Subversion is a free/open-source version control system that is popular among developers. It manages files and directories and the changes made to them over time. What this does is allows you to recover older versions of your data, and examine the history of how that data has changed.
Doing this is traditionally a command-line affair, but there area a few GUI applications out there that are changing that.

Still in Beta, Versions gives you a much nicer interface for interacting with your Subversion Repository. This can be particularly helpful if certain members of your team aren’t familiar with Subversion - or the command line.
The only real problem with the application is that the developers have yet to reveal what the final pricing for the application will be. It’s not really something that you can get too excited about - until you know what kind of costs you’re talking about when its all said and done.
Fortunately, there is another alternative.

Cornerstone from Zenna-ware is out in version 1.0.3 and it not only serves as GUI for Subversion - it actually has the ability to create Subversion Repositories built in - with no command line required.
The software is available for a 14-day trial, and will cost you $59.

Versions- Web site came out well over a year before they actually launched a Beta. The beta feels like it's moving slowly too. At last check, I don't think there's a forum where beta testers can review known issues or discuss features. I just got tired of waiting. Also, the interface goes beyond simple and feels a bit simplistic to me. I consider myself a average SVN user and there were options I needed that just weren't there in Versions. It's not a BAD product, its just not that great.
Cornerstone, on the other hand, felt industrial, snappy, and polished. The diff tool is great. SVN cleanup, SVN exporting, handling of general network errors, and searching by applying filters all felt intuitive and solid. Sure it's $60, but if you use SVN every day then I'd think it's worth the $ for a mature SVN client that runs as a native Cocoa app.
Versions would be a close second, but for me the clear winner was Cornerstone. September 25th, 2008 at 1:11 am

The best part, it is a free, open source project.
