History of CodeIgniter


EllisLab made CodeIgniter public for the first time on February 28, 2006. It was originally nothing more than a set of refactored general-purpose classes copied from the ExpressionEngine (EllisLab’s flagship CMS) codebase with the all application-specific code stripped out.


Though the field is now crowded with PHP frameworks, CodeIgniter was one of the first to gain real traction.


EllisLab started seeking a new owner for CodeIgniter in July, 2013, claiming to lack the resources to properly maintain the framework. The handoff of ownership from EllisLab to the British Columbia Institute of Technology was publicly announced on October 6, 2014.
