Ask HN: What are you working on? (April 2026)
Vibe coding, games, creating next Google? Let us know.
I'm building a pipeline that monitors various sources for changing information, and creates a pull request or an email notification when something changes. For example, it triggers an update to constants.json if the income tax threshold (§ 32a EStG) changes. It sends a daily email digest of relevant discussions in relevant communities. The goal is to lighten my workload and improve the quality of the information I share.
This is my first coding project where I use AI. I use Claude Code on a tight leash to write the code, and ChatGPT's smallest model to extract numeric values from monitored pages.

The git branch: https://github.com/All-About-Berlin/aab/tree/ai (under /monitor)
1) Etch-Detect API changes automatically using real traffic (no tests required)
https://github.com/ojuschugh1/etch
2) GhostDep-Detect phantom and unused dependencies across multiple languages using a fast Rust-based CLI
https://github.com/ojuschugh1/ghostdep
3) a local CLI that verifies whether AI coding agents actually did what they claimed
I'm a senior SEO at Intuit with 25 years in search and zero engineering experience. I built the whole thing using Claude as my coding partner — React SPA, Netlify serverless functions, Supabase, Google Calendar OAuth, Stripe. The hardest part wasn't the code. It was figuring out that AI styling advice is useless without a database of what the person actually owns, which is a solved problem once you think about it that way.
Launching on Product Hunt next week: Wednesday, April 8.

I got frustrated with Claude Code and Cursor producing plausible-but-wrong changes with no easy way to annotate and push back, without making a full PR. crit makes the review stage fun again!
Works on both plans as well as code itself. It’s been very rewarding hearing from folks who use it, everyone has been very kind! My most successful side project already :)

BYOK — uses your own Claude/OpenAI/Mistral API key, so text never touches a third-party server.
Neat thing about AI chat is that you can write in any language and it will automatically translate and use the right tools (create VPS server, build and deploy app).
It is not only isolating with a git worktree but also all other context related to this task (previews, reviews) and allows the agent to interact with this context via notifications and so on.
There's no engine, no physics lib, just a requestAnimationFrame loop and chill music.
The dev highlight so far has been 30 players in the first 48 hours and already having to sanitize racial slurs from the leaderboard smh.
