CodeIgniter was originally developed by EllisLab. The framework was written for performance in the real world, with many of the original class libraries, helpers, and subsystems borrowed from the codebase of ExpressionEngine. It was, for years, developed and maintained by EllisLab, the ExpressionEngine Development Team and a group of community members called the Reactor Team.

In 2014, CodeIgniter was acquired by the British Columbia Institute of Technology and was then officially announced as a community-maintained project.

In 2019, the CodeIgniter Foundation was formed to provide a perpetual managing group separate from any other entity to help ensure the framework's future.
