CapacityTester: Open-Source Load & Performance Testing Tool

Test website capacity and performance with CapacityTester, a free and open-source load testing tool for websites and web applications.

What is CapacityTester?

CapacityTester is an open source load and performance testing tool for testing the capacity and performance of websites and web applications. It is designed to simulate a large number of concurrent users accessing a website to determine at what point the performance starts to degrade.

The tool allows users to configure different test scenarios by setting the number of virtual users, ramp-up time, test duration etc. Users can monitor a number of performance metrics like response times, throughput, errors etc. to determine how the website holds up under load.

Key features include:

  • Ability to simulate thousands of concurrent users from multiple geo locations
  • Flexible test configuration options
  • Monitoring of key web performance metrics
  • Command line and GUI modes
  • Support for testing web sites, web services, databases
  • HTML reporting of test results

CapacityTester is a useful open source solution for developers and testers to load test their web applications during development as well as for production testing. It can help identify performance bottlenecks under load and benchmark application improvements.
