Spot the differences. Merge in seconds.

With text merge, three-way merge, folder comparison, and now the ability to ignore whitespace-only differences, Kaleidoscope integrates perfectly with the version-control systems you already use.

Who says powerful developer tools can’t be beautiful too?

Praise for Kaleidoscope

As a LaTeX user, this app really helps my work. - When I revise LaTeX manuscripts, this app shows the difference between the original and revised version in a way that is not only fancy, but also easy to understand. I am really satisfied with this app.

Version 2.0.2
Review by skoskie

Like dating a super model - It’s beautiful. Says so several times in the description. But it doesn’t actually do a great job of diffing. It will often mark a line as changed, when it should clearly be be marked as one deleted and one inserted line. When this happens, it throws off the rest of the document. There is no way to manually mark a line to prevent this from happening. You just have to get as far as you can in Kaleidoscope, then close it and either finish your work in a different diff app, or manually make the changes in a text editor. For $70, that’s rediculous. I need more than beauty. I need it to work as intended, and the fact that it often doesn’t is really frustrating.
