JMeter vs Loadrunner: Which One is Better for Performance Testing?

▪️Apache JMeter

Apache JMeter is one of the most used performance testing tools for developers. It is available in an open-source format, which makes it highly accessible to software businesses of all sizes.

What makes JMeter unique is that it’s extremely versatile despite being open-source. Moreover, Loadium with JMeter offers software testers the opportunity to test their applications for both dynamic and static resources, such as queries, servers, logs, scripts, and files. Similarly, testers can also inspect applications with heavy load applications and evaluate their robustness and performance against varying load types.

Lastly, Loadium is also highly extensible and therefore, compatible with a number of third-party integrations and plug-ins. These plug-ins and third-party tools provide you additional software testing features.

HP Loadrunner (now Micro-Focus Loadrunner) is a software performance testing tool that detects and prevents performance issues in web applications. It specializes in detecting bottlenecks before the application enters the implementation or the deployment phase.

Loadrunner is not open source, and is owned by the technology giant Hewlett Packard. Therefore, the code of the application is not available to users. So, if you need a feature, you need to wait for a development roadmap.
