GitComet is extremely fast GIT Gui

March 18, 2026 GitComet Launched!

It’s a fast, local-first, open-source Git client for Linux, macOS, and Windows. We started building it after running into the same problem over and over: Git tools felt fine on small projects, but got painful on large repos and big diffs.

Project main focus is speed:

  • It can open Chromium repository blazingly fast 😂 (in less than 1 second)

  • It can diff 50mb file with syntax highlighting without lagging

  • Memory usage stays within few hundred MBs at all times

  • Its fast to pick up as user interface follows familiar tools like GitKraken, SourceTree and Github Desktop application

If you try it, We would love to hear feedback! Also if there are developers who would like to contribute PR's are welcome.

About

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.
