Ask HN: What Are You Working On?

https://crit.md - a CLI tool for reviewing AI coding agent output like a GitHub PR.

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 :)

I have been building on 3 tools lately all opensource-:

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

https://github.com/ojuschugh1/claimcheck

1. https://flopper.io - a resource to find AI infrastructure benchmarks and soon - compare providers. Reach out if you're a provider!

2. https://boulderinglist.com - a catalog of climbing gyms across the world

3. https://livedsupport.com - AI driven support for colorectal issues

4. https://radiusing.uk - find where people are willing to do something to improve the social fabric of where they live

5. https://llmstxt.studio - generate rich and full llms.txt files for your website. Then we check if AI queries would cite you based on this.

6. https://probe.bike - aggregate and tell stories with your cycling data

7. https://paletter.dev - a color design system for the modern era - based on design systems

8. https://llmstxt.work - a directory of llms.txt files

Probably working on too many projects at the moment - but really enjoying building again.

Working hard to figure out how to market, interested in trying to push things out a bit more.

Working on a benchmarking tool with https://flopper.io for GPUs too - written in Rust - which should allow me to try to get people to submit their general flop values for consumer hardware to run local llms/models.

Any feedback super welcome!

https://spendboard.app - local-first budgeting mobile app, can be used on any number of devices offline, synced when online. Been building it for almost 3 years now (the most difficult part was the conflict resolution strategy)and happy to finally release it. :)

VERDURE is still a creative plant-generation sandbox where you grow and sculpt stylized trees.

https://outcron.com - hosted tool to schedule health checks, webhook calls, & container executions

As an SRE, DevOps Engineer, and Platform Engineer, I've always wanted an external place to run scheduled executions of miscellaneous utilities -- checking in on a URL, running an SSL check, verification of DNS from outside, etc. REST API-centric with CLI tool and web UI control near-parity.

Backend and CLI are Golang. Frontend is React. Simple architecture--a bunch of aarch64+amd64 hosts run `outcrond` and use a shared PostgreSQL and Valkey/Redis.

I'm building a robust sandboxing environment for AI agents.

It supports multiple sandboxing backends such as docker, podman, kata, firecracker, and for Mac seatbelt and tart.

Any agent is in theory supported, but it has specific support for Claude, Gemini, codex, aider, and opencode.

Your workdir is never touched by the AI, nor is your system. It doesn't have access to your secrets (beyond what you've explicitly given), and you can restrict network access.

You move changes back to your workdir using diff and apply, so you choose which changes to keep.

I use it for all my agentic work, and couldn't go back to using Claude without it.

I am working on a P2P VPN app that lets you route your traffic through a friend's Internet connection easily. It has a few distinct uses, but right now I am testing whether emigrants from authoritarian countries will be interested in providing censorship-free connectivity to their family/friends at home.

It's called Spora: https://spora.to/

The current MVP is about 90% vibe-coded while being a fairly sophisticated piece of software.

Building Sensonym (https://sensonym.com), a vocabulary learning app that uses phone sensors (gyroscope, camera, mic, accelerometer) to create physical interactions tied to word meanings. Based on embodied cognition research. I've just launched it on iOS and Android in Germany with support for 10 languages.

I'm working on Leedlime[1], a social listening tool that monitors high-intent conversations, product mentions and competitor mentions online.

Notifies you via Slack or Discord.

AI chat for DollarDeploy (platform to automate DevOps, kind of like Vercel for your own servers). Adding more tools to deploy your apps and soon sandboxes.

Working on small improvements to my hacker news search engine:

The garden.

Ha! All jokes aside testing some different local dev workflows, so much cool AI tooling about.
