Looking for alternative Collaborative Developing Environments [closed]

Question

I'm interested in Collaborative Developing and I was wondering if there are alternative solutions than using UNA (example video) from N-Brain. Free would be even better, but I guess that's not an option which such technology.

PS: The main future I'm looking for is working real-time with multiple persons in the same code.

Answer 1

If you're in Mac world, SubEthaEdit is a good option. Not free, but €29 isn't bad.

Answer 2

After some further searching around I have found Gobby, seems to be much better than MoonEdit.
Don't think there is any better free program that supports developing more than color coding.

I hope to have helped others too by this question.

Answer 3

Thanks to Charlie I have found MoonEdit, I'm still looking for better alternatives though...
