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.

ProcessWire is built around an API with usage and naming conventions similar to the JavaScript framework jQuery.

These communities have translated ProcessWire from English into their native languages, including: Chinese, Croatian, Czech, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Portuguese, Russian, Slovak, Spanish, Swedish, Turkish, Ukrainian and Vietnamese.

The central hub of the ProcessWire communities are found in the developer support forums.

[17] In December 2014 PHP Architect published ProcessWire: Flexibility, Power, and a Generous Dose of Pure Fun.

[19] ProcessWire is built around a page content tree (as opposed to a bucket system).

As a result, this connection of the path to the internal tree hierarchy defines the architecture of ProcessWire.

ProcessWire's default web site profiles use template-files primarily for output of direct and dynamically generated HTML markup.

ProcessWire's source code is hosted on GitHub and is also distributed on Softaculous, Bitnami and Composer/Packagist.

ProcessWire runs in the AMP (Apache, MySQL or MariaDB, PHP) platform used by many hosting providers and web development environments.
