LoadStorm™ is a cloud-based system for web load testing. Web developers, product managers, and performance testers have often asked if there is a more cost-effective way to generate tens of thousands of concurrent vusers without the hassle of open source software. The answer is yes.

Easy, inexpensive, and massively scalable.

Let us "storm" your web application with very heavy traffic volume of many user types and scenarios.

Using our web load testing tool, you can simulate real users on your website or web application. No hardware, no download, no server software to configure, and no scripting language to learn.

PROVE IT WORKS - FOR FREE!

Sign up for a Breeze account, and you can run unlimited load tests with 25 concurrent vusers all month, every month at no charge. Not a trial...it is free forever. You have nothing to lose.

Hurricane accounts with 5,000 vusers can cost less than $0.01 per vuser/hour.

LoadStorm utilizes Amazon's EC2 cloud to dynamically allocate load generation servers based on our customers' needs real-time. Our apps ramp up instances for your 100,000 vuser test, then ramp down within minutes. We never waste resources - that's how we save you money.

LoadStorm - your tool for load testing websites. Cheap. Easy. Period.
