What are you working on? Any new ideas that you're thinking about?
Comments
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.
For the past 2ish months, I’ve 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]

Building a tool for finding scientific papers behind real-world OSS projects: https://papergrep.dev/
This is a follow up to an idea I had years ago https://news.ycombinator.com/item?id=13022649, which is now semi-automated (with lots of manual curation as the last step).
The biggest challenges:
- how to organize all this info in a nice way
- where to find more time to read all the gems I've found so far :)
UPD: formatting
I released an open source library to remove metadata from images: https://github.com/fasouto/picscrub
Was more complex than I thought. Still missing support for some RAW formats and had to fix some bugs
I also created a website to showcase how it works -> https://picscrub.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.
https://github.com/jmahmood/RED-STAR-WEIGHTLIFTING https://github.com/jmahmood/WEIGHTTRAINING-EDITOR
Ultra token efficient query language for LLM generation. Acts as an intermediate representation that programatically translates to SQL.

Letterboxd for music - https://raygum.com
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.
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...
https://taiko.taikohub.com - Working on the TAIKO-01, a split concave ergonomic keyboard.
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.
Working on a few
- Kardy - send group cards - https://www.kardy.app
- Jello - Create & customize popular games - https://www.jello.app
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?
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.
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 don’t 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.
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
Hi HN, I'm working on https://waitle.io — a simple waitlist & coming-soon page builder.
Plenty of competitors exist, but many are surprisingly expensive for such a simple use case.
This started as an attempt to create a more reasonably priced alternative for early-stage projects.
I finished website[1] with solitaire games as my first project which I did from start to end, from coding to people online playing my games.
Currently building chess puzzles based game called ChessBingo[2]. It's almost finished, but there are still things to polish.

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.
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.
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
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
Last week I released Gata Router - https://github.com/gata-router
Gata is an open source automated L1 ticket triage tool for Zendesk. It costs pennies per ticket for it to route tickets to the correct team.
During development I was regularly seeing over 90% accuracy. The average for humans is 60-80%.
The whole thing runs in your AWS account.
There's more information in the release announcement - https://www.proactiveops.io/archive/meet-gata-the-automated-...
I am building Hobbyboard as a self hosted visual archive that uses vision models to curate inspiration media for hobbyists and makers.
Website: https://hobbyboard.aravindh.net
GitHub: https://github.com/aravindhsampath/hobbyboard
I want to do a show HN later this week.. but here might be a softer launchpad :-)
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.

"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.
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?
Working on i18n for Val CMS, a lightweight CMS where content is stored as code.
GitHub: https://github.com/valbuild/val/blob/main/packages/next/READ...
I built a website where kids can practice reading comprehension and learn new words while staying up to date with the latest global news each day. I originally built it for my own kids to help them maintain their reading skills while we travel. They loved it—and even suggested adding gamified features like streaks and badges!
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.
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).
I’ve 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.
It’s intentionally not real money and not a financial product — more like infrastructure for coordinating agent spend safely. Mostly exploring how much autonomy you can give agents before cost becomes the real bottleneck.
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:
- Life’s 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 spent my weekend building asterbot: https://github.com/asterai-io/asterbot
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.
Maintain my blog
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.
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 :)
Kerns (https://kerns.ai) — 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.
Puzzleship - https://www.puzzleship.com/
It's a daily puzzles website focused on logic puzzles at this moment. I have about 70 subscribers, and it's online since Dec/25.
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.
Last time this was asked I was working on this
https://github.com/fmstephe/simd_explorer
A little TUI app for interactively running different SIMD instructions and seeing the outputs.
Since then I have completed the tool for AVX/2. At this stage that's as far as I intend to go.
It's potentially valuable as an interactive quick reference guide for SIMD instructions.
It works on Windows, Linux and with the right environment variables it will successfully pretend to be AMD64 running on an Apple M chip.
Arm NEON instructions are not supported at all, currently Go's assembler does not include these instructions directly, so I didn't attempt to build for them. Maybe one day.
Next up, learn Zig - be happy.
I'm working in getting my fullstack web framework Andurel to v1 (currently in beta).
The goal is to approach the developer experience you get from Rails, but in Go, while keep as many of the idioms from Go.
I'm working on Cyclonauts (https://cyclonauts.net), an addon for Strava to make your commute more fun.
It maps your cycling activity data against the OpenStreetMap catalogue to generate all kinds of exploration statistics.
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.
An iOS build size analysis app that runs locally on your Mac: https://apps.apple.com/us/app/dotipa/id6742254881
Working on platform around Exercise Snack concept: https://1minuteworkout.org/.
Basically it's a browsers extension: site blocker + ultra short workouts. To break 8h sitting.
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.
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.
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.
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.
Bedtime Bulb v2 [0]: a low blue light bulb for use before bed, with added near infrared. Now shipping!

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
A fun quiz for identifying AI content on Wikipedia. Decided a game format is more interesting than markdown.
