Load Testing in the Cloud

Load Testing Tool

load testing toolSTORM your web application with virtual users. LoadStorm is a tool for hammering your site with http traffic and measuring the results from the users' perspective.

Many developers don't load test because they can't afford the tools, the hardware, and the time for a learning curve associated with a new tool. We've had that problem (need it, but too expensive), so we created a solution.

Easy. Massively Scalable. Affordable.

With LoadStorm, it is easy to create various scenarios of user activity with an assigned virtual user volume on each scenario. For example, a load test can be created to hit your server with 100 concurrent browsing users that randomly click on links. Then, the load can be increased by 100 users every 10 minutes until the total expected user load of 1,000 users is reached.

You can be running a load test examples in 5 minutes and against your site within an hour. Sound too good to be true? Give it a try. You have nothing to lose.

The results from the test are presented in real-time charts and graphs showing key metrics over elapsed time:

  • Number of concurrent users
  • Requests per second
  • Average response time
  • Peak response time
  • Error rate percentage
  • Throughput

Load Testing Tool Results


LoadStorm supports having many scenarios in a test plan with several steps each. For example, you may have 80% of your traffic browsing products in your catalog, while 15% are making a purchase, and the other 5% are performing admin such as entering records or running reports. With LoadStorm, you can conduct volume testing on each activity and simulate various types of users moving through your web app.

If you find that LoadStorm is a fit for your load testing requirements, you can run tests up to 25 concurrent users forever for free. Once your test plans work the way you want, and you want higher volume, simply click the Upgrade Now button and pick a subscription or Storm on Demand that has the virtual users you need. Our pricing is simple. Upgrading is easy. No commitment.

Can you afford $0.01 per user hour of load testing?
