Every change in one window
Pick any two branches: the one you work on and a target to compare it with. Diffloupe shows every change between them, and keeps the view current while you work.
Changes list
Staged, changed and new files in one list that refreshes as you edit.
Word highlights
Changed words stand out inside each line, and unchanged code folds away.
Branch log
Only your branch's own commits, with merges from the target shown as dividers.
3-pane merge
Yours, the result and theirs side by side when a merge has conflicts.
Built around the review
Changes, diffs, history, documentation, merges, commits and a terminal. Eight views in one window, all reading the same repository.

What is Diffloupe?
Diffloupe is a Mac app for reviewing git changes. It shows what your branch changes compared with the branch it will merge into, with side-by-side diffs, the branch log, rendered Markdown and a 3-pane merge window.
What do I need?
A Mac with Apple silicon and macOS 13 or later.
Why install with a Terminal command?
Diffloupe is not notarised by Apple yet, so macOS stops a copy downloaded in a browser at its first start. The command installs it without that dialog, and it checks the download first.
Where does my code go?
Nowhere. Your repositories and settings stay on your Mac. Diffloupe is open source, so you can check every line of what it does.
How do I update?
Diffloupe tells you when a new version is out and installs it with one click, keeping your settings. Running the install command again works too.
How do I remove it?
Choose Uninstall Diffloupe… in the settings menu. It removes the app and the data it stored.
Review your next branch in Diffloupe
Install it with one command, open a repository, and read every change before you merge.
