Drupal (/ˈdruːpəl/) is a free and open-source web content management system (CMS) written in PHP and distributed under the GNU General Public License. Drupal provides an open-source back-end framework for at least 14% of the top 10,000 websites worldwide and 1.2% of the top 10 million websites—ranging from personal blogs to corporate, political, and government sites. Systems also use Drupal for knowledge management and for business collaboration. As of March 2022, the Drupal community had more than 1.39 million members, including 124,000 users actively contributing, resulting in more than 48,300 free modules that extend and customize Drupal functionality, over 3,000 free themes that change the look and feel of Drupal, and at least 1,400 free distributions that allow users to quickly and easily set up a complex, use-specific Drupal in fewer steps.
