ProcessWire is a free and open-source, flexible and powerful content management system (CMS) and content management framework (CMF) written in PHP5. ProcessWire was chosen as CMS Critic’s best free CMS back in 2012. Just like the most CMSs, the installation and configuration is quite simple and you don’t have to be a web developer or administrator to install ProcessWire.
