Why CodeIgniter?

Framework with a small footprint

CodeIgniter 3 has a 2MB download, including the user guide.

Exceptional performance

CodeIgniter consistently outperforms most of its competitors.

Simple solutions over complexity

CodeIgniter encourages MVC, but does not force it on you.

Strong Security

We take security seriously, with built-in protection against CSRF and XSS attacks.

Clear documentation

The CodeIgniter User Guide comes with the download. It contains an introduction, tutorial, a number of “how to” guides, and then reference documentation for the components that make up the framework.

Nearly zero configuration

Much of the CodeIgniter configuration is done by convention, for instance putting models in a “models” folder. There are still a number of configuration options available, through scripts in the “config” folder.
