How does it work?

Loadster has two parts: the Loadster Workbench and the Loadster Engine.

Loadster Workbench has all the tools you need to record scripts, build load test scenarios, and run load tests.

While a test is running, it shows a dashboard with live stats and graphs to tell you exactly how your application is responding. Afterwards, the Loadster Workbench makes it easy to export a test report to share with your team.

Loadster Engine is what actually generates load against your application. Install multiple engines on separate machines and control them all from Loadster Workbench, to simulate hundreds or thousands of concurrent users.

The Loadster Workbench comes with a built-in engine that can simulate up to 25 concurrent users, free of charge.

Deploy to production with full confidence

Applications usually fail under peak traffic conditions. This is the worst possible time to fail! Avoid expensive downtime by simulating peak traffic conditions ahead of time, so you can find the breaking point before your customers do.

Simulate real-world conditions

Web apps sometimes perform very differently under load, and the only way to isolate bottlenecks is under heavy load. Tune effectively by simulating real world conditions, and measure the impact of each change you make.

Stop crashes, before they happen

By knowing when and how your application is going to break down, you can make sure your environment has what it takes to scale effectively. The best way to handle high-traffic events is to plan for them ahead of time.

The better choice for real web apps

Loadster makes automated testing easier by effectively handling user sessions, cookies, custom HTTP headers and more. Capture dynamic values from the response and reuse them in your scripts.
