A simpler approach, more thorough data

Create Test Scripts in Minutes
With the InstaPlay Recorder, you can easily create web and API load tests in minutes. No coding is required, even with the most complex transactions. No matter your skill level or experience load testing - if you know how to use your web app, you can load test with LoadNinja.
Get Accurate Results
Your end users use real browsers. So you should test on real browsers to get the most accurate results. LoadNinja does not deliver an approximation – it uses real browsers to provide the most realistic representation of load on the infrastructure. No maintaining or setting up load emulators.
No More Wasted Time
Manual correlation can be complicated and very time-consuming. Even small changes to an application can mean re-recording and re-correlating your test. Let your browsers handle the load and create complex performance tests without complex correlation.
Easily Identify Bottlenecks
Diagnose performance issues in your web apps and APIs in real time. Get actionable data in the form of browser-based navigation timings that developers and performance testers are used to. Accurate browser-based metrics reflect true end user experience – so you can quickly isolate issues.
Automate Load Tests & Integrate Into Any CI/CD Pipeline
Incorporate continuous performance testing into your deployment schedule. Move rapidly without sacrificing quality or coverage by parameterizing tests, then automating them using our public REST API or custom CI/CD plugins.

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
