What Our Customers Are Saying

"BlazeMeter was our indispensable ally as our team evolved from focusing primarily on B2B application testing to including B2C apps and more frequent build and test cycles."

Alex Emmermann
VP Engineering, ClearLeap

“All of our performance testing was handled by a third party. It was expensive and we had no control. Now, all of the Mattel sites are using BlazeMeter to validate performance. They love the flexibility, fluid interface and friendly staff from BlazeMeter. There’s no turning back."

Nitin Jindal
Performance Engineer, Mattel

“People today have really high expectations on how a website performs. Performance is everything. If we can’t serve pages quickly, our customers will go somewhere else. Load testing with BlazeMeter enabled us to meet those expectations."

Craig Lefkowitz
Director of Infrastructure Systems,

"We gained more control over our development speeds, scripts and customer response times in our Continuous Integration environment thanks to BlazeMeter."

Norm Warren
Developer, Ancestry

"Taurus by BlazeMeter is by far the easiest way to run a load test. It'll wrap around JMeter or whatever load testing tool you prefer (installing it for you in the background)."
