Definition
Drupal is a free, open-source content management system (CMS) framework built on PHP, known for its flexibility, robust access-control system, and suitability for large, complex websites with structured content.
Overview
Drupal is one of the longest-standing open-source CMS platforms, often chosen for large institutional, government, media, and enterprise websites that need to manage complex, structured content and fine-grained permissions across many users and roles. Rather than being just a blogging tool, Drupal is better described as a content management framework: its core provides content types, taxonomy, user roles and permissions, and a module system, while sites are typically built by combining and configuring modules rather than writing an application from scratch. Drupal's architecture centers on "nodes" (pieces of content), custom content types with configurable fields, and a powerful views system for querying and displaying content in different ways without custom code. Its permissions and workflow system is notably granular, which is part of why it's favored for sites with many contributors and complex editorial or governance requirements, such as government agencies and universities. Drupal can also operate in a "headless" or "decoupled" mode, exposing content via REST or JSON:API so a separate frontend — built with something like React or Next.js — can consume it. Compared to WordPress, Drupal generally has a steeper learning curve but offers more structural flexibility and stronger built-in access control, making it a common choice for large organizations rather than small businesses or individual bloggers, who more often gravitate toward WordPress or hosted builders like Squarespace.
