PyroCMS is a simple, flexible, community driven Content Management System built with the PHP framework CodeIgniter.

The CMS was originaly developed by Phil Sturgeon in 2008 for various personal and commercial freelance projects and over the coarse of a few years got to be a very useful system for quickly making simple sites. In 2009 this CMS was released open-source under the name PyroCMS, taken from Phil's handle at the time "thepyromaniac".

Since those early days PyroCMS has grown rapidly to be translated into over 16 languages, accepted code from over 65 contributors and had almost 20,000 installations since v1.0 alone. Even more recently PyroCMS has evolved into two logical branches: Community and Professional. One is free, one asks a little in return for some features only those making money from PyroCMS will require.
