Choose Codex or Claude Code when you log in. Each review uses your selected plan. Change the prompts, model, reasoning level, and limits in your self-hosted deployment when you want to change how it reviews every installed repository.

Install your GitHub App

Deploy OpenBugbot in your own Cloudflare account, then install your GitHub App on the repositories you want it to review.

Open or update a pull request

A non-draft pull request sends a GitHub event to your Worker. The Worker queues a review and starts an isolated container only when there is work to do.
