LoadStorm provides pure on-demand web load testing. Need to simulate 5,000 users hitting your web application? You could be running that kind of web application stress test in about 15 minutes for a simple scenario.

$39 for 1,000 Concurrent Users!

Our pay per test model provides one test for one hour. See our pricing page for full details. Run performance tests for 100 or 100,000 concurrent users or anything you want in between. Pay only for what you need. Load testing subscriptions cost less than $0.01 per vuser/hour.

Are you sure you want the hassle of buying servers, installing open source, and maintaining the load generation environment? If so, then other load testing tools would be better for you. LoadStorm makes it so inexpensive that it is a bargain compared to the value of your time wasted with open source load testing tools. You should be focusing on your web application to improve its performance.

Think about how much your time is worth. You get paid because you deliver value to your customers. Nobody else can performance tune your application, but we can greatly simplify your performance testing. Use our load testing tool and get started in minutes.

Create as many test plans, scenarios, and steps as you need. You can simulate virtual users logging into your system, purchasing with credit cards, going through specific links, and randomly clicking through the site. Our load testing tools are:

Loved by Developers

Read our testimonials from hundreds of programmers, testers, and product managers. We solve their load test problems.

Pay per test or monthly subscription (no annual commitment). Subscriptions provide unlimited test runs per month.

During performance test runs, real-time graphs show you the key metrics such as Average Response Time, Error Rates, Throughput, Requests per Second, and Concurrent Users. This first graph shows volume being loaded to the target domain in a linear pattern. The second graph below shows the metrics for the same test.
