I’ve been using Assembla for some time.
Like they say: "Assembla is an integrated system for agile team management, collaboration and coding. You select best-of-breed tools like Subversion, Git, Mercurial and Trac with Assembla's issue tracking, notifications, and workflow."

A nice benefits of Assembla was the ability to have free SVN repositories. It was free until october 2008. Now they are restricting free plans.

They have offered a product for free. And now they ask you to pay or in alternative all your data will be public. Not so good!

Is there a good alternative to assembla?

I suggest you these:

1) Origo
2) XP-dev
3) Dejavu
4) Bitbucket
5) Unfuddle

What do you think?
