LoadUI
LoadUI is a load testing software, targeted mainly at web services. There was an open source version, but was discontinued in July 2014. In 2015 LoadUI became a part of Ready!API under the name LoadUI NG. Most of the user interface as well as all JavaFX eye-candies was 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It has been superseded by LoadUI NG Pro in the Ready! API platform.
