ProcessWire

ProcessWire is a free and open source content management system (CMS), content management framework (CMF) and web application framework (WAF) written in the PHP programming language. It is distributed under the Mozilla Public License 2.0. ProcessWire is built around an API with usage and naming conventions similar to the JavaScript framework jQuery. The stated goal behind the API is to provide the level of accessibility and control to pages in a website that jQuery provides to the DOM. Content is managed either via the API or the web-based admin control panel. ProcessWire is largely used for development of web sites, web applications, services, content feeds and related applications.
