About OpenRabbit

OpenRabbit is a free, open-source GitHub Action that reviews pull requests. It runs completely in your own GitHub Actions environment, so you do not need hosting or a separate server to manage. On pull request events, it analyzes the diff and posts a structured review. It works with pluggable LLM providers such as Groq and OpenRouter, and you store your LLM API key as a repository secret.
