Show HN: Vibecheck – merge gate that checks you understand your AI-written code

Good evening folks, I built Github merge gate which that checks whether developers understand their own code when they create a PR.

I kept getting sent PRs to review where it was obvious the author had pasted the ticket into an LLM and called it a day.

It's self-hosted (so you can use it in your enterprise environments or privately)

It is BYOK (Anthropic) obviously.

I have two demos in the pull requests here: https://github.com/bhurghundii/vibecheck.dev/pulls - you can see what Vibecheck does (it blocks a PR for clearly showing no attempt vs a PR which gets it right)

I would love feedback, especially from anyone dealing with a similar problem. I do use it for my own projects a lot so expect improvements.
