Beak

Beak is a cross-platform developer tool to make it easier to build, test, and research API's. We've tried to focus on building an application where the interface is simple and intuitive, but at the same time has a huge feature set that makes all aspects of API development easier.

Beak tries to be as un-opinionated as possible, instead of trying to guess how your team works, Beak projects are simple folder and file structures, so you can fit it into your existing Git workflow however you want.
