The open-source AI PR reviewer that helps you ship.

AI that reviews GitHub PRs like the coworker who actually reads the diff — then leaves comments you’ll think about in the shower. AWS Lambda, Cloudflare Workers, or GitHub Actions. Costs pennies. Costs pride.

Nit standing, unimpressed

mascot · do not feed after midnight

Meet Nit. One eye. Many notes.

Born in a failing CI job. Raised on bad diffs. Exists so humans can fight about product instead of console.log("here2"). Does not do pep talks. Does do line numbers.
