Baloo Bear

Baloo Bear: Self-hosted AI code review agent for GitHub pull requests that reads project context and catches logic bugs.

Baloo is an open source GitHub App that reviews pull requests automatically. It reads diffs, explores repository files, and posts actionable comments to catch bugs, security issues, and guideline violations. Teams host the service themselves and provide their own model API keys for providers like Anthropic, Google, and OpenAI. It supports custom review briefs, severity routing, and discussion tracking across iterations. The platform also offers an optional PostgreSQL-backed review history dashboard.
