CodeKit â€” THE Mac App For Web Developers
CodeKit helps you build websites faster and better.
CodeKit finally left the beta and I just bought my license. It really is THE app if you are using LESS, SASS, Coffeescript or anything like that. I love it.
Sadly it’s not available in the Mac App Store and only purchasable by credit card.
I also like his approach for pricing CodeKit. Have a look yourself and decide how much it is worth to you.
