Spot the differences. Merge in seconds.

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

When you want the absolute very best...
I know, I know, but that price, man. But trust me, people, this ‘diff’ application is the Apple of ‘diff’ apps. It is hands down, flat out the best of the best of all the ‘diff’ apps out there. It is drag ’n’ drop dead simple easy. It will color code your file’s changes and show you EXACTLY where the changes are. It will even let you modify the changes from one file to the other. This is one of those apps that’s “cry now because high price, laugh with joy later because it became your new best friend”.
