A Load Testing Tool for Web Applications and Mobile

StresStimulus is a load testing tool for websites, mobile and Enterprise apps. It determines the web performance and scalability of your application under the rigors of heavy traffic load. Hundreds or thousands of physical users are realistically emulated through on-premise load generators or in a cloud testing environment. At the same time, server monitoring information is collected in real-time to pinpoint application performance bottlenecks and isolate web speed issues.

StresStimulus makes website stress testing and mobile performance testing super easy thanks to its end-to-end test wizard that walks you through recording, configuring and executing tests. It also saves time on mobile app load testing due to its out-of-the-box support for native app frameworks. What sets StresStimulus apart from other performance testing tools is its support for complex websites and apps combined with its competitive pricing.
