LoadStorm is a performance test tool that applies heavy loads of HTTP traffic. We provide web developers clear measurements regarding their applications such as Average Response Time, Requests per Second, Throughput, and Error Rates.

Hit your site with 50 or 50,000 concurrent users that take realistic actions such as logging into your application with a test file of your own test usernames and passwords. Use random linking to get broad coverage of traffic patterns. Get a spreadsheet of every request/response pair.

Why has LoadStorm become the new leader in on-demand load testing?

• It solves the problems with cost - everybody can afford it.
• It saves time - simple to build test scenarios without scripting.
• It eliminates hassle - no download, no install, no configuration, no hardware needed.
• It delivers key performance metrics - see them in real-time graphs.
• It makes web developers happy - testimonials continue to pour in from customers.
• It is guaranteed.

Graphs like this one show you quickly how your load testing is ramping up virtual users. You can see how many requests per second are being generated in relation to the kilobytes per second of throughput moving between the browsers and your servers.

Our performance testing tool is built on the Amazon EC2 cloud computing infrastructure, so we have the horsepower to deliver your largest load tests. We offer a free plan and two ways to buy. Monthly subscriptions give you unlimited test runs, and Storm on Demand allows you to pay per test.
