Mac OS Developer Tools
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
"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
