GitComet

GitComet is a Git client built entirely in Rust, targeting developers who work with large codebases and need a GUI that stays responsive under real-world conditions. It runs on Linux, macOS, and Windows with a local-first approach: your repository data stays on your machine.

The project started from frustration with existing tools on massive repositories like Chromium. Most GUI clients slow to a crawl or crash when browsing deep history or large diffs. GitComet opens the Chromium repo in about one second on Linux, compared to 18-25 seconds for tools like GitKraken or SmartGit in the same benchmark.

The core open source edition covers a full desktop Git workflow:

• Staging and commits with inline and side-by-side diff views
• 2-way and 3-way merge tools as a drop-in replacement for your existing mergetool config
• Worktrees and branching with full history browsing
• Multi-repository browsing across projects
• Remote operations including pull, push, and fetch

The familiar workflow angle matters. GitComet doesn't try to reinvent Git concepts or hide them behind abstractions. If you're used to standard Git terminology and tooling, the transition is straightforward.

A paid Professional edition is planned for teams wanting GitHub and Azure DevOps integrations, code coverage workflows, and CLI integrations. The open source edition is free for personal and commercial use with no restrictions.

Built on smol, gix, and gpui, the app is genuinely fast rather than just claiming to be. For developers who spend serious time in commit history and diff review, that difference is noticeable.
