What it does
OpenRabbit is a pull request reviewer that you add to a repository as a GitHub Actions workflow. It reads the diff, sends it to a language model provider you configure, and posts a structured review made of a plain-language summary plus inline comments or suggestions. Because it runs in your own Actions environment, the page says there is no server to host and that your code is not proxied or stored by a central service. You supply an API key for the model provider and keep it as a repository secret. OpenRouter and Groq are named as providers, and the default setup uses OpenRouter's free model pool, which the page admits is subject to rate limits and can be inconsistent. The reviewer tries to look beyond the diff: it can fetch extra files when it lacks context and reads linked issues. Its review prompts cover mentor-style questions, performance and scalability concerns, security problems such as SQL injection and XSS, and changes that are unrelated to the pull request. The review mode can be summary only, inline only, or both.
