Kaleidoscope

Now with text merge, 3-way merge, and folder comparison, Kaleidoscope integrates perfectly with the version control systems you already use.

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

Praise for Kaleidoscope
"Kaleidoscope epitomizes the concept of “versatile software”: anyone can pick it up and use it, and the app will “scale” according to a user’s needs." - Federico Viticci, MacStories.net

"Kaleidoscope 2 is breeze. I wish I'd had something like Kaleidoscope when I wrote my first novel, and I'll be counting on it when I finally get around to writing the next one." - Rene Ritchie, iMore.com

"It’s beautifully designed, fast and wonderful to use. It’s become an essential part of my toolkit already." - Matthew Panzarino, The Next Web
