What is it?

GitComet is a desktop Git client that aims to stay responsive on large repositories, such as Chromium-sized codebases, when browsing history and file diffs. It covers everyday workflows including remotes, pull and push, staging, commits, worktrees, branching, and multi-repository browsing, with inline and side-by-side diffs and 2-way and 3-way merge tools.

The open source edition includes Git LFS support for file status, content downloads, locks and tracking, and git-annex support for content get, drop, copy and move. It can also serve as a difftool and mergetool for Git, with a headless mode for scripts and a GUI mode, and it accepts KDiff3 and Meld invocation forms as a drop-in replacement. Optional commit signature verification works with gpg and ssh-keygen.

The application is written in Rust, uses the GPUI UI framework, and ships built-in and custom themes. It requires a local Git 2.53 or newer.
