Cool Tools 23: LoadImpact

This is a great one – thanks to Brendan Patterson for this find!

LoadImpact is a load-testing service with a free offering that’s immediately available on their home page with no sign-up necessary. It’s an excellent load testing tool that utilizes the Amazon cloud to stress your site from multiple locations, and it’s got a really slick UI. I haven’t tried the paid version yet but welcome any comments from any of you that have explored some of the more advanced features.

Pro Tip for you portal users utilizing the free version: the URL you enter doesn’t process any JavaScript or some redirections on the URL you provide, so instead of using, you should use

Amazing how just a couple of years ago load testing tools would have costed a fortune (and many that will remain nameless still do!) – kind of like .NET Decompilers
