In the middle of a large interactive rebase, you realize the commit list you arranged wasn't quite right. Maybe a commit is missing, or misplaced, or something else.
Where usually you'd have to start over, Retcon lets you course-correct on the fly: your history remains fully editable, always.
Comparison of Retcon 1.4 and Retcon 1.5 icons. The old icon represents a whiteboard, with a small Git branch drawn on it, and a pen resting on top. The icon is generally purple. The new icon is similar, but with fundamental changes. The pen no longer extends outside of the whiteboard, and instead is resting at the center, angled 45°, and is fully contained by the shape of the board. The Git branch is now bigger on the board, and seems to extend outside of it.
The new icon makes the most of the new style and constraints. It pairs well with Xcode's own icon, but remains true to its predecessor, expanding on its design. Hopefully, Retcon will still feel right at home in your Dock!

Retcon 1.5 releases today! It brings an updated UI on Tahoe, a redesigned icon, and an assortment of improvements and fixes. Update from the Retcon menu, or get the app from retcon.app.
(please also update to macOS 26.1, which resolves many system bugs, some of which impact Retcon)
New blog post! Retcon 1.4 got a lot faster. Much of that speed is owed to caches. Straightforward caches, oddly-specific caches, hard-to-invalidate caches, the works. Here's some details about them!
