Load testing doesn't have to be difficult.

Traditional performance testing has always happened in the protocol layer. This results in massive tests that are hard to read, require extensive programming, and take hours, even weeks to set up. Even the results aren’t even indicative of the real world as they test the protocol.

No wonder performance testing seemed hard.

But it doesnt have to be with LoadNinja. Instead of testing the protocol, test the actual end-user experience across tens of thousands of browsers using our TrueLoad technology, saving you over 60% of effort. No maintenance or setup required to give you the most accurate understanding of performance in the least amount of time possible.

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
