Drupal

Drupal is a PHP content management framework built on Symfony that gives developers precise control over content types, fields, and permissions. It provides content modelling, views and blocks, a RESTful JSON:API, multilingual support, and a large catalogue of contributed modules for search, SEO, and editorial workflow.

Organisations use it for corporate sites, intranets, and multi-site publishing where structured content and access rules matter more than a simple page builder.

Running it yourself keeps the whole stack inside your perimeter, so code and database are backed up with the standard tools you already use and there is no per-seat pricing.
