Pylot is a free open source tool for testing performance and scalability of web services. It runs HTTP load tests, which are useful for capacity planning, benchmarking, analysis, and system tuning.

Pylot generates concurrent load (HTTP Requests), verifies server responses, and produces reports with metrics. Tests suites are executed and monitored from a GUI or shell/console.

Platforms:

Console and Blocking Mode

Console and Blocking modes run on all platforms where Python 2.5+ can be installed. Tested on Windows XP, Vista, Ubuntu 8.04/8.10, Eee PC, Mac OS.

GUI Mode

Pylot GUI will run on all platforms that support Python and wxWidgets. The GUI has mostly been developed and tested on Windows, but looks decent on Linux and Mac. The application code is pure Python and uses a cross-platform toolkit.
