A cozy desktop Git client that pins a snapshot before every mutation — so ⌘Z always works. Free and open source, on macOS, Windows and Linux.

The Safety Manager
Every Git GUI makes it easy to run a dangerous command. GitCat is built so you can take it back — every mutation, all the way down, including the ones git itself considers final.
Before
Refs, index, worktree and stash — captured before the command runs, not after it goes wrong.
During
Anything irreversible needs a typed confirmation, and tells you exactly what it will touch.
After
One keystroke, any mutation. Undo is itself a snapshot, so you can undo the undo.
Commit graph
git2 reads and a hand-tuned Rust swimlane layout, streamed onto a virtualized canvas with no depth cap. 150,000 commits scroll smoothly — with the text still readable.
Diffs & staging
Stage by file, by hunk, or by individual line. Text diffs are syntax-highlighted; images and PDFs get a real before/after preview, rendered natively and zoomable.
Command palette
⌘K fuzzy-searches commits, refs and actions at once — including branches that aren't in the sidebar. Search by author, by full hash, or pickaxe through file content.
And the rest of it
Merge, rebase (linear and drag-to-reorder interactive), cherry-pick, revert, bisect, blame with rename-following, submodules, patches, and a git-filter-repo wizard.
A real 3-way editor with hunk-level resolution, plus rerere and your own external merge tool if you'd rather.
Reflog rescue and dangling-object recovery, for the commits git itself has already given up on.
Extend GitCat with ⌘K commands, hooks, side panels, named tools, and Tama skins and reactions.
The whole interface in three languages, switchable live with no reload.
Open a repo from your terminal the way code . does — WSL-aware, on every platform.
Meet Tama
Eight expressions, wired to real moments: curious while you search, thinking hard mid-rebase, genuinely alarmed right before something irreversible — and celebrating once it's safely done.
That's rather the whole idea — nothing it does to your history can't be taken back.
