The initial version of Crawljax has been developed by Ali Mesbah as part of his PhD research. Since then, several master students have worked on Crawljax in the context of their master thesis. The complete list of contributors can be found on: http://crawljax.com/about/

 

Crawljax initially started as a research project within the Software Engineering Research Group (SERG) of Delft University of Technology.

 

Although it is still largely maintained by this group, the project is open-source and used on various other places around the world.
