Open-source AI PR reviewer that helps you ship

Nitpicker launched as a free, open-source AI pull-request reviewer that runs on AWS Lambda, Cloudflare Workers, GitHub Actions, or a self-hosted server, and is installed via a curl script at nitpicker.dev/install. The tool's marketing claims it is lightweight and token-efficient, keeps private diffs on the user's own infrastructure so "your PRs never become someone else's training set," and posts line-numbered comments on code such as a duplicated session check and a swallowed Stripe charge error. The project positions itself as a self-hostable alternative for teams that want automated diff review without sending code to a third-party vendor.

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.
