CodeRabbit

CodeRabbit is an AI code review service for pull requests on GitHub and GitLab. Once installed on a repository, it reviews each pull request automatically and posts a summary, inline comments and suggested fixes.

Reviews can be tuned with review profiles and repository-level instructions, and pre-merge checks can block merges that do not meet defined conditions. Large diffs are explained with semantic diffs and diagrams of affected components. Security scanning runs on pull requests and on schedules, and findings are verified before a fix is proposed. Developers can interact with the reviewer through comments in the pull request.

CodeRabbit is a commercial service with a free trial and paid plans.
