What is Drupal Licensing?

Drupal and all contributed files hosted on Drupal.org are licensed under the GNU General Public License (GPL), version 2 or later. That means you are free to download, reuse, modify, and distribute any files that are part of a project on Drupal.org under the terms of GPL version 2 or 3. You can also run the core software in combination with any code with any license that is compatible with version 2 or 3.

Drupal contributors should follow these guidelines:

  • All files (PHP, JavaScript, images, Flash, etc.) that are part of a project on Drupal.org have to be under GPL version 2 or later.
  • All Drupal contributors retain copyright on their code, but agree to release it under the same license as Drupal.
  • Drupal modules and themes are a derivative work of Drupal. If you distribute them, you must do so under the terms of GPL version 2 or later.
  • All content on Drupal.org itself is copyrighted by its original contributors, and is licensed under the Creative Commons Attribution-ShareAlike license 2.0.
  • Sample code on Drupal.org is also available under GPL version 2 or later.
