FriendRunner is a cloud-based tool that enables Facebook developers to optimize and test their applications in ways that until now have not been possible. It allows you to run your application outside of the Facebook Platform infrastructure so that you can:

• understand how your application scales under load before it goes viral
• profile your application so you can see how it interacts with the Facebook servers
• customize the demographics of the user base you'd like to test with

We know that Facebook developers run on tight schedules, so we made setting up a FriendRunner test easy to do, and since it's cloud-based, there's nothing to install. It analyzes both Facebook Canvas applications and Facebook Connect applications.
