There is this ci project I’ve been following with some interest, sadly I havn’t had the chance to try it out since it’s only for open-source software. It seems however, that that is about to change!
They are opening up a beta access program for Travis-CI, which I think is really exciting!
Here is a link to sign up, and there seems to be some sort of pyramid scheme going on to get access to the beta. So sign up using this link
