Welcome to Robin
Free AI code reviews for every pull request. Install in minutes with your own API key.
Robin is a free, open-source GitHub Action that reviews pull requests with AI. You bring your own API key, including free OpenRouter models, and Robin posts findings like a teammate left comments.

npx robin-reviewNo npm? Install with curl instead:
