Subversion is arguably the world's most popular source control system, and many a developer's best friend. It keeps things organized, it helps you gracefully recover from your mistakes, and it makes managing branches and versions of your projects dead simple. What isn't always dead simple is setting up or managing the Subversion repository. Sure, the software is free but, your developer's time definitely isn't. If you've delegated the hassles of managing your source control to one of your senior developers, you're likely making a crucial mistake that is costing you money.

Beanstalk takes the burden of setting up and maintaining Subversion out of the equation. For $15 a month and up -- or free for a tiny project not needing per-commit backups -- Beanstalk gives you Subversion as well as integration with Twitter, Basecamp, Campfire, and more. Use any Subversion client you want! Cooler still, if you're using Beanstalk's SVN to manage a website, they've made it super simple to set up FTP deployment on commit, so every time you commit a change it can go live on your domain.

For cost to hassle ratio, I personally have to say spending $15 bucks a month for someone else to worry about keeping my Subversion server running and backed up might be the best $15 I've ever spent.
