GitSage is a GitHub code ownership mapper for engineering teams. It connects to a user's GitHub account, lets them choose repositories they can access, and computes ownership across files and folders from recent commit history. The app highlights leading owners, bus factor, and high-risk modules so teams can answer questions like who should review a change, who understands an area best right now, and which modules are too concentrated around one engineer.
The product is split into a Next.js app for UI, auth, server actions, and read APIs, plus a Supabase-backed analysis runtime. Supabase handles auth, Postgres storage, and queue-backed job dispatch, while Supabase Edge Functions process repository analysis jobs and persist immutable snapshots. GitHub OAuth through Supabase provides scoped repository access, and Octokit powers the GitHub API integration.
