Drupal is an open-source content management system renowned for its robustness, scalability, and flexibility. Originally created by Dries Buytaert in 2001, it has grown into one of the most respected CMS platforms in the world, trusted by governments, universities, and large enterprises alike. Unlike simpler website builders, Drupal is built with developers in mind, offering a highly modular architecture that allows teams to construct virtually any type of web application — from news portals and e-learning platforms to large-scale intranets and APIs.
