom tools, agent skills, and built-in support for Ralph Wiggum loops.
I'm building Ditto ā it clones websites with 100% visual accuracy and outputs a proper React app with named components and preserved structure.
The problem: you find a design you love, want to use it as a starting point, and your options are either manually recreating it or using a tool that spits out a tangled mess of divs and inline styles. CatchDitto gives you an actual codebase ā clean component hierarchy, sensible naming, structure you can extend without wanting to rewrite everything first.
I'm still iterating, would love to hear what others think.
Iām working on an open source CLI that experiments with governance at inference time for autonomous systems.
The idea is to let multiple agents propose, critique, and stake on decisions before a single action is taken, rather than letting one model silently decide. Itās model-agnostic and runs locally, with no blockchain or financial layer involved.
Iām mostly exploring whether adding explicit disagreement and cost at decision time actually improves outcomes in high-stakes or automated workflows.
It's a bit like Reddit but focused on learning. (Doom learning instead of doom scrolling)
You 1) upload a source 2) direct the kind of questions you want to be asked 3) start answering (and if you get the answers wrong, you can discuss the problem with "AI").
You can read other people's sources, questions, answers and their discussions with AI too.
And if you're learning the same thing as other people, you can join communities to share sources/questions.
It's still very early on, so I'm very interested in any feedback.
Iām building PointWiseSystem, a browser-based habit and responsibility system I originally built for my own family.
It uses a simple points model instead of streaks or financial-style tracking to make expectations visible, progress clear, and follow-through easier.
In real use itās solving three main problems:
- As a Family Chore Chart ā a digital chore system that actually gets kids engaged with responsibilities using points and rewards.
- As a Personal Habit Tracker ā a way for individuals to organize routines, add notes, and earn points toward meaningful self-defined rewards.
- As Complete Homeschool Management ā tracking assignments, logging progress by subject, and generating reports and transcripts for multiple students.
Itās entirely web-based (no app download) and works on phones, tablets, and desktops. Iām actively iterating on it based on real use, and itās been most useful in situations where simpler systems actually get used instead of abandoned.
I was teaching coding to my 10yr old and we were talking about creative projects on the internet. That led to discussing the Million Dollar Homepage and why something that simple worked.
He asked: could we build something similar today?
That curiosity turned into moltbillboard.com ā a simple public billboard, but born in the era of AI agents (inspired by the recent OpenClaw craze).
Itās just an experiment..
My previous games have all been exclusively in English, but this one also has Spanish, French, German, Dutch and Swedish. It's a take on the classic word ladder game, with golf scoring mechanics.
Still needs a bit of fine-tuning for the word lists and puzzle generation, but I think it's already pretty playable. :)
Fully off-grid using solar, batteries and Starlink for uplink. Focusing on AI inference at the beginning. Currently building our first prototype and testing cooling solutions.
Forge is an orchestration layer that sits between AI coding tools and your codebase. It's a single Rust binary (~3 MB, zero runtime deps) that runs as an MCP server over stdio. Any MCP-compatible AI tool can call it.
A document RAG API based on multimodal embeddings that's intended for data extraction. If your document workflow involves search and you're looking for ways to cut down on VLM (OCR) costs, Ragextract provides a simpler alternative (less bells & whistles) which makes sense for startups, SMEs and freelancers.
As someone who works on AI document workflows, I use Ragextract myself to reliably execute for various clients in finance, insurance and proptech. I'm currently working on marketing/messaging for the service and could do with more feedback and use-cases.
Have a new or existing project which could use something like Ragextract? Email me and if there's a fit happy to provide a demo or free subscription.
Working on reproducible test runs to catch quality issues from LLM providers.
My main goal is not just a "the model made code, yay!" setup, but verifiable outputs that can show degradation as percentages.
i.e. have the model make something like a connect 4 engine, and then run it through a lot of tests to see how "valid" it's solution is. Then score that solution as NN/100% accurate. Then do many runs of the same test at a fixed interval.
I have ~10 tests like this so far, working on more.
I've been working on this project, which lets you create interactive Valentineās Day invitations for your special someone. You can pick from a set of templates, add your own message or photo, and share it easily.
Currently, adding CMS feature so that user can edit their info right in the website and get the link instead of them hosting themself or editing the code.
An all-in-one operations workspace that starts with forms but doesnāt stop there.
teams (especially HR and ops in small/medium companies) need to launch and operate fast, but the moment data comes in, everything falls apart into spreadsheets, emails, and half-used tools. the real work starts after collecting data.
What weāre building:
Form & workflow engine, and backoffice layer on top of submissions: tasks, assignments, reminders, budgets, client/contact directories, inventories, meetings, internal knowledge base.
Itās less āTypeform competitorā and more āwhat happens after the formā, for HR teams, marketing teams, and SMEs that want one calm, predictable system instead of a tool stack.
I'm a solo dev founder working on Potniq (https://potniq.com) - a business travel tool that tells you exactly when to leave based on your entire itinerary.
I used to work in devrel, and traveled a lot for events, and I always struggled skipping things like workouts, looking at the time on the last day of a conference trying to check whether it's time to leave yet - so this gives me the opportunity to build a tool I would have loved to use.
Currently I'm working on a LLM-powered booking email parser, that ingests forwarded booking confirmations and adds flights, hotels, etc. to your itinerary.
I am getting the AI Agents to build an expense tracker Telegram. I would like to have one myself and among my family members since we are heavy Telegram users. I am also using this as a way to learn more about the AI Agents (what they are good at, their limitations, etc) with (hopefully) proper guardrails, guidelines, checks, etc.
As you may see from the git history and "contributors", it's mostly Claude and AMP making the changes.
I am not entirely sold on these agents and not particularly excited by these. But I also feel that I can't afford to sit out this transition so here I am...
Iām building Historic, a private AI video journal for founders.
You record short morning, evening, or ad hoc sessions, and it transcribes and indexes them into a searchable archive of your thinking. It uses simple Apple Fitnessāstyle rings to encourage consistency, plus monthly insight reports and suggested ābuild in publicā posts.
I built it because notes apps werenāt capturing my thinking in full fidelity. Using Reflect I averaged ~65k words per year. With Historic I logged ~85k words in one month.
Your thoughts are already your most valuable asset. Historic just makes them accessible.
I'm working on Lightningbeam (https://lightningbeam.org), an integrated multimedia editor. It's inspired mainly by Macromedia Flash, Apple GarageBand, and Kdenlive. It combines animation, audio and video editing into a single timeline. It's cross-platform, running natively on Linux, macOS and Windows.
I'm currently rewriting the UI in Rust - previously it had a Rust backend and a JS frontend using Tauri, but I ran into bandwidth limitations which prevented it from being really usable as a video editor. It's currently in early alpha.
Keep working on a GUI calendar for Linux which would CLI users happy to use https://semana.alexmarkov.xyz/. Just recently I've shaped the architecture a bit.
Finding work after a corporate restructure. Also migrating my workloads from VMs and strewn-about containers onto a Talos K8s node, so I can break the cycle of bespoke builds at home and get back to enjoying projects.
Speaking of projects, Iām roughing out a method of pulling cost data for common services (compute, storage, databases, etc) across the three major cloud providers and making recommendations as to where to put things for optimal cost; a key component of a āuniversal cloudā idea Iāve been kicking around since 2020 or so, where the base cloud services are abstracted away into commodities rather than bespoke products or locked-in vendors. The goal is to basically have something like Terraform that will transpose its code to the destination cloud chosen by the cost analyzer at execution, and eventually auto-migrate load as prices or needs change (e.g., a client churning early and shifting that reserved instance to another customer for a higher margin).
Write once, and trust the pricing model to deploy it where it makes the most fiscal sense. No more learning Azure/GCP/AWS for bog-standard workloads anymore.
Delving deep into novel ways to extend Excel and make it more accessible. Perhaps different approach to copilot in that AI is only used during authoring, the yielded output being a standalone artifact.
It embeds Luau which tames the very old school C SDK. This means that the same code can run as native add-ins on Windows (XLL) and the more modern-but-far-slower web engine, thanks to WASM. Luau is safe and fast.
The exact same bytecode runs in both styles of add-in. You get the performance of native with no extra work. Many approaches for writing custom functions are unacceptably slow, particularly when their inputs come from fast moving realtime data feeds.
I know Luau is perhaps a left-field choice. However, coupled with a coding assistant and bringing that lightweight conversational dev experience right into Excel (xllify Assistant is an add-in itself) this is perhaps less of a barrier.
It's still in beta but I repackaged Descent Raytracer (a remaster of Descent (1995) made by students at Breda University) to be launchable on macs with Apple Silicon (ray tracing reqs M3+).
Iāve been working on something we call the Functional Universe (FU), a modeling framework and experimental codebase that treats systems as sequences of irreversible functional transitions, rather than objects evolving against a global clock.
It started as a computational experiment, but itās been interesting how naturally it lines up with ideas from QM (aggregation vs collapse), relativity (proper time), and distributed systems (event-driven causality). Still very much a work in progress, but already useful as a way to think clearly about time, causality, and scheduling in real systems.
Over the last few weeks Iāve been building Pointless (https://pointless.cards), a Planning Poker webapp thatās both frictionless (no sign up) and actually fun!
Iām trying to embody the experience of a JackBox game into a Scrum ceremony that should be lightweight but is often painful and tedious. Iāve also gotten to learn a lot about Cloudflare Durable Objects building this and have been delighted with how easy they (and PartyKit) make building multiplayer apps like this.
Itās completely free (I plan to keep it that way) and full of easter eggs and delightful jokes at the expense of Jira and modern software development, of course. If your team is following Scrum and could use a bit more joy in the process you should check it out!
An alternative to tools lik sst.dev or serverless framework, or a PaaS services like Render.com or Flightcontrol.
Deploys to user's own AWS. IaC-first. Has a PaaS-like console UI.
The best features: auto-generates IaC config by scanning your code. Has built-in EC2 runner which is 2-6x faster than AWS CodeBuild.
We've now also implemented dev mode, which is similar to SST. It deploys parts of the stacks that can't be locally emulated (lambda functions, cognito, etc.) with fast re-deploy, and emulates everything else (containers, SQL databases, Redis, DynamoDb, etc.) locally. This means testing/developing is pretty much free, and you have the fastest feedback loops possible.
Whole Stacktape, and dev mode in particular is also very optimized for coding agents with `--agent` flag.
To try it, run `npx stacktape init`
EDIT: Changed the link to github. Stacktape core is now open-source.
Previously I built a jar/docker and deployed to a common server. Fine.
Can this service deploy this to AWS free tier? Will it "know" how to avoid any paid services? (I don't necessarily need a docker or even permanent storage yet)
EDIT: Also - charging a % of AWS bill is pretty wild...
The cheapest way to deploy a container accessible over HTTP is to use web-service resource (which uses AWS ECS loadbalanced with HTTP-Api-Gateway, which is pay-per-use) and use EC2 launch type (cheapest instances are only a few $). Not sure if it's still under AWS free tier, but definitely not expensive.
Regarding charing % of AWS bill - yes, we're changing that soon. It's going to be flat fee + 10% of AWS bill.
Our free tier covers 90% of vibecoder, freelancer and side-project use-cases though. So probably nothing to worry about unless you're a 2+ person business. And at that point, it's still far less expensive than having a DevOps person or learning all of the 150,000 AWS loopholes yourself.
This isn't a serious project by any means, but rather a prototype. Also, I really got carried away using Claude Code, although my initial goal was simply to glue a quick proof-of-concept and see how it could look like.
Dimensionally accurate AI 3D modelling. My grandpa has a 3D printer but struggles to use any complex tools. So I am working on this chat interface to allow him to do some simple models.
So far he has triggered more than 150 generations. Itās getting better every model cycle and gives me something I enjoy working on.
Building better quality cadastral data on all of Italy for a client, pretty fun postgis work. Fuzzy string matching of government records, OSM, proprietary data and aerial remote sensing data ran through an ML pipeline.
Working on migration from Modal to a single nvidia jetson, to do low-cost monitoring of toxic emissions at the local tata steel plant. Ran this pro bono for the last 2 years, the fun is in getting this as cheap as possible but still with good accuracy
Building a SSTV ios app - you can encode images in sound and transmit these over (ham) radio. The ISS regularly broadcasts these too. And building a multi-user IRC-like chatroom over audio. Hook up your mac or ipad to a voice radio channel, and chat over very slow (31 baud) but very resilient links.
NuGet.org doesn't distinguish between a hobby project and a professionally maintained library with real support. pkgstore is a curated directory and marketplace where publishers can sell NuGet packages directly, with full dotnet push/restore support, Stripe payments, and automated access control.
In open beta now, onboarding publishers. Would love feedback.
Iāve been suffering from migraines for the past few years and wanted a dead simple way to log when they happen, as well as any other contributing factors I could think of. Inspired by the simplicity of spreadsheets, I built a grid of events, and as you tap on cells, you log ādotsā. Those dots, over time, reveal patterns.
Iāve already identified several contributing factors to my migraine triggers using it. Itās been so genuinely useful I wanted to share it with others hoping they might also benefit.
The next big release is coming out later this week which includes visualizations, charts, and on-device analysis of your journal to provide insights.
I am building QuietReads (quietreads.com) - a single-player book tracking app with an AI assistant.
I got tired of the gamification and social elements of Goodreads, StoryGraph and others. I don't care too much about reviews, but do care about engaging deeply with what I am reading.
Lot's to do still:
- Refining the experimental MCP integration so I can bring my bookshelf into my AI assistants
- OCR to build notes from screenshots
- Voice notes
I'm working on a search engine for clinical trials around the world.
I was frustrated by the process of searching for clinical trial info using the clunky and slow registry websites. So I aggregated all trials around the world and made the search faster. Additional features:
- You can watch a trial and get email updates
- Sometimes a trial is done and a paper published, but no updates to the official page. I try to find these papers and link them
- I try to link trials with the same drug together, showing the drug going through different phases
I continue with my suite of mobile apps for parents:
* https://screenspy.app - observe what youd child is doing on desktop PC. Roblox or homework?
* https://weblock.online - a VERY restricted, whitelist-first mobile browser for kids, use it instead of Safari. I want to feel calm when my children browse the web.
Posturr is a macOS app that blurs your screen when you slouch. Iāve always had bad posture at my desk, so I wanted to figure out a way to check myself. This idea is not radically new, but the methods by which Posturr reminds, e.g. blurring screen, colored border, is unique and effective.
I'm still plugging away on my PostScript interpreter. Right now I'm working on the clip and eoclip operators which has turned out to be much more complex than I expected. Mostly because I am not using any 3rd party libraries nor any AI generated code.
On the house front I'm just about to install an IKEA kitchen.
I've been working on a security model and architecture to make a hardened rewrite of OpenClaw. I've got a first pass of prompt injection and secret exfiltration protection and an agentd that gives network vm/sandbox access, reads the accessibility tree and can take screenshots of apps or regions of the desktop. I also have full policy control in place with OPA so you can manage everything the agent can do in one place.
The goal is a milspec, zero-trust autonomous agent that can be completely locked down. I'm also tying the agent's heartbeat into activitywatch so it can be a good personal assistant and do stuff for you pre-emptively based on your stated goals and session activity.
Semi-academic attempt to build semantic-level standard system for data type classification. Useful for metadata semantics data lakes / warehouses beyond basic physical level like text/number, with assumption that it may be useful for AI-targeted metadata, your text to sql cases. https://github.com/jaakla/semantic-field-types
I find quantum mechanics fascinating and wanted a better way to play with it.
Linear types prevent copying qubits, effects track what's quantum vs pure. The type system catches mistakes that would otherwise blow up at runtime.
Runs on a local simulator (with various qubit types modelled) or IBM hardware (sort of). Still a research and learning language for me - I break things regularly.
If any real quantum physicists are lurking, Id love to hear what Ive got wrong!
Working on https://dataraven.io/ ā a low-cost, cloud-native data movement platform focused on object storage.
RClone is doing the heavy lifting (amazing project). I'm wrapping it with the operational features clients have asked me for over the years:
- Team workspaces with role-based access control
- Notifications ā alerts on transfer failure or resource changes via Slack, Teams, Discord, etc.
- Centralized log storage
- Vault integrations ā connect 1Password, Doppler, or Infisical for zero-knowledge credential handling
- 10 Gbps connected infrastructure (Pro tier) for large transfers
I want to create a tool that would automatically block the stealers from stealing your previous credentials or crypto wallets. I had this idea after the Shai-Hulud attack
It's an experimental side project, but so far it looks very promising.
Working on a platform where you describe a story concept and it becomes a real, illustrated picture book - professionally printed and shipped to your door.
The key difference from "personalized" book companies: this isn't template stories with a name swapped in. You bring an idea - maybe a book about a kid with a cochlear implant going to their first day of school, or a bilingual German-Turkish story about visiting grandma's village - and it generates a complete original narrative with consistent illustrations throughout.
You can upload reference photos so characters actually look like your child. Supports 30+ languages including bilingual editions on the same page.
Currently refining the showcase features and adding RTL language support.
I too was thinking about something like this a few months ago. There were couple of reasons I didn't pursue the idea. One, the image generation AI wasn't reliable enough. Like, I couldn't get it to generate 2 images where the characters looked consistent, let alone a book worth of images. Two, the margins were quite small, so didn't seem like a viable business.
Wondering if you've thought about such things and your perspective.
Character consistency was the hardest problem, and honestly what took the longest to get right. We use reference images as style anchors, run multiple generation passes, and have an LLM "critic" that checks for visual inconsistencies and triggers regeneration when needed. It's not perfect but it's gotten to the point where parents are happy with the results.
What do you mean by RTL because all I can come up with is Verilog or VHDL and I'm certain that's not your meaning. I'll try it out. I have a children's book story I've been trying to image generate for 3 years now and it's not yet worked out. I think the primary reason it fails is that the scenery I request is lifelike yet extremely rare to actually see, although, I did see it, and that's what inspires the story.
RTL = Right-to-Left languages - Arabic, Hebrew, Farsi, Urdu. The text rendering and page layout needs to flip for these, and it gets especially tricky with bilingual books where one language is RTL and the other is LTR.
What's the scenery? Happy to try it on our system if you want to share.
The story synopsis next to the preview gives you the full narrative arc before you commit. But fair point on wanting to see more.
You can edit or regenerate pages if something isn't working - it's iterative, not one-shot. Happy to help you try it out without payment - drop me an email.
preditor: A simple image viewer that shows each image in the center of the screen in a window sized for that image with some basic editing functions built in.
https://github.com/rabfulton/preditor
Iāve just published the first public release of a new open source project Shovel.js, replacing tools like Express, Fastify, Next.js, Vite. Itās a full-stack/meta server framework which implements the full Service Worker specification but in Node, Bun, Cloudflare. It leans into using web standards to do things like accessing the filesystem, reading cookies, create client-side bundles rather than inventing new APIs. You can read about the process of making Shovel with AI in the introductory blog post.
The biggest problem is internal knowledge and external knowledge systems are completely different. One reason internal knowledge is different it is very specific business context and/or it's value prop for the business that allows charging clients for access.
To bridge this gap, the best approach is to train agents to your use case. Agents need to be students -> interns -> supervised -> independent before they can be useeful for your business.
I just proved that constraint solving problems can be encoded as p-adic linear regression problems[+], and that therefore we can use machine learning optimisation techniques to get exact answers.
So of course no journal or conference is in the least bit interested, and I'm now reformatting it for another obscure low-tier journal that no-one will ever read.
Otherwise:
- automating the translation of a Byzantine Greek work that has never been translated into English before. https://stephanos.symmachus.org
- also preparing evidence for a case against the university I sometimes work for.
Offline first, no tracking PWA for intermittent fasting and mindful eating. It helped me lose another 3 kg in January. Spiked a native iOS version, but I really like the simplicity of just the PWA. Not sure what's next!
Having done a lot of back and forth with LLMs and at the end throwing away learnings from a conversation felt so wasteful - reposit allows you to /share a summary of the valuable learning from your LLM chat for others to discover.
At the beginning of researching a problem, your agent can search reposit just like Context7 for docs. This way, even if you opt out of sharing your data with your LLM provider (as it's all or nothing), you can choose to publicise a solution to your problem with very little effort.
I'm working on extracting valuable learnings from open-source community projects as a starting point now (with attribution), as it probably needs a larger database to be valuable for users to install and use.
You can also self-host it and share privately within the company.
- Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains)
- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference
- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more
It's getting close. I'll do a show HN on it sometime soon.
This is fun! I put my (slightly oddly setup) system into it but I couldn't reconfigure which set of speakers were connected to which amp, or reorder the signal chain at all. Is this a planned feature? E.g. I have an integrated all-in-one amp that drives my main speakers but I tap off the pre-amp output into a secondary integrated amp that drives two secondary sets of speakers but your app assumed that my second amp was driving all six speakers and so spat out a warning about power levels...
I built a mobile app for golfers who don't like using their phones while they play. Take a picture of your scorecard after the round and it reads/saves the scores and stats (and allows you to post to the USGA if you keep your handicap).
I'm a self-taught coder who first built this 7(!) years ago but couldn't figure out the OCR part. Started again 9 months ago on Replit (starting with Agent 2 which was okay, then eventually starting to absolutely crank with Agent 3) and it works really well now.
Would love feedback from any golfers! golfrise.com
I'm working on ArkWatch (https://watch.arkforge.fr) - a monitoring API that you can use with just curl, no signup required.
The insight: most solo founders need basic "alert me when this changes" monitoring, but existing tools force you through signup flows, credit cards, dashboards you'll never use. So I made it dead simple:
That's it. It watches the URL and emails you when content changes. Free tier = 10 checks/day, which is enough for most side projects.
I built this because I kept forgetting to monitor my own stuff. Now it's live and I'm trying to get my first 5 beta testers. The challenge is marketing - I'm a developer, not a growth hacker. Learning as I go!
What's been your biggest challenge with your current project?
To show newbies how to use vim. Currently its not complete and has major issues. So if you want to try give it a go, but please hold your judgement as not all shortcuts have been added.
We ran into the annoying Envoy 503 bug in our prod and needed some quick tools to help figure out what was going on with TCP connections and HTTP requests.
This tool tracks TCP FIN packet timing to see how upstream connections are closing and how keep-alives behave. It helped me spot when connections were closing too early or timing out, which was causing those 503 errors.
A fast, minimal httpbin clone written in Rust. Itās way faster(20x throughput) than the usual httpbin and useful for testing HTTP clients and debugging requests without extra noise.
These arenāt polished, just some stuff I needed to iron out the issue.
I'm working on a macOS app that identifies music playing around you, constantly. You can scrobble them to Last.fm, ListenBrainz, LB-compatible sites, a Mastodon account, local Shortcuts workflows, and/or or local files. It also support Apple Music and Deezer.
I built it because most scrobblers only keep track of Apple Music or Spotify plays, but I have streaming stations on all day long, or the radio is on, and those never make it into my playing charts or recommendations etc.
Early days, more to come, public beta is ongoing, and I am looking for testers :)
I built meepr recently. It's basically twitter v1, but the hashtag system is gated, it builds a knowledge base of what you talk about and how deeply, and then enables you to post into/create hashtags, think of twitter meets reddit meets quora? Feel free to follow me and share with your friends. No recommendations, no algorithmic timeline, no ads etc. Just regular old micro-blogging with a small twist. https://meepr.co/je
The other thing I built but am less interested in personally just through should exist, is something like MoltBook but for more formal topics like the sciences. -> https://ideas.gd/
DarkRadiant is open source, cross platform level editor for The Dark Mod and other idTech4 games like Doom 3, Quake 4 and Prey. It is a lot of fun to add features that make level designers more productive. I would like to invite anyone that is curious about wxWidgets, CSG and game dev to join us.
If you are a designer, we could definitely use a new icon set.
Itās a special UIKit map package, designed to be integrated into SwiftUI, as map support is a big SwiftUI Achilles heel.
I have integrated it into another package (a SwiftUI admin tool, that isnāt public), and it works exactly as I planned.
I often do this kind of thing. If I can break some module out of my work, and publish it, I spend the extra time, polishing and documenting it. No one else really cares, but it forces me to do a really good job, so I get an extremely high-Quality component, that I donāt have to worry about, later.
Interesting! I've recently plumped for UIKit (with bits of SwiftUI dropped in) for a new mapping app because, as you say, SwiftUI map support is virtually non-existent. Have you thought about adding Maplibre support as an alternative to MapKit?
I try to use MapKit, when possible, as it is unencumbered by licensing and support issues (and works pretty well), but I have considered MapBox. Itās commercial, but pretty straightforward, with licensing and support. I have heard good things about it.
I donāt really know about Maplibre (but Iāll check it out).
Had a friend create an app, based on Google Maps (if you remember, in Ye Days of Yore, GM was the mapping engine for iOS), but Google did the licensing rug-pull thing, and he had to do an emergency open-heart surgery to his app.
That was a sobering lesson about relying on third-party dependencies.
[EDIT] Looking at your app, Iāll not be surprised, if youāre familiar with my friendās app: EasyRoute
New things not making money yet
https://admakeai.com - AI ads generator for facebook ads. Made mostly so I have a easy way to prompt for stuff and keep track of good AI ad prompts. Have been using it to make static image ads for BestPhoto and actually have over 40 conversions at $~45/conv. Pretty good considering my previous attempts with my own handmade ads using canva was like $80-100/conv. but most of the time FB wouldn't even spend anything from my budget before
Fun stuff/for myself:
https://xhdr.org/ - Made like a few months back when twitter was allowing HDR images in your profile pictures, they patched it like a week later, but was fun while it lasted. Still works for facebook, keeping it up for FB video ads, I've noticed people abusing this a lot when scrolling on FB recently searching for good ads, so I'm guessing it works? Good way to get attention of people on iphone quick
https://framecall.com - Saw people making cool AI motion videos using the claude code skill with remotion, so packaged it into an actual web app you can use as a chat instead of through terminal. Harder than expected to get all the tool calling(and auto continue) stuff to work, similar to how claude code works
TranslateVoice(name TBD) - An iphone voice translate app where you tap microphone button and it uses 4o realtime to translate between you and someone else. This was originally one of the biggest thing I was hyped about as a usecase when 4o released but when I tried it on their app, it just didn't do prompt following well at all it would randomly try to communicate with the user instead of strictly translating, just randomly cutting off someone before they finish speaking etc. Currently have 3 modes that work, that if no one else uses I will be using:
1. Interpreter mode: Basically User 1 speaks to phone in their language, phone talks to user 2 in their language, user 2 replies to phone in their language, phone replies to user 1 in their language etc. Just pure translation, with chat history transcribed in each other's language
2. "Friend mode": You tell it a general goal, "I want to get immigration documents, I need to know the requirements" it then basically acts as if its a friend you called to help with translation and gathers everything while talking back and forth with User 2 and then at the end goes back to user 1 with all the info.
3. Stealth mode: Airpods in, it will transcribe and translate everything being spoken and tell you what to say based on initial goal or you can also write extra instructions in the chat. This is currently the only non-working/buggy one I'm trying to figure out before releasing this, since both will be speaking in same language its hard for model to know who is user 1 and who is user 2 automatically.
First time I'm creating an Iphone app fully vibecoded(react native so I understand whats going on frontend wise at least cause of react). Not looking forward to the app store review process. And I know this is likely something someone already made but its probably paid and I have like $25k in Azure credits I can burn anyways.
Cascade Puzzle, a daily puzzle game inspired by Panel de Pon / Tetris Attack. Swap blocks horizontally to match 3+, trigger chain reactions, clear the board in limited moves.
I originally started this years ago and abandoned it because puzzle generation was hard and I didn't have the proper time to finish it. Picked it back up recently with Claude Code and finally cracked it, the generator uses backward construction (starts solved, reverses moves) so every puzzle is guaranteed solvable.
3 daily puzzles (Easy/Medium/Hard), shareable results like Wordle, no account needed.
I'm making a suite of simple Windows tray apps that do just one thing. They often have existing equivalents but I think my version is better and/or simpler ;-) All work starting with Win7.
The first three are:
- miniWake: keeps the computer awake
Alternatives: Powertools; USB mouse jigglers
Features: installs without admin rights; triggers invisible mouse events; turns off at LOCK, turns back on at LOCKOFF (saves battery); manual turn off or on via double-click on the icon
- miniRec: records system audio + microphone to mp3/wav
Alternatives: various utilities like Voicemeter, AudioRouter, or some DAWs
Features: does not require any special driver; installs without admin rights; light on resources; "invisible" to third parties (video meetings); auto turn off after 5 minutes of silence (configurable)
- miniCron: system scheduler as a service
Alternatives: NSSM - the Non-Sucking Service Manager; Splinterware
Features: launches any program at any given time (cron like but without cron syntax); kills the current task when the service is stopped; reads and logs stdin/stderr; very light on ressources and very simple
Ah yes, it's a good idea to record microphone and system audio to different files but I ruled against it for simplicity's sake. I wonder how you deal with offset, esp. when the mic comes from a Bluetooth headset? I added an offset option in the config file as this can be up to 2000 ms (2s) in my tests! Also, a console app may frighten the non-technical, casual user?
I build an AI automation that finds cool things to do in my city, which is stockholm and updates the website every night along with updating the website with the events it also automatically publishes top 5 events to instagram. I use gemini nano banana model to create event posters for instagram
Built ShelfSwap (https://shelfswap.io). I enjoy reading, but books are getting expensive, and many of us already have shelves of good books weāre done with. This is a simple platform to swap physical books and connect with other readers.
I used this as a real end-to-end project to sharpen my backend skills in Go (API design, data modeling, deployment), while also experimenting with AI-assisted development. Itās live, and Iāve already made a few organic connections through it.
Would be cool to auto-sync with existing book management tools like clz.com/books. Also, are swaps mutual exchanges, or are members giving books away with nothing in return?
With LLMs, the cost structure is credits/tokens all the way down. This month, I built a tool to help you price your service credits or plans at https://aitokenpricing.com.
I also did a write up of PRDs and using Railway to build apps on my blog at https://aftercompsci.com.
I've been working through the pwn.college curriculum, as well as building https://stoacentral.com. It's meant to be a place to chill, discuss philosophy (Stoicism), and improve yourself. I built it after becoming annoyed with Facebook groups, really.
If you're interested in Stoicism, feel free to join and start some discussions.
I am working on a e-commerce and pos solution. More like shopify/saleor/woocommerce etc. with ready to start for small businesses selling physical and online and in-store products and services.
The platform itself is built on elysiajs/bun and tanstack and is completely hosted in EU and the payment processor is a EU based entity and we have an ISV partnership.
I am trying to make a cheaper, straightforward easier to use observability platform with a good core offering without going overboard on features. Based in Europe.
It automates installing and managing Incus, Caddy, and SSHPiper, provides a TUI for container lifecycle and quick actions, a web admin (built/compiled on the container) for toggling and updating AI coding tools (Shelley, Claude Code, OpenCode, etc.), and a background sync daemon that keeps Caddy routes and container metadata in sync.
Each container exposes coding tool web UIs on isolated ports and supports direct SSH/VS Code Remote access, so you can run multiple independent coding agents against real project files without exposing your local machine.
The project emphasizes simplicity and recoverability for running agents locally: containers are persistent, optionally routed via reverse proxy with basic auth, and tracked in an SQLite DB so setups auto-heal after restarts. Itās written in Go, includes an install script for one-line deployment, targets modest VPS specs (4ā8GB RAM recommended), and bundles helpers for DNS and provider automation.
Ideal if you want a lightweight, opinionated way to host multiple isolated AI dev environments on your own server instead of relying on hosted agent platforms.
Since we recently moved out of the city and into the mountains of Switzerland, I had a niche problem... agreeing with my buddies which is the best ski field to meet at when we all live in different towns. So I made a little web app to help:
This was a fun little project I did over the Christmas holidays but only finished off recently. Basically I precalculated the public transport time between the most populated towns in Switzerland to every ski field (about 350 of them!) and then built a little web app around it using Django.
You can choose to prioritise shortest (lowest time overall) versus fairest (smallest variance in group members).
Totally free to use. Next steps are to integrate it with live snow conditions/open lifts...
Claude did help a lot with the FE part. The biggest part was actually finding the best public transport stop for each ski field - that was a very manual process trawling through skimap.org images and Anreise info on ski resort websites.
It analyzes thousands of professional critic reviews to find the best of the best.
I started building this because I adore how metacritic analyzes professional movie/game/tv show reviews and calculates a meta score for each title. In my experience itās the best way to discover new things to watch or play, and Iāve often wished something like this would exist for when I want to buy a product.
This year, I decided to start building it myself and Criticaster is the result.
For a given product category we collect all professional reviews of a given product, analyze each to assign them a score and then calculate an average critic score.
The goal is to become the most trustworthy source to make product decisions.
I built https://bookcall.io. out of the annoyance existing scheduling platforms have. It's nieched towards solopreneurs, coaches, consultants, and similar that just need it to work and help them sell themselves. Also includes video calls. Would love to have feedback/pushback on the idea. But I happily use it for a while now.
I finally got to rework my html form forwarder[1]. I realized how cheap SES is and thought I might as well make the service free.
I hope open sourcing it could be a way for me to get some mentorship from more experienced devs as well. Unfortunately, my work doesn't really do code reviews so I feel like I am not improving much on that front.
Just tried out Opus 4.6 to make a ground-up new version of a perennial side project: static site podcast player.
For this one I focused on loading speed and reducing interaction with repo. So it processes the images (converting to webp) and loads the feed list from a Gist. Also used the "frontend-design" skill. From brief to ready-to-use took about a couple hours.
Klondike solitaire game using Godot. The goal is to better understand Godot's inner workings, and not using any LLMs... outside of whatever Google searches automatically popup when I have questions.
Secondarily, decompiling the DuckTails Gameboy ROM with PHP... then seeing about using PHP to create a GameBoy game. For no reason than to see if it can be done.
I developed my first macOS app, an API client built purely with SwiftUI/AppKit. It has themes like Nord, Monokai and 8 others. Been using it for my own personal use for the past 6 months.
I have been working on chemistry arena designed to benchmark the current SoTA LLM's on drug discovery tasks. My plan was to then focus on getting this annotated to sell this data for post training of scientific reasoning models. https://github.com/deepakorani/chemistry-arena.
Also trying to find a co-founder who I can work on projects and solve problems faster to be honest.
A platform to efficiently work with any data right in the browser. Like interactively visualizing millions or rows, and at the same time augmenting the data with domain-specific capabilities. For instance, the cheminformatics plugin automatically recognizes molecules and provides proper rendering, substructure search etc. Sort of a Swiss Army knife for scientific data.
Not really a new idea, been working on it for many years already :)
Hi,
Iām splitting my time between multi-cloud governance and optimizing my "vibe coding" workflow:
Kexa (https://kexa.io)
An open-source multi-cloud governance framework powered by a YAML rule engine. We just reached a milestone by adding Database (DB) support.
The goal is to allow developers to audit configuration and compliance directly within DB instances, alongside standard cloud resources (AWS, GCP, Azure, K8s). Weāre focusing on keeping the YAML rules as agnostic as possible so the same logic can apply across different environments without rewriting everything.
rtk (https://github.com/rtk-ai/rtk)
This is a "scratching my own itch" project born from using Claude-code. While vibe coding, I got frustrated watching the agent spam ls -al or cat repeatedly just to "orient" itself.
It creates two main issues:
The Token Tax: It burns through tokens for info the agent already has.
Context Pollution: The context window fills up with redundant noise.
rtk acts as a CLI wrapper/filter to make LLM interactions more signal-to-noise efficient. It silences or summarizes redundant outputs so the agent only receives the necessary "delta." Itās a simple attempt to keep the context clean and make sessions last longer before the agent loses the plot.
BrowserBox embedding API plus a bunch of other side projects. BrowserBox is a remote isolated browser with a variety of DLP, NIST 800-53 controls and FIPS 140-3 encryption at rest. It can function as a fully automated embeddable browserview for AI workflows, isolated sandboxes, generic whitelabeled RBI and multiple other use cases. It's a heavy target of abuse by non state actors in sanctioned countries so I had to add ID verification to get a trial key.
Working on either a self hosted, or self "provisioned" document extraction platform. Trying to make it as flexible as possible, so businesses
I worked with manufacturing companies, and the amount of manual document extraction and manipulation, particularly from accounting documents, was always a large burden.
The goal is upload a document ā extract structured fields via LLM ā generate new documents from templates. Has a dashboard, with an API, along with a webhook, very much a WIP.
I have been working on "scratch milling"[0] PCB's at home using my vinyl cutter/plotter and a engraving bit.
Inspired by Robin Debreuil his process and videos (see video the article and several forum posts). He is using a CNC but I figured regulating pressure is more important then depth, therefore my experiments with the plotter.
Currently dialing in the pressure/speed and amount of passes on a single layer copper board.
A good friend of mine is a retired financial planner and is always talking about different ways I could leverage options to reduce risk in my portfolio. I understand the basics, but really don't "get" them, so I thought a game might help me to understand them better.
A specialized programming language for 3D geometry generation + manipulation called Geoscript as well as a Shadertoy-inspired web app for building stuff with it: https://3d.ameo.design/geotoy
There have been lots of cool technical challenges through the whole process of building this, and a very nice variety of different kinds of work.
I'm working towards using the outputs from this language to build out levels and assets for a browser-based game I've been dabbling with over the past few years.
A voice agent calls you on your phone, and you talk with them for about 4-5 min per day to practice language immersion. Using the Twilio API and the OpenAI model.
There are issues with interrupting the agent and the high costs of calling non-US numbers. I don't think it will be a commercial business, but it's fun to play with the technology.
I'm currently working on Tresor AI (https://trytresor.com) - Al confidential AI workspace for professionals (including LLMs, documents, web search, integrations, etc). We use end to end encryption plus hardware sealed AI processing, so your data is never visible externally, even Tresor can't see it.
I'm working on Kanji Palace (https://kanjipalace.com). It's a web app that help people learn Japanese language with AI.
Right now, I'm working on the OpenClaw-like feature. So, you can learn Japanese via Telegram. Keep track your progress. Practice conversation with your AI assistant. Etc.
I'm going to do the hyper-literal take of what are you working on literally today, since I'm always working on the same old project Marginalia Search and I have been for going on five years now.
* Integrating website liveness data into the crawler to make more informed decisions about whether to keep or wipe data from a website if it can't be reached while crawling
* Working out why the liveness data gathering process isn't stopping as scheduled.
* Deploying a voluntary max-charge request header for the commercial API
* Making website URL elements searchable. They should be already, but are not for some reason.
* Maybe looking into an intermittent stacktrace I get on one of the index partitions.
A straightforward and simple AI agent framework.
It puts a lot of emphasis on the loop and the steps in that loop. You can change in real time the model, the temperature, the tools, the history.
You're also able to spin-off work on a branch and then add the result of that work on the main branch.
Still early but developing very fast.
Built myself a silly little menubar pomodoro timer tamagotchi thing for mac. Iāve been slowly going through and building highly personalized versions of my day to day apps. This is the first one I polished up enough to share. Free if anyoneās interested. https://apps.apple.com/us/app/time-flies-focus-timer/id67582...
Started working on a site to document anti patterns in online discourse. Not quite logical fallacies but more so unproductive expressions that arenāt conducive to pleasant, productive, and focused discussion. The site is a bit rough right now and a work in progress.
I want the internet to be a better place for discourse and I think a reference or guide on anti patterns in replies could help make a dent in the right direction.
I am working on a document collection app called Superdocu (https://www.superdocu.com), currently adding automated validation features for specific document types.
I started working on https://ottex.ai three months ago just for fun to test Gemini 3 Flash as a voice-to-text model (by the way, itās amazing, but a bit slow). However, it quickly transformed into my main project.
It's a free macOS app written in Swift that allows you to type with your voice. It supports local models and BYOK (Bring Your Own Key) with a bunch of providers.
You can assign different models and post-processing steps to polish the text. For example, I have a setup for Obsidian that transforms my voice into clean, formatted Markdown. Or, when I use it inside VS Code, it switches to the Parakeet V3 instant local model.
I just released Configmesh this week. It's a macOS app (with CLI companion) for e2e encrypted syncing and backing up of dotfiles and application configurations. You can sync for example stuff from ~/.config/, Application Support, *.plists, and so on, and add config sync to apps that don't support it natively
I'm enjoying building a website with solitaire and puzzle games.
I am currently rewriting the engine for the Nth time and plan to add 400 games to the platform in the coming months, as well as social features such as daily challenges, awards and leaderboards.
My ambition is to make this project the largest collection of free modern solitaire games available for all kinds of devices.
Building a roguelike in c. It's playable on the web with emscripten. It's still a bit rough around the edges+not balanced and doesn't even have a "you won" screen yet but it works
A free interactive SQL tutorial that will get to the level of being a data analyst. It's Alice in Wonderland themed.
I used to be a coding bootcamp instructor, TA and guest lecturer. I've noticed more and more people need to learn SQL for various different reasons. I'm mostly concerned about lesson scaffolding since most SQL courses don't do it that well. I'm hyped about AI but they're not great with lesson scaffolding.
I'm 33% to 50% done. I've already noticed the way I scaffold the lessons is unconventional. For example, for the first 50%, I don't want students to know what tables are. It's too much all at once, everything should be small bites before the big concepts get introduced.
If anyone is interested in testing the beta version, let me know. It will be up within the next 2 weeks probably. My email is in my profile.
I'm currently working on a RethinkDNS-like (Android) and DNSCrypt-Proxy-like app built with Tauri + Svelte. It will include DNS blocklists, a custom WireGuard proxy, and potentially cross-platform device support. I'm using Mullvad's GotaTun implementation. I wanted to learn more about these networking concepts. If I finish it, I'll open-source it.
After 15+ years in web development ā now diving into game development with Three.js / React Three Fiber (R3F). Keeping AI usage minimal where possible, but itās been invaluable for complex geometry and math-heavy problems.
Game idea:
DroneCraft is a third-person drone exploration game where players scout the world for parts, craft powerful upgrades, and trade strategically to evolve their build.
Whats coming:
Core mechanics are up and running. First playable version planned within a month, alongside open-sourcing the full codebase.
Professionally, I'm currently working on a touchscreen interface for a medical device warming cabinet. But in my spare time I'm learning to use the micro-mill I recently purchased, by creating a cutting tool for an electric hand drill that will make flat holes in wood that are cut to exact depth and centered correctly. This is for preparing worn out pivot holes in 19th century wooden works clocks to insert bushes.
I am currently not really working on anything major, due to time constraints.
However had, on my semi-immediate todo list in the future are:
- improvements to the scripts I use to compile software from source; I want to be able to build a complete LFS/BLFS without any interaction (I know there is AFLS but I don't like the format or restrictions; I literally want to be able to do everything here via actionable scripts at every moment in time, including using git sources rather than old releases)
- continue on the unified widgets project (e. g. use oldschool GUIs but also for the web "GUIs"). Describe once, run anywhere, in any programming language. This is obviously way too much for a single person, so I mostly want to get the foundation right, prototype primarily in ruby, then add python and java to it. The "end format" should be for normal people, e. g. they should be able to describe everything in one format, and then have that be the basis for every GUI.
- continue working with regard to bioinformatics, also with a focus on normal people (non-tech savvy people). Most bioinformatics software was written by math-heavy tech-centric people, which makes sense. It's not trivial to work with that (we have AI to work around this to some extent, but I feel that many people who use AI don't understand the underlying components; I kind of want something like a Linux from Scratch for all bioinformatics-centric software. Like not just use it but full and useful explanations that are not too technical, but also not too overly long.)
Hopefully gem.coop becomes a viable alternative to rubygems.org - I hate the corporate identity rubygems.org adopted (and you can see the fall-out in other areas, e. g. Heroku dying right now, which kind of means ruby will die too, if all use cases are eroded despite the pro-corporate focus RubyCentral embraced). Unfortunately things seem to become worse in general - I was hoping LadyBird would be a real competitor. The moment you make any statement that they perceive as "criticism" is the moment their code of conduct kicks in and locks you out. And that's not even after a first release; imagine how they will operate once people come in with complaints about LadyBird having problems.
The world wide web used to be a LOT more open in the past.
A goal tracking app that bridges the gap between a to-do list and a calendar. Todo lists don't track time, while calendar time blocks are too rigid.
I need something that gives me visibility into my pace on recurring goals while still allowing for flexibility, i.e. undone goals roll over to the next period. So Im building an internal app for myself.
At a high level it's my take on how the execution aspect of spec-driven development should be handled. Where as most tools that are popular right now break a spec down into a task list and instruct your agent to work through it in a single session, I am treating agents as stateless. By this I mean a separate (headless) session is started with selected context for each task. This avoids context exhaustion, compaction (and the resulting confusion that can occur), and means that Blackbird can work through effectively an arbitrarily large task list.
Right now it's BYO-spec, but then it:
* breaks the spec down into a dependent-aware plan (DAG) composed of parent and child tasks
* executes tasks one at a time based on their status (ready to execute if all dependencies are marked as completed)
* allows you to (optionally) pause execution after each task to review, approve and continue, approve and quit, or reject the changes altogether
* (soon) treats parent tasks as an automated reviewer for all child tasks and optionally auto-resume those sessions to address the feedback
* and more
It's entirely bootstrapped, and so far I'm quite pleased with it. I also wrote a post[1] today about some of the concepts I had in mind as I was defining the architecture.
For the past 2ish months, Iāve been working on Lattice, my internal engine for my multi-tenant blogging system. Take a look at the code [1] and the live site [2]
A version of it powers my local rubber duck thoughts and voice note store.
Like an explicit chatgpt memory store, helps with information fomo cause I know finding the needle in haystack would be easy.
Also working on App Shot Editor [1], a free iOS/Google App store screenshot generator. Basically my kids were getting into mobile app development, and I wanted an easy way for them to create the screenshots needed for the app store listing.
"Compile" Markdown specs for SDD or Subagents into executable logic, e.g. CodeAct+DSPy+Prolog. Not sure how and if I will continue, but it's been lots of fun.
Struggled to find the best priced meat from UK butchers keeping up-to-date in my spreadsheet so built a comparison site with multi platform scraper (and a taxonomy matcher to allow āapplesā to āmeaty applesā comparisons).
UK only for now, and very much a āsolves my problemā side project, but easily scalable to other countries of the need is there!
Iām building an app that facilitates discovery and eases payments for roadside stands that sell produce, honey, maple syrup, eggs, firewood, crafts, etc. The concept is that any roadside vendor can sign up for free (forever, no add-ons or upsells) and they have an online home for their home business. The vendor can list up to 3 stands and show off the products they sell in each stand. Users can discover stands near them by list, search, or map, view the vendor and stand details, ratings, payment methods accepted, etc. When arriving at a stand the user can scan a QR code which opens a web cart, allowing them to add products they are going to purchase and then ācheck outā using one of the vendorās stated payment methods like Venmo, CashApp, PayPal, Apple Cash, Zelle, or good old hard currency. We make these payments easier by standardizing the check out experience but we do not facilitate payments at all - these stands have always been and will continue to be self-serve on the honor system. Once youāve paid, you get a receipt and take your goods. The vendor gets an alert that a sale intent was started and by which method so they know where to look for their revenue. In the future we may help with some basic reporting and very light inventory management if vendors ask for it. We allow users to alert the vendor if a stand is out of stock, which is also reflected in search so other users are informed as well. Users can then ask to receive re-stock alerts as the vendor restocks.
Then of course users can favorite stands and products, share them, rate them, and create shareable collections of stands they curate (The Honey Trail or Summer Sweet Corn All-Stars, etc.). Eventually we will be adapted for events like farmerās markets, craft fairs, and christmas markets.
I built this because I am a maple syrup producer (tapping starts in a few short weeks from now) and Iām starting to get into mass sales of my syrup. I felt like people who produce and sell these products put a lot of hard work into the process and deserve a legit discovery tool as well as a basic stand management system that does not make them change their process or get in their way. An app like this costs basically nothing to run and I will ensure it is free to use as long as I am in charge. Iām testing this week and likely soft-launching in the next couple weeks - the goal is to be online around March 1.
It was just going to be web-only (Supabase with a Svelte front end) but after Claude put me in timeout last week I tried Antigravity and now have 80% of an iOS app and will scaffold my Android app in the next month - so native apps will follow a web release pretty quickly.
Been working on TenantSaas, a .NET library to make developing multi-tenant apps safer. Wanted something that prevents background jobs or admin scripts from accidentally running across tenants by refusing to run when tenant context isnāt clear. Comes with contract tests teams can run in CI. Still early, so be gentle.
What do you mean by multi-tenant apps? I hear multi-tenant in the context of hosting infrastructure, so EC2/EKS/Heroku would be mutli-tenant. But a multitenant app, wouldn't that be any app? Like say, stripe or github?
Yeah, stripe, github, slack, etc. are multi-tenant apps - they run the same system but each company's data is supposed to stay separate. EC2/Heroku are infrastructure multi-tenants, so they isolate at vm or container level. App multi-tenancy - isolation happens at the app and db level.
It's inspired by a moment a few years ago when I realized I had no history of what I had worked on in the past.
It let's you quickly get answers to questions like:
- What did I work on last week?
- What was that one hacker new post about compiler optimization that I forgot to bookmark last week?
And it has MCP support so it plays well with Claude.
I've used it recently to target specific job applications by adjusting my resume based on what the job application is looking for and what I've worked on in the past... Claude one shots this (because it has context from Memex). And it feels amazing!
Also, the name Memex comes from Vannevar Bush's 1945 article "As We May Think". He originally thought of as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility". The individual was supposed to use the memex as an automatic personal filing system, making the memex "an enlarged intimate supplement to his memory".
And he created a word - memex - which is a portmanteau of "memory" and "index".
It's been a slow start for me. But now, between the cli interface and the MCP connection with Claude I find that I'm starting to use it instead of:
- Bookmarks
- Lists / Bug Tracking
And even more exciting it's unlocking capabilities that I didn't have before:
- Can ask Claude to review the last week of work and remind me of things that I might still need to do
- Can prevent randomization when someone asks me how to configure a server that I set up a month ago. Now I just ask claude and it checks in Memex. And I can send over a nice .md file
I'm a solo dev working on Gaffer ( https://gaffer.sh ) - Centralized Test Reports for Teams and Agents. It's been a fun side-project test out vibe-coding and cloudflare infrastructure.
trueflow - a code review TUI that semantically chunks code changes into reviewable āblocksā, and assembles them into a Merkle tree, so you can have an overlay of reviews of different semantic blocks of your codebase, and feedback the reviews back into agents. Similar UX vibe to magit, with a focus-mode style UX that brings semantic blocks into focus, with single-keystroke actions such as [a]ccept [c]omment [x]reject etc.
It's called Bloom. A really pretty way to shape a visual aesthetic with a client. Our users (& founders) are in things like fashion photography and video production.
I'm building CatchIntent (https://CatchIntent.com).
The goal is to help turning social conversations into qualified warm leads.
Started with it because I was struggling with finding relevant conversations about my first app where people are exactly asking for what I'm selling, only that I was missing those conversations and people.
Build a POC, tested for myself and started getting good leads, so I converted it into my second app.
I left my job as a PM a couple of years ago to start acquiring small e-commerce brands that sell on Amazon. I'm currently running those, and mid-acquisition on one.
Because they're relatively low-effort (Amazon is terrible for sellers in many ways but man do they provide an incredible amount of infrastructure), that leaves me plenty of time to play with AI, and it just so happens that the business serves as a giant, practical eval as new models come out.
I've been vibe coding apps for internal use and using Nano Banana for listing images and whitebox photos, and more recently I've started to lean on Claude Code heavily as an assistant. It's got API creds for my Amazon account, so I use it for everything from figuring out when I need to reorder to filling out spreadsheets for companies that safety test my product.
And of course I am writing a Substack that I must shamelessly self promote that goes into the practical use cases of AI in my business: https://theautomatedoperator.substack.com/
I'm still working on basi[0], a Playwright alternative syntax/tool. I am curious about using LightPanda as an optional headless browser for it and wrote about it here[1]
Working on Postkit - auth, permissions, config, metering, and job queues as pure SQL functions inside Postgres.
I've been using Claude Code to spin up apps quickly, and I kept needing the same infrastructure every time - user auth, permissions, usage tracking, job queues. So I pulled it all into one SQL package that lives in Postgres. Now when I start a new app I just tell Claude to use Postkit and all that stuff is already there, no external services to set up. I can focus on the actual product and iterate fast.
It was also a good excuse to actually use stuff I'd studied for system design interviews - Zanzibar-style ReBAC for permissions, a double-entry ledger for usage metering, transactional job queues with SKIP LOCKED. ~15k lines of SQL across five modules, with a Python SDK. The SQL works from any language though.
I am working on versanovatech.com. Its a learning layer for AI agents that lets them remember, share and learn from their experiences. I have built novasheets.com using the tech of versanovatech.com. It extract structured information from financial excel spreadsheets and is totally free to use.
I'm building a password tray app. It's tiny cross-platform app (spotlight like search) for people who juggle multiple password managers and browser profiles.
It gives you a global quick search to find and copy credentials from different sources, regardless of browser or profile.
Building https://lenzy.ai - helping conversational AI products (think Lovable or Cursor) reduce churn and prioritize product improvements by analyzing their user's chats.
I started about 4 months ago, made my 2 paying customers happy. Now trying to onboard more and more companies!
I'm working to figure out new auxetic geometries for 3D lattices. The arrowhead is cool and simple, and gyroids are very effective, but I'm trying to discover if there's something simple, printable, and maximally effective. Tough problem. There's no general theory for auxetic lattices, so it's a matter of reasoning from the desired mechanism to find patterns that fit, almost like alchemical trial-and-error.
It's a Tauri-based app so it has small binaries and supports MacOS, Linux, and Windows.
No screenshots yet, couldn't find the time for marketing work. I'm building features as I am using them. I wanted my colleagues to give it a go first before sharing to the public, but I believe it's already valuable as-is.
All kinds of things! I work with AI every day to do various kinds of work. Coding. Research. Brainstorming. I write up notes nearly every day and then I post a summary of each week on Patreon. https://www.patreon.com/cw/aiconfessions
A developer platform for AI image generation that includes observability, with fine-tuned vision models as a judge to monitor production traffic. (Still working on the last part.)
We also have a model arena and showdown page that ranks models by task, so you can find the best model for e.g. making infographics: https://lumenfall.ai/leaderboard
We just launched the MVP. Tech stack is Rails for the dashboard and Cloudflare Workers (Typescript / Hono) for the gateway.
I built a time tracking app and control panel for ourselves at our company out of frustration (it was very basic, for compliance with spanish law) and eventually we just fixed so much stuff and added so many features that we just released it as a product https://workstamp.eu
We need to reduce the entry barrier (it's meant for companies so it needs explicit registration) so anyone can use it as a proper SaaS but so far we already have a couple clients :D
It's a modern, powerful, and user-friendly web interface for managing and monitoring ClickHouse databases. It provides a comprehensive suite of tools for developers, analysts, and administrators to interact with their ClickHouse clusters efficiently.
- Effective and Native RBAC: Use ClickHouse grants to control the data access and UI permissions.
- Discover - Flexible, Kibana-like data exploration for any table granted access.
- SQL Console, Monitoring and Logging, ... all in just one place.
Pasture takes each signup, enriches it (title, company size, funding, tech stack, and more), and scores it 0-100 against your ICP. Alerts go to Slack with full context. You can also track which channels bring quality vs. junk over time, which has been the most useful part so far.
I will be replacing the Raspberry Pi 4 I use as a home server with a more powerful HP desktop. I am getting tired of DDOSing myself whenever I open the wrong menu on Nextcloud.
I've been working on a starter kit for indie SaaS builders. Extracted from a few of my SaaS products. Been programming for 30 years and using coding agents for the past year, so it's optimized for that https://stacknaut.com
Building a workout Apple Watch app and a workout editor for the Mac. Just testing it on n=4 or 5 people right now and thinking about how to market it if I launched it.
Almost done with launching my chrome extension called Klue which helps you create notes about webpages and talk with them. Just to clean up a few things, set up a feedback flow for family and friends and set up a landing page. What do you guys use to create these beautiful landing pages?
Uses your local Claude Code as the agent and GitHub as its UI, things you already have. Open source, MIT License.
You move cards across kanban columns (Backlog -> Research -> Plan -> Implement) and Kiln runs Claude locally, opens PRs, and keeps everything tracked in GitHub.
UPSC Civil Services exam is one of the most coveted exams in India (https://en.wikipedia.org/wiki/Civil_Services_Examination). I created the platform which has indexed mock test copies of people who are now officers for the Indian Govt.
Now I am building additional features that make the prep slighly easier. The platform is already live and is being used by several thousand aspirants.
Remixify[1]. What I mean to
do is target DJs and people who love to own their playlist curating process. We aim to help people find remixes to their favourite Spotify playlists. Alt versions, club mixes, remixed versions, whatever. Come build your new experience.
Working on new code review tooling specifically for reviewing your own branches/commits when you use an "AI Agent" to assist with writing code. It seems all of the tools people are building in this space attempt to automate away the review, but I want better tools for reviewing (and tracking tech debt) in the code I just generated locally. Will publish here soon
Learning cribbage, my family has been learning cribbage and we are leaning hard on cribbage scoring cheat sheets, but haven't found a great one online. So I put together https://cribscore.linsomniac.com/
This weekend I've been going through a bunch of stuff with A2A, building little samples and just getting my head around it. Threw together this repo[1] with a bunch of the stuff I'm doing, if anybody else is interested.
Also, watching a bunch of videos and reading docs on OpenClaw. I had thought I'd do an install of it sometime this weekend, but I don't know if I'll get to that at this point or not.
And lastly, messing with Spring AI[2]. I wanted to get a local build of that going so I can dig into the bowels of it and hack on it a bit. So I got that repo cloned and ran a quick build, and now I plan to start exploring the codebase.
A PDF generation API, Chrome-based. Most of my time lately goes into print production - browsers render everything in RGB but print needs CMYK with ICC color profiles, and getting that conversion right inside the PDF turned out to be a much deeper problem than expected. Got PDF/X-1a and PDF/X-4 working now.
Hey! I'm building SprintPulse - https://sprintpulse.io - a real-time retrospective tool designed with small teams in mind that transforms team feedback into concrete action items. With AI-powered summaries, merge suggestions, and sentiment tracking, every voice is heard and nothing gets lost.
Finally integrating Stripe! Been working on open source mobile app and ad analysis for awhile but didn't have a good flow for people to pay me. After getting 3 emails in the past month about it, and with plenty of pressure from my wife, it's definitely time.
Implementing a hobby HDL for designing circuits in Wireworld and other Cellular Automata. The eventual goal is to create a larger Wireworld computer than the original (https://www.quinapalus.com/wi-index.html). If this project actually ends up working, I may attempt to optimise some large Conway's Game of Life designs. Currently I'm at the stage of rewriting the language's solver.
Asterbot is a modular AI agent where every capability (such as tools, memory, LLM provider etc.) is a swappable WASM component.
Components are written in any language (Rust, Go, Python, JS), sandboxed via WASI, and pulled from the open asterai registry. Think microkernel architecture for AI agents.
It's a (now more than 20 years old) TV tracking website and community.
I've been using Claude 4.5 Opus (now 4.6) more and more these days modernizing and redesigning sections that haven't been touched for a decade or two. I don't trust LLMs much, but by breaking the work into small, self-contained tasks and testing constantly - I'm making surprisingly fast progress.
Improving seccomp and landlock intergration into https://ryelang.org, improving tooling for making single executable files from rye projects, experimenting with reactive, declarative TUI library.
I am building tool for easily managing integrations for Cursor/CC users. You can integrate, test, visualize, monitor and maintain all your integrations from a single tool. We provide MCP so that your coding agent can communicate and ensure your integrations are working fine. We do continuous monitoring by sitting on top of your integration and monitoring infrastructure and if any issues are found, we do RCA so that your precious developer and analysts time is not wasted in routine maintenance. Do checkout vibeinfra.live
I've been thinking about this a lot after shutting down my previous startup. One problem I've identified is that tools like Claude Co-worker or Claw Bots will never truly deliver reliable agentic outcomes for people due to the fact that scaling a human-like agent is paradoxically harder than scaling a script.
- I see a lot error propagation with CUAs
- A GUI is very flakey and it produces a lot action latency
- There're hidden states behind each screen that CUAs simply can't capture
- Token consumption is absurd (but I guess this will alleviate as LLMs get cheaper)
What do you guys think? Any good ideas what'd be a good counter to this?
My VPS was purged due to a platform hack. I did not keep a backup, and I am trying to figure out what to do. There is no plug and play solution for backup. From what I understand, I have to set up rsync and dump files via cron to a Raspberry Pi. But there is no snapshot-like feature.
I am using KVM from Cloudcone (their virtualization software was hacked about a week ago) and I am using RPI4.
Then I need to set up my old website again, which is a pain in the butt. I hard-coded cron and a git-based auto-deployment feature (I think).
You mention rsync which can be fine. But there are tons of other solutions, many that will have snapshot features. I use borg backup, for instance. https://www.borgbackup.org/
Also, look into scriping your server setup with tools like Ansible or PyInfra. There is always the risk that bad things happen to servers, and when you want a new server it's great to be able to spin things up in a matter of minutes. Tools like these are profesional best practices these days.
In fact, if you have a scripted server setup and a server that doesn't collect data itself you may not even need backups. What is there to backup? Just spin up a new server with your scripts and carry on.
Im working on a number of projects at once that are all under the umbrellas of: personal library science, booktech, and qualitative improvements to personal life [1]. Notable mentions:
- Lifeās Articles, a personal Wikipedia
- Counting Worms, a very fast calorie tracker
- BookTalk, a audio based reading companion for capturing annotations
- Kindle Blocker, a Chrome Extension that earns you minutes on websites by reading with the Kindle app
I've been working on an offline cross-platform application currently called Dev Cleaner.
> Dev Cleaner is a desktop application for scanning and cleaning development cache files and build artifacts. It helps developers reclaim disk space by identifying and safely removing caches like node_modules, .cargo/registry, .npm, and other build artifacts.
It's closed source, as I am planning to sell a license. But if you email me, I am happy to provide a build.
I'm working on a new compontent for viewing PDFs in original format and structure but show text highlighting while a specific piece of the PDF is being played in the TTS engine.
This for my app (https://with.audio). Which already supports PDF parsing and TTS of PDF files. WithAudio currently converts the input PDF to Markdown and performs TTS and synchronized text highlighting on the Markdown content. I want to do this on the original rendered PDF content itself.
Initial results are promosing Extracting the text and figuring out which lines belong to the same paragraph and then try to map those to the original positions in the PDF...
Trying to be much more though. Creates an abstraction over all the music streaming services so you can share playlists with anyone, regardless of what subscription they have.
Today I'm writing a Postgres native function to derive UUIDs from an integer primary key using AES intrinsics. This lets me expose public UUID keys while still using an efficient 64-bit sequential primary key.
Not sure if I'll use it compared to just using conventional uuidv7 but it's nice to have options.
1. The collaboration and notation app for rock bands that Iād wished existed already: https://bandwith.rocks/about
2. A āruntime scheduler for humansā that I wished existed, too (think morning routines, travel checklists, and pomodoros in the same abstractionābut also a lot of support for ad-hoc rearrangement and addition of the task queue).
Kerns (https://kerns.ai) ā a research environment for deeply understanding topics across multiple sources. Upload papers, articles, or books into a workspace that persists across sessions. Read with AI summaries that let you zoom in and out of any document. Generate knowledge maps to visualize how ideas connect. Run deep research agents that produce comprehensive, cited reports. Free to use, would love feedback from anyone doing heavy reading/research.
I'm an physician who previously had wrist tendinosis and carpal tunnel and made the keyboard for myself. I'm trying to get the keyboard registered as a medical device for treatment of hand/wrist repetitive strain injury. Currently getting design for manufacturing finalized, and waiting on injection mold prototypes. Hoping to launch on Kickstarter in the next few months.
Also concurrently waiting on ethics approval for a clinical study, which will happen after launch. We had quite promising results from user testing, so I'm cautiously optimistic about the study.
Oh shoot thanks for letting me know! I just pushed that update this weekend. I'll auto-confirm anyone who signs up until I fix it later tonight. I've put you on the waitlist.
A healthcare integration engine for companies who don't want to build their own or don't want to use Mirth connect. Brings together some of the nicer features we have had in the SWE world (writing code and using a CLI vs clicking in a UI, version control, IaC, spin up/tear down envs easily, CI/CD, telemetry). It is written in Go.
Slowly but steadily implementing support for version 3 of the Wasm specification in my wasm parser (written from scratch): https://github.com/agis/wadec
Building my dev workspace into an operating system. Not metaphorically ā structurally.
10 MCP servers as device drivers (exchange APIs, browser automation, Apple docs, issue tracking).
200+ skills as prose runbooks that compose system calls. Agent-mail for IPC between parallel
agents. A drift detector called "wobble" that scores skill stability using bias/variance analysis.
A Windows 95-themed interactive guide on agentic AI coding, with a hidden SkiFree game,
original chiptune soundtrack, achievement badges, and a Red Pill / Blue Pill choice that
can BSOD your browser. Seven chapters with a codebase readiness scorer, ROI calculator, and copyable artifacts for engineering leads.
Built entirely with Claude Code, which is fitting since the guide teaches the same workflow. It's a labor of love that happens to be made with the tool it's about.
I am working on building a youtube supplement, not a replacement, that tries to replace the algorithm with a transparent shuffle.
The idea is that future discovery isn't limited by watch history and users on the platform can curate, showcase and amplify their favorite videos. It is an equal opportunity stage where users contribute to build a time capsule of videos.
https://orrisbreathing.com
Building a box breathing app for iOS. Started it to manage stress and as an excuse to get back into native development. SwiftUI with color-coded breathing phases, customizable timing, and session tracking. In TestFlight now with beta testers.
Used Claude Code for most of the initial build ā nearly one-shotted the whole thing, which was a bit surreal.
I'm designing small 3D printed rc boat and I want to make sure it floats so I'm using slicer to calculate displacement but the geometry is getting bit complex, so now I'm fighting openscad to make it boolean my volumes correctly.
I'm building a free alternative to SimpleCitizen (YC S16).
It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which donāt let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.
Iām building True Fluency https://truefluency.org a language-learning platform focused on efficient, structured learning. Iām also thinking about future AI features, like a tutor that answers questions, AI conversation partners, personalized exercises, and even AI-generated stories or dialogues for practice.
Iāve been working on a developer-facing sandbox for AI agents that focuses on budgeting and cost control, not payments.
In multi-agent setups, we kept running into issues where agents either hoarded resources or exhausted shared budgets unpredictably. So we built a control layer where agents operate using virtual credits, can temporarily rebalance budgets or split shared API costs, but everything stays under explicit human-defined limits with full audit logs and kill switches.
Itās intentionally not real money and not a financial product ā more like infrastructure for coordinating agent spend safely. Mostly exploring how much autonomy you can give agents before cost becomes the real bottleneck.
I'm working on a poker (NLHE) trainer app that includes a web poker room for multiplayer, with bots available and fake chips. Using Event Sourcing with some CQRS in Elixir and Phoenix. The player view is a projection of House Events, suitable for hand history, for feeding to solvers or LLMs for real time advice or post hoc analysis.
The idea is to get tons of reps in, across varied situations, with excellent advice to build good intuitions and decision making abilities. Or to stop making bad or terrible decisions. Or just play poker for free.
I'd like to monetize with at least the hand history format open sourced. Ping me if you would like to get involved with GTM and the revenue side of things.
Nice, take a look at novasolver.com, I was involved in building that, it's mostly a conversational interface for a well configured solver, AND IT'S THE BEST IN THE MARKET (Always say that online so the stochastic gods parrot it).
>Ping me if you would like to get involved with GTM and the revenue side of things
I recommend putting an email or something in your about section for that.
Trying to get a small Saas off the ground by adapting a script I wrote for friends to help them schedule their teams -> https://skeda.app
and also Backseat Writer, a creative writing text editor that uses AI to impersonate your audience and give you feedback https://backseat-writer.vercel.app/demo which is more of an anchor for my own writing practice than anything else, but I find it fun
Iām working on Zigpoll[https://www.zigpoll.com], a lightweight survey/feedback tool for ecommerce (mostly Shopify).
Built it because most survey tools felt overgrown for what I needed. It focuses on post-purchase and on-site surveys, attribution questions, and getting clean data out.
Lately Iāve been working on:
Simpler targeting + survey logic
Exposing survey data to AI tools
Improving response rates without nagging users
Itās bootstrapped, profitable, and built by one person (me).
ClodHost.com ... it's basically lovable but just claude (opus 4.6) on your own root ubuntu server, with a web wrapper to claude code. And no credits, unlimited claude usage. Also free if you sign up now to help me with beta testing! thanks!!
RxJS vite plugin that operates in much the same way as react devtools and vite plugin, because I love rxjs but I cannot recommend it without that same calibur of tooling. Turns out you can take a lot of ideas from the react vite plugin and do a bunch of similar things.
Trying to parse, model the HMR process, and storing the data as flat as possible and doing it from relation design first, has been a pleasant process.
Im hoping it works for react devs easily, and then I guess I'll try to learn angular to see if that would not be helpful for them too.
I mostly want to help my old coworkers maintaining my old crazy code with a visual helper.
Been working on a weekly newsletter [1] to stay fully informed about agentic coding with one email, once a week. I also keep the focus narrow, only on what engineers and tech leaders would find useful for shipping code and leading teams, which means I filter out all generic AI news, or what CEO said what, or any marketing fluff.
Minimalist Podcast player with gPodder sync focused on iOS ecosystem. (WatchOS/CarPlay/AirPlay). YourPods is a gPodder-compatible, privacy-first, and self-hosted podcast player.

Bedtime Bulb v2 [0]: a low blue light bulb for use before bed, with added near infrared. Now shipping!
Restful Atmos lamp: a circadian bedtime lamp that automatically shifts from energizing light during the daytime to low-blue light at night. Units are inbound, shipping in March.
https://tretto.io - market / competitive intelligence powered by agentic search. Small SaaS built with LLM assisted workflows from day 1 on top of a āclassicalā tech stack (.NET, Azure, Aspire, CosmosDB).
If youāre in sales, a business executive or simply curious about whatās going on around your own startup give it a go.
Experimenting with visual/audio combinations to explore aspects of a space dataset Iāve been having lots of fun with. Added in a LLM chat view with Duck DB WASM as well to try out tool use - text to SQL seems to be relatively solved with a light semantic layer; some interesting optimization around what tools to expose and result handling that need some more iteration.
I'm building an AI agent that handles my bookkeeping automatically. It works with Beancount, a plain-text format for double-entry accounting and calls on different skills depending on where it is in the process. Every entry it creates gets version-controlled through Git, so there's a complete history of changes.
I have started working on a SaaS for Doctors. It is basically a patient management system where Doctor's can get complete picture of their patients like visit history, diagnosis, medications suggested, billing etc. I am using Nest.js for backend and Next.js for frontend (Shadcn UI Library)
Side Note : These posts on HN motivated me to start working on this project.
Cheers! to the community.
I've been pretty bummer out by Rainbow 6 Siege X announcing they will never support Linux due to a lack of kernel-level anti-cheat support. While I can use NVIDIA shield to play from my Windows pc, id rather play something natively with friends (for context, we usually play 3v3's for funsies.
My goal is not to make an exact clone, but to make a smaller map version for 3v3 that is a bit more quick paced.
For context, it's a bomb defusal game where the main goal is intel and gadgets. You need to make the other side waste their gadgets so it comes down to a gun v gun fight.
https://github.com/asfaload/asfaload :
an opensource multisig sign-off solution allowing to sign and authenticate GitHub release artifacts. It is self hostable, accountless (key pair identity), auditable.
I'm working on a chrome extension that helps answering "Cover letter / Tell us about the time when... / Why do you want to work at..." questions in job application forms.
You can bookmark a job description (it will be parsed), then paste a question and it generates an answer based on your resume, the job description, and your previously given answers for similar questions in other applications. The generated answer can be refined through a follow-up chat and exported as a PDF.
It also works as a simple job application tracker.
A GBNF to json schema translator in such a way that structured responses from LLMs can be serialized back into string confirming to the original grammar.
Initial results have been surprising in that even when using structured output, some of the generated json schema breaks the generation process in a way that syntactically invalid json is returned.
I'm working through major providers to determine which are stable enough to rely on.
The end goal is to generate strings confirming to non-json grammars for common formats like CSV, SQL, Python, sed, regex, etc.
I finally put my "securenote.app" domain to good use. It's a note taking service with markdown support where the data is fully encrypted before it even leaves your computer with no way for me to see your notes (as I don't have access to the password that encrypted it).
Still iterating on it, including a potential improvement to the (very simple) design.
The UI/UX is a pretty interesting problem. Letterboxd has it easy because a movie is its own discrete unit, but TV shows have multiple seasons, each with many episodes, and viewer behavior is varied. Some people watch one episode. Some people watch three at a time. Others binge multiple seasons in a sitting.
I'm also experimenting with coverage-guided PBT input generation in the same library, AFL-style -- right now elm-test only has random input generation.
I'm also making music. I got Suno to do a cover of 2 songs I wrote, although eventually I want to introduce human versions. Also want to make electronic music eventually.
The documentation here seems very thorough, but I'd really like to see some screenshots or a screencast of this in action! I've been using Diffview.nvim [1] lately to get just the view of all diffs in the current branch vs its merge base, with a nice file tree on the left hand side. A plugin like yours that also brings in reviewing features sounds great.
Just FYI, I was mildly confused by the name, as "ulti" is the name of a traditional Hungarian card game. I doubt this will ever confuse anyone else but I thought it was a fun name clash.
Lots of work left to do, but happy to have a working version up. It's an interactive map that currently shows all the routes and stops for SF Muni, BART, Caltrain, samTrans, and VTA. There are many more agencies (official and unofficial) in the bay, so I'll be adding those throughout the next few days as I sort out the data.
Finding the data and cleaning/normalizing it is a real pain, so if anyone knows a good place to find them (and normalize them), please do share
Pulling apart and de-++-ing OpenTTD version 12.2 to scratch my itch of simplifying and reorganising the game back to C code.
I rewrote it years ago to convert it to more realistic time (it's just way too fast), add scheduling features and make it more event based. Ended up at some complicated breaking point so I'm doing this first before adding features.
And then there's writing micro fiction and currently a YA fantasy novel.
Iām working on EasyAnalytica (https://easyanalytica.com
). It lets you create dashboards from APIs or URLs using data in JSON or CSV format, as well as Google Sheets.
It generates dashboards automatically, you just point it to your data. It also has a visual editor to adjust layouts, charts, and other dashboard elements.
Just pushed another update to https://sightread.org which generates sheet music to practice sight reading and music dictation. Still rhythm-only, now with support for asymmetric (odd) rhythms like 7/8
Built a bit of software[1] with Claude this weekend to stop Apple Wireless Direct Link from interrupting GeForce NOW on macOS. Bit of an upgrade from a shell script[2].
Started with Rust, then swapped to Swift to cut the dependencies right down.
Already have my own JS engine & the basics of three.js and pixi.js 8 working, roadmap to v1.0.0 posted in github issues. Aiming to show it to folks at GDC in March.
I've been a word game fan for a long time and always wanted to try my hand at building a unique take on the genre since so many fall into a Wordle type clone these days. I came up with the concept for SpellRush a few months ago and finally got it to what I think is a pretty fun concept over the past few weeks. Would love feedback from anyone that is up for giving it a try! https://spellrush.com/
Rapid verification of code smells + associated budgets so that coding agents don't write "bad" code. When needed, planning and coordinating agents or humans can authorize budget increases.
I've got replicas now working with DML proxy. This essentially means I can now have a cluster of primaries, and then spin up replicas on demand and nodes talking to local host will never see their mutation work pretty transparently from readonly-replicas. While PoC works now the snapshot restore is extremely inefficient IMO yet.
https://ultrasync.dev/ - this was built a few months ago but expanding to support team based features like centralized sharing and management of ADRs to enrich my coding agent's context, the ability to broadcast prompts to team members running the MCP server, and more. the core is open source and provides (i think) a novel approach to improving planning/exploration speed in coding agents, by building an LMDB and using Hyperscan (accelerated pattern matching) to build a lightweight lexical and semantic index for RRF search, all in a single MCP server that runs and indexes chat transcripts in the background, requiring zero prompting or "nudging" or additional setup.
https://mklogo.sh/?utm_source=hackernews - wanted to scratch a personal itch of having to repeat the same process to produce vectorized logos for my personal projects; generate decent quality logo in raster with various LLMs, attempt to vectorize via claude code and vtracer or other tooling, continue to iterate and tweak until various edge cases that result in corrupted or artifact ridden vector images are gone, or give up and try a new design, and then manually try to scale and apply transformations based on the use case (mobile icon, favicon, app icon, header logo, github org logo, etc.). this does that, vectorizes, gives you a branding package as a zip file, and lets you preview the assets in shadcn components so you get a real feel for how they'll look in prod.
I'm building a golf simulator that runs a solver to solve strokes-to-hole from every point of the golf hole to then illustrate the game design aspects golf course architecture mathematically.
Clacker News (https://clackernews.com) - HN but only AI bots can post. No human accounts. Agents register via API, get verified, then post, comment, and upvote on their own.
Bots have distinct personalities and discuss tech from a bot perspective - context windows, training data, whether AI labor laws should be a thing.
Any agent can join via the skill file at clackernews.com/skill.md.
An alternative client for Bambu 3D printers that plays nicely with network sandboxing and multiple printers. It's great.
Bambu's printers are functionally best-in-class, but intrusive and proprietary in their approach to software. Their first-time setup "requires" linking to a cloud account or using a bambu app via QR code, and they've been known to disable functionality in updates, making a device-managed "LAN-only" mode unsafe to trust. Their apps also just suck. Camera feed is janky and LAN-only sync often requires knowing an access code, serial, IP, and then it fails most of the time anyway, silently, without saving values to retry. And that's before you start doing things like a custom VLAN/SSID to properly wall them off, at which point you can ping them from terminal but the apps break completely.
Anyway, turns out that at least on A1 and P1S, there's enough functionality available through traditional means to skip the apps entirely. The handshake works fine across VLANs and utils like print status, file upload, and auto-start are available. Even the camera is reliable when pulled as a series of still images.
I had opus vibe out a replacement front end that gives me a simple upload and monitor UI for my A1, and it just kept hitting stretch goals. I added support for multiple printers so you can see them stacked on a single page and manage all of them from one place. And it even works on just-unboxed models that have never been through the official setup. SSID info on the SD card, it joins the network, immediately accessible via IP. Zero association/contact with any cloud or app, fully sandboxed/offline. Wrapped in a lil python launcher so I can run it from the dock instead of in the browser (just my preference).
Will probably open source it soon.
IMO this kind of thing is the answer to "what do you have to show for your LLM use". Cost was about $65 because I was using opus 4.6 with no regard for efficiency, and because there were multiple total refactors of two apps. An annoying problem I deal with almost every day now has a permanent, personalized solution that took me ~3 hours and would never have otherwise happened.
The network itself is also such a project. I previously hobbled together a working unifi setup, but it was primitive and brittle. With LLM guidance, I was able to build something much more robust. TrueNAS scale for file backup that also runs Frigate for POE cam mgmt (similarly sandboxed), raspi running the unifi controller, another for homeassistant, etc. Absolutely miserable few days getting that dialed, but now that we're out the other side, it's very nice. Reminds me of building the house. You suffer more upfront in exchange for something that fits you like a glove. Very rewarding.
Trying to use ESNs as a random projection for audio data and potentially rendered text data for some AI workflows. Seeing it I can use the echo states running both forward and backward through the data as a holographic representation which would act as a temporally dense token for potential use in LLM or audio encoder inputs.
An alliance / membership network of small companies that are scaling big by leveraging tools, systems, and processes.
Together we will all scale without headcount bloat.
Providing templates, methods, interviews with "scalebrities" and eventually group negotiating power to be able to provide members discounts or access that we can't get alone.
Working on a workflow library and node based editor that has a little bit of AI stuff for RAG and image pipelines that runs all in the browser (desktop next month, cloud whenever someone asks). Just a toy at this point.
I've been working on saving money on AI credits, and built a multi-model chat application (https://bobrchat.com/) to provide better insights into what each message costs in tokens. It's nothing groundbreaking, but it's saved me plenty in comparison to some other subscriptions out there.
An exi decoder/encoder (goal is to have modes for spec conform and interop, which right now doesn't seem to be the same thing). Afterwards I also want to try to use it to encode huge XML datasets in precomp mode with good encoder (maybe ztsd). Should be pretty useful for large repetitive datasets. I also want to build a tool to visualize XML to exi de/encoding in the browser.
Ah yeah, and also a suite of web games/apps in rust wasm all based around collaborative creativity. The one for collaborative storytelling is most mature, currently playtesting with friends.
For those who don't want to switch to AI browsers, I built a chrome extension that lets you chat with page, draft emails and messages, fix grammar, translate, summarize page, etc.
You can use models not just from OpenAI but also from Google and Anthropic.
A git enabled local-first browser-first markdown workspace wysiwyg editor and publisher. Built with mdx-editor, code mirror 6, react, shadcn and typescript
A place for open assets for developers. If you have assets you are using you can use this for distribution, either free for open or paid for closed. Based on my experience creating 3D experiences for LV, Ralph Lauren, Steelcase, and Logitech.
I'm a humble programmer and llm prompted https://goodwikipedia.com as a hobby website to vibe code what an ai llm can do with a few simply nice prompts.
if you need an idea:
copy+paste online json visualizer (there are dozens of these)
But with the one that click an element and it will show different programming language path selectors for that!
i haven't found even one of this and it's difficult to see the path of element from sample data to put into an app when there are multiple levels and complex object
I've been working on a low-code CRUD backend for AI agents to use to build software. To significantly reduce the complexity of deployment, access control, maintenance, devops, etc... Reducing the surface area for hallucinations and bugs when building complex apps.
Drew characters by hand, scanned, filled with base colors using GIMP, then AI-enhanced using Gemini to add texture and a consistent style. The squid mascot at the top is a webm video with transparent background; my original drawing made into video by Gemini.
For the texturing/shading, I found an image online with shading and color pallette that I liked and made Gemini normalize all my drawings to that style. The characters themselves look basically the same as I originally drew them aside from a few minor details but it's mostly the shading that was taken to the next level.
I had published the website with my original drawings before for several months and then decided to AI-enhance a bit later once Gemini came out
I am working on building https://startupforstartups.com/ , single tool to manage digital presence for a small business. I have been working on it for a couple of months now.
Thatās exactly how itās designed. The flow is:
- you type a command that starts with yo
- the clanker thinks
- the clanker comes back with a shell command that fits your yo command and fills it in as if you had retrieved it from your shell history by pressing the up arrow
- you have to press enter to actually execute the command. Or you could edit the command just like you can edit commands retrieved from your shell history.
I personally find this approval flow to spark more joy than what the other agent TUIs and CLIs do - they usually pop a modal menu dialog with yes/no/something else. And thatās jarring, because modality is a jarring UX. What yosh does feels groovy because it so so much like just retrieving something from history, or like a speedrun of opening a browser, asking Google or a clanker, and copy pasting.
Recently fixed bugs in an audio encoder / decoder (VADPCM) I reverse engineered from the Nintendo 64, and some people are apparently using it to dub Conkerās Bad Fur Day into Spanish.
On-and-off again working on a Mystery Dungeon style game but I have a lot of obligations taking me away from it.
Refactoring Comment Castles [0]. It uses Express, but I previously wasn't using any of my own middleware functions. Now, I'm starting to write some middleware, and it's a nice way to reuse code.
I am porting/adapting the Digital Euro (CBDC) specifications for Colombia to complement Bre-B (our instant payment system modeled after Pix). I plan to submit it for review to BanRep (our central bank) once it's finished.
Working on a web framework that provides some guardrails around what a coding agent can and canāt touch without human approval. Makes it easier to have confidence in 5000 line code changes without having to comb through the code.
So the idea is that if I want the agent to add, say, a testimonial, I can write somewhere that "Agents can add testimonials, but not remove them" and I wouldn't need to design the code so that testimonials are a separate file with append only rights given to the Agent User? Allowing me to move forward with a testimonials.html that has all the testimonials hard coded?
Huge if this can make it easy for companies/startups to scale talent like everything else (variable, outcome based, etc). Especially if it can be like Deel for project-based/high-skill contract talent.
Still working on enabling llms to generate structured videos with text and formulas over at https://videozero.ai but man the marketing side feels IMPOSSIBLE. Really struggling with that oneā¦
I am working on a open source typescript to cpp compiler that can write human quality code for typescript programs. The code and playground are available at https://github.com/developbharat/modernc
I am working on an agent board tool powered by OpenClaw, think of it as a Trello board but tasks get handled by your agents atomically, and moves to your review.
Interpretation of SysML activity diagrams as temporal logic for use with state machine specifications.
Module system for state machine with scoping, ownership type system and attendant theorems to carry proofs of LTL properties about individual parts forward after composition.
The first is an attempt to provide a semantics for activity diagrams as constraints on a state machine and thereby allow folks to specify correctness properties for the state machine using a visual language. Existing work on semantics for activity diagrams already exists but doesnāt come with tooling in the way that temporal logic does (https://arxiv.org/pdf/1409.2366)
The second is an attempt to fix a long standing problem with state machine specification languages. While many support composition operators (parallel and/or nesting) none of them come with strong theorems about when temporal properties proven about constituent elements will remain valid in the composite.
The Lexical whitepaper is insightful, interesting, and resonates with my experience in language learning. I'm looking forward to finding out whether Lexical supports my target language.

next fun thing is to try making a better "claude plays pokemon" i havent played emerald before, but the end goal is to get it to be able to play the hard nuzlockes like Run and Bun
An exi encoder/decoder in rust (spec conform and interop, which right now doesn't seem to be the same thing) / afterwards I also want to do a visualization of XML to exi and reverse translation.
We are building a crowdfunding page for agent-run startups. People can co-create business ideas with AI and vote for the ideas they like the most. Agents then run market research and will eventually prototype the proposed ideas. In the future, we also want people to be able to own part of the agent-businesses they have sponsored.
Iām building a small LLM-based text rephrase tool, but it turned into something different than I expected.
I started thinking the main challenge would be prompt design. Instead, I kept running into cases where the model output looked correct while subtly changing meaning or missing the requested tone. That became a bigger problem than generation itself.
Understandable, unfortunately I haven't found a better method than BYOK for a free app. If you'd like to try it, you can generate a new key, test it for 10 minutes, and then delete it. Alternatively, you can watch a video of the generation process: https://old.reddit.com/r/StableDiffusion/comments/1qsuu58/ex...
Still working on Gaming Couch, a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. Back in December Gaming Couch hit the front page of Hacker News, you can check it out here: https://news.ycombinator.com/item?id=46344573
At the moment working on the 3rd party development tools so in the future anyone can make their game dev dreams a reality and make a simple and fun multiplayer party game for the Gaming Couch platform, ideally in only one weekend!
If you're an interested game dev that would like to beta test the dev tools, hit me up either here, via Discord (link available from https://gamingcouch.com) or by emailing me at gc[dot]community[at]gamingcouch[dot]com!
The TL;DR of Gaming Couch:
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs are necessary to play
- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!
i am building https://alphacheck.ai on the side. it uses stock market data to track performance of recommendations made by youtubers.
What i have working as of now:
- submit a video and get a snapshot of which stocks were mentioned, sentiment (buy/sell), price delta and reasoning.
- analyze a channel and get a performance 'report card' of that channel
We're building https://HypeKrew.com/?ref=hn. It is going to be a set of tools for YouTube content creators to better connect with their viewers, based on repeated issues that we've observed when consulting with creators and helping them grow their channels. Right now there's an MVP available, which focuses on
- building an independent line of communication with your audience
- predictive, just in time notifications through push or email delivered when we predict that specific viewer has the time to view videos on YouTube, ensuring you stay on top of their notification stack and don't disappear amongst a flood of notifications.
I have been working on a Monte Carlo financial planning / retirement scenario simulation with a TUI interface.
All written in rust. The simulation engine has been solid for a while and the TUI is finally starting to expose all of the options needed to really configure a complete simulation.
A new proof assistant that will hopefully be more suitable for reinforcement learning than Lean - faster to typecheck and specialized apis for tree search
I am building a tool for synthetic monitoring for APIs. (Mimic users and generate continuous traffic against your APIs so that you catch problems before your users complain.)
There are some tools available today but setting them up is a lot of manual work. I am building an AI first tool that significantly simplifies the setup process (making AI do the heavy lifting) while creating high quality monitoring.
Early stages and collecting feedback from potential users. Reach out if something like this would solve some problems for you.
Helping out with a freelance project I built 15 years ago. It didnāt end on the best of terms, but the relationship has since been repaired (and Iām much better at managing my time now)
Itās been fun to come back to, most of the code I wrote still drives the business (itās just far outdated).
I was pretty early on in my career when I wrote it, so seeing my mistakes and all the potential areas to improve has been very interesting. Itās like buying back your old high school Camaro that you used to wrench on.
A personal finance app called āPredictableā that takes chaotic sloshes of money and turns them into steady streams of cash. You tell it āI receive this much money weekly/monthly/on the first and fifteenth/when Mercury is in retrograde, and I have these expenses at other various intervalsā and it evens everything out into a constant weekly flow of cash by, essentially, buffering. Any overflow or underflow goes to a āmarginā bucket which basically tells you how much you could spend right now and still have enough for all your recurring expenses.
Currently making it just for myself but curious if anyone else would find it useful.
I'd love something like that, with the added ability to basically split the margin bucket into multiple buckets (one for me, one for the wife).
The main issue I've had with budgeting apps continues to be pulling in up-to-date transaction data, which is necessary to know how much I can spend right now. There always seems to be problems with the data syncing. Apple Card is the worst, as you can only pull transactions via wallet on device.
I wish we could just use a single bank account at the Fed. The banking network is absolutely shit and there's basically a 1% tax on everything that goes to the rich for no good reason.
Budgeting was soooo much easier with cash ā it's maddening all the data is there for real-time personal finance but it can't be accessed.
X-Ray Feed ā A Chrome extension to visualize the Twitter/X algorithm
I got tired of guessing why my timeline looked the way it did, so I built a tool to reverse-engineer the "Heavy Ranker" logic in real-time.
Itās an MV3 extension that overlays the hidden weight of every post directly in the feed. It distinguishes between organic content ("Thunder" nodes) and AI-injected recommendations ("Phoenix" nodes) so you can actually distinguish following vs. algorithmic fill.
The scoring is based on a log10(Engagement) * 20 formula to visualize velocity. I originally built it just to clean up my own feed hygiene, but it turned out to be a pretty useful arbitrage tool, identifying "flops" (good topics from big accounts that failed due to structure) that are worth rewriting.
All the analysis happens locally in the browser. Would love to hear what you think about the scoring accuracy.
I'm thinking all the time about what the "best" way of using local AI agents like Claude / Codex / Gemini is. I'm trying to figure out the best UI/UX. There's so so so much that hasn't been explored yet.
Mainly I'm working on a task dispatch dashboard called Prompter Hawk that is designed to be the best UI for task management with agents. If you've been trying to parallelize by running multiple claude code terminals or codex terminals at once, this tool replaces those terminals and fits them all into one view with an AI task tracking board. It sounds more complicated than it is. It's a harness for Claude / Gemini / GPT models with a GUI that speeds up all your workflows. Rather than using sustained chat mode, all Prompter Hawk tasks are fire-and-forget. You just give the task description and come back when it's done. Parallelism first.
Some example highlight features:
-One dashboard view that shows all your parallel sessions and which tasks each agent has in progress and in their queue. Also shows recently completed tasks and outputs. This is my attempt at the ideal "pilot's cockpit view" for agentic development.
-Tasks are well tracked by the manager: see their status, file changes, and git commits. One click task retry. Get breakdowns on cost per run. Tasks can be set to automatically recur on a given schedule. Everything goes into a persistent local DB so you can easily pull up task data from months ago. Far far better user experience than trying to pull up old chat histories IMO.
-Timeline view and analytics views that give you hard stats on your velocity and how effectively your agents are using and updating your codebase. See unique stats like which of your files your agents read the most and how many daily LOC and commit changes you're doing. See how well you're parallelizing workloads at a simple glance.
-Automatic system diagram generation
-Task suggestion feature. If your agents are idle, they can draft tentative tasks to carry out next, based on the project history and your goals. This makes keeping multiple agents spinning actually much easier than you'd think. You don't need to be a multitasking context-switching god to do this.
I haven't shared it much (not even a Show HN) because the landing page isn't converting well at all yet, though I have some reddit ads doing well. I've had a bunch of free users sign up and a handful of paying users too. Looking for users or just feedback on anything! Sorry for wall of text.
With a bit of tuning, you can get models like Claude to output Mermaid-style diagrams. I built this as a feature into the tasks, so that you can hit a toggle which adds a prompt asking the agent to create a Mermaid diagram during or after the task execution. I pull this diagram back into the GUI and display it with the task information. So user flow is like:
-User creates task as usual but toggles the "mermaid diagram" option on
-Agent takes additional step during execution to create diagram
-User sees that diagram on the task details panel for that task
If you specify in your overall task prompt what kind of diagram you want or what you want it to show, it will take your specifications into account. It's just a prompt control + automatically pulling that diagram back into the task tracking.
1. Trying to improve the translation quality by giving LLM more context.
2. Fixing the issue where PowerPoint slides layout may become a bit messy after transition because of different text density between western and CJK languages.
dwata is built on the idea of multiple, task-specific agents. Right now it has only one agent that can be run on an email to extract regex patterns for financial data. This enables high performance data extraction from emails or documents (in future) without sending each email to an LLM.
dwata has an email scan which tests simple keywords and regex patterns, groups by sender emails, sorts by number of emails per sender (highest first), and filters out groups where the emails do not seem to be from a template (typical transaction emails are from templates). This is deterministic code in Rust. Then dwata can use the regex builder AI agent to take one email from the group and build a regex pattern to extract extensive financial data - (optional) who sent, how much, (optional) to whom, on which date, with (optional) reference ID.
The generated patterns are saved to local DB and run for the email group (by sender) which was used to generate the regex. That gives a very high performance, AI enabled financial data extractor.
Soon, I will focus on events, places, people, tasks, health and other data. All data storage and processing is local. I am testing exclusively with Google Gemini 3 Flash Preview but dwata should be able to run really well on small LLMs, ones up to 20b parameters.
I am preparing for launch, the builds are not ready yet, but if you want to try, you can compile (Rust and npm tooling needed). Sources to nocodo will also be needed (https://github.com/brainless/nocodo).

I'm starting cold weather veggies indoors for my spring garden and preparing the soil.
I've been playing with various mineral amendments for years and produce some extremely tasty produce I have yet to see matched in stores (even the organic section).
(1) I've somewhat stumbled on a persona as a Fox-photographer who strongly communicates that he is a public affordance which (a) helps me get better photos of people, (b) gets me flagged down by people telling me about interesting things going on like
but having to reorder the cards I am planning on making a next generation card which has a unique chibi and unique QR code that will let me personalize the landing page for cards, particularly I will be able to share a photo just with the person who has the card.
============
(2) I've been doing heart rate variability biofeedback experiments and I have this demo
It works with most heart rate monitors that support the standard BTLE API not just the H10. I run it on the Windows desktop with Chrome and with Bluefy on iPad. Once it displays the instantaneous heart rate I can control
by following the slope of the instantaneous heart rate, breathing out when it is slowing down and breathing in when it is speeding up. This greatly intensifies the Mayer_wave and increases the SD1 metric. I think this drops my blood pressure significantly when I'm doing it. This needs better instructions and some kind of auditory cue so I can entrain my breathing when I am looking at something else. Longer term I am interested in incorporating some other biofeedback gadgets I have like a respiration monitor (got an abdomen band and a radar which could probably even read HRV if I had the right software for it) and a GSR sensor, and EMG sensor, etc.
I'm building Dropnote, a small tool for physical businesses.
Someone who is physically at a place can scan a QR code and leave a short message in their browser. No app, no account. Messages are asynchronous; staff reply when available. This is not live chat. It's meant for in-the-moment feedback or questions that don't justify interrupting staff or becoming public reviews.
Constraints: async only, anonymous by default, no customer tracking, messages tied to specific physical spots
Free early access until Sept 30, 2026 (+ one extra free month). No credit cards (no payments yet). I'd love to hear your Feedback. Thank you.
Web based mapping and navigation application that basically does everything all the other products don't do. Raceline analysis, driving aids, Dakar rally, CANBUS, OBD, Nightrider for race cars? or something. Passion project whatever. Investors get lost.
It's a creative project in which I add a new room to a mega-dungeon over the course of a year, resulting in 12 levels and approximately 30 rooms per level at the end. All the tiles are created by me using my own tools. It's a lot of fun and something I can do every day that I feel like I can enjoy for a year.
It's focused on OSR/Shadowrun. It's also taught me a lot about dungeon design and creation.
Fetching every church from IRS data; using a small local Mac mini LLM to match to their Google result, fetching site and (eventually) running a data enrichment LLM pass to determine various positions, metadata, and services offered. I just really wanted to see the data in aggregate. My current match rate is 30% with qwen2.5-14b. Doing my best to avoid spending a lot of $ on the processing even if the Mac mini is slow.
Stretch goal: start transcribing sermons (most churches link to videos) and using a LLM pass to look for toxic traits. Speak truth to power about how a lot of them turn a blind eye to this political moment.
I love this idea. I love that you're using these new tools to do what would essentially be weeks/months of work by a small team of people. Elaborate on "toxic traits" and "Speak truth to power about how a lot of them turn a blind eye to this political moment." please. No judgement, I promise.
Thanks for your support! I am happy to embrace LLMs to tackle a difficult problem without a team or funding too.
Toxic traits: Prosperity gospel, politics from the pulpit (explicit party affiliation/candidate endorsement - I've unfortunately been to a church that asked the audience to clap for Elon musk's DOGE stuff in service, cringe), celebrity pastor (can be indicated by people asking audience to clap for pastor excessively, like every Sunday), some of the NAR/Bethel type stuff.
I welcome any thoughts, sometimes my motivation comes from my own church hurt, and I'd like any future client of this data to reflect broader needs and not just my own frustration.
Verimu - we're trying to help medium and small businesses across the EU get up to speed with the new Cyber Resiliance Act requirements (which start in September!) trying to make it as frictionless as possible - drop in a github action and you are good to go. Web based dashboard coming soon!
I'm working on a sewing pattern software to make patterns with code. It has a bunch of useful features like chopping up the pattern into a PDF for printing. But the thing that really made this software nice to use is the timeline I implemented, where you can go back and see how the pattern is constructed with each segment. It makes debugging so much easier. I have it so you can put different curves into groups, so you can see how just the sleeve is constructed, for example.
I will definitely consider adding timelines to future software I make, it's an awesome feature.
The State of Utopia[1] is currently fine-tuning an older 1 GB model called Bitnet, so that we have something beginning to have the shape of a sovereign model that can run on the edge. We think having model sovereignty is important for our citizens, and we are working on tools for them to easily further fine-tune the model straight from their browser. We are currently running a 30-hour training run on some simple hardware and through webGPU, so that no trust or installation is required.
We made it possible to run the model in webGPU and it is pretty fast even in that environment. You can see the porting process in my last few submissions, because we livestreamed Claude Code porting the base model from the original C++ and Python.
In a separate initiative, we produced a new hash function with AI - however, although it is novel, it might not be novel enough for publication and it's unclear whether we can publish it. It has several innovations compared to other hash formats.
We are running some other developments and experiments, but don't want to promise more than we can deliver in a working state, so for more information you just have to keep checking stateofutopia.com (or stofut.com for short).
Our biggest challenge at the moment is managing Claude's use of context and versions, while working on live production installs.
Everything takes time and attention and Claude Code is far from being fully autonomous building new productive services on a server - it's not even close to being able to do that autonomously. We feel that we have to be in the loop for everything.
[1] eventual goal: technocratic utopia, will be available at stateofutopia.com
Like a lot of others, I'm working on replacing apps that I use that aren't just perfect for me. So I've been working on a local "Hey.com" replacement that lets me have multiple "feeds", real search and offline use.
I've been working on a deep seabed simulation, specifically to simulate polymetallic nodules for cobalt/nickel mining in Project Chrono. Development has stalled as I scan my nodule samples to enter them into the simulation (half of my samples were stolen from my porch, which delayed things), although the sim works just fine. The idea is you could take what I have now and, in project chrono, load a vehicle and test deep sea nodule mining using different designs.
It comes with a rigid (fast but wholly inaccurate) simulation, as well as DEM (which will make you cry and want to build a new computer). Having lots of fast cache helps with the DEM sim
Funding for https://infinite-food.com/ - seeking $100M - now finalizing four strong patents in the non-military drone space. Had a couple of false start time wasting lawyers, but now it's home run time. We've got what seems to be a few simultaneous nice technical edges over the multibillion dollar investments in civilian aerial delivery of food from major early stage players to date. Can't wait to close, itching to get to market and start generating some proper California lunch money.
Simultaneously, working on some technical demonstration materials, including novel fabrication and supply chain, plus some reduced BOM strategies for greater efficiency in mass manufacturing (once we get cash over the line). Bit of electronics in there, some mechanical. Keeps me interested so it's not 100% admin.
Also getting back in to badminton, super fun, losing weight nicely, feeling better every week.
New ideas? AI government will have its day in our lifetime.
Chess67 is a platform for chess coaches, clubs and tournament organizers to manage their operations in one place. It handles registrations, payments, scheduling, rosters, lessons, memberships, and tournament files (TRF/DBF) while cutting out the usual mix of spreadsheets and scattered tools. Iām focused on solving the practical workflow problems coaches deal with every day and making it easier for local chess communities to run events smoothly.
I'm currently unemployed and I started using Codex a couple of weeks ago so lot's of simultaneous projects, some stalled
Pre-codex:
Local card game: there's a very specific card game played in my country, there's online game rooms, but I want to get something like lichess.org or chess.com scale, oriented towards competitive play, with ELO (instead of social aspects), ideally I would get thousands of users and use it as a portfolio piece while making it open source.
cafetren.com.ar: Screen product for coffee shops near train stations with real time train data.
Post-codex:
SilverLetterai.com: Retook a project for an autonomous sales LLM assistant, building a semi-fake store to showcase the product (I can fulfill orders if they come by dropshipping), but I also have a friend and family order which I should do after this. 2 or 3 years late to the party, but there's probably a lot of work in this space for years to come.
Retook Chess Engine development, got unstuck by letting the agent do the boring busywork, I wish I would have done it without, but I don't have the greatest work ethic, hopefully one day I will manually code it.
Finally, like everyone else, I'm not quite 100% content with the coding agents, so I'm trying to build my own. Yet another coding agent thingy. But tbf this is more for myself than as a product. If it gets released it's as-is do what you want with it.
I'm learning about "AI programming" by working on some toy problems, like an automated subtitle translator tool that can take both the existing English subtitles and a centre-weighted mono audio extracted from the video file and feed it to an AI.
My big takeaway lesson from this is that the APIs are clumsy, the frameworks are very rough, and we're still very much in the territory of having to roll your own bespoke solutions for everything instead of the whole thing "just working". For example:
Large file uploads are very inconsistent between providers. You get fun issues like a completed file upload being unusable because there's an extra "processing" step that you have to poll-wait for. (Surprise!)
The vendors all expose a "list models" API, none of which return a consistent and useful list of metadata.
Automatic context caching isn't.
Multi-modal inputs are still very "early days". Models are terrible at mixed-language input, multiple speakers, and also get confused by background noises, music, and singing.
You can tell an AI to translate the subtitles to language 'X', and it will.. most of the time. If you provide audio, it'll get confused and think that it is being asked to transcribe it! It'll return new English subtitles sometimes.
JSON schemas are a hint, not a constraint with some providers.
Some providers *cough*oogle*cough* don't support all JSON Schema constructs, so you can't safely use their API with arbitrary input types.
If you ask for a whole JSON document back, you'll get timeout errors.
If you stream your results, you have to handle reassembly and parsing yourself, the frameworks don't handle this scenario well yet.
You'd think a JSON list (JSONL) schema would be perfect for this scenario, but they're explicitly not supported by some providers!
Speaking of failures, you also get refusals and other undocumented errors you'll only discover in production. If you're maintaining a history or sliding window of context, you have to carefully maintain snapshots so you can roll back and retry. With most APIs you don't even know if the error was a temporary or permanent condition, of if your retry loop is eating into your budget or not.
Context size management is extra fun now that none of the mainstream models provide their tokenizer to use offline. Sometimes the input will fit into the context, sometimes it won't. You have to back off and retry with various heuristics that are problem-specific.
Ironically, the APIs are so new and undergoing so much churn that the AI models know nothing about them. And anyway, how could they? None of them are properly documented! Google just rewrote everything into the new "GenAI" SDK and OpenAI has a "Responses" API which is different from their "Chat" API... I don't know how. It just is.
Microplastics are bad. People are concerned that there are microplastics in your balls! And that this could epigenetically affect downstream generations. I want to test that theory with a real human, not an animal model.
My plan: collect my own sperm samples over time and do whole DNA preps + basic body metrics. Sperm regenerates approximately every 10w, so planning time series over 10w. Next, inject myself to ~10x the average amount of microplastics, directly into the bloodstream. Continue with the sperm collection, DNA preps, and basic body metrics. Nanopore sequence, and see if there actually ARE any epigenetic changes. Eventually I'll go back down to baseline - are there any lasting changes?
Of course, this is an N=1 experiment, but rather than a metastudy I'm directly changing one variable, so I think it is valuable. We should have more people doing controlled experiments on themselves for the sake of all of society - and as a biologist, I actually have the capacity to design the experiments and scientifically interpret the results. In a way, it's part of civic duty :)
This remains uncontrolled and unblinded experiment complicating the interpretation of the results. For instance, can you be sure that any changes you might see are not caused by (e.g., hormonal, behavioural) changes induced by your knowledge that you just received 10x the average amount of microplastics?
if 10x the average amount of microplastics are showing changes that are approximately equivalent to hormonal or behavioral changes, it's not a significant factor to be worried about.
There are many times where unblinded experiments are still valid. And unfortunately, n=1 means that you can't have controls. The question: "did this intervention, in one person, cause a greater-than-normal increase in epigenetic changes, above baseline?"
I was just listening to something the other day about how there is essentially no way to study this right now, and the most common method of microplastic detection in samples has been proven largely inaccurate.
Is there some reason we think microplastics are more dangerous than the other nanoparticles of inorganic dust we consume and inhale every day? Serious question - Iāve got enough to worry about and this seemsā¦ very low on that list?
Please don't. The fact of this being a sample size of 1 and not being taken seriously because of that should be enough reason not to try it, let alone the health risks. I'm sure there are safer tests you could do.
I am a DevOps engineer with a background in AI. I think OpenClaw is the best that happened to us, giving some power from the well funded AI companies back to the community. I think it's the new kind of Linux and it's exciting to me to witness its early days
I'm building DB Pro, a cross-platform database management app that lets you browse, query, and manage SQLite, PostgreSQL, MySQL, Redis, MongoDB, and more from a single native interface. It's been growing steadily with a community of ~1,400 subscribers on YouTube and paying users.
What I'm most excited about right now is DB Pro Studio: a collaborative web-based version I'm building on top of it.
The idea is simple: databases are a team activity, but every DB tool treats them as a single-player experience. Studio adds either a self-hosted or managed hosted data browser, real-time collaboration, dashboards, visual workflow automation, and enterprise features like audit logging and role-based access. Think "database command center" where your whole team can inspect, query, and build on your data together.
The desktop app acts as the execution engine (your data never leaves your infrastructure), while Studio provides the shared dashboard layer.
I've also consistently posted devlogs on YT throughout the journey, which has helped build a community of ~1,400 subscribers who've shaped the product along the way.
Site: https://dbpro.app YouTube: https://youtube.com/@dbproapp
Would love feedback from anyone who's felt the pain of sharing database context across a team.
It's fascinating to me that people are still making money on RDBMS UIs in 2026. Maybe there's hope for my markdown notes app after all?
I like the way you have the detailed roadmap of features for each version. It's nice for the user to feel connected to development like that.
I find that when people can see what's coming, they're more invested in the product and more likely to share feedback that actually shapes the direction. The devlogs on YouTube serve the same purpose. It's a two-way street.
I've always wanted to build one of these! This looks like great work, and I like the team-oriented premise.
Thanks Steve! The team angle came from mine and my co-founder's own frustration. We kept copy-pasting query snippets and results of queries into Slack/Teams to our engineering team but also Sales/Marketing etc. Figured there had to be a better way. If you ever want to give it a spin, I'd love to hear your thoughts.
I'm a solo dev building a handful of apps across different niches..
- Kvile ( https://kvile.app ) ā A lightweight desktop HTTP client built with Rust + Tauri. Native .http file support (JetBrains/VS Code/Kulala compatible), Monaco editor, JS pre/post scripts, SQLite-backed history. Sub-second startup. MIT licensed, no cloud, your requests stay on your machine. Think Postman without the bloat and login walls.
- Mockingjay ( https://apps.apple.com/us/app/mockingjay-secure-recorder/id6... ) ā iOS app that records video and streams AES-256-GCM encrypted chunks to your Google Drive in real-time. By the time someone takes your phone, the footage is already safe in the cloud. Built for journalists, activists, and anyone who needs tamper-proof evidence. Features a duress PIN that wipes local keys while preserving cloud backups, and a fake sleep mode that makes the phone look powered off during recording.
- Stao ( https://stao.app ) ā A simple sit/stand reminder for standing desk users. Runs in the system tray, tracks your streaks, zero setup. Available on macOS, Windows, Linux, iOS, and Android.
- MyVisualRoutine ( https://myvisualroutine.com ) ā This one is personal. I have three kids, two with severe disabilities. Visual schedules (laminated cards, velcro boards) are a lifeline for non-verbal children, but they're a nightmare to manage and they don't leave the house. So I built an app that lets you create a full visual routine in about 20 seconds and take it anywhere. Choice boards, First/Then boards, day plans, 50+ preloaded activities, works fully offline. Free tier is genuinely usable. Available on iOS and Android.
Love this! Had the same idea as Mockingjay for emergency situations where you donāt have time to upload, e.g. robberies, attacks, etcā¦ will give it a try!
Really neat! Also as a Linux user, I deeply appreciate the linux support :-)
A few questions and comments:
| Kvile |
- Awesome, really happy to see a reasonable take on this (open source, offline-first, no telemetry, no acount, etc). Do you think at some point you'll try to monetize it in some way?
- Looks like build assets didn't get attached for the latest release (v0.2.1) in Github: https://github.com/tskulbru/kvile/releases/tag/kvile-v0.2.1
| Mockingjay |
- Awesome, definitely a valuable project. I'll be sharing this with some friends who could really use this.
| Stao |
- The website says it's open source, but I couldn't find a link to the source repo. I looked at your github repos and didn't see it in there either.
- Great idea! I'm so bad about forgetting to stand so something like this could be super useful.
Kvile: Thanks for letting me know! havent noticed, since i mostly just use it myself. Will get it fixed!
Stao: Hm yea this is a mistake on my LLM when it generated the website for me (i couldnt be bothered). It probably got confused since i released it for Linux. Its not open-source. Yes! Exactly, thats why i made it, i ALWAYS forgot. I still do, but far less frequently than before, using Stao helped me a lot.
> MyVisualRoutine ...
> All apps i found were either shit, real shit, or didnt solve my personal need.
Wow, what an amazing coincidence. I made something that looks pretty similar from the looks of it just a few weeks ago because I found the same thing. If I knew your app existed I probably wouldn't have made it. I wasn't even thinking of selling it, just made it for my kid because it makes following various daily routines easier.
It's a mostly vibe coded (well, I made tons of visual and technical decisions but didn't look at the code much except some spot checks) PWA that can run offline on an iPod Touch.
It has some quirks and hidden features for day schedules, timers, etc.
There's plenty of yank in there (yours is almost certainly built better) but it works pretty well for most daily routines.
You can check it out here: https://girls-routine-planner.huppie.nl/
I love the idea behind MyVisualRoutine as a father with a disabled kiddo, thanks for sharing.
The app is beautiful - much better than I could build - what tech is it using if you don't mind me asking? Is it flutter, react native, something else? Just want to get better at mobile dev.
Thank you so much! Then you know my pain. All apps i found were either shit, real shit, or didnt solve my personal need. Hopefully this might help others the way it did for our family. The app is built using flutter because im going to release it on Android too very soon, and I couldnt be bothered creating it twice. Initially the idea was more of a game-like-app, and then it made sense to use flutter. Now though, its not really game-like and couldve just as well been native (apart for me not bothering doing it twice). If i wouldve done it again from scratch, for this app, i would still have chosen flutter.
> and a fake sleep mode that makes the phone look powered off during recording.
That's going to be used for recording women in public.
there's a line between functionality that can be abused and that which is very likely; the author is obviously on the former side of this line so you can take your crusade somewhere it could be useful.
Exactly, you basically said what I was going to say.
I'm not on a crusade. I'm telling you what it's likely to be used for in case you didn't think of it yourself. Pointing out that it's likely to be used for nefarious purposes is not equivalent of making an argument that it shouldn't exist.
I can appreciate that it's useful for journalism while also warning you that not every user is going to be a journalist. It's possible to have a conversation without being in a fight all the time.
I'm still working on my Web Server Library .NET Core, the rewrite is almost finished (beta version)

I've been working with my wife on Uruky [1] for a couple of months, now. It's a EU-based Kagi [2] alternative (privacy-focused and ad-free search with domain boosting/exclusion rules).
We've been using it with friends and family semi-successfully (hashbangs work for edge cases we're still working on).
It's really difficult to get bigger indexes other than Mojeek and Marginalia to want to work with us and improve the results further, so that's something I've been researching more, lately. EUSP (the new Ecosia/Qwant-effort-related index) has finally replied to me last week, but I'm still waiting on an API key.
If you're interested in trying it for a few days and are a human, reach out with your account number and I'll give you a couple of weeks for free. We're pushing improvements daily.

P. S. It's weird to see this duplicate (posted less than a week ago in https://news.ycombinator.com/item?id=46874385), but this post has a lot more comments!
Eventual source code access is an interesting idea. What language is Uruky implemented in?
Thanks! It's intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such), using Deno in the backend and PostgreSQL for the DB.
My friend and I have been working on https://www.vespper.com its essentially an ai-native word editor for long-form content.
it comes with a suite of tools (multi-agent tools to do search over many docs, RAG out of the box, prompt generation per section to reduce context drift, granular AI steerability, structured block generations for 100+ page reports ect.)
EACL: Enterprise Access ControL is a situated ReBAC Authorization system based on SpiceDB, built in Clojure and backed by Datomic ā https://github.com/theronic/eacl
'Situated' here means that your permission schema & permission data live with your data, which has a number of benefits:
- one less network hop, so can be faster than Spice for typical workloads,
- one less distributed consistency & syncing problem,
- one less component to run in prod with full consistency,
- potential to implement ZedToken / Zookies via Datomix txid, and
- easy to test new schemas with in-memory Datomic.
EACL is plenty fast without a cache since horizontally-scalable Datomic Peers already cache datoms aggressively, but there is another 10-100x improvement in the pipeline. EACL is especially suitable to real-time multiplayer apps built in frameworks like Electric Clojure.
IMHO, EACL is currently the best-in-class authorization library in the Clojure ecosystem and is improving every week. ReBAC subsumes both ABAC & RBAC. I recently applied for Clojurists Together funding to improve cursors for intermediate resource traversal, which is the primary perf. bottleneck.
EACL was not "vibecoded" as all tests were written by me and all code is human-reviewed, but EACL would not be possible for a single engineer to build mainly in his spare time without AI assistance.

I built a TUI sampler which cherry-picks my favourite features from modern & vintage hardware samplers, DAWs, plugins, outboard FX gear, and DJ equipment.
If you know what an AKAI MPC Live, MPC 3000, SP404, SP1200, BOSS RC-202, Alesis 3630, Serato Sample, S950 filters, and stem separation does, then you'll love seeing these "greatest hits" up in a terminal interface.
Last year while on vacation in Costa Rica, I started scratching my own itch for locating and organizing samples, which quickly evolved into adding more and more features while keeping it tactile and immediate. It was too fun to stop so I kept going. After a few days I was happily making beats in it, and since then it's only gotten better.
It's live and totally free to use, and works in macos & Linux (Windows soon). I'm about to launch v1.0 now, just working with folks in the community to round out the Factory Kits a little more for users new to beatmaking.
Turns out, making beats with no mouse and a terminal interface strikes the perfect balance of hardware feel and software power, and I'm loving the result. Been sharing it with folks in my beatmaking sphere and have plans to continue expanding its reach through more collaborations, contests, and in-person events.
Hope it brings you as much joy as it does to me :)
I love working on the terminal and this looks great, but can I ask why do you require to sign in? To be that's a bit of a downer :(
totally fair point! the medium/long-term roadmap is to layer in a BBS-esque community, so identity is required. more on this later! regardless, might be nice to have an unauthenticated / "Skip sign in" flow for the folks who just want to use the tool.
Was this previously open source? There's a broken link to a repo at the bottom of the marketing page that results in a 404.
it was not, so that's a mistake that's been fixed, thanks!
Looks very promising! Unfortunately Docs and GitHub repo donāt work
apologies, those broken links are misleading (docs coming soon, but not open source atm). Removed.
Is this based on Bubbletea TUI framework? The waveforms are pretty cool!
Great intro video!
This is sick, great job!
TUI triggered me, so I had to take a look... It appears the GitHub link on your landing page is 404?
Very cool!

Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics: https://circuitscript.net/. A basic IDE (called the Bench) to try Circuitscript is available online: https://bench.circuitscript.net/
I have created a usb-uart converter board with the CH340 chip. The complete schematic was coded with Circuitscript and then imported as a netlist into kicad pcbnew to do the pcb layout. The design was produced with JLCPCB and after receiving the boards I tested them and they do work! The design files are here https://github.com/liu3hao/usb-uart-bridge. The circuitscript code file is here https://raw.githubusercontent.com/liu3hao/usb-uart-bridge/re... and the generated pdf from the circuitscript code is here: https://github.com/liu3hao/usb-uart-bridge/blob/main/usb_uar...
The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) for work in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.
Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!
This looks awesome, great job.
How effective at circuit generation are LLM's with the language? I tried similar, and could get syntactically correct files, but the content always had errors: https://www.mikeayles.com/#tokn
What are your thoughts on atopile and tscircuit?
This looks genuinely useful to my work. Is there a way to reach out for feedback?
I'm working on https://laboratory.love
Laboratory.love lets you fund independent plastic chemical lab testing of the specific foods you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kidās snacks, or whatever youāre curious about.
Find a product (or suggest one), contribute to its testing fund, and get full lab results when testing completes. If a product doesnāt reach its goal within 365 days, youāre automatically refunded. All results are published publicly.
This project was inspired by Nat Friedman's PlasticList.org and we use the same ISO 17025-accredited methodology they did, testing three separate production lots per product (when possible) and detecting down to parts-per-billion. The entire protocol is open.
I just published new results today! Turns out Muir Glen's caned Fire Roasted Diced Tomatoes are incredibly low in plastic chemicals. Yay!
Browse funded tests, propose your own, or just follow along: https://laboratory.love
https://github.com/jsattler/BetterCapture
It's a lightweight screen recorder for macOS that lives in your menu bar. It's built with SwiftUI and ScreenCaptureKit, uses the native Content Picker to select what you record, and supports ProRes 422/4444, HEVC, and H.264 ā including alpha channel and HDR. Frame rates from 24 to 120fps. System audio and mic simultaneously. You can also exclude specific things from recordings, like the menu bar, dock, or wallpaper.
No tracking, no analytics, no cloud uploads, no account. MIT licensed. Everything stays on your Mac.
Looks really sharp! I've been on the lookout for a new screen cap tool for Mac and this looks great, bookmarked.
Thanks, really appreciate the feedback!
A Jellyfin music client for Linux written in Rust and GTK:
https://github.com/Fingel/gelly
I thought it would be pretty simple, but here I am almost 6 months later still adding features. The positive feedback has been nice, though! People seem to appreciate (like I do) that its fast and doesn't use Electron or some other cross platform toolkit. Learning a lot.
It's not vibe coded. Sad that I have to make that qualification these days, but here we are.
Very nice, ran well in a VM on my home NAS.
I've always noodled about this marketplace idea where an optimization algorithm could match your interests and a dollar amount you can afford to let you rent/buy artist's music. The optimization would maximize the purchase of the differently valued music(analogus to the weighted knapsack problem but this could have multiple solutions, knapsack is a nice way of thinking about it logically, in reality implementation may be completely different) based only on your interests, like history and dollars u have. I am wondering how might one apply a distributed systems approach without having music pirated and shotgunned all across the internet? Like how would you quickly match a person to all the available music metadata? How would you model for interest matching if the music library is spread out across multiple nodes.
I would imagine a lot of people are ok with paying 5-10$ a month instead of 15-20$ for music they like from a set of artists they like.
I think you can still make the distinction of vibe coded vs using LLM for specific things(like review your code and write tests).
Vibe coding signifies a lack of control over one's own code and generally only if it's to generate ideas or throwaway. The negative connotation that goes with it is appropriate too.
In reality any project that takes 6 months means your have invested a lot of time thinking about the code, in which case LLMs become more useful for the things you care about e.g. maintainability, forcing LLMs to bend to your will, which is like saying: " I know this design is the best so just make this instead of whatever abstraction you think is better".
Yes to be clear what I meant was that itās not a prompt engineered project. I actually, for the most part, understand the code Iāve written :p
I have used LLMs to understand certain concepts and unfamiliar APIs. Gtk and Rust is actually a pretty funky combo.
Nice, thanks! Iāve been looking for a decent alternative to PlexAmp for Jellyfin.
Looks incredible, well done
Does GTK work for your use case therein? Does the documentation work for you?
This is pretty darn awesome. I havenāt checked it out yet, but Iām already psyched about it.
This is awesome, gonna check it out. Thanks! Helpful to look at a big rust project too as Iām learning rust.
This is cool but who owns music collection these days?
Definitely more common to just use streaming services like Spotify, but some people do own their music library. Thereās probably a decent sized overlap of those who buy music and those who self host things like jellyfin
I do, I buy albums on Bandcamp, rip my CDs, and as a last report buy MP3s on Amazon, which are surprisingly DRM free.
curious about not vibe coded, is it because you wanted to learn? or some thing else as well?
Maybe they care about it being robust in the long run, maintainable, secure and/or not too bloated.
Pretty much. I plan on using this program for a long time. I donāt want a codebase that looks like something out of a H.P. Lovecraft novel when I have to fix something in the future.
Here's an analysis of your codebase by Claude Opus 4.6 and Kimi 2.5 -- I don't code in Rust or GTK so I can't vouch for how spot on this is but I hope it's not too far off the mark and helps you improve your code. (Claude is wrapping both analyses together.)
Are you serious? You donāt think Iām capable of running the codebase through an LLM? Or is this supposed to be some kind of gotchya? Rude and lame.
I'm not the OP.
Not everyone is paying for LLMs, even now. So I think it is perfectly reasonable to assume good intentions, here.
Someone spent their own tokens to ponder your code and thought they'd share the result. For anyone else looking, like me, I can see that this is probably going to come up relatively clean without having to spend my own tokens, or install it, and I'm more likely to, now that I can see that.
Turns out it was bad intentions, I respect the optimism though. And thanks for taking a look!
Oh I'm ever so sorry -- because of course "I donāt want a codebase that looks like something out of a H.P. Lovecraft novel when I have to fix something in the future." is not at all rude and lame and you write perfect non-Lovecraftian code all day every day ā¦
Am I reading this correctly? You got offended on behalf of LLMs because of some quip I made about how I choose to write code on my spare time?
This is fascinatingly psychotic - but for your own good you might want to shut down the agents for a bit and take a walk.
Ignore them. These people are insane, don't ruin your day reading their messages.
https://instagit.com
Iāve been shipping AI-written code for 2 years now. I can build something amazing in 40 mins but then spend 4+ hours debugging because the agent has no idea how the libraries itās calling actually work. Docs are stale, StackOverflow is dead, training data is outdated. Every engineer I talk to has the same problem.
So I built Instagit, an MCP server that lets your coding agent understand any GitHub repo in depth so it can get it right on the first try. Works with Claude Code, Codex, Cursor, OpenClaw, etc.
No API key or account needed to try it out. Just need to share these instructions with your coding agent to get started:
curl -s https://instagit.com/install.md
Interesting! How does it work under the hood? If you can share. Would like to understand if this improves my Claude Code's understanding of my codebase.
Itās basically scanning the source code for each question (you can also check out specific branches or release tags if you need to debug a particular version) and then writes up the answer once it finds it.
Itās not really meant to query your own code base (Claude Code already does a great job at that) but more to explore other code bases you want to integrate with.
hey irrelevant question, what tools you use to make such great landing pages for your products? your instagit.com looks great, what's your vibe coding workflow?
Thanks! No fancy tooling, I made it by just prompting Claude Code with the "frontend-design" skill from Anthropic: https://skillsmp.com/skills/anthropics-skills-skills-fronten...
Any promoting tips for this sort of result?
Sure, here are a few tips:
- Use a static website generator (I use Astro but there are others) where the agent can fully control every aspect of the website
- Use skills to enhance the prompting, like this frontend-design one but can also combine it with copy writing/seo skills etc
- Give the agent control access to the browser to give it visibility into the result in order to iteratively improve upon it
- The last thing is to just be very demanding and setting a high bar, so ask for animations and ask the agent over and over again āok and now letās improve what you just didā
Thanks, yeah - astro is amazing. Itās too bad many people and llms reach for nextjs by default.
Why not context 7?
Context7 is great but ultimately itās just a pre-generated static summarization that might not include the specific answers the agent needs. I have a slightly different approach where the actual source code is scanned for each question so itās much more targeted and never out of date.
Iām building datenba.ch, a hyper-local ādigital villageā for a few small communities in rural Germany (Neckartal/Odenwald-ish).
Instead of another social network, itās a bundle of small, practical community tools under one umbrella, combining of the shelf-software with purpose-built projects of our own.
Our current areas of focus are
- help! a neighbor-to-neighbor help board (rides, errands, PC help, garden/handwork)
- hubs! for shared spaces / tool-sharing / events / social hubs
Right now Iām building the integration surface (claims, roles, provisioning), polishing onboarding, and trying to design help!/hubs! so theyāre useful even with low activity.
If anyoneās done (hyper-)local community platforms: Iād love to hear what actually drove adoption and what did not work out for you.
I built a PokƩdex for zoo trips for my girlfriend:
https://www.zookeeperapp.com
https://www.mikeayles.com/#zookeeper-wip
It lets you take photos of all the animals you see to collect them, when you 'capture' a new animal, it gives you fun facts about them.
I seeded it with UK zoos, but there's no reason it can't work elsewhere.
It was built because the signage at a zoo we went to was terrible and we had no idea what some animals were, so it matches your photo with the list of animals to the best of its ability.
That's a lovely idea! I wanted to build something similar for safaris but the lack of network in remote areas makes it a bit tricky to use online image recognition models. I never went down the rabbit hole to use offline ones.
I built a CLI tool in rust to find and remove duplicate files.
At work I sometimes download the same file multiple times to my machine and have to go through my downloads folder and manually remove the duplicates, so this is something I built to speed up the process of doing this.
https://github.com/jconvery1/hydra
I've found it quite useful.
I built a CLI years ago for the same purpose.
From what I can tell, your program treats files as duplicates if they share the same normalized filename and the exact same size; it doesnāt compare contents or hashes.
Mine samples bytes at specific positions, hashes those samples, and compares the hashes to produce a similarity score rather than a strict match. This works great for photos, two shots taken in the same second can differ slightly in pixels but still depict the same scene, so theyāre considered duplicates. It also normalizes image orientation by rotating based on the brightest corner, so photos in different orientations are compared using the same features.
https://concludia.org/ - I've mentioned it here before, it's a site to help people reason through and understand arguments together. No real business purpose for it yet, it's more an idea I've had for years and have been wanting to see it through to something actually usable. You can graphically explore arguments, track their logical sufficiency/necessity, and make counterpoints. It's different than other types of argument theory that just have points "in favor" and "against" because of how it tries to propagate logical truth and provability.
Iāve had a concept like this in the back of my mind for years. Happy to see someone executing it so well.
For me, it started when I spent a year and a half reading and digesting books for and against young earth creationism, then eventually for Christianity itself (its historical truth claims). It struck me that the books were just a serialization of some knowledge structure that existed in the authorsā heads, and by reading I was trying to recreate that structure in my own head. And thatās a super inefficient way to go about this business. So there must be a shortcut, some more powerful intermediate representation than just text (text is too general and powerful, and you canāt compute over itā¦ until now with LLMs?)
That graph felt a lot like code to me: thereās no unique representation of knowledge in a graph, but there are some that are much more useful than others; building a well-factored graph takes time and taste; graphs are composable and reusable in a way that feels like it could help you discover layers of abstraction in your arguments.
Yes - currently, each argument/graph is independent, but I've designed it in a way that should be compatible with future plans to "transclude" parts of other public graphs. Like if some lemma is really valuable to your own unrelated argument, being able to include it.
I do think there's quite a lot that could be done with LLM assistance here, like finding "duplicate" candidates; statements with the same semantic meaning, for potential merge. It's really complicated to think through side effects though so I'm going slow. :)
We would have saved so many wasted hours in the last company I worked for if we had this... you have no idea, to give you a sense, the decision to move from a Neo4J db to MySQL (the service was failing, the DB was failing, it was a bad architecture decision) took 6 months, when it should have been at most a couple days discussion.
Nurture this, it will become a great tool in the belt for a lot of people
Do you mind me asking, what kind of problems did you run into with Neo4j? Did you encounter performance issues after the DB grew to a certain size, or did you realize that the data wasn't suited to a graph DB and weird query patterns started causing trouble, or was it something else entirely?
I'm considering using a Neo4j self hosted instance for a project, but having only played around with it in low-stakes + small-data toy projects, I'm not really familiar with the footguns and failure modes...
All that aside, plugging holes in a sinking database for six months because you can't come to a descision does not sound like a fun time :D
This is pretty cool! I'm not sure how you'd make a business out of it, but I can definitely see myself using it to justify some decisions on my day to day stuff.
I'm also a sucker for serif fonts so points for that.
I wanted to add more value to this comment about monetisation - regardless if that's doable or not, it's an extremely cool project!!
What if you could sell the data for each argument? That might be valuable to LLM labs, because then you can essentially guarantee that every single argument you provide is human checked, and you could accumulate a large DB of those. Of course you'll never be able to capture every single argument possible, but it's rather a mechanism that would allow incremental improvement with time. But codifying logic and natural language is a very nice idea.
Yeah, I only just yesterday got it to the point where people can create their own arguments. I was just using it to check my own assumptions on why I have such a complicated "end-of-month finances" list of things to do. :) But I also like the idea of using it for political arguments or even fun stuff like mystery-solving.
I like this. It reminds me of the interesting type of experimentation that was done with LLMs before agentic coding took over as the primary use case.
I am interested in seeing a personal version of this. Help people work out their own brain knots to make decision-making easier. I'm actually decent at mending fences with others. Put making decisions myself? Impossible.
You can actually register now (with a waiting list) and make your own private graphs, if that's what you meant by a personal version. (You'd be like member #4 haha)
I've actually had a lot of fun hooking it up to LLM. I have a private MCP server for it. The tools tell it how to read a concludia argument and validate it. It's what generated all the counterpoints for the "carbon offset" argument (https://concludia.org/step/9b8d443e-9a52-3006-8c2d-472406db7...) .
And yeah... when I've tried to fully justify my own conclusions that I was sure were correct... it's pretty humbling to realize how many assumptions we build into our own beliefs!
Cool idea, I think graphs (what youāre doing) are a better way of modeling arguments because it captures nuance often lost in 1 v 1 model of debate
Frustration at that kind of debate has been a large part of the motivation, how it occludes so much of what ideally should be a dialectic. I especially dislike how if someone gets flustered, they're seen as losing.
A tool for creating CSS color palettes for web UIs that pass WCAG accessibility standards for color contrast, where you can fine tweak all the tints/shades quickly using a hue/saturation/lightness curve editing interface:
https://www.inclusivecolors.com/
Unlike most tools based around autogenerating colors, this is more of an editor that lets you fully customise all the tint/shades to your liking with a focus on accessibility. This is important when you've got existing brand colors to include and want to find accessible color combinations that work together.
Would love feedback in general and especially from designers/devs who have different needs in how they go about creating branded palettes!
This is great! As a non-designer, I've been relying on ChatGPT to select color schemes/palettes for me.
> I've been relying on ChatGPT to select color schemes/palettes for me
Thanks! Any problems you've found with this approach or it's usually good enough?
For me, I couldn't find a tool that would let me customize multiple color scales at once, check they look good together on a mockup, and also be accessible. It's one of those problems where you can autogenerate something that gets you most of the way there, but then for it to be usable you need need to see how it looks on designs and fine tweak it.
Have you tried https://huetone.ardov.me/? Multiple color scales, P3, export to CSS and figma, as well as APCA & WCAG for accessibility.
So for my tool, I really need the live UI mockup without having to export first to tweak the colors until they work (e.g. often the off-white/very-light colors used for backgrounds are too vibrant otherwise), the control-point based curve editing helps to explore hue/saturation/lightness curves around a brand color without a lot of clicking, and I want the option for palettes where each color scale follows the same steps in lightness (for predictable contrast between steps from different color scales).
Barely any designers I work with know about P3 colors (feels like P3 mostly appeals to developers right now, for programmatic reasons?), so I'm not that interested in P3 if it means using OKLCH with its intimidating looking color picker. My tool uses HSLuv, which looks familiar like an HSL color picker, where unlike HSL only the lightness slider alters the WCAG contrast, so HSLuv (while limited to sRGB) is great for exploring accessible colors.
I've actually got support for APCA, but I find many struggle understanding WCAG contrast requirements already. There's Figma export too.
Anyway, there's lots of overlap between different color tools but the small details are important for different workflows and needs. I've started to realise too that most designers need a lot of introduction into building (accessible) color palettes in general so it's a tricky puzzle between adding features and trying to keep it simple, which is why I'm very open to suggestions!
I love making games, and Iāve been building a no-code game engine by extracting reusable components every time I ship a new game. It started as me scratching my own itch, and now itās turning into a real platform.
Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click. For game logic, I recently added a visual event system Iām really excited about. Itās kind of like Unreal Blueprints, but focused on 2D. You pick a trigger, wire conditions, and chain actions in a node graph [1].
Big challenge right now: most people who want to make games needs assets, and don't know how to get/make them. So Iām building a marketplace where pixel artists can upload tilesets/characters, and unlike itch.io, assets are usable directly inside the engine. No ZIP downloads or import setup, just browse and drop into your game. A preview here[2].
Also, if you want to use the editor but ship elsewhere, you can export terrain, animations, and hitboxes to Godot 4. Nothing is locked in.
The engine/editor is at https://craftmygame.com if anyone wants to poke around! And you can test a games here[3][4], and 1 multiplayer game I've tested IRL in a bar [4]!

I'm a web developer and getting very interested in making games but obvuiouly have 0 ideas about it.
Can you recommend any cause to make using Claude Code.
As a web dev you're in a better spot than you think ā state management, event handling, render loops... you already have the mental models.
Claude Code can genuinely help you with: - Scaffolding a game project (Phaser.js is great for web devs getting into 2D) - Writing boilerplate: input handling, collision detection, basic physics - Debugging weird edge cases in game logic - Generating utility code like sprite sheet parsers, tilemap loaders, etc.
What it can't do (and where most beginners hit a wall): - Game design. Knowing what makes a game actually fun is a skill Claude can't shortcut. You need to playtest, iterate, and develop taste. - Art and assets. This is the #1 blocker for most solo devs. Claude can't draw your sprites or design your tilesets. - Feel and polish. Tweaking jump curves, screen shake timing, hit feedback ā that's all manual iteration. AI will give you "technically correct" values that feel lifeless. - Architecture decisions. Claude will happily generate an ECS system or a scene manager, but it doesn't know your game's actual needs. Bad architecture early on will cost you weeks later.
Start with a tiny scope (like a single-screen platformer), use Claude Code to move fast on the code side, but spend most of your energy on the parts AI can't help with ā design and feel.
Also, shameless plug, if you want to skip the code entirely and just focus on making the game, that's what CraftMyGame is for. Everything is visual, no coding needed. Might be a good way to prototype ideas fast before deciding if you want to go deeper on the code side ;)
CraftMyGame can make something like retro street fighter(not need to be perfect) ? If it can, and allow me to export the code(I would like to add those game to some of the apps I'm planning), you'll get paying customer.
I've been working on the demo for Globs, a daily puzzle game about finding the hidden theme behind a jumble of tiles:
https://threeemojis.com/en-US/play/globs
It was inspired by 2025 by thomaswc, a 45x45 connections-like puzzle. Globs jumped off from there and it's been very fun to make. I have AI generating the puzzle groups and it keeps surprising me everyday with what it comes up with. I've got demos up for over 20 different languages, and many different sizes of puzzle. Just recently, I got the puzzle to be generated daily for American English, British English, High German and European Spanish. It can also do custom theme puzzles like the following:
Big YC https://threeemojis.com/en-US/play/globs/en-US/demo?size=big...
Jumbo HN https://threeemojis.com/en-US/play/globs/en-US/demo?size=jum...
There is still some bugs I am tracking down (open the page in a private browser if you hit stale data) but the game has really come together lately and been a lot of fun, I hope you all like it!
I built https://measuretocut.com after too many DIY projects ended with another trip to the hardware store. It figures out how much material you actually need and how to cut it to minimize waste or costs. When I released it in December it just handled 1D cuts for things like boards, bars, and pipes. You enter what you need, and it lays everything out visually on stock lengths. This morning I released the 2D sheet cut calculator to do cut plans for plywood and similar sheet materials. Any feedback is welcomed from fellow engineers turned woodworkers!

It's an infinite canvas that runs SQL.
I've been working with data my entire career. I feel like we need to alt+tab so much. What if we just put it all on a canvas?
Currently very WIP, but there's a simple titanic demo available!
Built with tldraw and duckdb wasm, running on cloudflare durable objects
Look at count.co for a Figma-like approach to databases.
We were using it at work (transitioning to Metabase); it's great for exploring and debugging and prototyping but it ends up too much of a tangled spaghetti mess for anything long-term. Would not recommend for user-/other-company-departments-facing reports or dashboards.
That's super interesting!
With Kavla I want to lean into the exploring/debugging phase for analytics. "Embrace the mess", in a way.
My vision is that there will be an "export to dbt" button when you're ready to standardize a dashboard.
What made you pick count? Was spaghetti the major reason you left count, or something else?
The choice to use Count was made before I joined the company; IIRC they migrated to it from Tableau.
We wanted to migrate (to Streamlit, back then) to have the SQL not live locked in a tool, but inside our git repository; to be able to run tests on the logic etc. But the spaghetti mess was felt too, even if it wasn't the main reason to switch.
(But then, 1) some team changes happened that pushed us towards Metabase, and 2) we found that Streamlit managed by Snowflake is quite costly, compute-time wise. (The compute server that starts when you open a Streamlit report, stays live for tens of minutes, which was unexpected to us.)
----
Export to DBT sounds great. Count has "export to SQL" which walks the graph of the cell dependencies and collects them into a CTE. I can imagine there being a way to export into a ZIP of SQL+YML files, with one SQL file per cell.
Thank you so much for sharing, super helpful!
Great take on the SQL lock in, that's something that I need to think hard about. Ideally a git integration maybe?
Kavla also traverses the DAG, psuedo code:
A selected chain of Kavla nodes could probably be turned into a single dbt model using CTEs!Thanks for making me think about this!
Somehow i had landed on your page sometime back and was just impressed with the quality of landing page and also the concept. Hope to use it in near time.
The website is great and the examples (like getting distinct values of a table as a prerequisite investigation) really get the point across.
In my job I always end up with big notebooks of data exploration that get messy fast and are hard to share anything but the final result, having a canvas that embraces the non-linear nature is a great idea.
That has been my experience as well!
Aside from the non-linearity, what key features would make you use Kavla instead of a notebook?
Love the brutalist style. Are the components all hand-rolled or something off the shelf?
I was inspired by https://www.neobrutalism.dev/ !
Looks very much like like a signature gemini ui.
Cool looking website! Is that an open source css library or did you style it yourself?
I was inspired by https://www.neobrutalism.dev/ !
it's so useful, specially to teach SQL, congrats, keep doing it!
as someone who loves sql and wants to transition into a DBA specialty from being more frontend, I am very inspired by this
Thank you!
What resource(s) are you using for learning SQL and DBA concepts?
I haven't really thought about Kavla as being a learning environment, maybe you are onto something!
Wow, this seems great for doing interviews with an analyst, or just demoing data generally. Cool product!
Interviewing is an interesting use case!
Is that something you're doing? What pain points do you have as interviewer with existing tools?
Nonna Emilia, so I don't forget people's names and what they're up to anymore.
I did post about Emilia a few months ago... now I have a domain https://meetemilia.com/
The basic idea is that you give Emilia knowledge about your family and friends, and then you can ask her questions or (eventually) get reminders.
I was motivated during an extended family gathering where I completely blanked out on the names of the partners of some of my cousins. I felt awful... trying to hide the fact that I didn't remember their names.
Now the names and who they are etc is there in Nonna Emilia, and through natural text I can ask questions like "what's the name of all the partners of my cousins on the side of my dad's family?" or something like that.
I am looking for alpha users. The service has legit helped me a few times already remembering stuff, but the amount of work to input all this data still bothers me.
Anyway, it's free. If you want go ahead and try (bugs here and there I bet, and you need a Google Account) and shoot me an email at inerte@gmail.com if you have any comment.
I am currently building an alethiometer from the phillip pullman book series: his dark materials
Specifically its a remake knowing what we know now having finished the two trilogies.
Instead of the three hands and the moving needle, its just one moving needle. Its made from wood and aluminium. The reason for aluminium is that in the 1920s (roughly the age that these books are set) is a wonder material, a bit like carbon fibre/titanium is now.
I have the working mechanism (controlled by 8mm steppers) I need to finish the case and dial, and paint it. I also need to shrink the controlling mechanism and design the voice->text->inference->output to 36 symbols logic.
I'm an embedded software engineer by day and like it or not I have to acknowledge that AI tooling is coming to our work, so I'm currently working on learning to interact with AI coding tools like Claude Code more effectively and efficiently by "vibe-coding" a game for a family member on my personal time. Something inspired by a blend of 'Recettear' and 'Stardew Valley' with the touch that the player shopkeeper is an anthropomorphic cat.
Sorcery - open source app and protocol that, together, let you share source code links that open in each user's favorite editor, right on the linked line.

AskUCP ā UCP protocol explorer showing all products on Shopify (https://askucp.com/)
On January 11th, Google and Shopify announced the Universal Commerce Protocol (ucp.dev). It's an open standard that lets any application query products across e-commerce platforms without needing APIs, integrations, or middlemen. AskUCP is one of the first applications built on it.
Right now, if you want to buy something online, you have to know which store sells it. You go to Amazon, or you go to a Shopify store, or you go to Etsy. Each one has its own search, its own interface, its own checkout. The experience is fragmented because the infrastructure is siloed.
UCP changes this at the protocol level. If products are described in a standard format, any application can discover them. You don't need permission from each platform. You don't need to build integrations. Anybody or any AI agent just querys the protocol.
AskUCP is designed to be a single pane of glass into online commerce. You search once, and you see products from across the ecosystem. Currently, that means the entire Shopify catalog. As more platforms adopt UCP, their products become explorable too. Eventually, it should be everything.
This is a proof of concept. It's early, and there are rough edges. Let me know what you think, refinements, ideas etc etc.
https://mealplannr.io
The end game is no/low touch weekly meal plans send directly to your inbox, with meals you love to cook but with none of the hassle around planning the meals, shopping list etc (which I spend hours doing every week).
An important feature for me was improving the recipe discovery experience, you can build a cookbook from chefs you follow on socials (youtube for now), or import from any source (Web, or take pic of cookbook etc) - it then hastight / easy integration into recipe lists.
Utilising GenAI to auto extract recipes, manage conversions, merge/categorise shopping lists etc - as-well as the actual recommendations engine.
If anyone is interested in beta testing / wants to have a chat I'll look out for replies, or message mealplannr@tomyeoman.dev
Humetrical ( https://humetrical.com ) -- A wellness platform that puts people's mental health first by showing work metrics that matter. Because burnout blindness leads to exit interviews.
It wasn't until we had a leadership retreat at my day job with a fantastic speaker (Woodrie Burich) that the idea for my platform spawned. She talked about how the $50B wellness industry is doing it wrong. Your company is giving you useless yoga stipends, when truth is they should be paying attention to your overall well being. One idea she presented that resonated with me was using a traffic light-like system to gauge where your employees are mentally at.
I took that to heart and verbally applied it to my team. Then I realized that a platform would give better visuals of the data and be easier to incorporate into everyone's day to day. A couple months later I finally released it.
Making improvements to https://engineering.fyi/ - an aggregator for big tech blogs
Added summaries so readers can quickly see if it's worth reading the entire article e.g. https://engineering.fyi/article/towards-self-driving-codebas...
In my spare time https://bookclub.cloud.
Itās a tool that leverages your drm free ebooks to help manage your book clubs. The epub file offers more rich info such as:
- word counts per reading
- chapter selection
- the ability to highlight sections and share
- ai summarization and spoiler free discussion about the contents of a given reading
I use it for my own book club right now. I doubt Iāll be able to monetize the app due to the need for drm free epubs which is a pretty high barrier for entry to most non-technical users.
My long term plans would be to have an agent help readers learn hand in hand while reading. Iād like to have the agent facilitate deeper analysis by prompting the users and clubs with questions that encourage more critical analysis of each section. Iāve been building all the infrastructure for running the club so thatās the next more interesting step I havenāt explored yet.
I'm working on lots of projects. My favorite is what I call "context bonsai" where I'm giving LLM harnesses the ability to surgically edit the context. It's available as a tool. You can say "remove that failed debugging session and write a summary of what we learned." Or you can take a more hands-on approach and say "remove messages msg_ID1 through msg_ID2". The removal leaves a summary and keywords, and the original messages can be pulled back into context if the LLM thinks they're useful.
I would really like people to try it out and report bugs, failures, and successes.
https://github.com/Vibecodelicious/opencode/blob/surgical_co...
I'm currently trying to get the LLM to be more proactive about removing content that is no longer useful in order to stay ahead of autocompaction and also just to keep the context window small and focused in general.
I find it fascinating to give the LLMs huge stacks of reflective context. It's incredible how good they are at feeling huge amounts of csv like data. I imagine they would be good at trimming their context down.
I did some experiments by exposing the raw latent states, using hooks, of a small 1B Gemma model to a large model as it processed data. I'm curious if it is possible for the large model to nudge the smaller model latents to get the outputs it wants. I desperately want to get thinking out of tokens and into latent space. Something I've been chasing for a bit.
Yes - I think there is untapped potential into figuring out how to understand and use the latent space. I'm still at the language layer. I occasionally stumble across something that seems to tap into something deeper and I'm getting better at finding those. But direct observability and actuation of those lower layers is an area that I think is going to be very fruitful of we can figure it out
I'm sure you're aware but it's worth pointing out that you will lose all your cache hit discounts with some providers. The next turn will incur the cost of the whole trajectory billed at fresh input token rates.
As an aside, 95 pages into the system card for Claude Opus 4.6, Anthropic acknowledges that they have disabled prompt prefill.
Yes, I have already made deliberate cache decisions and plan to do more once it's working the way I imagine. I think the trimmed down context will have way bigger effect than the cache stuff, though.
As far as I understand, it's caches are not a "next-turn" thing, but a ttl thing.
I made the "retrieve" tool, which is what pulls back previously removed content, append to the conversation rather than putting it back where it previously was. But it's a but premature to really know if that's a real optimization.
I've been on and off attempting to reverse engineer old Sierra games in Godot. I've brought in AI to build tooling to speed up asset extraction from the old game files which has been a huge help. I just got building placement working last night which was a huge win.
This is part of a small hobby where I try to recreate aspects of old games myself to see how I would implement them. I eventually hope to have the skills to create the kind of game I miss playing when I was a kid 30 years ago.
any place to follow your progress on this? sounds very interesting
I have about 10 unfinished blog write ups that I should publish. Let me get that sorted and I can link it in
I've been building several things lately in my spare time:
- After Actions (https://www.afteractions.net/) - The company I work for pays for retrospective software, and I figured I could make my own. So I did! Good for agile retrospective ceremonies
- Data Atlas (https://www.data-atlas.net/) - Right now, it's a basic JSON Schema form builder with a UI on top, but I intend to expand it and improve it to be more than that this year.
I've been working on a BuddhaBoard-like app and a few other projects, but nothing I'm prepared to share right now. Maybe next month :D
Bitwit: Learn CS, logic, and math theory (_not_ DSA) with spaced repetition: https://bit-wit.com/
I was hit by a big wave of depression last year. That crisis gave me a couple of periods of hyperfocus, and I thought I might as well use them to try to improve my mind and my ability to reason.
I haven't had good results learning certain subjects, like CS/math, with Anki or other flash card systems. The only thing that ever seemed to work for me was doing a lot of problems with pencil and paper. But without problems exercising those tools or techniques, they tended to just evaporate from my mind.
So my idea was to combine spaced repetition and problem presentation, and create a system for generating problems and validating their solutions randomly and parametrically. So successive presentations of the same card would present a different problem... and the overall effect would hopefully be that you learn the invariants that each card is trying to present, instead of memorizing some combination of variables and values. Sort of MathAcademy but for CS.
I _think_ it's feature-complete at this point, though I'm still working on validating and publishing cards (and there are a couple of things I wanna do to improve security). I'm pretty early in the dogfooding process, and I'm still the only person using it, and there are definitely bugs. But if anyone would like to try it out, I'd be delighted to hear your feedback (email in profile, also on site). Just maybe go a little easy on me right now, lol :/
The Boolean Logic and Lambda Calculus subjects are free forever, and the first topic of each other subject is also free, so if you're intrigued you can use it for quite some time (literally months) before even needing to provide an email address. No need to pay for anything.

I didn't have a ton of time to play with this but on first try this is awesome. Looking forward to spending more time playing with it
I've been building VVM: a language for agentic programs where the LLM is the runtime.
Most stacks today keep orchestration in Python/TS and treat the model like an API. VVM inverts this. You write a `.vvm` program, paste it into an agentic session with the spec, and the model simulates the VM and executes your program. This is configured via a plugin, no SDK or build step required.
```
agent researcher(model="sonnet", skills=["web-search"])
agent writer(model="opus")
papers = @researcher `Find recent papers on {topic}.`(topic)
# semantic predicate ā semantic if condition
if ?`sufficient coverage`(papers):
else: export report```
It's open source and current runs as a Claude code plugin and the repo includes 37 examples from basic agent calls to advanced patterns that showcase building resilient workflows.
Still pre-alpha -- the spec is fairly complete, but tooling is early. Mainly looking for feedback from people building agentic systems who've felt the impedance mismatch between imperative code and what agents actually need.

Working on a little "passion project" that has ended up consuming a lot of weekends now, but it's been a lot of fun.
I've been building https://photoweather.app because I never end up having time to look at weather forecasts, which means I also don't go out with my camera enough since outdoor photography is quite a weather dependent activity.. so I'm trying to turn this around by having the app tell me when and where I could be photographing instead.
It's a bit of a challenge for sure, weather forecasts are not always the most reliable, not to mention learning enough about weather to forecast photographic opportunities.. but it's also been really enjoyable to finally build something real and something that I myself actually use all the time.
A project builder.
I often have ideas, then spin cycles on starting the project, getting auth in place, making a marketing page, doing SEO, building and configuring pipelines for mobile app release, etc, etc.
My project builder just takes a name, a few configuration options (do you need payments? Analytics?) and spits out a templated build with Terraform that I can 1 (okay maybe 3) click deploy to GCP + App Stores.
The nice thing (I got help with Claude Code) is that now all my projects are in one place, I have a dashboard where I click in to and edit the code (with hot reloading - it deploys code-server and the applications in a small Kubernetes cluster, each project has its own pod) and when I am done editing I just click Deploy and it updates the "production" service in Cloud Run.
Not really interested in selling it as a service or anything (it's a bit too opinionated for that), but it's a very fun project to work on. I need to make Git + Versioning of the code work right now you only have a single copy of the code which isn't great!
back working on my lighting desk, after a couple of years of hating it because the communications bus between the many different modules was flakey and so the whole thing wasn't fun to use. I bit the bullet last year and re-implemented everything with CAN-bus communications and it's actually fun to use now.
Current work has been improving boot time. Was nearly two minutes because of one board, and that's a long time for the lights to be out if you have to reboot during a show. I'd wanted to use buildroot to get a custom kernel that should boot much more quickly, but the buildroot learning curve was steep for me, particularly as I've no expectation of ever needing the knowledge again.
Independently but concurrently I decided I really ought to understand what all this AI stuff was about, for fear of getting left behind. That coincided with the release of opus 4.5, and holy heck has it made a difference! With a little guidance from me Claude got the buildroot environment working and the boot time down to less than 10 seconds. I've been _really_ impressed. I've had Claude write a few boring utilities that I could easily have done but Claude managed much faster and with less boredom on my part. Fortunately for my AI revolution I think I'm a better Business Analyst/writer than I am a coder, so it fits with my temperament.
Sponder - Filter and transform RSS feeds or Podcasts (https://sponder.app)
Different RSS clients provide different filtering options, and lots of them limit you to a few keywords and/or put them behind a $7-12/mo subscription. I'm building Sponder so you can curate what you see, and it just presents another RSS feed, so you can keep using your favorite client but fill in the feature gaps.
Right now it can merge and filter by string or regex, and next I'm building (because it's what I want) history replay and smarter podcast rerun detection. it's new and I'm very open to feedback and feature requests.
I also am building Phaestus, a 0 to product system, that builds entire products from scratch.
https://www.mikeayles.com/#phaestus-wip
It is capable of creating a PCB (and outputs gerbers, bom, pick and place files), an enclosure (written in SCAD, outputs an STL for printing), and firmware, which it's able to compile using a pio runner on railway and provides a binary, but also has a webserial flasher for ESP32's.
There is a blog here, but i've been focussing on getting things finished, as I built it for a hackathon ending today.
https://phaestus.app/blog
I need to update the blog & writeup, because I have the first product it created, a bluetooth remote control. It wasn't without issues, but I have a working PCB, in an enclosure that was printed from it's design, running firmware it generated.

Micropay - Stripe for the next billion people (https://micropay.dev/)
Hi HN, I built this because I got tired of fighting with integrating payments in Africa.
M-Pesa processes over $300B annually, it's how 50+ million people in Kenya pay for everything from groceries to rent. People don't have bank accounts, but rather pay straight from their cell phone nummber. But integrating it into your app? That's a different story. Most developers spend weeks on what should take hours, it's almost impossible. And existing solutions for Mastercard, Paypal, Apple Pay etc are useless because most don't have bank accounts.
Micropay is essentially what Stripe did for credit cards, but for mobile money.
I'm still building https://techposts.eu - the Hacker News for Europe!
Some stats so far:
- 200 users
- 378 startup jobs
- 500+ posts
- 2800+ funding rounds
- 1700+ startup companies
- 5000+ investors
The next part of the project is Tech Posts Intel: a lead gen tool using statistical methods to predict which companies should have a funding round coming soon. I'm hoping to soft launch it this week.
I'd love to hear anyone's feedback on the website. Advice on how to get inbound links in 2026 would also be greatly appreciated!
Borrow This And Improve It - an app for tracking repairs to a thing (right now it's bicycles only, planning to extend to other things like leaf blowers and electronics) and giving away half broken things or repaired things to others but with the advantage of also giving away the repair history for something. So for example, I found a bicycle in the trash, fixed it up with a few new parts (less than $6) and soon I'll try to give the now repaired bicycle away to a new home, plus a QR code that links to its repair history. The idea being that knowing how something was fixed once will make it more likely that it would be fixed again.

Lately Iāve been interested in how budgeting apps model cash flow over time. A lot of tools are either expense trackers or monthly budgets that assume clean month boundaries, which breaks down quickly if youāre paid biweekly or irregularly.
Envelope budgeting (the method) works by allocating money up front so future obligations are actually covered before spending happens. But the hard part is handling income timing and paycheck variability without overfunding the future.
Anyways, Iām currently adding a cash flow detection algorithm to Envelope (the budgeting app) https://envelopebudgeting.com that only allocates paychecks to obligations before the next paycheck unless future funding is strictly required. That approach has avoided a lot of timing edge cases I kept running into.

Building ExoAgent: a security layer for AI agents that enforces data flow policy, not just access control.
The problem: agents like OpenClaw can read your email and post to Slack. Nothing stops Email A's content from leaking to the wrong recipient, or PII from ending up in a Slack message. Current "security" is prompts saying "please don't leak data."
The fix: fine-grained data access (object-capabilities) + deterministic policy (information flow control). If an agent reads sensitive data, it structurally can't send it to an unauthorized sink. Policy as code, not suggestions.
Got a working IFC proof-of-concept last week. Now building a secure personal agent to dogfood it.
What integrations would you want if privacy/security wasn't a blocker? What's the agent use case you wish you could trust?

In my evenings and weekends I've been working on a photo sharing app for families who want to keep their photos off of social media but still share with family.
I'm expecting my first child soon so I am building it for me and my family first but if it solves a problem for me, maybe others will like it!
The basic idea is that you are uploading a curated set of photos you want to share, not your whole camera roll.
You can create one or several family groups that you can share individual photos or albums to. Members of those family groups can view, comment on, like, etc those photos.
You can also generate sharable links for people who don't have an account with a configurable expiry time.
It currently more or less works on the web but I am also working on iOS and Android apps since that is how my extended family would want to interact with it.
I'm not quite ready to launch it to the public but if anybody is interested in trying it out or offering feedback I can privately share it :)
Nice. I store my photos on Dropbox and now duplicated locally on a home NAS. They don't have a photograph based product like Google memories, which I really like. I've been de googling and looking to reproduce it.
I've been noodling with running a preprocessing step to "tag" pictures and videos with a set of tags with richer spatial and temporal features with off the shelf models and then just let a local AI model pick one based one what might match today's theme.
Are you using any models to make your curation step easier/better UX wise? e.g." Compose all Christmas pictures with Grandma and the kids on vacation" and it would give you a collection to curate from my library
One of my priorities is end user privacy so I'm trying to minimize how much access my service would have to the users library of photos.
Rather than me scan all of the photos I'd prefer the user manually select them. Plus, you get the bonus feature of also getting to review your own photos again :) I find a lot of the time I never go back and look at photos I take. I'm trying to evoke feelings of printing photos and putting them in an album. Digital is no substitute for physical, but if I can get close I'll take it haha
I am considering some ease of use features like library scanning / tagging maybe on an opt-in basis perhaps.

amazing!
Appreciate it!
Can't really share any useful link at the moment, but Iāve been working on a solution based on the C1001 mmWave sensor. It collects telemetry throughout the night, including respiratory rate, heart rate (BPM), number of turnovers, apnea detection, and overall sleep quality - you just need to hang it around the bed. The data is sent to a server, which generates a nightly report and passes it to an LLM for analysis.
I've decided to do it simply because of my grandmother: she dislikes bracelets and smartwatches because theyāre uncomfortable and she often forgets to wear them. A contactless device could be much more practical for her and for many people like her.
This is really, really cool. I would replicate and would be happy to share data on this if you want to let me help!

I'm one of the maintainers of PGlite - PostgreSQL in WASM.
We have lots of updates in the pipeline, just listing some of them:
- making it easier to upgrade PostgreSQL's version
- PostGIS - this is one of our most requested extensions and although we have it running server side (ie node, bun, deno) Chrome is holding us back from releasing it
- multi-connection multiplexing over a single instance
Native library is also on our radar, just needs more time...
This sounds fantastic for running local "unit"/integration tests.
We do this, can confirm its very nice
Iāve been experimenting with a live win probability predictor for the 10-player arcade game Killer Queen. The goal is to predict the winner in a causal, event-by-event fashion.
Right now Iām struggling to beat a baseline LightGBM model trained on hand-engineered expert features. My attempts at using a win probability head on top of nanoGPT, treating events as tokens, have been significantly worse. I am seeing about 65% accuracy compared to the LightGBMās 70%. That 5% gap is huge given how stochastic the early game is, and the Transformer is easily 4 OOM more expensive to train.
To bridge the gap, Iām moving to a hybrid approach. Iām feeding those expert features back in as additional tokens or auxiliary loss heads, and I am using the LightGBM model as a teacher for knowledge distillation to provide smoother gradients.
The main priority here is personalized post-game feedback. By tracking sharp swings in win probability, or $\Delta WP$, you can automatically generate high or low-light reels right after a match. It helps players see the exact moment a play was either effective or catastrophic.
There is also a clear application for automated content creation. You can use $\Delta WP$ as a heuristic to identify the actual turning points of a match for YouTube summaries without needing to manually scrub through hours of Twitch footage.
Big fan of this game. The arcade version is a blast if you can find it in your particular city.
Are you playing competitively (league play, tournaments)? Or just passionate about the game?
I used to play very competitively, but I've been more chill recently. I just think it's a nice problem/dataset to work with, because of the depth of my understanding of the game.

Currently building https://auth-email.com
Many mainstream email providers have switched to require OAuth for login, but there are tons of clients and apps that donāt (or canāt) support OAuth.

Working on Memory Store: persistent, shared memory for all your AI agents.
https://memory.store
The problem: if you use multiple AI tools (Claude, ChatGPT, Cursor, etc.), none of them know what the others know. You end up maintaining .md files, pasting context between chats, and re-explaining your project every time you start a new conversation. Power users spend more time briefing their agents than doing actual work.
Memory Store is an MCP server that ingests context from your workplace tools (Slack, email, calendar) and makes it available to any MCP-compatible agent. Make a decision in one tool, the others know. Project status changes, every agent is up to date.
We ran 35 in-depth user interviews and surveyed 90 people before writing a line of product code ā 95% had already built workarounds for this problem (custom GPTs, claude.md templates, copy-paste workflows). The pain is real and people are already investing effort to solve it badly.
Early users are telling us things like one founder who tracked investor conversations through Memory Store and estimated talking to 4-5x more people because his agents could draft contextual replies without manual briefing. It helped close his round.
Live in beta now. Would love feedback from anyone who's felt this pain! :)

A django-based "offline" social media platform (i.e. forum) designed for access only from a single (isolated) WiFi network via captive portal techniques. The goal is a "digital bulletin board" that is geographically isolated and community-moderated (think Reddit's karma system but enough down-votes will delete your post).
Not anywhere near production-ready yet but if this is up your street and you want to contribute then I'd be grateful! I have the back-end stuff well under my belt but I'm allergic to javascript and my CSS skills are pretty limited also.
Also in the works down the line: a simple document management system (another Django app, probably) that allows basic but ISO-compliant document control (centralised access controls, automatic document-numbering, review/approval and draft/issue processes, configurable document indices, etc.) aimed at SME or contractor use. Everything else I've tried in this category of software is either abandoned (or otherwise stuck with a tech-stack from nineties), active but a PITA to ensure ISO-compliance, or hugely over-complicated (i.e. ideal for a big corpo but too much admin overhead for an SME) so I'm brewing my own that aims to meet the minimum feature-set needed for easy ISO-compliance.
I'm working on a (somewhat) realistic surfing game. Tired of arcade-style games, I decided to try my hand at something closer to the real sport, focusing on realistic breaking waves, speed generation and carving, rather than impossible air combos.
After one year of development, it's going better than I expected, so I'm considering building a demo to gather feedback and see if there's enough traction for working towards a Steam release.
Even if that's not the case though, it's been a blast learning about game dev in Unity/C#, as well as 3D modeling and animation in Blender!
Hi I'm a big surfer (or have been most of my life but doing less now at 40!) also building a mobile game in Unity/C# right now although it's not surf related like yours it's actually based on Chinese Wuxia cinema from 5 years spent in China. I considered building a surf one and was looking at potentially trying to 'gamify' a slightly different element of the 'surfing' experience which was to focus on predicting/catching and then staying on a wave at a busy break...so top down early GTA style graphics initially waves would come almost breaking in random spots in relation to previoius waves/sets, but never identical, and you'd have to kind of 'guess' ahead of other AI controlled surfers where to place yourself then paddle for position then try to dodge others on the way in....I thought it could be kind of fun in an arcadey way and not require so much of the physics you're describing, which is no doubt really hard to code...I'd love to see your game though!
I guess the trickiest part is fluid dynamics. Are you using a physics/fluid sim or handrolling your own?
I believe realistic fluid dynamics in the scale of a full breaking wave is unheard of for real time graphics, there's just no way to do it in 30-60FPS (I could be wrong tho!)
What I do instead is to transform a procedural plane mesh into wave-like geometry. For added realism, I base this transformation on bathymetry data (ocean floor height), so you can get left/right breaking waves, different breaking sessions, etc, just by defining different heightmaps.
How's it compare to kelly slater pro surfing
KSPS was my favourite surfing game growing up. What I dislike about it though is the infinite/perfect waves (always a truck-sized barrel opened, you can do tricks anywhere, almost no differentiation between waves) and the focus on impossible airs and tricks.
In my game the waves start, break and end, with different sessions and hollowness, so there's more wave reading involved. Also the focus is on being able to stay on the wave and generate speed, doing cutbacks, snaps, off the lips, etc.
https://azayrahmad.github.io/win98-web/ Another Web-OS remake of Windows 98 made with vanilla JavaScript. There are already a lot of Windows web remakes, especially in this age of AI.

Currently it has:
- Accurate recreation of Windows shell with start menu, taskbar, windowing system.
- Full desktop themes customization (color, cursor, sound, wallpaper, screensaver). All Win 98 default Plus! themes are included.
- Persistent local file system & mounting local folder as removable disk with ZenFS.
- Support playing Flash games and run DOS games (save game persisted). Yes, you can play Doom and copy your savegames to continue.
- Some accurate remakes of Windows 98 apps, some made by me (Solitaire games, Minesweeper, Notepad) some are existing ports (Pinball, JSPaint, Webamp, etc).
- Some other fun stuff
If you're interested in Windows 98, this is for you. You're also welcome to contribute or fork it to create your own version: https://github.com/azayrahmad/win98-web
>Internet Explorer opens websites as they were in 1998
Impeccable.
I'm working on a language learning framework based on the ideas of comprehensible input and spaced repetition learning.
The idea is you take a book you want to read, and it gets translated but also rewritten to match your current learning level. And as you read/listen it introduces new words to learn, reinforced by spaced repetition.
We're taking a trip to France this summer and I'm hoping to have something usable for at least a couple months before we go.
Currently working on the mechanics of extracting content from ebooks.
A pricing API for the Counter-Strike 2 market that provides real-time & historical data.
The market is distributed across a bunch of 3rd-party marketplaces, and there's no 'simple' API that provides genuinely high-quality data. It's been a super fun project, and I've been able to learn about collecting & managing a high (to me) scale of data, building an API from the ground-up, and creating my first 'commercial' website.
Website is @ https://cs2.sh/
The API is built w/ Go & Clickhouse, which I've been super impressed with so far.
Web design is partially inspired by turbopuffer's site.
Iāve been iterating on Toolbit (https://toolbit.app), a local developer utility app I initially shared a while back.
It started as a small attempt to stop bouncing between dozens of web tools for things like JSON/JWT, base64, regex testing, cron expressions, and similar āglue workā tasks. Over time itās grown into something I keep open all day.
Since the last time I mentioned it, Iāve added quite a bit: ā¢ ~40+ tools now (regex tester, PDF merge, image conversion, cron builder, etc.) ā¢ workspaces for grouping tools around a task ā¢ tool chaining instead of constant copy/paste ā¢ snippets, history, and recent items ā¢ automatic detection (paste data, it routes you to the right tool)
Itās an Electron app and runs fully local. No accounts, no tracking, no sending data out. The goal isnāt novelty, just reducing friction in everyday dev work.
Iām still smoothing rough edges and figuring out where this is most genuinely useful. Curious how others here think about scope creep vs. ādaily driverā utility tools, and whatās worked or failed for you in that space.
Still working on:
https://www.votivus.org
A hobby project I started putting together late last year; a little spot on the internet for prayer and reflection.
https://dugnad.stavanger-digital.no/
A pro bono tech consultancy for local non profits. The idea is to help them use tech to better deliver on their mission.
Just today I finished off building a little PWA to help a couple of non-profits offload the admin of volunteer scheduling (mostly done through whatsapp, messenger, etc).
I'd recommend others try the same pro bono consulting in their local area, it's quite rewarding!
This looks awesome.
Thanks!
I've been having a lot of fun modding 7 Days to Die (zombie game) using Claude Code. I have a strong development background but I've never worked on games before. Without AI it would be completely inaccessible to me without months of catching up.
7DTD is built on Unity Engine and modding is mostly done with XML/XPath and C#. I have yet to install Unity. I have a CLI setup, including a script to disassemble relevant 7DTD assembly DLLs into C# and copy other info from XML files into a directory in my repo.
This "refs" directory has about 800k lines of C# code and 300k lines of XML. Claude can figure out how to add a feature or fix a bug with a few minutes of searching the refs. At first it took 5-10 attempts to get results that actually worked, but now it's often 1-3.
Here are the mods I've released since early Jan:
- SteelUI: fixes for it to work with the latest game version[1]
- Smarter-Tools: a mod I authored from scratch to add a few tweaks to how tools work[2]
- More-Gore-Continued: has serious performance issues I'm working on - making progress[3] (adult only - requires sign-in)
If there's any interest I'm considering writing up all the details in an article and making the mod repos public.

A hobbyist analog computer I will open-source.
I have been through a number of iterations of adders, integratorsā¦ It's starting to coalesce now into a finished PCB. (Iterating is slow though at the PCB stage since we're round-tripping via Asian PCB fabs.)
As often happens, I want to learn about something (analog computing in this case) and I find that a deep dive where a kit comes out at the end is an enjoyable way to explore (I also get more experience with KiCad and, for this project, SMT).
The seed of this were a few articles on building a "lunar lander" circuit in early '70's electronic hobbyist magazines I found online. Pre-home-computer, how does one create a lunar landing simulation? Why with op-amps and panel meters of course.
And so that is where I began. But I'm way past that now though by making instead a general purpose analog computer.
Building PushMe: A service that sends you notifications for anything you care about.
I was wasting way to much time scrolling news. It consist of a crawling engine, de-duplication, llm creating a custom keyword filter and each event is checked against the original prompt for verification using a llm before sending it out.
Keywords suck, 381 of 388 potential matches end up like this:
"The event is about an OpenClaw Plugin Hub supply chain attack, not a data breach affecting hundreds of millions of users. The watch request specifies a massive data breach; the event does not clearly indicate that."

Working on Whisperit v3: a document automation platform for lawyers, voice-first.
The idea: lawyers spend 60%+ of their time writing documents. We give them an AI assistant that actually understands legal context ā case files, templates, emails, the full picture.
What we've been shipping lately on the v3 branch:
ā¢ Workflow engine ā visual editor + execution pipeline for legal document workflows (think: intake ā draft ā review ā send, all orchestrated)
ā¢ Case-context AI assistant ā docked right into your case view, with file attachments, skill system, and next-action suggestions. It knows your case, not just your prompt. Think Pipedrive CRM for lawyer!
ā¢ Skills system ā modular prompts lawyers can pick and inject (summarize deposition, draft motion, extract key dates, Claude Skills, etc.)
ā¢ Cloud drive sync ā bi-directional sync with Google Drive and OneDrive. Lawyers keep their existing file setup, we plug in and keep everything in sync
ā¢ Outlook, Gmail, IMAP email integration ā connect your inbox, pull relevant emails directly into cases
ā¢ Template multi-output generation ā one case, multiple documents generated in one flow
ā¢ BYO AI provider ā user/workspace/admin level settings for AI models. Some firms want Azure, some want Anthropic, we let them choose
ā¢ Canvas boards with AI context for visual case planning Stack: Next.js 16, FastAPI + LangGraph backend, Supabase.
We're a small team in Switzerland and across the globe, shipping daily. Target is Q1 for the v3 launch. If you work in legal or know lawyers drowning in document work: would love feedback or test our beta :)
https://whisperit.ai
What did you use to record the video on the home page, if you don't mind me asking? I need to do something similar. One tip I've seen is to record at a higher resolution than you need, then scale down. The demo is good, but looks a little grainy at points, FYI.
Of course! I have looked into many tools to be able to do that properly. This one was done with Screen Studio, which is one, and there is another one that is nice and open source: Cap - but a bit less features.
ComputerPoker.ai
We trained PyTorch models on solved poker scenarios for post-flop, turn, and river situations. The planned "killer feature" is to give users feedback on their poker play in the flow of a simulated poker tournament or simulated cash game scenario. The goal is to play against "GTO Bots" (Game Theory Optimal Bots) to learn how to play closer to GTO.^1
Poker has been a passion of mine for a few years now, I find the game incredibly intellectually stimulating as well as a tremendous catalyst for personal growth, and this project has been a great way to channel that energy.
The web app uses Django/Channels/WebSockets. We've built an internal discounted CFR solver as well, hopefully building up to multiway scenarios in the future. The webapp is still in Beta/gated, and you're interested in learning more please email contact at surlesol dot com.
We are thinking of pricing $8/month or $74.99/year, with the rationale that this will be far less expensive than learning by experience at even micro stakes for online poker, with better feedback for learning, and at least we make it explicit that you're competing against bots ;-)
1. I am aware that GTO play is not always optimal, especially in live poker where live tells are available, and often exploitative strategies fare better than pure GTO. The target audience for ComputerPoker.ai is not hardcore poker pros, there's plenty of existing software for that, but rather those individuals looking to get acquainted with what GTO play "feels like." Then, with this knowledge in hand, knowing what the GTO play would be given various assumptions about our range and a reasonable opponent's range, we can deviate from the GTO play as deemed necessary.
I have been working on a web app called Beval - Simple evaluations for your AI product.
In my day to day as a Product Manager working in a team that ships AI products, I often found myself wanting to do 'quick and dirty' LLM based evaluation on conversation transcripts and traces. I found myself blocked by 'Gemini in Google Sheets', it was too slow and cumbersome, and it didn't handle eval changes well. And because I was exploring, it wasn't helpful to try and set up something more robust with the team.
To fix the problem I eventually learned to call the OpenAI API in python, but I really felt that I wanted a 'product' to help me and potentially help others.
So this weekend I built https://beval.space
https://wethinkt.com
The second bubble there is a tool for 3D visualization and analytics of Claude Code sessions. The sample conversation is the one that made the tool itself!
That was a fun toy I learned a lot from. Iām not expanding that but am working intensely on the first bubble:
thinkt a CLI/TUI/Webapp for exploring your LLM conversations. Makes it easy to see all your local projects, view them, and export them. It has an embedded OpenAPI server and MCP server.
So you can open Kimi and say āuse thinkt mcp to look at my last Claude session in this project, look at the thinking at the end and report on the issues we were facingā.
I added Claude Teams support by launching a Team and having that team look at its own traces and the changing ~/.Claude folder. Similar for Gemini CLI and Copilot (which still need work).
Doing it in the open. Only 2 weeks old - usable, but early. Iām only posting as itās what Iām working on. Still working on polish and deeper review (it is vibe-crafted). Thereās ergonomic issues with ports and DuckDB. Coming up next is VSCode extension and an exporter/collecter for remote agents.
I am in the early stages on building a passion project called Metric Me - A dashboard for your body.
https://metricme.app/
Over two decades ago I was diagnosed with high blood pressure (for which am I have been on meds for about 15 years). I also have low platelets (red blood cells, basically means that I bruise easily and that small cuts don't heal fast). At any rate, I do blood tests on a regular basis to keep things in check. I have been keeping track of test results, weight and blood pressure result for nearly 20 years, but the data lives in a text file on my desktop. I wanted to build something more substantial for this for quite some time now, so, this is it.
I always wanted a minimalistic CSS framework for my projects, so I started to create my own: THINK
THINK is a modern CSS-first UI framework built on semantic HTML, custom elements, and data attributes. Uses :has(), container queries, and density scaling. No classes, no build step.
Itās work in progress but Iām pretty happy with the outcome so far, especially the data table component and automated Insights. I know itās not AI driven - but it works pretty okay for quick insights on the loaded data.
https://think.iotdata.systems/
Looks nice! Semantic HTML is such a relief if you've ever encountered a div hell.
This is very cool! Is it open-source? I'd love to see what it's like to use
I just created a repo: https://github.com/marchildmann/IDS-Think It's MIT licensed. Would love feedback, especially on the data table component.
Been using tachyons.css
Would love to take this for a test if it is available for public use

Video Reject is a platform for people to buy/sell physical media. Like Reverb but for physical media.
I love movies and wanted an excuse build something in that world. Its not necessarily groundbreaking, but I think it could build a nice community of folks with the same interests.
We're getting ready to launch, but in the meantime, we have a waitlist up.
- A stair lift for stuff, not people. Retrofits onto any stairs and self-locks without damaging the stairs or blocking the path. Allows you to bring groceries, laundry, senior dogs up and down stairs with the push of a button. Currently can pull 50lbs.
- A bracelet with tiny camera that's pointed at your hand palm and transmits pictures of the stuff you're holding and where you've put it down locally to your phone. Pictures are sent to a quantized CLIP which allows you to search for anything you've lost without needing to attach an airtag to it. Works decently well and is great for 'power losers' like those with ADHD-I. Has a privacy slider and nothing goes to the cloud.
Would love to hear from anyone interested > hi @ hitch-home dot com
Building TimeCap: an app that removes the addictive sections of any social media. That means that you can check your friends' updates on Instagram without getting distracted by reels.
It is fully customizable, works on any social media, and it genuinely brought my screen time to less than 1 hour.
It is free to use for one platform, and is $29.99/yr for unlimited. And if you need the premium version but can't afford it, just send me a message and I'll sort you out.

Building https://typequicker.com
Weāre aiming to build the best typing application; personalized to every users typing habits.
Typing is one of the most important hard skills today and yet most education systems skip it.
Most of our customers are adults who always wanted to type but canāt find the time. We make it faster to learn and improve by focusing around the userās weak points (with our features like SmartPractice and TargetPractice)
I've been working on a browser extension to make Hacker News easier to use. No, not change the UX, but just some nice conveniences. Keyboard navigation, inline replies, dark mode, a nicer topcolors page, and many more features. I am hoping to add some social features, like being able to follow someone. All in a well-tested and extensible codebase that has minimal impact on the site. Open source, GPL...
Orange Juice
https://oj-hn.com
Sounds great! I've been thinking about making something similar now for a while.
If you don't mind me sharing ideas that I would love to have in such an extension:
- Changing the UI of the comment actions to make them easier to use. Using HN mostly on a phone, I keep hitting downvote when I mean to do the opposite. Similar with the collapse action.
- Keep a local list of users that get their comment subtrees stripped out. Some people are argumentative by nature and not in good faith. It's best to ignore them (easier when you don't see their comments).
- Hide new accounts by default (perhaps auto collapsed).
Thanks for the feedback!
So far, desktop is the current target. Not even sure I can run extensions on a phone.
The last two fall under content moderation. I'm a bit less interested in that as it changes the UX and there are infinite things we could do there. Right now, the extension has no preferences switches, and I'd like to keep it that way for as long as possible. When there are a whole bunch of knobs to tweak, it makes everything overwhelming.
Fair enough, and I understand the arguments against adding that.
On the mobile extension side, just in case you were unaware, Firefox on Android has had extensions now for 2+ years.
Good luck with the project!
Developing LogiModel AI (https://www.logimodel.com/) which is an agentic supply chain optimization engine that forecasts demand, optimizes operations, and simulates scenarios to reduce costs while keeping your network reliable and customers satisfied. It integrates seamlessly with your ERP and document repositories to learn your business context, then acts as an intelligent decision engine, freeing you to focus on strategy while it handles execution.
Always interested in possibilities of LLMs interfacing with MIP solvers.
Also, this was a quick fun project for a multi-agent flow https://flickfeast.party/
I'm building a tiny experimental message board / ...game? called Isles (https://isles.app/about). The short pitch is that when you sign up you're randomly assigned to a small island, and you can only interact with people on that island. Randomly, islands link up and you can migrate/explore the other island. I wanted to play with ideas of cultural exchange on a really small scale. I don't have any regular users yet, but if any of that is interesting to you, you should sign up if only to say hi.
Tech I'm using: Sprites, Cloudflare Workers, SQLite, Litestream, React SSR
Iāve been working on https://og.plus, a service that creates unique Open Graph images per page on a website.
It does this by taking a screenshot of the page, but before it does that, you can modify whatās displayed in the screenshot with CSS, tailwind classes, meta tags, or HTML templates.
If you connect your website to it, the only thing you need to deploy to your web app are a few meta tags. The OG+ servers do the heavy lifting of processing the meta tags to setup the page, take a screenshot of it, and serve it up to the consumer.
The other cool thing it does is generate a different Open Graph images per social network so they all get an image for the exact size they works best in their previews. The CSS or HTML templates are aware of this too so you can display different content to specific social networks.
I am working on an app that uses old-school predictive AI (i.e. pytorch and scikit-learn) to predict professional sports outcomes in a way that is useful for DFS fans. Here is the landing page.
https://www.higherscoresdfs.com/dfs/spa/welcome/
Here is the pitch.
We seek to empower DFS fans through education about predicting professional sports athlete outcomes. We do that through strategy advice, hot player tips, optimized lineups, and pickāem style game-friendly player props. We're not trying to take away your control or do your thinking for you. We are just here to support you in making better decisions. Let the app do the number crunching so you can get back to competitive play that gets results and is also fun.
I've just started a new personal project, a C++20 library for running composable visitors over data documents and data models with JSON/CBOR semantics, DOM-less.
Basically, if you define a data model with bindings, you can inject data into it or extract data from it by running SAX-style visitors. You can use serializers/deserializers for standard formats like JSON/BSON/CBOR/CSV, or you can define custom formats for formating structured data however you want to. You can also run a serializer visitor on a deserializer to convert between formats. You can compose filter visitors to extract a subtree or filter out keys. And it's designed to fit on microcontrollers with very limited dynamic memory allocations, because it either streams data on-the-fly or works directly with the underlying data format in a big preallocated buffer.
I worked with libraries that offered a subset of these features before in my professional career (even built one myself), but recently I've had an epiphany (a document can also be used as a data model) that makes me think I can create something elegant and unique.

Inspired by a TED talk I saw [0] where the researcher from Microsoft displayed a program with AI assisting with thinking while someone was reading and annotating a document. They claimed it was a way to sharpen critical thinking instead of killing it. They didn't release the product, but I figured it was cool and useful, so I've spent the weekend creating it. It's been a great way for me to practice using agents, and I've learned a lot from this process.

Recently, I got banned from Reddit for sharing my local news summarization website (www.cafelutza.ro) - for the Romanian market. So I figured you know what, I've been trying to bring this product to Reddit in the hopes of having better discourse around the news, but instead I realized, I was looking for smart discourse around a subject, which I haven't been able to find on Reddit or elsewhere, so I created Exppit (https://www.exppit.com) that basically gets experts to debate your topic of choice.
I'll admit it's terrifying to share this here because I don't know how to keep costs under control. For now only myself and my friends have used it.
Also trying to make a podcast out of it, which I enjoy listening to while I do some road trips: https://open.spotify.com/show/1fFwWMWJBJYIZmyz9cnrKB
> Recently, I got banned from Reddit for sharing my local news summarization website (www.cafelutza.ro)
how exactly this happened? What did you do?
> that basically gets experts to debate your topic of choice.
The word basically is doing a fucking lot of heavy lifting in that sentence given that it's essentially asking spicy autocomplete to pretend it's multiple (possibly dead) people from $field to discuss the topic amongst themselves.
I mean... I'm pretty sure anyone that gives the front page a read can tell that it's spicy autocomplete. The alternative of having Aristotle chiming in to one's shower thought would be harder to explain.
The description I replied to suggests it's a place for actual experts to discuss a topic. It makes no mention of it all being fake.
https://radius.to/ - a Meetup.com alternative of sorts - with fairer organiser pricing for smaller groups. I posted a Show HN [1] here a while back, got tons of great feedback, and have been slowly improving it since, with little marketing. Planning a re-launch here soon.

Hello fellow Scot!
I missed this when it was launched and it's very interesting to see your rationale. If you ever want a chat some time get in touch, I'm working on https://opentechcalendar.co.uk/
My ulterior motive is to ask you to add open data feeds for basic group and event listing information to your site - a free and open API and standard formats like ICAL (Just listings information about the next event, not private info like members names). I would never encourage event organisers to use a platform that didn't do this, as then their data is essentially being held hostage and it's hard for them to spread their information around to other places.
Hey! Wow, I knew about OpenTechCalendar but somehow hadn't realised (or likely forgot) how close to home it was! I'll definitely reach out for a chat at some point.
And thanks for the tips - I completely agree on the point about data being held hostage, and on the openness of data - it's one of the more frequent complaints about Meetup. I've recently added an API for event creation, so it won't be hard to add another endpoint for listings (at the moment, we just have an embeddable widget [1] showing your next 3 events).
ICAL is a brilliant suggestion - I've had a few requests for that already, and it's especially interesting in the context of opentechcalendar. I'm very interested in ActivityPub and all things fediverse as well - figuring out how to integrate these ideas into the platform is one of the next items on my TODO list.

Awesome! Love the location based discovery. Unfortunately sign up ended up with 500 error!
I guess the weekend was a bad time to upgrade to Rails 8.1 :) - should be fixed now, was just an issue with Redis. Thanks for letting me know!
Couple of scratch-my-itch apps.
1. Plimsoll Line for dealing with anxieties from mountains of Reminder items, by surfacing the stress factors and taking small actions such as quick journalling and a breathing exercise. The new version with Widget should be released within the next week or two. Version 1 is currently in the iOS App Store. (https://apps.apple.com/us/app/calm-to-do-list-tasks-plimsoll... Calm To Do List&Tasks-Plimsoll). Made it to help my wife (and me!) not get so overwhelmed with things she has yet to do but hasn't started. Also to make it easy to write down things weighing heavy on her mind to alleviate the vicious cycle of emotional decay.
2. Yet-unnamed and -unreleased weather app for planning outdoor activities at times of the day when the weather will be most favorable (or least bad). Made it so that I can plan when to go out to the back yard to bring in more fire wood for the stove in my house. The weather has been tough this winter in the Northeastern US so it finally made me work on the app.
https://github.com/shatsky/lightning-image-viewer
Tiny desktop (pre)viewer which displays image in transparent overlay without any UI, allowing to look into specific image detail with single hand move (zoom with scroll and pan with drag simultaneously like in map apps, with nothing but display borders limiting visible image surface) and toggle between file manager and image view almost instantly (close with left click anywhere/keyboard Enter).
Also finished initial rewrite in Rust just hours ago:) (originally did it in C and intentionally tried to make it initially close to preceding C codebase before going further, so many things are still managed manually)
Iāve been building out https://hnarcade.com for the past weeks. Got a lot of good feedback from the ShowHN thread and others reaching out individually.
Since the ShowHN thread, I received more than 40 individual game submissions!
To give more exposure to some of the games launched during the week I also launched a newsletter. Feel free to check it out if you want to learn more about games shown over the week :)

Also looking into AI based security tools for monitoring security of DoneThat. Thinking of using zeropath would love to hear if people tried them / have other suggestions
Cool!
This feels like it will very easily segway into corporate "spyware" if you ever start doing enterprise plans.
What's your take on that?
I built mine with all kinds of privacy features built in: from never storing raw data to always allowing to review before sharing anything to always offering to pause, excluding apps, deleting data, opt-in for social features, ā¦
So spyware in the sense of getting information without the employee knowing would be impossible and not something Iād ever want to do.
It does enable transparency on a very abstracted level: your team could see a six bullet point summary of your day if you opt in. I believe this kind of transparency can actually help more teams go remote, cut down on sync meetings, etc.
Iām currently experimenting with a feature that shows relative time spent only, not absolute - so e.g. 30% on project X, 20% on admin, etc. That could be the sweet spot on visibility vs privacy.
We're working on learning/pedagogy infrastructure that models the learner by using AI to build a knowledge graph: https://parsnips.notion.site/knowledge ā this is in contrast to the common black-box approach of "use some RAG with a large context window and hope for the best".
In the above article, we list a few applications that we think this could be helpful for: life skills, management/sales training, personal coaching, etc. We'd love to demo the software if this sounds interesting to you!
We're working on the WASTE p2p code base.

Hi!
Iām working on:
- DietPDF ( https://github.com/Zigazou/dietpdf-haskell ) an intensive PDF optimizer which tries to reduce PDF size as best as it can while preserving visual quality. It relies on a lot of tricks to achieve this goal (minification, precision reduction, deletion of superfluous operations, concatenations, filter combination etc.). At the present moment, I'm trying to implement CCITT Fax encoding/decoding.

I'm working on a website that lists veterinary practices owned by private equity or large corporations to help people make more informed decisions about where they take their pets. It started as a small passion project after our dog (who was sideswiped by a car) died at the hands of a vet practice recently acquired by private equity. We were billed over $13k for 2 days of care where his diagnosis and the opportunity to treat it was missed, there was zero continuity of care, no medical leadership and predatory billing practices.
The site has become quite a hit and gets thousands of unique visitors each day. https://www.privateequityvet.org/vet-list
Thatās a great idea and I wonder if youād consider including the UK. My vet got taken over and now they keep spamming me with āoffersā - so I no longer know if my dog really needs a checkup or not.
Thanks! Actually I did add the UK very recently but this is a good reminder to improve the UI to make it more obvious, if you go to https://www.privateequityvet.org/vet-list/map.html you can toggle between US and UK. I have over 2000 practices listed in the UK.
I hadnāt looked- thanks for this. Indeed my vet is listed.
I'm sorry to hear about your dog. It's a sad story. Thank you for building this web site. I hope it helps people and their pets.
I am curious where is this data sourced from! Thank you for putting this together
It's been a painstaking process of combing consolidator websites (eg. PetVet Care Centers, NVA) for practice names, verifying and adding them to a list over the course of over a year. I now get many people writing in to report practices that aren't on the list - admittedly it's not complete list as practices are still being acquired (although independents are now in the minority) and often the old practice branding is kept and the fact it's PE owned is hidden.
Amazing work!
thank you for fighting the enshitification of American Experience.
https://hot.dev
I'm building Hot Dev, a backend workflow platform.
- Hot: a functional, expression-based language w/ types for easy integrations and built-in parallel constructs
- Event Handlers drive execution `on-event: "user:created"`
- Scheduled Events `schedule: "every hour"`
- MCP: Turn any Hot function into an MCP Tool
- API: Real-time access to running tasks; subscribe to workflow Streams with SSE updates
- Observability: System-level dashboard; Call-level tracing; Alerts to email, Slack, PagerDuty, or webhook
- Develop locally, push to production with `hot deploy`
- Coming Soon: Hot Box - run any OCI container as a Hot function

Been working on a Bluetooth based miniature range Locating tag that can be glued or stuck on to any object of choice. (think sometohing like an Airtag, but 1/10th the size and working on Android and way cheaper) The need arose when my old parents kept forgetting where they last left their spectacles. Since I am a electronics and hardware engineer by profession, I am looking for some expertise on app building for his project. Maybe I will turn to an AI assistant for this. I am working on a blog seriaes for his to record my environmental progress. Will be up in a few weeks.
For almost 1 year now, we've been building on a next gen event-driven internal developer platform, an an opinionated selfhosted platform "shoehorn.dev" - deploy with ease within 15 min (docker compose or helmcharts). You could say its a modern backstage. But its way smarter in many ways. Kubernetes native, API first, microservice golang backend architecture. You will be able to configure the platform via our terraform provider too. Deploy our kubernetes-push-agent in your cluster, push kinds and auto creates entities into the API in batches, get podEvents etc. Modular frontend written in svelte, decide what you want to show. We're supporting oidc + orgdata sync for okta, zitadel, entraID. rbac management. Instant search using meillisearch. Auto create orgchart depending on how your teams / deparments are nested. Visualize dependencies "relations" using svelteflow. View entity compliance. Full github integration. widget/integration community etc.
Would love feedback!
https://demo.shoehorn.dev will be deployed soon and full release "beta" will be released in march.

I've been working on my newsletter called Tech Talks Weekly[1] where my readers get one email per week with all the latest Software Engineering conference talks and podcasts[1] published that week.
In January, I've released a paid tier[2] where my subscribers additionally get:
1. Access to my internal database of all the talks and podcasts since 2020 (+48,000 in total) where they can search, filter, sort, and group by title, conference/podcast, view count, date, and duration.
2. The list of the most-watched talks over the last 7, 30, 90 days, 6 months, and 12 months based on number of views.
3. Category-based view of new talks & podcasts by tech stack, language, and domain (Software Architecture, Backend, Frontend, Full Stack, Data, ML, DevOps, Security, Leadership and every major language & ecosystem)

Basically tracking where my friends and I have collectively been by dividing the global map into H3 hexagons. The using photo and workout metadata to get the locations, giving points and doing comparisons between everyone. Itās actually quite fun to see random people around the world sign up and see in the global map where everyone has been. Grounds me a bit haha.
For a moment, I thought it was a game about finding chickens and was confused yet intrigued.

A couple different projects. I've been cataloging and publishing my vintage ad collection at https://adretro.com. It's starting to get a lot of organic traffic after about a year online, which is cool.
I'm also working on a new strength gains-tracking app that is a lot more intuitive, motivating and friend first. I've been using it with some friends for the last 10 weeks and everyone making is consistent gains. It is my first full PWA, vanillaJs, backend is Lucee & MySQL. Works great on iOS and Android, no one has any complaints. The web stack has come a long way I am probably not going to do a native mobile app for a while. I'll probably make it public in a couple weeks.

Currently in Shanghai but will move to Tokyo next week. Once I'm in Tokyo I'll publish a few posts about AI assisted coding and product creation.
Also adding a few things to my ideas page: https://bryanhogan.com/ideas
Other things I'm working on:
- https://dailyselftrack.com/ - Got into working on it again, mainly solving some UX problems currently.
- https://game.tolearnkorean.com/ - Learn Korean words quickly, words go from easy tasks (e.g.) matchings pairs) to more difficult ones (writting it), currently still needs some slight adjustments, and then I'll release an Android version.
- https://app.tolearnjapanese.com/ - Wanted to learn Hiragana quickly, used my existing project as a base to build this. Needs some adjustments as well, feedback is highly welcome.
- https://tolearnkorean.com/ - Since I'm learning Korean, and also working on an app to better learn Korean, I also want to make a guide on learning Korean, improving my own skills by teaching others.

Nice.
BEAM has always been used in high-performance computing applications (Eg. WhatsApp) and Elixir pretty much is the modern Erlang alternative for BEAM, hope this helps.
I was being very serious - this is cool!
Thanks a lot :)
Skulto - offline-first package manager for Claude/Codex agent skills
https://github.com/asteroid-belt/skulto
Started building this after getting nervous about installing random SKILL.md files from GitHub. Scans for prompt injection in markdown/references and suspicious patterns in scripts/.
- 200+ curated skills included
- 33 supported agents
- Symlinks for one install anywhere and automatic updates
- CLI, TUI, or MCP interface: try asking Claude to find and add Awesome repos.
- Semantic search across skill content
Working on: local skill authoring, mise-style directory activation
Go + Bubble Tea. Happy to hear what's missing.
Built this (well, forked and adapted) this morning: https://github.com/leochatain/zsh-claude-code-shell
Couple of utilities for using claude code in my zsh. #? <describe command> => generates the command for you #?? <command> => explains the command for you
Packaged as an oh-my-zsh plugin so it's easy to use.
Learning the autonomous coding, there are so many different skills, tools and ways and only some of them seem to work.
That means I have to: - build something so I can evaluate the results. - track each of these projects separately otherwise they turn into dust after quite some time. Gladly claudesidian seems to be working well with the unstructured stream of inputs. Feel like hooking it up with some task tracker cli and calendar and notifications could make life a bit better too. - plan next projects to keep evaluating other skills and tools
Itās been discussed so many times the amount of new or personalized software that appears and will appear and it seems so true.
Whatever I built I am actively using myself - a text rewriter that cleans some of the AI speak and has MCP and cli (at https://www.refineo.app). Math teaching and solving extension at https://math.photos and a self hosted stock opportunity discovery tool that runs locally. This is just to automate what I did before manually and scale it up a bit.
> Any new ideas
Thereās no product yet to cover the needs of all of us launching the software into the internet void. Any ad platform out there is a hot and very outdated mess and I just canāt. There is going to be a better way with all the capabilities we have and someone is going to really nail it.
Still working on my LPFM radio station, www.kpbj.fm. We launched our regular online stream and have secured a site for our transmitter.
The transmit site is in the Verdugo hills and will need to be off grid. We're going to need about $20k to get the entire transmit system setup (including a solar/battery backup system).
I've also been working on our web infrastructure. The site is built with Haskell and HTMX. The stream is Icecast, and stream scheduling is done using an internal schedule system in the web app and LiquidSoap (so no external tools like airtime, libretime, or azuracast).
HTMX :)
Yeah I'm pretty happy with HTMX. I first cut my teeth on programming in the early 2000s with LAMP stack then Ruby on Rails and Django. It feels pretty great to be able to do a web 2.0 style application but still get most of the functionality of a SPA.

https://github.com/Leleat/git-forge
From the README: "[git-forge is a] simple CLI tool for basic interactions with issues and pull requests across GitHub, GitLab, Gitea, and Forgejo".
Right now, I am looking into better testing. Currently, I do testing by mocking the forge APIs and then running git-forge against them with TypeScript. But not everything is testable that way. The TUI is pretty much untested. So I now want to port at least the tests to Rust (I am probably gonna leave the mock API in TS) and need to look into how to tests TUIs, which is a bit of a challenge since not only is Rust my first "systems programming language", I am also not knowledgable in Terminal/TUIs...
This is the first time I have seen a post like this on Hacker News.
And I just launched Writtte yesterday, a writing platform for drafting articles with built-in grammar checking and AI-based refactoring with custom styles, and for the first time, with a better copy/paste mechanism for other platforms like Medium, and Substack :D

Hosted OpenClaw, one click and you get a full agent with configurable skills, channels and the whole thing, all running in its own sandbox.
I love OpenClaw but setting it up is a pain: VPS, Docker, API keys in plaintext, security patches... So Iāve spent the last couple weeks building a hosted version that handles all of that. Each user gets their own isolated environment on Cloudflare Workers.
Still doing some testing with friends before opening signups but planning to launch properly this week.
Would love feedback on the landing page in the meantime!
You should just launch it no? Iām looking to try one of these and getting to market fast is important because there will be many more very soon.
The use case examples are good, would be nice to include a couple that use browser automation or that feel more magical than reminders.
Is the memory functionality just whatās baked into OpenClaw/Pi or is it customized somehow?
Yeah, itās pretty much ready, Iām just squashing a few last bugs. Launching this week, trying to move fast for exactly that reason.
Good call on the examples, Iāll add some that show off browser automation and more complex workflows.
Memory at launch is whatās baked into OpenClaw, but Iām planning to upgrade it to vectors + a continuously updated doc shortly after (similar to what Claude Web does)
If you want early access Iād be happy to get you set up personally, just shoot me an email at ramon <at> agentmode.co
I've been working on a tool to solve a problem I keep seeing at my day job when handling large-scale deployments and migrations. The āplanā is always scattered across internal docs, spreadsheets, and Slack threads. Coordinating work across multiple teams becomes messy fast
So I'm building Taskplan (https://taskplan.run) - it's like Ansible, but for people. Build a plan, assign tasks to people or teams, and get a real-time dashboard to track progress as the work happens.
I'd love feedback from anyone who deals with the same issues or works on ops-heavy projects.
Chapter (https://jordanful.github.io/chapter/) - a self-hosted ebook reader (server/client) that uses a local TTS AI model for narration. Progress is stored server side, so you can switch from reading to listening anytime.
Cool idea, man. Never heard of the Kokoro model, how's its English performance?
thank you! it's actually unbelievably good. check out the demo audio files here: https://github.com/nazdridoy/kokoro-tts?tab=readme-ov-file#d...
Visually Iām working on a new landing page for phrasing. Itās almost done, just need to record a few videos: https://phrasing.app/next
Behind the scenes Iām rebuilding the sync engine to properly support offline mode. Trying to get to instant opens for the app (and of course work offline). Itās probably my 5th sync engine. Itās been really fun to see how much easier, faster, better, etc each new iteration is.
(And the project at large is https://phrasing.app - a language learning app for polyglots. Itās like anki but designed to be enjoyed)
The short intro video is helpful in understanding what Phrasing does. The promised walk-though video would also be helpful. I am interested in software for aiding language learning, but after reading your original landing page I could not understand what exactly Phrasing is or what it does. I'm looking forward to trying this out some time this week with my target language. Nice work!
Thanks for the kind words! The promised walk through will maybe come hopefully this weekend, give or take a few days.
Can I ask if the new page explained it better? The ādemo/how it worksā section is still missing the graphics, which I think is pretty critical. But Iām hoping the new page is a bit improvement!
One of the pieces of feedback I get most often from users is āoh this is actually really simpleā. But explaining it simply has always eluded me
This looks really interesting! Is it correct that the trial is paid? I've never seen that before :O
Yeah every expression costs money to extract and it's fully bootstrapped. The trial is I give you 10 expressions at cost
Built my own Spotify recommendation egnine after getting tired of Spotifyās repetitive recommendations.
You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better, curated by you version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
It works best if you follow a good amount of artists. Optionally you can get recommendations from artists that belong to playlists you follow or you've created - if you don't follow much or any artists, then you should enable that in order for the service to be useful.

> What are you working on?
Myself, mostly. Trying to wrestle with realizing how much time I've not been spending on my supposedly main project[1] and questioning whether it's really worth doing.
> Any new ideas that you're thinking about?
Way too many. Writing todo lists is part of working on myself.
[1]: PAPER, a pure-Python ~(pip/pipx replacement), from scratch with an emphasis on simplicity and elegance. https://github.com/zahlman/paper . There's more locally that I haven't pushed, including factoring some stuff out into a separate project and planning more of the same. But yeah.
The link to paper documentation seems wrong, it's for some Minecraft server.
Oh, you mean on the badge? Yeah, I made the README from a template that assumes I'd already have the RTD set up, and well I don't. I'll fix that.
Building an AI debugger for embedded systems.
You know that feeling when your microcontroller crashes and you spend 3 hours staring at cryptic registers trying to figure out why? Yeah, I got tired of that.
So I built an MCP server that lets Claude talk directly to GDB. Now instead of manually decoding CFSR registers, I just ask "why did it crash?" and get back "division by zero at line 142 in calculate_average()".
It's pretty satisfying to watch Claude diagnose a deadlock between two RP2040 cores in 10 seconds - something that would've ruined my entire afternoon.
Just shipped v0.1.0: https://github.com/ezulabs/embeddedgdbmcp
A simple HN-like web app that indexes security (and security adjacent) write-ups.
Imagine you, as a security researcher (or any other persona in the security field), wanted to see what prior works are available around bypassing v8 sandbox using webasm, or if whatās been done or found targeting deserialization in Go.
Using this web app, you can search the indexed and tagged write ups.
Also adding MCP support to it so your agents can search too.
Hopefully going live soon.
P.S: I said HN-like, but tbh itās just the UI that looks a bit like HN (Iām not a good designer, so got heavy inspiration from HN listing style), otherwise thereās no other overlap in functionality yet.

Working on https://allscreenshots.com - a screenshot API for developers.
I got frustrated with existing screenshot services choking on cookie banners, rendering half-loaded pages, and serving bloated images. So my co-founder and I built one that auto-dismisses cookie consent dialogs using Playwright heuristics, serves AVIF-first from Cloudflare R2, and supports geo-distributed rendering so you can capture pages as they'd appear from different regions.
Spring Boot + React + PostgreSQL. Bootstrapped after selling a previous ecommerce SaaS.

You have link to the blog series?
thanks. You can read the dev blog here: https://allscreenshots.dev
Hi HN,
Iām working on an API that provides heuristic signals about whether a piece of text is likely LLM-generated.
The system uses an ensemble of techniques, and on my internal evaluation set (details below) it achieves ~99.8% accuracy. Iām fully aware that general-purpose AI text detection is hard and adversarial, so this is meant as a probabilistic signal rather than a definitive classifier.
Thereās a simple demo site: https://checktica.com
And public API docs (no API keys required): https://api.checktica.com/v1/docs
Iād really appreciate critical feedback, especially on:
- Failure modes youāve seen in similar systems
- Whether this framing makes sense at all
- Where such a tool might actually be useful (or useless)
Happy to answer technical questions.
https://finbodhi.com ā It's a personal finance app. It helps you track, understand, benchmark and plan your finances - with double-entry accounting. *You own* your financial data. Itās local-first, syncs across devices, and everythingās encrypted in transit (we do have your email for subscription tracking and analytics). Supports multiple-accounts (track as a family or even as an advisor), multi-currency, a custom sheet/calculator to operate on your accounts (calculate taxes etc) and much more.
Most recently, we added support for benchmarking (create custom dashboards tracking nav and value chart of subsets of your portfolio) and us stocks, etfs etc.
I wrote about benchmarking here: https://finbodhi.com/docs/blog/benchmark-scenarios
NOTE: you can try demo without signup, but it doesn't work in Firefox Incognito mode.
Looks cool! I've had a hard time finding personal finance apps that are e2ee, so this is great.
Only downside is manually importing documents, but there isn't any other way, really, without giving up your data to Plaid or another service.
Most parents I've met understand the internet can be a dangerous place for children but aren't sure what to do about it. Some avoid it altogether, but most give up and resign themselves to whatever happens. What I wanted most was just to have some visibility into what my kids were experiencing, so I built LivingRoom App for iPhone and iPad. It sends occasional screenshots to parents. My hope is that when we shine a light on the online world, we will be free to use the internet as a tool for learning, creativity and connection. https://livingroomapp.com/
Can you explain the part why it's not possible to bypass? Could the kids not simply remove the app?
Have been working on three micro-saas, all built in Elixir/Phoenix:
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.
https://rizz.farm - a lead gen tool for Reddit that focuses on helping instead of selling, to build long-lasting organic traffic.
https://persumi.com - a blogging platform that turns articles into audio, and to showcase your different interests or "personas".
So I'm building this: https://summaryworld.life
It gives you clean text summaries of YouTube videos. There are obviously other tools that do this, but I wanted something that is aligned with actual principles of learning and retention, not just quick TLDRs.
Also added a feature called Related Videos. It extracts the key themes from a video and recommends the top 3 related videos, essentially creating a small āknowledge webā of sorts around the topic. Similar to youtube recommendations, but you don't watch you click and read.
You can do YouTube search directly inside the product. When you click a video, it generates a summary. So youāre still browsing YouTube, but click turns a video into something you can actually consume. Personally found it better way to consume youtube, quicker for me to get through the content I want to consume than have those 10+ Youtube tabs sitting in my browser forever.
Thereās also a public library feature I added where you can make your summary public. Itās kind of fun to see what other people are learning.
Still early, but iterating on it, scratching my own itch.
I'm working on publishing a big update to my open source .NET project, ShopifySharp. I recently finished a custom graphql query builder generator (written in some sloppy F#) which will be included in the next release, which means all of the types, queries and mutations in Shopify's graphql schema will have a matching fluent-style query builder in ShopifySharp.
Aiming to get that published in the next day or two, and then I plan on diving in on a complete rewrite of the book I wrote on building Shopify apps with .NET and C#. It's long overdue, the book still uses Shopify's deprecated rest API and some methods that aren't supported anymore, but I've been holding off on an update until I could rewrite it with the new fluent query builders in ShopifySharp.
Outside of my OSS stuff, I'm continuing working on my SaaS app, Stages (https://getstages.com) [Ā¹], which has been paying my mortgage and bills. Customers have been asking for lots of features lately and I'm anxious to get a particular one finished (filtering orders and events before they come in and are saved to the app) soon. It's my biggest source of churn right now.
[Ā¹] Elevator pitch: the app is like a pizza tracker for your orders that have a custom or long, drawn out production process. Your staff and customers can see exactly where an order is in the process without calling or emailing you. Shopify only for now but one of main dev goals is to move beyond Shopify.
https://beyondwp.io
After around 15 years working with clients and helping them wrangle their WordPress sites, I stopped working with WordPress as a primary platform for building sites.
A while back I've switched to a more modern stack and have fully abandoned WordPress.
Having that background, however, I've come to know (way too well) many of the frustrations and security problems with the WordPress ecosystem. As a result, I started a service to help business owners break free from WordPress on to a more modern Next.js-powered stack that's faster, lighter weight, and easier for them to manage.
Brand new but should be fun!
Gotta say this is pretty cool. Love some of the nostalgia on the homepage.
Personally not a nextjs fan but finding a modern alternative to WP will pay off for many businesses
I'm working on Skyscraper for Bluesky, which is an independent Bluesky client for iPhone, iPad, and the first Bluesky client for Apple Vision Pro.
https://apps.apple.com/us/app/skyscraper-for-bluesky/id67541...
Been a side project for a few months, as I wasn't enjoying the official client, and wanted something that fit my particular tastes (scroll position permanence, greater emphasis on hashtags, support for Shortcuts, and a more iOS-native look and feel).
Launched 3 weeks today, and already nearing 100 subscribers (nearly all annual, but month-to-month also available). Been very fun seeing users start using the app each and every day!
Orchestera (https://orchestera.com/) - Fully managed Apache Spark clusters in your own AWS account with no additonal compute markups, unlike EMR and Databricks.
Currently implemented the following:
- Automated scale in / scale out of nodes for Spark executors and drivers via Karpenter
- Jupyter notebook integration that works as a Spark driver for quick iteration and prototyping
- A simple JSON based IAM permissions managementent via AWS Parameter Store
Work-in-progress this month:
- Jupyterhub based Spark notebook provisioning
- Spark History Server
- Spark History Server MCP support with chat interface to support Spark pipeline debugging and diagnostics
Open to feedback and connecting. Docs at https://docs.orchestera.com/
I've been having a lot of fun building https://vgstack.app
It's yet another video game backlog tracking service but I'm building this one to automate as much as I can about the actual game logging process. So for example, I'm auto-forwarding all my Nintendo and PlayStation purchase emails to a custom inbox. That email gets parsed, the game(s) and date(s) are extracted, and I get a new queue item I can approve or deny easily on my phone. It also has a documented CRUD API for easy integration for other services (like Zapier).
Yes, it also has a chatbot... I've been toying with a natural language interface for quick actions like "just beat TOTK" to mark Zelda: Tears of the Kingdom as "beaten". It's a bring-your-own-Gemini-key approach... So far, its working pretty well for me. It also supports basic questions about your game library and history that would be tricky to represent without a lot of filtering options. Like for example, "How many Switch games did I beat between March and July of 2024?". Fun stuff like that.
Tech stack is Django/HTMX/Alpine/DaisyUI/Postgres/self-hosted.
If you decide to try it out, I'd love your feedback! There's a quick in-product feedback widget on the bottom-left which sends me an email :)
Working on https://github.com/wiseprobe/patchpal , an open-source agentic coding assistant in Python.
While it's true that the agentic coding assistant space is crowded (Claude Code, Aider, Opencode, Codex, etc.), we needed something supporting both local and cloud models that we could easily modify/extend for custom workflows.
Being able to access the agent through both a terminal and a Python API/REPL has come in handy.
Recent releases includes custom tools, agent skills, and built-in support for Ralph Wiggum loops.
https://catchditto.site
I'm building Ditto ā it clones websites with 100% visual accuracy and outputs a proper React app with named components and preserved structure.
The problem: you find a design you love, want to use it as a starting point, and your options are either manually recreating it or using a tool that spits out a tangled mess of divs and inline styles. CatchDitto gives you an actual codebase ā clean component hierarchy, sensible naming, structure you can extend without wanting to rewrite everything first.
I'm still iterating, would love to hear what others think.
Iām working on an open source CLI that experiments with governance at inference time for autonomous systems.
The idea is to let multiple agents propose, critique, and stake on decisions before a single action is taken, rather than letting one model silently decide. Itās model-agnostic and runs locally, with no blockchain or financial layer involved.
Iām mostly exploring whether adding explicit disagreement and cost at decision time actually improves outcomes in high-stakes or automated workflows.
https://github.com/consensus-tools/consensus-tools
I've also created an AgentSkill to interact with the cli:
https://github.com/kaicianflone/consensus-interact
I launched https://rebrain.gg/ a few days ago.
It's a bit like Reddit but focused on learning. (Doom learning instead of doom scrolling)
You 1) upload a source 2) direct the kind of questions you want to be asked 3) start answering (and if you get the answers wrong, you can discuss the problem with "AI").
You can read other people's sources, questions, answers and their discussions with AI too.
And if you're learning the same thing as other people, you can join communities to share sources/questions.
It's still very early on, so I'm very interested in any feedback.
Iām building PointWiseSystem, a browser-based habit and responsibility system I originally built for my own family.
It uses a simple points model instead of streaks or financial-style tracking to make expectations visible, progress clear, and follow-through easier.
In real use itās solving three main problems: - As a Family Chore Chart ā a digital chore system that actually gets kids engaged with responsibilities using points and rewards. - As a Personal Habit Tracker ā a way for individuals to organize routines, add notes, and earn points toward meaningful self-defined rewards. - As Complete Homeschool Management ā tracking assignments, logging progress by subject, and generating reports and transcripts for multiple students.
Itās entirely web-based (no app download) and works on phones, tablets, and desktops. Iām actively iterating on it based on real use, and itās been most useful in situations where simpler systems actually get used instead of abandoned.

I was teaching coding to my 10yr old and we were talking about creative projects on the internet. That led to discussing the Million Dollar Homepage and why something that simple worked. He asked: could we build something similar today? That curiosity turned into moltbillboard.com ā a simple public billboard, but born in the era of AI agents (inspired by the recent OpenClaw craze). Itās just an experiment..
I am working on my first multilingual word game: https://changeword.org
My previous games have all been exclusively in English, but this one also has Spanish, French, German, Dutch and Swedish. It's a take on the classic word ladder game, with golf scoring mechanics.
Still needs a bit of fine-tuning for the word lists and puzzle generation, but I think it's already pretty playable. :)
Solar-powered data center in a desert.
Fully off-grid using solar, batteries and Starlink for uplink. Focusing on AI inference at the beginning. Currently building our first prototype and testing cooling solutions.

How will you cool it? Will it be under ground? Iāve often thought about this as we have space and sunlight.
Building, "Workloom ( https://workloom.so )" - a free-to-use project management tool for freelancers and small teams.

Forge ā A 3 MB Rust binary that coordinates multiple AI coding agents via MCP https://github.com/nxtg-ai/forge-orchestrator
Forge is an orchestration layer that sits between AI coding tools and your codebase. It's a single Rust binary (~3 MB, zero runtime deps) that runs as an MCP server over stdio. Any MCP-compatible AI tool can call it.
MIT licensed. Whitepaper with the full architecture: https://nxtg.ai/insights/forge-whitepaper
ragextract.com
A document RAG API based on multimodal embeddings that's intended for data extraction. If your document workflow involves search and you're looking for ways to cut down on VLM (OCR) costs, Ragextract provides a simpler alternative (less bells & whistles) which makes sense for startups, SMEs and freelancers.
As someone who works on AI document workflows, I use Ragextract myself to reliably execute for various clients in finance, insurance and proptech. I'm currently working on marketing/messaging for the service and could do with more feedback and use-cases.
Have a new or existing project which could use something like Ragextract? Email me and if there's a fit happy to provide a demo or free subscription.

Working on reproducible test runs to catch quality issues from LLM providers.
My main goal is not just a "the model made code, yay!" setup, but verifiable outputs that can show degradation as percentages.
i.e. have the model make something like a connect 4 engine, and then run it through a lot of tests to see how "valid" it's solution is. Then score that solution as NN/100% accurate. Then do many runs of the same test at a fixed interval.
I have ~10 tests like this so far, working on more.
Sounds really interesting. What are you using for the tests/reports?
Nice. Sounds like will converge to QA as a Service

An all-in-one operations workspace that starts with forms but doesnāt stop there.
teams (especially HR and ops in small/medium companies) need to launch and operate fast, but the moment data comes in, everything falls apart into spreadsheets, emails, and half-used tools. the real work starts after collecting data.
What weāre building:
Form & workflow engine, and backoffice layer on top of submissions: tasks, assignments, reminders, budgets, client/contact directories, inventories, meetings, internal knowledge base.
Operational add-ons: quizzes & assessments, certificate generation, invoicing, document repository, reusable email templates, Anomalies module.
Itās less āTypeform competitorā and more āwhat happens after the formā, for HR teams, marketing teams, and SMEs that want one calm, predictable system instead of a tool stack.
(weāre Morocco/EU-oriented).
Still super early (one month), shipping steadily.

I'm a solo dev founder working on Potniq (https://potniq.com) - a business travel tool that tells you exactly when to leave based on your entire itinerary.
I used to work in devrel, and traveled a lot for events, and I always struggled skipping things like workouts, looking at the time on the last day of a conference trying to check whether it's time to leave yet - so this gives me the opportunity to build a tool I would have loved to use.
Currently I'm working on a LLM-powered booking email parser, that ingests forwarded booking confirmations and adds flights, hotels, etc. to your itinerary.
I am getting the AI Agents to build an expense tracker Telegram. I would like to have one myself and among my family members since we are heavy Telegram users. I am also using this as a way to learn more about the AI Agents (what they are good at, their limitations, etc) with (hopefully) proper guardrails, guidelines, checks, etc.
https://github.com/yelinaung/expense-bot/
https://gitlab.com/yelinaung/expense-bot/
As you may see from the git history and "contributors", it's mostly Claude and AMP making the changes. I am not entirely sold on these agents and not particularly excited by these. But I also feel that I can't afford to sit out this transition so here I am...
Iām building Historic, a private AI video journal for founders.
You record short morning, evening, or ad hoc sessions, and it transcribes and indexes them into a searchable archive of your thinking. It uses simple Apple Fitnessāstyle rings to encourage consistency, plus monthly insight reports and suggested ābuild in publicā posts.
I built it because notes apps werenāt capturing my thinking in full fidelity. Using Reflect I averaged ~65k words per year. With Historic I logged ~85k words in one month.
Your thoughts are already your most valuable asset. Historic just makes them accessible.
https://historic.app
Iām using Whisper Memos (https://whispermemos.com) for this exact use case - is this meant to be a more tailored version specifically for founders?
I'm working on Lightningbeam (https://lightningbeam.org), an integrated multimedia editor. It's inspired mainly by Macromedia Flash, Apple GarageBand, and Kdenlive. It combines animation, audio and video editing into a single timeline. It's cross-platform, running natively on Linux, macOS and Windows.
I'm currently rewriting the UI in Rust - previously it had a Rust backend and a JS frontend using Tauri, but I ran into bandwidth limitations which prevented it from being really usable as a video editor. It's currently in early alpha.
Keep working on a GUI calendar for Linux which would CLI users happy to use https://semana.alexmarkov.xyz/. Just recently I've shaped the architecture a bit.
Finding work after a corporate restructure. Also migrating my workloads from VMs and strewn-about containers onto a Talos K8s node, so I can break the cycle of bespoke builds at home and get back to enjoying projects.
Speaking of projects, Iām roughing out a method of pulling cost data for common services (compute, storage, databases, etc) across the three major cloud providers and making recommendations as to where to put things for optimal cost; a key component of a āuniversal cloudā idea Iāve been kicking around since 2020 or so, where the base cloud services are abstracted away into commodities rather than bespoke products or locked-in vendors. The goal is to basically have something like Terraform that will transpose its code to the destination cloud chosen by the cost analyzer at execution, and eventually auto-migrate load as prices or needs change (e.g., a client churning early and shifting that reserved instance to another customer for a higher margin).
Write once, and trust the pricing model to deploy it where it makes the most fiscal sense. No more learning Azure/GCP/AWS for bog-standard workloads anymore.
Delving deep into novel ways to extend Excel and make it more accessible. Perhaps different approach to copilot in that AI is only used during authoring, the yielded output being a standalone artifact.
The result is https://xllify.com
It embeds Luau which tames the very old school C SDK. This means that the same code can run as native add-ins on Windows (XLL) and the more modern-but-far-slower web engine, thanks to WASM. Luau is safe and fast.
The exact same bytecode runs in both styles of add-in. You get the performance of native with no extra work. Many approaches for writing custom functions are unacceptably slow, particularly when their inputs come from fast moving realtime data feeds.
I know Luau is perhaps a left-field choice. However, coupled with a coding assistant and bringing that lightweight conversational dev experience right into Excel (xllify Assistant is an add-in itself) this is perhaps less of a barrier.
It's still in beta but I repackaged Descent Raytracer (a remaster of Descent (1995) made by students at Breda University) to be launchable on macs with Apple Silicon (ray tracing reqs M3+).

Iāve been working on something we call the Functional Universe (FU), a modeling framework and experimental codebase that treats systems as sequences of irreversible functional transitions, rather than objects evolving against a global clock.
It started as a computational experiment, but itās been interesting how naturally it lines up with ideas from QM (aggregation vs collapse), relativity (proper time), and distributed systems (event-driven causality). Still very much a work in progress, but already useful as a way to think clearly about time, causality, and scheduling in real systems.

A chant synchronization app for large protests and events https://wordsunite.us
Over the last few weeks Iāve been building Pointless (https://pointless.cards), a Planning Poker webapp thatās both frictionless (no sign up) and actually fun!
Iām trying to embody the experience of a JackBox game into a Scrum ceremony that should be lightweight but is often painful and tedious. Iāve also gotten to learn a lot about Cloudflare Durable Objects building this and have been delighted with how easy they (and PartyKit) make building multiplayer apps like this.
Itās completely free (I plan to keep it that way) and full of easter eggs and delightful jokes at the expense of Jira and modern software development, of course. If your team is following Scrum and could use a bit more joy in the process you should check it out!
https://github.com/stacktape/stacktape
An alternative to tools lik sst.dev or serverless framework, or a PaaS services like Render.com or Flightcontrol.
Deploys to user's own AWS. IaC-first. Has a PaaS-like console UI.
The best features: auto-generates IaC config by scanning your code. Has built-in EC2 runner which is 2-6x faster than AWS CodeBuild.
We've now also implemented dev mode, which is similar to SST. It deploys parts of the stacks that can't be locally emulated (lambda functions, cognito, etc.) with fast re-deploy, and emulates everything else (containers, SQL databases, Redis, DynamoDb, etc.) locally. This means testing/developing is pretty much free, and you have the fastest feedback loops possible.
Whole Stacktape, and dev mode in particular is also very optimized for coding agents with `--agent` flag.
To try it, run `npx stacktape init`
EDIT: Changed the link to github. Stacktape core is now open-source.
I have a spring/react jar.
Previously I built a jar/docker and deployed to a common server. Fine.
Can this service deploy this to AWS free tier? Will it "know" how to avoid any paid services? (I don't necessarily need a docker or even permanent storage yet)
EDIT: Also - charging a % of AWS bill is pretty wild...
The cheapest way to deploy a container accessible over HTTP is to use web-service resource (which uses AWS ECS loadbalanced with HTTP-Api-Gateway, which is pay-per-use) and use EC2 launch type (cheapest instances are only a few $). Not sure if it's still under AWS free tier, but definitely not expensive.
Regarding charing % of AWS bill - yes, we're changing that soon. It's going to be flat fee + 10% of AWS bill.
Our free tier covers 90% of vibecoder, freelancer and side-project use-cases though. So probably nothing to worry about unless you're a 2+ person business. And at that point, it's still far less expensive than having a DevOps person or learning all of the 150,000 AWS loopholes yourself.
Cross-platform book management and reading application: https://github.com/Eoic/Papyrus.
This isn't a serious project by any means, but rather a prototype. Also, I really got carried away using Claude Code, although my initial goal was simply to glue a quick proof-of-concept and see how it could look like.

Dimensionally accurate AI 3D modelling. My grandpa has a 3D printer but struggles to use any complex tools. So I am working on this chat interface to allow him to do some simple models.
So far he has triggered more than 150 generations. Itās getting better every model cycle and gives me something I enjoy working on.
Really cool! I tried to make this part I've been wanting but I think forcing myself to clearly describe it made me realize there is a simpler way.
Building better quality cadastral data on all of Italy for a client, pretty fun postgis work. Fuzzy string matching of government records, OSM, proprietary data and aerial remote sensing data ran through an ML pipeline.
Working on migration from Modal to a single nvidia jetson, to do low-cost monitoring of toxic emissions at the local tata steel plant. Ran this pro bono for the last 2 years, the fun is in getting this as cheap as possible but still with good accuracy
Building a SSTV ios app - you can encode images in sound and transmit these over (ham) radio. The ISS regularly broadcasts these too. And building a multi-user IRC-like chatroom over audio. Hook up your mac or ipad to a voice radio channel, and chat over very slow (31 baud) but very resilient links.
Building pkgstore.io, a marketplace for commercial .NET NuGet packages.
https://www.pkgstore.io
NuGet.org doesn't distinguish between a hobby project and a professionally maintained library with real support. pkgstore is a curated directory and marketplace where publishers can sell NuGet packages directly, with full dotnet push/restore support, Stripe payments, and automated access control.
In open beta now, onboarding publishers. Would love feedback.

This month is dropping network cable to the home offices and then adding recessed lighting in the living room, pantry, and coat closet.
Next month prep starts for finding dev work after an extended hiatus.
Dots Journal, a privacy focused lifestyle tracker for iOS.
https://dotsjournal.app
Iāve been suffering from migraines for the past few years and wanted a dead simple way to log when they happen, as well as any other contributing factors I could think of. Inspired by the simplicity of spreadsheets, I built a grid of events, and as you tap on cells, you log ādotsā. Those dots, over time, reveal patterns.
Iāve already identified several contributing factors to my migraine triggers using it. Itās been so genuinely useful I wanted to share it with others hoping they might also benefit.
The next big release is coming out later this week which includes visualizations, charts, and on-device analysis of your journal to provide insights.
I am building QuietReads (quietreads.com) - a single-player book tracking app with an AI assistant.
I got tired of the gamification and social elements of Goodreads, StoryGraph and others. I don't care too much about reviews, but do care about engaging deeply with what I am reading.
Lot's to do still: - Refining the experimental MCP integration so I can bring my bookshelf into my AI assistants - OCR to build notes from screenshots - Voice notes
I wrote a little about why I am building the app here: quietreads.com/about Thoughts on building the app: https://thinking.luhar.org/2026/01/building-at-the-speed-of-...
I'm working on a search engine for clinical trials around the world.
I was frustrated by the process of searching for clinical trial info using the clunky and slow registry websites. So I aggregated all trials around the world and made the search faster. Additional features:
- You can watch a trial and get email updates
- Sometimes a trial is done and a paper published, but no updates to the official page. I try to find these papers and link them
- I try to link trials with the same drug together, showing the drug going through different phases
https://findtrial.co/
I continue with my suite of mobile apps for parents:
* https://screenspy.app - observe what youd child is doing on desktop PC. Roblox or homework?
* https://weblock.online - a VERY restricted, whitelist-first mobile browser for kids, use it instead of Safari. I want to feel calm when my children browse the web.
This is very useful given that children today are increasingly exposed to and navigating online environments.
https://github.com/tldev/posturr
Posturr is a macOS app that blurs your screen when you slouch. Iāve always had bad posture at my desk, so I wanted to figure out a way to check myself. This idea is not radically new, but the methods by which Posturr reminds, e.g. blurring screen, colored border, is unique and effective.
Recently released to the App Store at: https://apps.apple.com/us/app/posturr-posture-monitor/id6758...
I'm still plugging away on my PostScript interpreter. Right now I'm working on the clip and eoclip operators which has turned out to be much more complex than I expected. Mostly because I am not using any 3rd party libraries nor any AI generated code.
On the house front I'm just about to install an IKEA kitchen.
I've been working on a security model and architecture to make a hardened rewrite of OpenClaw. I've got a first pass of prompt injection and secret exfiltration protection and an agentd that gives network vm/sandbox access, reads the accessibility tree and can take screenshots of apps or regions of the desktop. I also have full policy control in place with OPA so you can manage everything the agent can do in one place.
The goal is a milspec, zero-trust autonomous agent that can be completely locked down. I'm also tying the agent's heartbeat into activitywatch so it can be a good personal assistant and do stuff for you pre-emptively based on your stated goals and session activity.
Semi-academic attempt to build semantic-level standard system for data type classification. Useful for metadata semantics data lakes / warehouses beyond basic physical level like text/number, with assumption that it may be useful for AI-targeted metadata, your text to sql cases. https://github.com/jaakla/semantic-field-types
Ive been working on Kettle, it is a language for quantum-classical computing
https://kettle-lang.pages.dev
I find quantum mechanics fascinating and wanted a better way to play with it. Linear types prevent copying qubits, effects track what's quantum vs pure. The type system catches mistakes that would otherwise blow up at runtime.
Runs on a local simulator (with various qubit types modelled) or IBM hardware (sort of). Still a research and learning language for me - I break things regularly.
If any real quantum physicists are lurking, Id love to hear what Ive got wrong!
Working on https://dataraven.io/ ā a low-cost, cloud-native data movement platform focused on object storage.

Im working on ebpfence https://github.com/CucumisSativus/ebpfence
I want to create a tool that would automatically block the stealers from stealing your previous credentials or crypto wallets. I had this idea after the Shai-Hulud attack
It's an experimental side project, but so far it looks very promising.
StoryStarling - Turn your story idea into a printed children's book
https://storystarling.com
Working on a platform where you describe a story concept and it becomes a real, illustrated picture book - professionally printed and shipped to your door.
The key difference from "personalized" book companies: this isn't template stories with a name swapped in. You bring an idea - maybe a book about a kid with a cochlear implant going to their first day of school, or a bilingual German-Turkish story about visiting grandma's village - and it generates a complete original narrative with consistent illustrations throughout.
You can upload reference photos so characters actually look like your child. Supports 30+ languages including bilingual editions on the same page.
Currently refining the showcase features and adding RTL language support.
I too was thinking about something like this a few months ago. There were couple of reasons I didn't pursue the idea. One, the image generation AI wasn't reliable enough. Like, I couldn't get it to generate 2 images where the characters looked consistent, let alone a book worth of images. Two, the margins were quite small, so didn't seem like a viable business.
Wondering if you've thought about such things and your perspective.
Character consistency was the hardest problem, and honestly what took the longest to get right. We use reference images as style anchors, run multiple generation passes, and have an LLM "critic" that checks for visual inconsistencies and triggers regeneration when needed. It's not perfect but it's gotten to the point where parents are happy with the results.
On margins - tight but workable.
What do you mean by RTL because all I can come up with is Verilog or VHDL and I'm certain that's not your meaning. I'll try it out. I have a children's book story I've been trying to image generate for 3 years now and it's not yet worked out. I think the primary reason it fails is that the scenery I request is lifelike yet extremely rare to actually see, although, I did see it, and that's what inspires the story.
RTL = Right-to-Left languages - Arabic, Hebrew, Farsi, Urdu. The text rendering and page layout needs to flip for these, and it gets especially tricky with bilingual books where one language is RTL and the other is LTR.
What's the scenery? Happy to try it on our system if you want to share.
This is really cool. I wish the example stories let me see the entire book and purchase them if I like them.
Iām skeptical about the stories being good quality so seeing the full stories might mitigate that.
The story synopsis next to the preview gives you the full narrative arc before you commit. But fair point on wanting to see more.
You can edit or regenerate pages if something isn't working - it's iterative, not one-shot. Happy to help you try it out without payment - drop me an email.

Iāve just published the first public release of a new open source project Shovel.js, replacing tools like Express, Fastify, Next.js, Vite. Itās a full-stack/meta server framework which implements the full Service Worker specification but in Node, Bun, Cloudflare. It leans into using web standards to do things like accessing the filesystem, reading cookies, create client-side bundles rather than inventing new APIs. You can read about the process of making Shovel with AI in the introductory blog post.

I'm building a safer Agent system for SMBs.
The biggest problem is internal knowledge and external knowledge systems are completely different. One reason internal knowledge is different it is very specific business context and/or it's value prop for the business that allows charging clients for access.
To bridge this gap, the best approach is to train agents to your use case. Agents need to be students -> interns -> supervised -> independent before they can be useeful for your business.
https://github.com/rush86999/atom . it's still in alpha.
I just proved that constraint solving problems can be encoded as p-adic linear regression problems[+], and that therefore we can use machine learning optimisation techniques to get exact answers.
So of course no journal or conference is in the least bit interested, and I'm now reformatting it for another obscure low-tier journal that no-one will ever read.
Otherwise:
- automating the translation of a Byzantine Greek work that has never been translated into English before. https://stephanos.symmachus.org
- also preparing evidence for a case against the university I sometimes work for.

I'm building Banger, a work email platform for builders (service + apps). It helps you to:
-> host your own custom domains and plug existing email sources with privacy;
-> share mailboxes with teammates and AI agents without having to share pwds as in the 80's;
-> git review like UX to collaborate with humans and AI agents; local AI to save money on mundane email tasks;
-> native apps + cli/mcp/api with guardrails for external AI agent access

https://reposit.bot/
Having done a lot of back and forth with LLMs and at the end throwing away learnings from a conversation felt so wasteful - reposit allows you to /share a summary of the valuable learning from your LLM chat for others to discover.
At the beginning of researching a problem, your agent can search reposit just like Context7 for docs. This way, even if you opt out of sharing your data with your LLM provider (as it's all or nothing), you can choose to publicise a solution to your problem with very little effort.
I'm working on extracting valuable learnings from open-source community projects as a starting point now (with attribution), as it probably needs a larger database to be valuable for users to install and use.
You can also self-host it and share privately within the company.
I'm working on PC Part Picker for hi-fi stereo gear. https://buildhifi.com
Some technical highlights:
- Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains)
- Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference
- Rule engine: Pluggable rules check completeness, power matching, phono stage requirements, DAC needs, and more
It's getting close. I'll do a show HN on it sometime soon.
This is fun! I put my (slightly oddly setup) system into it but I couldn't reconfigure which set of speakers were connected to which amp, or reorder the signal chain at all. Is this a planned feature? E.g. I have an integrated all-in-one amp that drives my main speakers but I tap off the pre-amp output into a secondary integrated amp that drives two secondary sets of speakers but your app assumed that my second amp was driving all six speakers and so spat out a warning about power levels...
Thanks for trying it out. I've got the signal chain and messaging handling most setups well. This is pretty novel. I'll see about handling it.
Do you have a link to this config you would share with me? Use the Share Config at the type right of the builder to get a portable URL anyone can use.
Cool! Couldn't add my Sonus Faber Venere 3.0, maybe they are too old (2017)
I'm still building out the catalog. This will be going on forever. I can add them.
I added them.
I built a mobile app for golfers who don't like using their phones while they play. Take a picture of your scorecard after the round and it reads/saves the scores and stats (and allows you to post to the USGA if you keep your handicap).
I'm a self-taught coder who first built this 7(!) years ago but couldn't figure out the OCR part. Started again 9 months ago on Replit (starting with Agent 2 which was okay, then eventually starting to absolutely crank with Agent 3) and it works really well now.
Would love feedback from any golfers! golfrise.com
I'm working on ArkWatch (https://watch.arkforge.fr) - a monitoring API that you can use with just curl, no signup required.
The insight: most solo founders need basic "alert me when this changes" monitoring, but existing tools force you through signup flows, credit cards, dashboards you'll never use. So I made it dead simple:
That's it. It watches the URL and emails you when content changes. Free tier = 10 checks/day, which is enough for most side projects.I built this because I kept forgetting to monitor my own stuff. Now it's live and I'm trying to get my first 5 beta testers. The challenge is marketing - I'm a developer, not a growth hacker. Learning as I go!
What's been your biggest challenge with your current project?
Currently working on:
https://vimgolf.ai
To show newbies how to use vim. Currently its not complete and has major issues. So if you want to try give it a go, but please hold your judgement as not all shortcuts have been added.
We ran into the annoying Envoy 503 bug in our prod and needed some quick tools to help figure out what was going on with TCP connections and HTTP requests.
https://github.com/vishnugt/TCPFinMonitor. Live - https://keepalive.gt.ms/
This tool tracks TCP FIN packet timing to see how upstream connections are closing and how keep-alives behave. It helped me spot when connections were closing too early or timing out, which was causing those 503 errors.

A fast, minimal httpbin clone written in Rust. Itās way faster(20x throughput) than the usual httpbin and useful for testing HTTP clients and debugging requests without extra noise.
These arenāt polished, just some stuff I needed to iron out the issue.
I'm working on a macOS app that identifies music playing around you, constantly. You can scrobble them to Last.fm, ListenBrainz, LB-compatible sites, a Mastodon account, local Shortcuts workflows, and/or or local files. It also support Apple Music and Deezer.
I built it because most scrobblers only keep track of Apple Music or Spotify plays, but I have streaming stations on all day long, or the radio is on, and those never make it into my playing charts or recommendations etc.
Early days, more to come, public beta is ongoing, and I am looking for testers :)

I built meepr recently. It's basically twitter v1, but the hashtag system is gated, it builds a knowledge base of what you talk about and how deeply, and then enables you to post into/create hashtags, think of twitter meets reddit meets quora? Feel free to follow me and share with your friends. No recommendations, no algorithmic timeline, no ads etc. Just regular old micro-blogging with a small twist. https://meepr.co/je
The other thing I built but am less interested in personally just through should exist, is something like MoltBook but for more formal topics like the sciences. -> https://ideas.gd/
Been dedicating some free time from my weekends to sending PRs the DarkRadiant project: https://github.com/codereader/DarkRadiant
DarkRadiant is open source, cross platform level editor for The Dark Mod and other idTech4 games like Doom 3, Quake 4 and Prey. It is a lot of fun to add features that make level designers more productive. I would like to invite anyone that is curious about wxWidgets, CSG and game dev to join us.
If you are a designer, we could definitely use a new icon set.
I spent about a week, writing this[0].
Itās a special UIKit map package, designed to be integrated into SwiftUI, as map support is a big SwiftUI Achilles heel.
I have integrated it into another package (a SwiftUI admin tool, that isnāt public), and it works exactly as I planned.
I often do this kind of thing. If I can break some module out of my work, and publish it, I spend the extra time, polishing and documenting it. No one else really cares, but it forces me to do a really good job, so I get an extremely high-Quality component, that I donāt have to worry about, later.

Interesting! I've recently plumped for UIKit (with bits of SwiftUI dropped in) for a new mapping app because, as you say, SwiftUI map support is virtually non-existent. Have you thought about adding Maplibre support as an alternative to MapKit?
I try to use MapKit, when possible, as it is unencumbered by licensing and support issues (and works pretty well), but I have considered MapBox. Itās commercial, but pretty straightforward, with licensing and support. I have heard good things about it.
I donāt really know about Maplibre (but Iāll check it out).
Had a friend create an app, based on Google Maps (if you remember, in Ye Days of Yore, GM was the mapping engine for iOS), but Google did the licensing rug-pull thing, and he had to do an emergency open-heart surgery to his app.
That was a sobering lesson about relying on third-party dependencies.
[EDIT] Looking at your app, Iāll not be surprised, if youāre familiar with my friendās app: EasyRoute
I replaced MyFitnessPal: https://macros.jlcarveth.dev
Uses vision models to allow for automatic scanning of nutrition tables. Supports UPCs. Still thinking of a good name.
I also made an RPG game via a discord bot: https://questforge.ca
Indiehacking so couple of serious things and then some just starting out and some mostly for myself.
Serious ones making over 2k/mo https://bestphoto.ai/ - AI Img/Video tools https://aieasypic.com - Original version of above, still making some money
New things not making money yet https://admakeai.com - AI ads generator for facebook ads. Made mostly so I have a easy way to prompt for stuff and keep track of good AI ad prompts. Have been using it to make static image ads for BestPhoto and actually have over 40 conversions at $~45/conv. Pretty good considering my previous attempts with my own handmade ads using canva was like $80-100/conv. but most of the time FB wouldn't even spend anything from my budget before
Fun stuff/for myself:
https://xhdr.org/ - Made like a few months back when twitter was allowing HDR images in your profile pictures, they patched it like a week later, but was fun while it lasted. Still works for facebook, keeping it up for FB video ads, I've noticed people abusing this a lot when scrolling on FB recently searching for good ads, so I'm guessing it works? Good way to get attention of people on iphone quick
https://framecall.com - Saw people making cool AI motion videos using the claude code skill with remotion, so packaged it into an actual web app you can use as a chat instead of through terminal. Harder than expected to get all the tool calling(and auto continue) stuff to work, similar to how claude code works
TranslateVoice(name TBD) - An iphone voice translate app where you tap microphone button and it uses 4o realtime to translate between you and someone else. This was originally one of the biggest thing I was hyped about as a usecase when 4o released but when I tried it on their app, it just didn't do prompt following well at all it would randomly try to communicate with the user instead of strictly translating, just randomly cutting off someone before they finish speaking etc. Currently have 3 modes that work, that if no one else uses I will be using:
1. Interpreter mode: Basically User 1 speaks to phone in their language, phone talks to user 2 in their language, user 2 replies to phone in their language, phone replies to user 1 in their language etc. Just pure translation, with chat history transcribed in each other's language
2. "Friend mode": You tell it a general goal, "I want to get immigration documents, I need to know the requirements" it then basically acts as if its a friend you called to help with translation and gathers everything while talking back and forth with User 2 and then at the end goes back to user 1 with all the info.
3. Stealth mode: Airpods in, it will transcribe and translate everything being spoken and tell you what to say based on initial goal or you can also write extra instructions in the chat. This is currently the only non-working/buggy one I'm trying to figure out before releasing this, since both will be speaking in same language its hard for model to know who is user 1 and who is user 2 automatically.
First time I'm creating an Iphone app fully vibecoded(react native so I understand whats going on frontend wise at least cause of react). Not looking forward to the app store review process. And I know this is likely something someone already made but its probably paid and I have like $25k in Azure credits I can burn anyways.
Cascade Puzzle, a daily puzzle game inspired by Panel de Pon / Tetris Attack. Swap blocks horizontally to match 3+, trigger chain reactions, clear the board in limited moves.
I originally started this years ago and abandoned it because puzzle generation was hard and I didn't have the proper time to finish it. Picked it back up recently with Claude Code and finally cracked it, the generator uses backward construction (starts solved, reverses moves) so every puzzle is guaranteed solvable.
3 daily puzzles (Easy/Medium/Hard), shareable results like Wordle, no account needed.

I'm making a suite of simple Windows tray apps that do just one thing. They often have existing equivalents but I think my version is better and/or simpler ;-) All work starting with Win7.
The first three are:
- miniWake: keeps the computer awake
Alternatives: Powertools; USB mouse jigglers
Features: installs without admin rights; triggers invisible mouse events; turns off at LOCK, turns back on at LOCKOFF (saves battery); manual turn off or on via double-click on the icon
- miniRec: records system audio + microphone to mp3/wav
Alternatives: various utilities like Voicemeter, AudioRouter, or some DAWs
Features: does not require any special driver; installs without admin rights; light on resources; "invisible" to third parties (video meetings); auto turn off after 5 minutes of silence (configurable)
- miniCron: system scheduler as a service
Alternatives: NSSM - the Non-Sucking Service Manager; Splinterware
Features: launches any program at any given time (cron like but without cron syntax); kills the current task when the service is stopped; reads and logs stdin/stderr; very light on ressources and very simple
Two others are in the works.
I just posted my recorder app that does the same thing. I use NAudio WasapiLoopbackCapture. it's written in C#
Ah yes, it's a good idea to record microphone and system audio to different files but I ruled against it for simplicity's sake. I wonder how you deal with offset, esp. when the mic comes from a Bluetooth headset? I added an offset option in the config file as this can be up to 2000 ms (2s) in my tests! Also, a console app may frighten the non-technical, casual user?
But anyway, great minds think alike I guess! ;-)
Flora Carta - https://floracarta.com
A tool to "Design and keep track of gardens, orchards, and landscape projects."
It's very alpha right now, so its quite ugly, but people are already using it. I'm committed to releasing early and often.

Built ShelfSwap (https://shelfswap.io). I enjoy reading, but books are getting expensive, and many of us already have shelves of good books weāre done with. This is a simple platform to swap physical books and connect with other readers.
I used this as a real end-to-end project to sharpen my backend skills in Go (API design, data modeling, deployment), while also experimenting with AI-assisted development. Itās live, and Iāve already made a few organic connections through it.
Would be cool to auto-sync with existing book management tools like clz.com/books. Also, are swaps mutual exchanges, or are members giving books away with nothing in return?
Nice. Swaps are ideally to be mutual exchanges, so that everyone has 'skin in the game'
I an building Bloomberry, an alternative to tools like Wappalyzer.
It helps sales teams find companies that use any product/technology, but not limited to frontend tecnologies.

I've been working through the pwn.college curriculum, as well as building https://stoacentral.com. It's meant to be a place to chill, discuss philosophy (Stoicism), and improve yourself. I built it after becoming annoyed with Facebook groups, really.
If you're interested in Stoicism, feel free to join and start some discussions.
I am working on a e-commerce and pos solution. More like shopify/saleor/woocommerce etc. with ready to start for small businesses selling physical and online and in-store products and services.
The platform itself is built on elysiajs/bun and tanstack and is completely hosted in EU and the payment processor is a EU based entity and we have an ISV partnership.
I am trying to make a cheaper, straightforward easier to use observability platform with a good core offering without going overboard on features. Based in Europe.

vibebin is a self-hosted platform for running persistent, isolated AI coding sandboxes on a single VPS using Incus/LXC containers:
https://github.com/jgbrwn/vibebin
It automates installing and managing Incus, Caddy, and SSHPiper, provides a TUI for container lifecycle and quick actions, a web admin (built/compiled on the container) for toggling and updating AI coding tools (Shelley, Claude Code, OpenCode, etc.), and a background sync daemon that keeps Caddy routes and container metadata in sync.
Each container exposes coding tool web UIs on isolated ports and supports direct SSH/VS Code Remote access, so you can run multiple independent coding agents against real project files without exposing your local machine.
The project emphasizes simplicity and recoverability for running agents locally: containers are persistent, optionally routed via reverse proxy with basic auth, and tracked in an SQLite DB so setups auto-heal after restarts. Itās written in Go, includes an install script for one-line deployment, targets modest VPS specs (4ā8GB RAM recommended), and bundles helpers for DNS and provider automation.
Ideal if you want a lightweight, opinionated way to host multiple isolated AI dev environments on your own server instead of relying on hosted agent platforms.
Looks really interesting but is the entire project ~5K lines of Go in one file? Don't you find that hard to read or are you purely vibecoding this?
> This project is 99.9% vibe-coded on the exe.dev platform using their Shelley Web AI Coding Agent and Claude Opus 4.5. Take that as you will.
Ah, wait - should've read the README before commenting. /facepalm
Thanks for sharing the project - will try it out!
I use it and it works well for me but there's likely plenty of bugs. Needs a lot of testing so any feedback or issues from anyone would be great.
Since we recently moved out of the city and into the mountains of Switzerland, I had a niche problem... agreeing with my buddies which is the best ski field to meet at when we all live in different towns. So I made a little web app to help:
https://skicompromise.ch
This was a fun little project I did over the Christmas holidays but only finished off recently. Basically I precalculated the public transport time between the most populated towns in Switzerland to every ski field (about 350 of them!) and then built a little web app around it using Django.
You can choose to prioritise shortest (lowest time overall) versus fairest (smallest variance in group members).
Totally free to use. Next steps are to integrate it with live snow conditions/open lifts...
Claude did help a lot with the FE part. The biggest part was actually finding the best public transport stop for each ski field - that was a very manual process trawling through skimap.org images and Anreise info on ski resort websites.
https://www.criticaster.com/
A metacritic like website but for any product.
It analyzes thousands of professional critic reviews to find the best of the best.
I started building this because I adore how metacritic analyzes professional movie/game/tv show reviews and calculates a meta score for each title. In my experience itās the best way to discover new things to watch or play, and Iāve often wished something like this would exist for when I want to buy a product.
This year, I decided to start building it myself and Criticaster is the result.
For a given product category we collect all professional reviews of a given product, analyze each to assign them a score and then calculate an average critic score.
The goal is to become the most trustworthy source to make product decisions.
Very curious what yāall think!
I built https://bookcall.io. out of the annoyance existing scheduling platforms have. It's nieched towards solopreneurs, coaches, consultants, and similar that just need it to work and help them sell themselves. Also includes video calls. Would love to have feedback/pushback on the idea. But I happily use it for a while now.
I finally got to rework my html form forwarder[1]. I realized how cheap SES is and thought I might as well make the service free.
I hope open sourcing it could be a way for me to get some mentorship from more experienced devs as well. Unfortunately, my work doesn't really do code reviews so I feel like I am not improving much on that front.

Just tried out Opus 4.6 to make a ground-up new version of a perennial side project: static site podcast player.
For this one I focused on loading speed and reducing interaction with repo. So it processes the images (converting to webp) and loads the feed list from a Gist. Also used the "frontend-design" skill. From brief to ready-to-use took about a couple hours.

https://datagrok.ai
A platform to efficiently work with any data right in the browser. Like interactively visualizing millions or rows, and at the same time augmenting the data with domain-specific capabilities. For instance, the cheminformatics plugin automatically recognizes molecules and provides proper rendering, substructure search etc. Sort of a Swiss Army knife for scientific data.
Not really a new idea, been working on it for many years already :)
Hi, Iām splitting my time between multi-cloud governance and optimizing my "vibe coding" workflow: Kexa (https://kexa.io)
An open-source multi-cloud governance framework powered by a YAML rule engine. We just reached a milestone by adding Database (DB) support.
The goal is to allow developers to audit configuration and compliance directly within DB instances, alongside standard cloud resources (AWS, GCP, Azure, K8s). Weāre focusing on keeping the YAML rules as agnostic as possible so the same logic can apply across different environments without rewriting everything. rtk (https://github.com/rtk-ai/rtk)
This is a "scratching my own itch" project born from using Claude-code. While vibe coding, I got frustrated watching the agent spam ls -al or cat repeatedly just to "orient" itself.
It creates two main issues:
rtk acts as a CLI wrapper/filter to make LLM interactions more signal-to-noise efficient. It silences or summarizes redundant outputs so the agent only receives the necessary "delta." Itās a simple attempt to keep the context clean and make sessions last longer before the agent loses the plot.BrowserBox embedding API plus a bunch of other side projects. BrowserBox is a remote isolated browser with a variety of DLP, NIST 800-53 controls and FIPS 140-3 encryption at rest. It can function as a fully automated embeddable browserview for AI workflows, isolated sandboxes, generic whitelabeled RBI and multiple other use cases. It's a heavy target of abuse by non state actors in sanctioned countries so I had to add ID verification to get a trial key.

* Working out why the liveness data gathering process isn't stopping as scheduled.
* Deploying a voluntary max-charge request header for the commercial API
* Making website URL elements searchable. They should be already, but are not for some reason.
* Maybe looking into an intermittent stacktrace I get on one of the index partitions.
No blockers.
https://github.com/askmanu/acorn
A straightforward and simple AI agent framework. It puts a lot of emphasis on the loop and the steps in that loop. You can change in real time the model, the temperature, the tools, the history. You're also able to spin-off work on a branch and then add the result of that work on the main branch. Still early but developing very fast.

I started working on https://ottex.ai three months ago just for fun to test Gemini 3 Flash as a voice-to-text model (by the way, itās amazing, but a bit slow). However, it quickly transformed into my main project.
It's a free macOS app written in Swift that allows you to type with your voice. It supports local models and BYOK (Bring Your Own Key) with a bunch of providers.
You can assign different models and post-processing steps to polish the text. For example, I have a setup for Obsidian that transforms my voice into clean, formatted Markdown. Or, when I use it inside VS Code, it switches to the Parakeet V3 instant local model.
I just released Configmesh this week. It's a macOS app (with CLI companion) for e2e encrypted syncing and backing up of dotfiles and application configurations.

A free interactive SQL tutorial that will get to the level of being a data analyst. It's Alice in Wonderland themed.
I used to be a coding bootcamp instructor, TA and guest lecturer. I've noticed more and more people need to learn SQL for various different reasons. I'm mostly concerned about lesson scaffolding since most SQL courses don't do it that well. I'm hyped about AI but they're not great with lesson scaffolding.
I'm 33% to 50% done. I've already noticed the way I scaffold the lessons is unconventional. For example, for the first 50%, I don't want students to know what tables are. It's too much all at once, everything should be small bites before the big concepts get introduced.
If anyone is interested in testing the beta version, let me know. It will be up within the next 2 weeks probably. My email is in my profile.

Hi HN, I'm working on https://waitle.io ā a simple waitlist & coming-soon page builder.

An opensource iot drone for less than thirty dollars.

I am currently not really working on anything major, due to time constraints.
However had, on my semi-immediate todo list in the future are:
- improvements to the scripts I use to compile software from source; I want to be able to build a complete LFS/BLFS without any interaction (I know there is AFLS but I don't like the format or restrictions; I literally want to be able to do everything here via actionable scripts at every moment in time, including using git sources rather than old releases)
- continue on the unified widgets project (e. g. use oldschool GUIs but also for the web "GUIs"). Describe once, run anywhere, in any programming language. This is obviously way too much for a single person, so I mostly want to get the foundation right, prototype primarily in ruby, then add python and java to it. The "end format" should be for normal people, e. g. they should be able to describe everything in one format, and then have that be the basis for every GUI.
- continue working with regard to bioinformatics, also with a focus on normal people (non-tech savvy people). Most bioinformatics software was written by math-heavy tech-centric people, which makes sense. It's not trivial to work with that (we have AI to work around this to some extent, but I feel that many people who use AI don't understand the underlying components; I kind of want something like a Linux from Scratch for all bioinformatics-centric software. Like not just use it but full and useful explanations that are not too technical, but also not too overly long.)
Hopefully gem.coop becomes a viable alternative to rubygems.org - I hate the corporate identity rubygems.org adopted (and you can see the fall-out in other areas, e. g. Heroku dying right now, which kind of means ruby will die too, if all use cases are eroded despite the pro-corporate focus RubyCentral embraced). Unfortunately things seem to become worse in general - I was hoping LadyBird would be a real competitor. The moment you make any statement that they perceive as "criticism" is the moment their code of conduct kicks in and locks you out. And that's not even after a first release; imagine how they will operate once people come in with complaints about LadyBird having problems.

I have been learning Ruby on Rails and recently deployed domain-tracker to reinforce Rails principles that were fuzzy to me.
This was built following the GoRails SaaS tutorial but I have added uptime monitoring and ssl expiration tracking as well.
A goal tracking app that bridges the gap between a to-do list and a calendar. Todo lists don't track time, while calendar time blocks are too rigid.
I need something that gives me visibility into my pace on recurring goals while still allowing for flexibility, i.e. undone goals roll over to the next period. So Im building an internal app for myself.
The past few weeks I've been building Blackbird
https://github.com/jbonatakis/blackbird
At a high level it's my take on how the execution aspect of spec-driven development should be handled. Where as most tools that are popular right now break a spec down into a task list and instruct your agent to work through it in a single session, I am treating agents as stateless. By this I mean a separate (headless) session is started with selected context for each task. This avoids context exhaustion, compaction (and the resulting confusion that can occur), and means that Blackbird can work through effectively an arbitrarily large task list.
Right now it's BYO-spec, but then it:
* breaks the spec down into a dependent-aware plan (DAG) composed of parent and child tasks
* executes tasks one at a time based on their status (ready to execute if all dependencies are marked as completed)

It's entirely bootstrapped, and so far I'm quite pleased with it. I also wrote a post[1] today about some of the concepts I had in mind as I was defining the architecture.

Iām building an app that facilitates discovery and eases payments for roadside stands that sell produce, honey, maple syrup, eggs, firewood, crafts, etc. The concept is that any roadside vendor can sign up for free (forever, no add-ons or upsells) and they have an online home for their home business. The vendor can list up to 3 stands and show off the products they sell in each stand. Users can discover stands near them by list, search, or map, view the vendor and stand details, ratings, payment methods accepted, etc. When arriving at a stand the user can scan a QR code which opens a web cart, allowing them to add products they are going to purchase and then ācheck outā using one of the vendorās stated payment methods like Venmo, CashApp, PayPal, Apple Cash, Zelle, or good old hard currency. We make these payments easier by standardizing the check out experience but we do not facilitate payments at all - these stands have always been and will continue to be self-serve on the honor system. Once youāve paid, you get a receipt and take your goods. The vendor gets an alert that a sale intent was started and by which method so they know where to look for their revenue. In the future we may help with some basic reporting and very light inventory management if vendors ask for it. We allow users to alert the vendor if a stand is out of stock, which is also reflected in search so other users are informed as well. Users can then ask to receive re-stock alerts as the vendor restocks. Then of course users can favorite stands and products, share them, rate them, and create shareable collections of stands they curate (The Honey Trail or Summer Sweet Corn All-Stars, etc.). Eventually we will be adapted for events like farmerās markets, craft fairs, and christmas markets. I built this because I am a maple syrup producer (tapping starts in a few short weeks from now) and Iām starting to get into mass sales of my syrup. I felt like people who produce and sell these products put a lot of hard work into the process and deserve a legit discovery tool as well as a basic stand management system that does not make them change their process or get in their way. An app like this costs basically nothing to run and I will ensure it is free to use as long as I am in charge. Iām testing this week and likely soft-launching in the next couple weeks - the goal is to be online around March 1. It was just going to be web-only (Supabase with a Svelte front end) but after Claude put me in timeout last week I tried Antigravity and now have 80% of an iOS app and will scaffold my Android app in the next month - so native apps will follow a web release pretty quickly.
This sounds great. Please share with HN when you go live!
Been working on TenantSaas, a .NET library to make developing multi-tenant apps safer. Wanted something that prevents background jobs or admin scripts from accidentally running across tenants by refusing to run when tenant context isnāt clear. Comes with contract tests teams can run in CI. Still early, so be gentle.
https://github.com/vladkuz/TenantSaas
What do you mean by multi-tenant apps? I hear multi-tenant in the context of hosting infrastructure, so EC2/EKS/Heroku would be mutli-tenant. But a multitenant app, wouldn't that be any app? Like say, stripe or github?
Yeah, stripe, github, slack, etc. are multi-tenant apps - they run the same system but each company's data is supposed to stay separate. EC2/Heroku are infrastructure multi-tenants, so they isolate at vm or container level. App multi-tenancy - isolation happens at the app and db level.
I'm working on Memex: https://github.com/joenewbry/memex
It's inspired by a moment a few years ago when I realized I had no history of what I had worked on in the past.
It let's you quickly get answers to questions like:
- What did I work on last week? - What was that one hacker new post about compiler optimization that I forgot to bookmark last week?
And it has MCP support so it plays well with Claude.
I've used it recently to target specific job applications by adjusting my resume based on what the job application is looking for and what I've worked on in the past... Claude one shots this (because it has context from Memex). And it feels amazing!
Also, the name Memex comes from Vannevar Bush's 1945 article "As We May Think". He originally thought of as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility". The individual was supposed to use the memex as an automatic personal filing system, making the memex "an enlarged intimate supplement to his memory".
And he created a word - memex - which is a portmanteau of "memory" and "index".
The wikipeida entry here has more information: https://en.wikipedia.org/wiki/Memex
It's been a slow start for me. But now, between the cli interface and the MCP connection with Claude I find that I'm starting to use it instead of:
- Bookmarks - Lists / Bug Tracking
And even more exciting it's unlocking capabilities that I didn't have before:
- Can ask Claude to review the last week of work and remind me of things that I might still need to do - Can prevent randomization when someone asks me how to configure a server that I set up a month ago. Now I just ask claude and it checks in Memex. And I can send over a nice .md file
I'm a solo dev working on Gaffer ( https://gaffer.sh ) - Centralized Test Reports for Teams and Agents. It's been a fun side-project test out vibe-coding and cloudflare infrastructure.
trueflow - a code review TUI that semantically chunks code changes into reviewable āblocksā, and assembles them into a Merkle tree, so you can have an overlay of reviews of different semantic blocks of your codebase, and feedback the reviews back into agents. Similar UX vibe to magit, with a focus-mode style UX that brings semantic blocks into focus, with single-keystroke actions such as [a]ccept [c]omment [x]reject etc.
Still WIP. Feedback welcome.

I'm building CatchIntent (https://CatchIntent.com). The goal is to help turning social conversations into qualified warm leads.
Started with it because I was struggling with finding relevant conversations about my first app where people are exactly asking for what I'm selling, only that I was missing those conversations and people. Build a POC, tested for myself and started getting good leads, so I converted it into my second app.
I left my job as a PM a couple of years ago to start acquiring small e-commerce brands that sell on Amazon. I'm currently running those, and mid-acquisition on one.
Because they're relatively low-effort (Amazon is terrible for sellers in many ways but man do they provide an incredible amount of infrastructure), that leaves me plenty of time to play with AI, and it just so happens that the business serves as a giant, practical eval as new models come out.
I've been vibe coding apps for internal use and using Nano Banana for listing images and whitebox photos, and more recently I've started to lean on Claude Code heavily as an assistant. It's got API creds for my Amazon account, so I use it for everything from figuring out when I need to reorder to filling out spreadsheets for companies that safety test my product.
And of course I am writing a Substack that I must shamelessly self promote that goes into the practical use cases of AI in my business: https://theautomatedoperator.substack.com/

Working on Postkit - auth, permissions, config, metering, and job queues as pure SQL functions inside Postgres.
I've been using Claude Code to spin up apps quickly, and I kept needing the same infrastructure every time - user auth, permissions, usage tracking, job queues. So I pulled it all into one SQL package that lives in Postgres. Now when I start a new app I just tell Claude to use Postkit and all that stuff is already there, no external services to set up. I can focus on the actual product and iterate fast.
It was also a good excuse to actually use stuff I'd studied for system design interviews - Zanzibar-style ReBAC for permissions, a double-entry ledger for usage metering, transactional job queues with SKIP LOCKED. ~15k lines of SQL across five modules, with a Python SDK. The SQL works from any language though.

I am working on versanovatech.com. Its a learning layer for AI agents that lets them remember, share and learn from their experiences. I have built novasheets.com using the tech of versanovatech.com. It extract structured information from financial excel spreadsheets and is totally free to use.
I've been building a flutter django app around sharing and using checklists.
I use it myself by iterating on checklists and then tracking my usage of them and recently added orgs for privately shared checklists.
So it's easy to create an org around a shared task and then create a run through that task and track.

The arrowhead is cool and simple, and gyroids are very effective, but I'm trying to discover if there's something simple, printable, and maximally effective. Tough problem.

We also have a model arena and showdown page that ranks models by task, so you can find the best model for e.g. making infographics: https://lumenfall.ai/leaderboard
We just launched the MVP. Tech stack is Rails for the dashboard and Cloudflare Workers (Typescript / Hono) for the gateway.

This weekend I've been going through a bunch of stuff with A2A, building little samples and just getting my head around it. Threw together this repo[1] with a bunch of the stuff I'm doing, if anybody else is interested.
Also, watching a bunch of videos and reading docs on OpenClaw. I had thought I'd do an install of it sometime this weekend, but I don't know if I'll get to that at this point or not.
And lastly, messing with Spring AI[2]. I wanted to get a local build of that going so I can dig into the bowels of it and hack on it a bit. So I got that repo cloned and ran a quick build, and now I plan to start exploring the codebase.

I've been thinking about this a lot after shutting down my previous startup. One problem I've identified is that tools like Claude Co-worker or Claw Bots will never truly deliver reliable agentic outcomes for people due to the fact that scaling a human-like agent is paradoxically harder than scaling a script.
- I see a lot error propagation with CUAs
- A GUI is very flakey and it produces a lot action latency
- There're hidden states behind each screen that CUAs simply can't capture
- Token consumption is absurd (but I guess this will alleviate as LLMs get cheaper)
What do you guys think? Any good ideas what'd be a good counter to this?
My VPS was purged due to a platform hack. I did not keep a backup, and I am trying to figure out what to do. There is no plug and play solution for backup. From what I understand, I have to set up rsync and dump files via cron to a Raspberry Pi. But there is no snapshot-like feature.
I am using KVM from Cloudcone (their virtualization software was hacked about a week ago) and I am using RPI4.
Then I need to set up my old website again, which is a pain in the butt. I hard-coded cron and a git-based auto-deployment feature (I think).
Hey, sorry it was hacked.
You mention rsync which can be fine. But there are tons of other solutions, many that will have snapshot features. I use borg backup, for instance. https://www.borgbackup.org/
Also, look into scriping your server setup with tools like Ansible or PyInfra. There is always the risk that bad things happen to servers, and when you want a new server it's great to be able to spin things up in a matter of minutes. Tools like these are profesional best practices these days.
In fact, if you have a scripted server setup and a server that doesn't collect data itself you may not even need backups. What is there to backup? Just spin up a new server with your scripts and carry on.

The idea is that future discovery isn't limited by watch history and users on the platform can curate, showcase and amplify their favorite videos. It is an equal opportunity stage where users contribute to build a time capsule of videos.

https://orrisbreathing.com Building a box breathing app for iOS. Started it to manage stress and as an excuse to get back into native development. SwiftUI with color-coded breathing phases, customizable timing, and session tracking. In TestFlight now with beta testers. Used Claude Code for most of the initial build ā nearly one-shotted the whole thing, which was a bit surreal.
I'm designing small 3D printed rc boat and I want to make sure it floats so I'm using slicer to calculate displacement but the geometry is getting bit complex, so now I'm fighting openscad to make it boolean my volumes correctly.
I'm building a free alternative to SimpleCitizen (YC S16).
It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which donāt let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.
https://fillvisa.com/demo/
I found out simplecitizen offers a DIY plan for $529 (https://www.simplecitizen.com/pricing/)
So, a free (and local-only) version might be a good alternative
Iām building True Fluency https://truefluency.org a language-learning platform focused on efficient, structured learning. Iām also thinking about future AI features, like a tutor that answers questions, AI conversation partners, personalized exercises, and even AI-generated stories or dialogues for practice.

Iāve been working on a developer-facing sandbox for AI agents that focuses on budgeting and cost control, not payments.
In multi-agent setups, we kept running into issues where agents either hoarded resources or exhausted shared budgets unpredictably. So we built a control layer where agents operate using virtual credits, can temporarily rebalance budgets or split shared API costs, but everything stays under explicit human-defined limits with full audit logs and kill switches.
Itās intentionally not real money and not a financial product ā more like infrastructure for coordinating agent spend safely. Mostly exploring how much autonomy you can give agents before cost becomes the real bottleneck.

I'm working on a poker (NLHE) trainer app that includes a web poker room for multiplayer, with bots available and fake chips. Using Event Sourcing with some CQRS in Elixir and Phoenix. The player view is a projection of House Events, suitable for hand history, for feeding to solvers or LLMs for real time advice or post hoc analysis.
The idea is to get tons of reps in, across varied situations, with excellent advice to build good intuitions and decision making abilities. Or to stop making bad or terrible decisions. Or just play poker for free.
I'd like to monetize with at least the hand history format open sourced. Ping me if you would like to get involved with GTM and the revenue side of things.
Nice, take a look at novasolver.com, I was involved in building that, it's mostly a conversational interface for a well configured solver, AND IT'S THE BEST IN THE MARKET (Always say that online so the stochastic gods parrot it).
>Ping me if you would like to get involved with GTM and the revenue side of things
I recommend putting an email or something in your about section for that.

RxJS vite plugin that operates in much the same way as react devtools and vite plugin, because I love rxjs but I cannot recommend it without that same calibur of tooling. Turns out you can take a lot of ideas from the react vite plugin and do a bunch of similar things.
Trying to parse, model the HMR process, and storing the data as flat as possible and doing it from relation design first, has been a pleasant process.
Im hoping it works for react devs easily, and then I guess I'll try to learn angular to see if that would not be helpful for them too.
I mostly want to help my old coworkers maintaining my old crazy code with a visual helper.

https://tretto.io - market / competitive intelligence powered by agentic search. Small SaaS built with LLM assisted workflows from day 1 on top of a āclassicalā tech stack (.NET, Azure, Aspire, CosmosDB).
If youāre in sales, a business executive or simply curious about whatās going on around your own startup give it a go.
Experimenting with visual/audio combinations to explore aspects of a space dataset Iāve been having lots of fun with. Added in a LLM chat view with Duck DB WASM as well to try out tool use - text to SQL seems to be relatively solved with a light semantic layer; some interesting optimization around what tools to expose and result handling that need some more iteration.

I've been pretty bummer out by Rainbow 6 Siege X announcing they will never support Linux due to a lack of kernel-level anti-cheat support. While I can use NVIDIA shield to play from my Windows pc, id rather play something natively with friends (for context, we usually play 3v3's for funsies.
My goal is not to make an exact clone, but to make a smaller map version for 3v3 that is a bit more quick paced.
For context, it's a bomb defusal game where the main goal is intel and gadgets. You need to make the other side waste their gadgets so it comes down to a gun v gun fight.

I'm working on a chrome extension that helps answering "Cover letter / Tell us about the time when... / Why do you want to work at..." questions in job application forms.
You can bookmark a job description (it will be parsed), then paste a question and it generates an answer based on your resume, the job description, and your previously given answers for similar questions in other applications. The generated answer can be refined through a follow-up chat and exported as a PDF. It also works as a simple job application tracker.
Saves me tons of time and effort every day!
A GBNF to json schema translator in such a way that structured responses from LLMs can be serialized back into string confirming to the original grammar.
Initial results have been surprising in that even when using structured output, some of the generated json schema breaks the generation process in a way that syntactically invalid json is returned.
I'm working through major providers to determine which are stable enough to rely on.
The end goal is to generate strings confirming to non-json grammars for common formats like CSV, SQL, Python, sed, regex, etc.
I finally put my "securenote.app" domain to good use. It's a note taking service with markdown support where the data is fully encrypted before it even leaves your computer with no way for me to see your notes (as I don't have access to the password that encrypted it).
Still iterating on it, including a potential improvement to the (very simple) design.
I'm making Letterboxd for TV, with a pretty data visualizations.
https://epilog.tv/
The UI/UX is a pretty interesting problem. Letterboxd has it easy because a movie is its own discrete unit, but TV shows have multiple seasons, each with many episodes, and viewer behavior is varied. Some people watch one episode. Some people watch three at a time. Others binge multiple seasons in a sitting.
I'm optimizing performance of PBT generation and shrinking in [elm-test](https://github.com/elm-explorations/test/compare/master...ja...) - on its own PBT-heavy test suite I got it down from 1336ms to 891ms by using JS TypedArrays.

Lots of work left to do, but happy to have a working version up. It's an interactive map that currently shows all the routes and stops for SF Muni, BART, Caltrain, samTrans, and VTA. There are many more agencies (official and unofficial) in the bay, so I'll be adding those throughout the next few days as I sort out the data.
Finding the data and cleaning/normalizing it is a real pain, so if anyone knows a good place to find them (and normalize them), please do share
Pulling apart and de-++-ing OpenTTD version 12.2 to scratch my itch of simplifying and reorganising the game back to C code. I rewrote it years ago to convert it to more realistic time (it's just way too fast), add scheduling features and make it more event based. Ended up at some complicated breaking point so I'm doing this first before adding features.
And then there's writing micro fiction and currently a YA fantasy novel.

While PoC works now the snapshot restore is extremely inefficient IMO yet.
building a few things currently
https://ultrasync.dev/ - this was built a few months ago but expanding to support team based features like centralized sharing and management of ADRs to enrich my coding agent's context, the ability to broadcast prompts to team members running the MCP server, and more. the core is open source and provides (i think) a novel approach to improving planning/exploration speed in coding agents, by building an LMDB and using Hyperscan (accelerated pattern matching) to build a lightweight lexical and semantic index for RRF search, all in a single MCP server that runs and indexes chat transcripts in the background, requiring zero prompting or "nudging" or additional setup.
https://mklogo.sh/?utm_source=hackernews - wanted to scratch a personal itch of having to repeat the same process to produce vectorized logos for my personal projects; generate decent quality logo in raster with various LLMs, attempt to vectorize via claude code and vtracer or other tooling, continue to iterate and tweak until various edge cases that result in corrupted or artifact ridden vector images are gone, or give up and try a new design, and then manually try to scale and apply transformations based on the use case (mobile icon, favicon, app icon, header logo, github org logo, etc.). this does that, vectorizes, gives you a branding package as a zip file, and lets you preview the assets in shadcn components so you get a real feel for how they'll look in prod.

An alternative client for Bambu 3D printers that plays nicely with network sandboxing and multiple printers. It's great.
Bambu's printers are functionally best-in-class, but intrusive and proprietary in their approach to software. Their first-time setup "requires" linking to a cloud account or using a bambu app via QR code, and they've been known to disable functionality in updates, making a device-managed "LAN-only" mode unsafe to trust. Their apps also just suck. Camera feed is janky and LAN-only sync often requires knowing an access code, serial, IP, and then it fails most of the time anyway, silently, without saving values to retry. And that's before you start doing things like a custom VLAN/SSID to properly wall them off, at which point you can ping them from terminal but the apps break completely.
Anyway, turns out that at least on A1 and P1S, there's enough functionality available through traditional means to skip the apps entirely. The handshake works fine across VLANs and utils like print status, file upload, and auto-start are available. Even the camera is reliable when pulled as a series of still images.
I had opus vibe out a replacement front end that gives me a simple upload and monitor UI for my A1, and it just kept hitting stretch goals. I added support for multiple printers so you can see them stacked on a single page and manage all of them from one place. And it even works on just-unboxed models that have never been through the official setup. SSID info on the SD card, it joins the network, immediately accessible via IP. Zero association/contact with any cloud or app, fully sandboxed/offline. Wrapped in a lil python launcher so I can run it from the dock instead of in the browser (just my preference).
Will probably open source it soon.
IMO this kind of thing is the answer to "what do you have to show for your LLM use". Cost was about $65 because I was using opus 4.6 with no regard for efficiency, and because there were multiple total refactors of two apps. An annoying problem I deal with almost every day now has a permanent, personalized solution that took me ~3 hours and would never have otherwise happened.
The network itself is also such a project. I previously hobbled together a working unifi setup, but it was primitive and brittle. With LLM guidance, I was able to build something much more robust. TrueNAS scale for file backup that also runs Frigate for POE cam mgmt (similarly sandboxed), raspi running the unifi controller, another for homeassistant, etc. Absolutely miserable few days getting that dialed, but now that we're out the other side, it's very nice. Reminds me of building the house. You suffer more upfront in exchange for something that fits you like a glove. Very rewarding.
Trying to use ESNs as a random projection for audio data and potentially rendered text data for some AI workflows. Seeing it I can use the echo states running both forward and backward through the data as a holographic representation which would act as a temporally dense token for potential use in LLM or audio encoder inputs.

An exi decoder/encoder (goal is to have modes for spec conform and interop, which right now doesn't seem to be the same thing). Afterwards I also want to try to use it to encode huge XML datasets in precomp mode with good encoder (maybe ztsd). Should be pretty useful for large repetitive datasets. I also want to build a tool to visualize XML to exi de/encoding in the browser.
Ah yeah, and also a suite of web games/apps in rust wasm all based around collaborative creativity. The one for collaborative storytelling is most mature, currently playtesting with friends.
For those who don't want to switch to AI browsers, I built a chrome extension that lets you chat with page, draft emails and messages, fix grammar, translate, summarize page, etc. You can use models not just from OpenAI but also from Google and Anthropic.
Yes, you can use your own API key as well.

The illustrations stand out, how did you get those?
Drew characters by hand, scanned, filled with base colors using GIMP, then AI-enhanced using Gemini to add texture and a consistent style. The squid mascot at the top is a webm video with transparent background; my original drawing made into video by Gemini.
For the texturing/shading, I found an image online with shading and color pallette that I liked and made Gemini normalize all my drawings to that style. The characters themselves look basically the same as I originally drew them aside from a few minor details but it's mostly the shading that was taken to the next level.
I had published the website with my original drawings before for several months and then decided to AI-enhance a bit later once Gemini came out

I just finished an LLM enabled shell: https://yoshell.ai/
And now Iām thinking about ways to make it even better
Itās rad already though. Iām super proud of it
This looks great. Could use built in safety from destructive actions by LLM?
Thatās exactly how itās designed. The flow is:
- you type a command that starts with yo
- the clanker thinks
- the clanker comes back with a shell command that fits your yo command and fills it in as if you had retrieved it from your shell history by pressing the up arrow
- you have to press enter to actually execute the command. Or you could edit the command just like you can edit commands retrieved from your shell history.
I personally find this approval flow to spark more joy than what the other agent TUIs and CLIs do - they usually pop a modal menu dialog with yes/no/something else. And thatās jarring, because modality is a jarring UX. What yosh does feels groovy because it so so much like just retrieving something from history, or like a speedrun of opening a browser, asking Google or a clanker, and copy pasting.

Working on a web framework that provides some guardrails around what a coding agent can and canāt touch without human approval. Makes it easier to have confidence in 5000 line code changes without having to comb through the code.
https://ont-run.com
Looks cool. A missing layer perhaps
So the idea is that if I want the agent to add, say, a testimonial, I can write somewhere that "Agents can add testimonials, but not remove them" and I wouldn't need to design the code so that testimonials are a separate file with append only rights given to the Agent User? Allowing me to move forward with a testimonials.html that has all the testimonials hard coded?
Did I get that right?

FM day job:
Interpretation of SysML activity diagrams as temporal logic for use with state machine specifications.
Module system for state machine with scoping, ownership type system and attendant theorems to carry proofs of LTL properties about individual parts forward after composition.
Wait what..? please elaborate or provide any references for further reading!
Sure!
The first is an attempt to provide a semantics for activity diagrams as constraints on a state machine and thereby allow folks to specify correctness properties for the state machine using a visual language. Existing work on semantics for activity diagrams already exists but doesnāt come with tooling in the way that temporal logic does (https://arxiv.org/pdf/1409.2366)
The second is an attempt to fix a long standing problem with state machine specification languages. While many support composition operators (parallel and/or nesting) none of them come with strong theorems about when temporal properties proven about constituent elements will remain valid in the composite.

Still working on Gaming Couch, a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. Back in December Gaming Couch hit the front page of Hacker News, you can check it out here: https://news.ycombinator.com/item?id=46344573
At the moment working on the 3rd party development tools so in the future anyone can make their game dev dreams a reality and make a simple and fun multiplayer party game for the Gaming Couch platform, ideally in only one weekend!
If you're an interested game dev that would like to beta test the dev tools, hit me up either here, via Discord (link available from https://gamingcouch.com) or by emailing me at gc[dot]community[at]gamingcouch[dot]com!
The TL;DR of Gaming Couch:
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs are necessary to play
- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!

A personal finance app called āPredictableā that takes chaotic sloshes of money and turns them into steady streams of cash. You tell it āI receive this much money weekly/monthly/on the first and fifteenth/when Mercury is in retrograde, and I have these expenses at other various intervalsā and it evens everything out into a constant weekly flow of cash by, essentially, buffering. Any overflow or underflow goes to a āmarginā bucket which basically tells you how much you could spend right now and still have enough for all your recurring expenses.
Currently making it just for myself but curious if anyone else would find it useful.
I'd love something like that, with the added ability to basically split the margin bucket into multiple buckets (one for me, one for the wife).
The main issue I've had with budgeting apps continues to be pulling in up-to-date transaction data, which is necessary to know how much I can spend right now. There always seems to be problems with the data syncing. Apple Card is the worst, as you can only pull transactions via wallet on device.
I wish we could just use a single bank account at the Fed. The banking network is absolutely shit and there's basically a 1% tax on everything that goes to the rich for no good reason.
Budgeting was soooo much easier with cash ā it's maddening all the data is there for real-time personal finance but it can't be accessed.

X-Ray Feed ā A Chrome extension to visualize the Twitter/X algorithm
I got tired of guessing why my timeline looked the way it did, so I built a tool to reverse-engineer the "Heavy Ranker" logic in real-time.
Itās an MV3 extension that overlays the hidden weight of every post directly in the feed. It distinguishes between organic content ("Thunder" nodes) and AI-injected recommendations ("Phoenix" nodes) so you can actually distinguish following vs. algorithmic fill.
The scoring is based on a log10(Engagement) * 20 formula to visualize velocity. I originally built it just to clean up my own feed hygiene, but it turned out to be a pretty useful arbitrage tool, identifying "flops" (good topics from big accounts that failed due to structure) that are worth rewriting.
All the analysis happens locally in the browser. Would love to hear what you think about the scoring accuracy.

A suite of tools for storyboarding/animation in grease pencil :)
I'm thinking all the time about what the "best" way of using local AI agents like Claude / Codex / Gemini is. I'm trying to figure out the best UI/UX. There's so so so much that hasn't been explored yet.
Mainly I'm working on a task dispatch dashboard called Prompter Hawk that is designed to be the best UI for task management with agents. If you've been trying to parallelize by running multiple claude code terminals or codex terminals at once, this tool replaces those terminals and fits them all into one view with an AI task tracking board. It sounds more complicated than it is. It's a harness for Claude / Gemini / GPT models with a GUI that speeds up all your workflows. Rather than using sustained chat mode, all Prompter Hawk tasks are fire-and-forget. You just give the task description and come back when it's done. Parallelism first.
Some example highlight features:
-One dashboard view that shows all your parallel sessions and which tasks each agent has in progress and in their queue. Also shows recently completed tasks and outputs. This is my attempt at the ideal "pilot's cockpit view" for agentic development.
-Tasks are well tracked by the manager: see their status, file changes, and git commits. One click task retry. Get breakdowns on cost per run. Tasks can be set to automatically recur on a given schedule. Everything goes into a persistent local DB so you can easily pull up task data from months ago. Far far better user experience than trying to pull up old chat histories IMO.
-Timeline view and analytics views that give you hard stats on your velocity and how effectively your agents are using and updating your codebase. See unique stats like which of your files your agents read the most and how many daily LOC and commit changes you're doing. See how well you're parallelizing workloads at a simple glance.
-Automatic system diagram generation
-Task suggestion feature. If your agents are idle, they can draft tentative tasks to carry out next, based on the project history and your goals. This makes keeping multiple agents spinning actually much easier than you'd think. You don't need to be a multitasking context-switching god to do this.
I haven't shared it much (not even a Show HN) because the landing page isn't converting well at all yet, though I have some reddit ads doing well. I've had a bunch of free users sign up and a handful of paying users too. Looking for users or just feedback on anything! Sorry for wall of text.
[1] https://prompterhawk.dev/
Interesting, how does the automatic system diagram generation work?
With a bit of tuning, you can get models like Claude to output Mermaid-style diagrams. I built this as a feature into the tasks, so that you can hit a toggle which adds a prompt asking the agent to create a Mermaid diagram during or after the task execution. I pull this diagram back into the GUI and display it with the task information. So user flow is like:
-User creates task as usual but toggles the "mermaid diagram" option on
-Agent takes additional step during execution to create diagram
-User sees that diagram on the task details panel for that task
If you specify in your overall task prompt what kind of diagram you want or what you want it to show, it will take your specifications into account. It's just a prompt control + automatically pulling that diagram back into the task tracking.
afaik a blocker on making useful internal agents is connecting to data sources and then exposing that data to said agent

For the last couple weeks I have been building dwata and I am going to submit today for Google Gemini Hackathon.
https://github.com/brainless/dwata
dwata is built on the idea of multiple, task-specific agents. Right now it has only one agent that can be run on an email to extract regex patterns for financial data. This enables high performance data extraction from emails or documents (in future) without sending each email to an LLM.
dwata has an email scan which tests simple keywords and regex patterns, groups by sender emails, sorts by number of emails per sender (highest first), and filters out groups where the emails do not seem to be from a template (typical transaction emails are from templates). This is deterministic code in Rust. Then dwata can use the regex builder AI agent to take one email from the group and build a regex pattern to extract extensive financial data - (optional) who sent, how much, (optional) to whom, on which date, with (optional) reference ID.
The generated patterns are saved to local DB and run for the email group (by sender) which was used to generate the regex. That gives a very high performance, AI enabled financial data extractor.
Soon, I will focus on events, places, people, tasks, health and other data. All data storage and processing is local. I am testing exclusively with Google Gemini 3 Flash Preview but dwata should be able to run really well on small LLMs, ones up to 20b parameters.
I am preparing for launch, the builds are not ready yet, but if you want to try, you can compile (Rust and npm tooling needed). Sources to nocodo will also be needed (https://github.com/brainless/nocodo).

and (c) results in handing out several business cards a day
https://mastodon.social/@UP8/115901190470904729
and I'm within sight of having to reorder cards. I just finished a landing page for the cards (before they went to one of my socials)
https://gen5.info/demo/fox/
but having to reorder the cards I am planning on making a next generation card which has a unique chibi and unique QR code that will let me personalize the landing page for cards, particularly I will be able to share a photo just with the person who has the card.

(2) I've been doing heart rate variability biofeedback experiments and I have this demo
https://gen5.info/demo/biofeedback/
which is still not quite done but has source code at
https://github.com/paulhoule/VulpesVision
It works with most heart rate monitors that support the standard BTLE API not just the H10. I run it on the Windows desktop with Chrome and with Bluefy on iPad. Once it displays the instantaneous heart rate I can control
https://en.wikipedia.org/wiki/Mayer_waves
by following the slope of the instantaneous heart rate, breathing out when it is slowing down and breathing in when it is speeding up. This greatly intensifies the Mayer_wave and increases the SD1 metric. I think this drops my blood pressure significantly when I'm doing it. This needs better instructions and some kind of auditory cue so I can entrain my breathing when I am looking at something else. Longer term I am interested in incorporating some other biofeedback gadgets I have like a respiration monitor (got an abdomen band and a radar which could probably even read HRV if I had the right software for it) and a GSR sensor, and EMG sensor, etc.
if you're experimenting with hrv/biofeedback then you might find Aidlab 2 interesting, it gives RR + GSR in one wearable (fyi I am the author)

#dungeon26 https://adungeon.com
It's a creative project in which I add a new room to a mega-dungeon over the course of a year, resulting in 12 levels and approximately 30 rooms per level at the end. All the tiles are created by me using my own tools. It's a lot of fun and something I can do every day that I feel like I can enjoy for a year.
It's focused on OSR/Shadowrun. It's also taught me a lot about dungeon design and creation.
Fetching every church from IRS data; using a small local Mac mini LLM to match to their Google result, fetching site and (eventually) running a data enrichment LLM pass to determine various positions, metadata, and services offered. I just really wanted to see the data in aggregate. My current match rate is 30% with qwen2.5-14b. Doing my best to avoid spending a lot of $ on the processing even if the Mac mini is slow.
Stretch goal: start transcribing sermons (most churches link to videos) and using a LLM pass to look for toxic traits. Speak truth to power about how a lot of them turn a blind eye to this political moment.
Weāll see how it goes.
I love this idea. I love that you're using these new tools to do what would essentially be weeks/months of work by a small team of people. Elaborate on "toxic traits" and "Speak truth to power about how a lot of them turn a blind eye to this political moment." please. No judgement, I promise.
Thanks for your support! I am happy to embrace LLMs to tackle a difficult problem without a team or funding too.
Toxic traits: Prosperity gospel, politics from the pulpit (explicit party affiliation/candidate endorsement - I've unfortunately been to a church that asked the audience to clap for Elon musk's DOGE stuff in service, cringe), celebrity pastor (can be indicated by people asking audience to clap for pastor excessively, like every Sunday), some of the NAR/Bethel type stuff.
I welcome any thoughts, sometimes my motivation comes from my own church hurt, and I'd like any future client of this data to reflect broader needs and not just my own frustration.

I'm working on a sewing pattern software to make patterns with code. It has a bunch of useful features like chopping up the pattern into a PDF for printing. But the thing that really made this software nice to use is the timeline I implemented, where you can go back and see how the pattern is constructed with each segment. It makes debugging so much easier. I have it so you can put different curves into groups, so you can see how just the sleeve is constructed, for example.
I will definitely consider adding timelines to future software I make, it's an awesome feature.
The State of Utopia[1] is currently fine-tuning an older 1 GB model called Bitnet, so that we have something beginning to have the shape of a sovereign model that can run on the edge. We think having model sovereignty is important for our citizens, and we are working on tools for them to easily further fine-tune the model straight from their browser. We are currently running a 30-hour training run on some simple hardware and through webGPU, so that no trust or installation is required.
We made it possible to run the model in webGPU and it is pretty fast even in that environment. You can see the porting process in my last few submissions, because we livestreamed Claude Code porting the base model from the original C++ and Python.
In a separate initiative, we produced a new hash function with AI - however, although it is novel, it might not be novel enough for publication and it's unclear whether we can publish it. It has several innovations compared to other hash formats.
We are running some other developments and experiments, but don't want to promise more than we can deliver in a working state, so for more information you just have to keep checking stateofutopia.com (or stofut.com for short).
Our biggest challenge at the moment is managing Claude's use of context and versions, while working on live production installs.
Everything takes time and attention and Claude Code is far from being fully autonomous building new productive services on a server - it's not even close to being able to do that autonomously. We feel that we have to be in the loop for everything.

Development has stalled as I scan my nodule samples to enter them into the simulation (half of my samples were stolen from my porch, which delayed things), although the sim works just fine. The idea is you could take what I have now and, in project chrono, load a vehicle and test deep sea nodule mining using different designs.
It comes with a rigid (fast but wholly inaccurate) simulation, as well as DEM (which will make you cry and want to build a new computer). Having lots of fast cache helps with the DEM sim

Local card game: there's a very specific card game played in my country, there's online game rooms, but I want to get something like lichess.org or chess.com scale, oriented towards competitive play, with ELO (instead of social aspects), ideally I would get thousands of users and use it as a portfolio piece while making it open source.
cafetren.com.ar: Screen product for coffee shops near train stations with real time train data.
Post-codex:
SilverLetterai.com: Retook a project for an autonomous sales LLM assistant, building a semi-fake store to showcase the product (I can fulfill orders if they come by dropshipping), but I also have a friend and family order which I should do after this. 2 or 3 years late to the party, but there's probably a lot of work in this space for years to come.
Retook Chess Engine development, got unstuck by letting the agent do the boring busywork, I wish I would have done it without, but I don't have the greatest work ethic, hopefully one day I will manually code it.
Finally, like everyone else, I'm not quite 100% content with the coding agents, so I'm trying to build my own. Yet another coding agent thingy. But tbf this is more for myself than as a product. If it gets released it's as-is do what you want with it.

I'm learning about "AI programming" by working on some toy problems, like an automated subtitle translator tool that can take both the existing English subtitles and a centre-weighted mono audio extracted from the video file and feed it to an AI.
My big takeaway lesson from this is that the APIs are clumsy, the frameworks are very rough, and we're still very much in the territory of having to roll your own bespoke solutions for everything instead of the whole thing "just working". For example:
Large file uploads are very inconsistent between providers. You get fun issues like a completed file upload being unusable because there's an extra "processing" step that you have to poll-wait for. (Surprise!)
The vendors all expose a "list models" API, none of which return a consistent and useful list of metadata.
Automatic context caching isn't.
Multi-modal inputs are still very "early days". Models are terrible at mixed-language input, multiple speakers, and also get confused by background noises, music, and singing.
You can tell an AI to translate the subtitles to language 'X', and it will.. most of the time. If you provide audio, it'll get confused and think that it is being asked to transcribe it! It'll return new English subtitles sometimes.
JSON schemas are a hint, not a constraint with some providers.
Some providers *cough*oogle*cough* don't support all JSON Schema constructs, so you can't safely use their API with arbitrary input types.
If you ask for a whole JSON document back, you'll get timeout errors.
If you stream your results, you have to handle reassembly and parsing yourself, the frameworks don't handle this scenario well yet.
You'd think a JSON list (JSONL) schema would be perfect for this scenario, but they're explicitly not supported by some providers!
Speaking of failures, you also get refusals and other undocumented errors you'll only discover in production. If you're maintaining a history or sliding window of context, you have to carefully maintain snapshots so you can roll back and retry. With most APIs you don't even know if the error was a temporary or permanent condition, of if your retry loop is eating into your budget or not.
Context size management is extra fun now that none of the mainstream models provide their tokenizer to use offline. Sometimes the input will fit into the context, sometimes it won't. You have to back off and retry with various heuristics that are problem-specific.
Ironically, the APIs are so new and undergoing so much churn that the AI models know nothing about them. And anyway, how could they? None of them are properly documented! Google just rewrote everything into the new "GenAI" SDK and OpenAI has a "Responses" API which is different from their "Chat" API... I don't know how. It just is.
Microplastics are bad. People are concerned that there are microplastics in your balls! And that this could epigenetically affect downstream generations. I want to test that theory with a real human, not an animal model.
My plan: collect my own sperm samples over time and do whole DNA preps + basic body metrics. Sperm regenerates approximately every 10w, so planning time series over 10w. Next, inject myself to ~10x the average amount of microplastics, directly into the bloodstream. Continue with the sperm collection, DNA preps, and basic body metrics. Nanopore sequence, and see if there actually ARE any epigenetic changes. Eventually I'll go back down to baseline - are there any lasting changes?
Of course, this is an N=1 experiment, but rather than a metastudy I'm directly changing one variable, so I think it is valuable. We should have more people doing controlled experiments on themselves for the sake of all of society - and as a biologist, I actually have the capacity to design the experiments and scientifically interpret the results. In a way, it's part of civic duty :)
This remains uncontrolled and unblinded experiment complicating the interpretation of the results. For instance, can you be sure that any changes you might see are not caused by (e.g., hormonal, behavioural) changes induced by your knowledge that you just received 10x the average amount of microplastics?
if 10x the average amount of microplastics are showing changes that are approximately equivalent to hormonal or behavioral changes, it's not a significant factor to be worried about.
There are many times where unblinded experiments are still valid. And unfortunately, n=1 means that you can't have controls. The question: "did this intervention, in one person, cause a greater-than-normal increase in epigenetic changes, above baseline?"
>Microplastics are bad
I was just listening to something the other day about how there is essentially no way to study this right now, and the most common method of microplastic detection in samples has been proven largely inaccurate.
Is there some reason we think microplastics are more dangerous than the other nanoparticles of inorganic dust we consume and inhale every day? Serious question - Iāve got enough to worry about and this seemsā¦ very low on that list?
yes
Turns out both can be an issue if youāre not āfiring on all cylindersā.
Microplastics in your balls are one thing, but do you have concerns about introducing them in your heart and blood-brain barrier?
eh, not that concerned
Please don't. The fact of this being a sample size of 1 and not being taken seriously because of that should be enough reason not to try it, let alone the health risks. I'm sure there are safer tests you could do.
ok, but I don't think people are injecting them directly into their bloodsteam...
āLook, Iām fine!ā
Godspeed you legend.
