Open-Source Load Testing Tools

Overview

Let’s go through some open-source load testing tools in this tutorial. A load testing tool is a software or framework designed to simulate high user loads on the SUT(System Under Test), such as a website, web application, API, etc in order to measure its performance under expected load as well as under unexpected load conditions( for example on peak load ).

Open-Source Load Testing Tools

Some of the popular load test tools are as follows:

  • Apache JMeter
  • K6

Apache JMeter

Apache JMeter is a Java-based tool that can load test various applications and protocols, such as HTTP, SOAP, FTP, JDBC, and JMS. It has a graphical user interface and a command-line mode. It supports scripting and extensibility through plugins

More information on the JMeter:

K6

k6 is an open-source load testing tool that makes performance testing easy and productive for software teams. k6 is free, developer-centric, and extensible. k6 is developed by Grafana Labs.

Using the K6 tool, we can test the reliability and performance of the systems and catch performance regressions and problems earlier. k6 will help to build resilient and performant applications that scale.
