A PHP content management system and framework built on custom fields and an API developers use to model sites of any size.
ProcessWire is a content management system and a content management framework in one, built so developers model content with their own fields rather than bend a fixed schema. It gives more control over fields, templates and markup than most platforms while keeping an admin simple enough to hand a client without training.
The project has been around a long time. It started in 2003, took the ProcessWire name in 2006, and has been open source since 2010, with new versions landing on the development branch most weeks. It is also deliberately quiet, valuing quality over quantity and sustainability over growth, and it is meant to be a silent partner that is not easily identified from a site's front end.
Several traits explain how it is used in practice.
- Custom fields throughout: content structure comes from fields you define, not a template the CMS chose for you.
- An API for content: it stays consistent at any scale and is why developers stay once they try it.
- A client-facing admin: the interface is valued by the people updating content, not the ones building the site.
- Simple installation: extract the files somewhere reachable over HTTP, load the address, and the installer starts.
- Low-friction upgrades: moving between 3.x versions usually means replacing the wire directory, with documented paths from 2.x and from before 3.0.135.
- Modules: free modules sit alongside commercial Pro ones such as FormBuilder, ListerPro, ProFields and ProCache.
Support comes from the forums, a weekly newsletter and a showcase of sites built with it.
