I try to login with GitHub and get an "Incorrect login" window. It works after I confirm my email, however.
Anyway, this may be good, but the interface is kinda heavy, don't you think? Also, it seems that the "blueprints" should be written in JSON or whatever, something a programmer must write. If you're not offering flashy interfaces with click buttons and you only want programmers, perhaps you should just offer a CLI interface.
