About Apache JMeter

Apache JMeter is a robust, open-source Java application engineered for load testing functional behavior and measuring system performance across diverse environments. It serves software developers, QA engineers, and DevOps professionals by simulating heavy traffic loads on servers, networks, or objects to analyze overall performance under different conditions. Supporting a wide array of protocols like HTTP, REST, and JDBC, its primary differentiator is its high extensibility and platform independence, allowing teams to conduct complex, scalable performance testing without the overhead of expensive proprietary software solutions.
