  • Run a sequence of activities in one or more parallel sessions.

  • Can be used for testing, benchmarking, load testing, or to generate test data.

  • The most common use case is to run a test script with HTTP commands against a web server, simulating a bunch of parallel user sessions.

  • A monitor GUI is available to view live progress of running sesssions.

  • Comes with prebuilt activities for HTTP-request and more, but can be extended by custom activity-plugins.

  • This is a command line tool that runs on Linux, macOS, and Windows…

  • … and a library for use in custom Python projects.
