Web Performance Results in Half the Time

Get accurate load tests in just minutes, using real browsers in the cloud.

Traditional load testing is difficult. It doesn't have to be.

Traditional load-testing tools create performance test scripts for your websites and web apps by recording HTTP/S protocol traffic. This results in massive scripts that are hard to read, and running them requires correlation – capturing and storing dynamic values from the server to use in later requests. It’s a complex process, and a big part of what makes performance testing so time consuming.

LoadNinja makes load testing simple and fast. Test your website and web apps on real browsers, in the cloud, without the need for dynamic correlation.

Efficient: Record & Instantly Replay Load Tests

Cut script creation time from hours to minutes using our InstaPlay Recorder. No coding or correlation needed, even with complex transactions.

Accurate: Load Test With Real Browsers at Scale

Generate realistic load using tens of thousands of real browsers for data that accurately represents your end users. No more load emulators.

Actionable: Browser-Based Metrics & Diagnostics

Evaluate navigation timings and other data, sourced straight from real browsers in your load test. No more digging around for data.

Real-world examples from real users

Right off the bat, just the ease of generating a script running the script, the fact that you can generate load from servers in the cloud to test private applications was really simple. LoadNinja was able to point out 3 or 4 areas that we had bottlenecks that we said okay that’s an indicator that we can go in and fix. We were able to make our response times faster and customers happier
