In this article we will see difference between Locust vs Jmeter vs Gatling. Comparing Locust, JMeter, and Gatling: Choosing the Right Load Testing Tool for Your Needs.

  • Locust: “Locust is a Python-based, highly scalable, and event-driven load testing tool known for its simplicity and ability to simulate large numbers of concurrent users.”
  • JMeter: “JMeter is a widely-used Java-based performance testing tool that offers a versatile and extensible platform for load testing web applications, databases, and more.”
  • Gatling: “Gatling is a powerful, Scala-based load testing tool with a focus on asynchronous, event-driven architecture, providing high performance and real-time metrics for modern applications.”
