LoadUI

LoadUI is a load testing software, targeted mainly at web services. LoadUI runs on Windows, Linux and Mac OS. LoadUI allows users to test the speed and scalability of APIs, preview API performance behaviors before releasing to production environments.

History
There was an open source version, but it was discontinued in July 2014. In 2015 LoadUI became a part of ReadyAPI under the name LoadUI Pro. Most of the user interface as well as all JavaFX eye-candies were removed. Use interface was simplified and divided into five visual parts. Old projects could now be imported from the file with some limitations.

It has been superseded by LoadUI Pro in the ReadyAPI platform.
