Browsers-based load testing

Simulate real user actions in each browser instance.

We give you clear and comprehensive optics on how your website performs under real-world loads and conditions. This makes it easy to pinpoint and eliminate bottlenecks that protocol-level analysis misses.

Integrate seamlessly with your existing Selenium tests.

Send requests to our API via our Java libraries, or using your own scripts in any programming language. Just specify the testing parameters and load you’d like to use — and see results in real time.

Real-time statistics

Track and analyze statistics in real-time.

Our platform captures Raw Data from every concurrent browser instance, refreshing every 15 seconds — making it easy to notice bottlenecks and other anomalies as they occur, or terminate your test and directly address an issue.
