Browsershots runs your supplied URL through a metric plethora of browsers, on assorted platforms, and then provides you with screengrabs on how it looks! They seem to have a bank of virtual machines doing the real actual work, and you are placed in a queue, but it’s certainly easier than installing all the OSes and browsers yourself.

I was surprised to see that this very blog not only broke on some systems, but actually killed the browser. Now that’s power!
