Loadster Workbench

Loadster Workbench is the world's easiest way to load test dynamic web applications, websites, and HTTP web services. For Mac and Windows, the Workbench provides all the tools you need to create, configure and execute load tests from your desktop.

Record HTTP and HTTPS scripts from your favorite web browser, using the Loadster recording proxy.

Parameterize your scripts to handle dynamic content with validation rules, response capturing, custom headers and more.

Add custom form data with Loadster's data set editor, or import your user data from a CSV file.

Configure load test scenarios with multiple virtual user groups, to run the same or different scripts simultaneously.

Simulate different bandwidth, parallel connections, and more to measure how end-user settings affect your application.

Run load tests and observe your application's performance in real time with the interactive dashboard.

Generate HTML reports to easily share test results with your team. Loadster's HTML test report has interactive graphs to quickly zero in on bottlenecks.
