Drupal (//) is a free and open-source web content management system (CMS) written in PHP and distributed under the GNU General Public License. Drupal provides a back-end framework for at least 13% of the top 10,000 websites worldwide – ranging from personal blogs to corporate, political, and government sites. Systems also use Drupal for knowledge management and for business collaboration.

As of March 2021[update], the Drupal community comprised more than 1.39 million members, including 121,000 users actively contributing, resulting in more than 46,800 free modules that extend and customize Drupal functionality, over 2,900 free themes that change the look and feel of Drupal, and at least 1,300 free distributions that allow users to quickly and easily set up a complex, use-specific Drupal in fewer steps.
The standard release of Drupal, known as Drupal core, contains basic features common to content-management systems. These include user account registration and maintenance, menu management, RSS feeds, taxonomy, page layout customization, and system administration. The Drupal core installation can serve as a simple website, a single- or multi-user blog, an Internet forum, or a community website providing for user-generated content.
Although Drupal offers a sophisticated API for developers, basic Web-site installation and administration of the framework require no programming skills.
