Xceptance LoadTest - Open-Source Load and Performance Testing Tool

An open-source load and performance testing tool allowing you to simulate hundreds or thousands of concurrent users to test the performance and scalability of web applications under heavy load.

What is XLT - Xceptance LoadTest?

XLT - Xceptance LoadTest is an open source load and performance testing tool developed by Xceptance Software Technologies. It is designed to help test the performance, scalability and robustness of web applications, web services and websites under heavy user load.

With XLT, you can simulate hundreds or thousands of concurrent users (virtual users) to generate realistic workload on the system under test. This helps identify performance bottlenecks, database issues, memory leaks, threading issues and other problems that may occur under heavy load.

Some key features of XLT include:

  • Record and replay scripts with the XLT Chrome Extension
  • Dynamic data simulation using data pools
  • Advanced correlation of dynamic session data
  • Scheduling and executing distributed load tests
  • Real-time reporting and metrics during test execution
  • Visual analysis of results using graphs and tables

XLT runs as a Java application and can be installed on Windows, Linux and macOS systems. It uses popular open source technologies like JMeter, Elasticsearch and Kibana under the hood. XLT offers broad technology support to test APIs, web UIs, mobile apps, databases and more.

With its open yet powerful architecture, XLT provides capabilities comparable to commercial enterprise-grade solutions at zero cost. It is well-suited for developers and testers in agile teams who want flexibility without the overhead of large testing frameworks.
