A linter for production readiness

We've broken production too.

That's why we built a linter that flags incident-class threats—the bugs your tests and reviews happily let through.

See what reviews miss

Unhandled errors. Unbounded retries. Race conditions. The stuff that compiles but blows up at 3am.

Fix before you push

Not a runtime monitor. Not an observability tool. Just fast feedback where you code.

Your code stays yours

We analyze in memory and discard immediately. No code storage. Respects .gitignore.
