Why GitComet

Built for large repositories and fast review loops

GitComet started from frustration with existing tools on huge codebases like Chromium. We could not find a product that stays responsive and functional when browsing large repositories and file diffs.

The app is designed for developers who spend real time in commit history, diffs, merges, and branch cleanup. Instead of hiding Git behind abstractions, GitComet keeps core workflows familiar and makes slow tasks feel immediate.
