Performance testing is the best way to establish the speed, scalability & reliability of any app or software solution under extreme conditions. It is typically used to test the performance of any product before it is launched in the market. Software QA companies use several performance testing tools to validate the different aspects of their web and mobile applications, including open-source & licensed tools.

Testing helps meet customer expectations and secure the investor’s fund in case of product breakdown. Plus, with increasing competition in the digital landscape, the need to create a competitive edge makes testing all the more crucial for enterprises. Here are the top 7 performance testing platforms that software QA companies highly prefer, along with their key features:


This brilliant tool was explicitly launched for performing Apache JMeter-based load tests in the cloud. It is designed to scale testing to several sizes. It is compatible with various open-source platforms and plugins apart from JMeter.
