Best unity collaborate alternative? (Source Control)

Unity Collab is not going to be free anymore, we need help finding an alternative. Github seems to be prevalent, but we don't have the money to afford either. Our game is 10 gig's in size, its fairly large. We have a team of 7 to 8 developers who use this, what would you all advice we do?

 

Do a quick search on the forum for other threads where this was answered. ;-)

Visual Studio Team Services is only free for teams of up to 5 developers, so that's out unless you want to pay for the extra people.

A common answer was to get a cheap Linux hosting service. You can often find sales for as low as $2/month with unlimited disk space. Then install git. You can also install a wiki system if you want to maintain a wiki. If your team already has a website, you might be able to simply use that server.
