Remove X-Generator is a common requirement for Drupal sites. The Mix module can deal with this and many other common situations.

By checking the "Remove X-Generator" checkbox in /admin/config/mix, the following items can easily be removed:

• The "X-Generator" in the HTTP header
• The meta tag <meta name="Generator" content="Drupal 10 (https://www.drupal.org)"> from the page source code

Without coding

Remove X-Generator is a common requirement for Drupal sites. The Mix module can deal with this and many other common situations without coding.

By checking the "Remove X-Generator" checkbox in /admin/config/mix, the following items can easily be removed:

• The meta tag <meta name="Generator" content="Drupal 10 (https://www.drupal.org)"> from the page source code.
• The "X-Generator" in the HTTP header.

Coding

These only take a few lines of code.

To remove the <meta name="Generator" content="Drupal 10 (https://www.drupal.org)">, implement this in [yourmodule].module file.

@see https://git.drupalcode.org/project/mix/-/blob/1.x/mix.module#L96

/**
 * Implements hook_page_attachments_alter().
 */
function HOOK_page_attachments_alter(array &$attachments) {
  foreach ($attachments['#attached']['html_head'] as $key => $attachment) {
    if ($attachment[1] == 'system_meta_generator') {
      unset($attachments['#attached']['html_head'][$key]);
    }
  }
}

To remove the "X-Generator" HTTP header, you can implement an EventSubscriber.

@see https://git.drupalcode.org/project/mix/-/blob/1.x/src/EventSubscriber/MixSubscriber.php#L113

  public function onKernelResponse(ResponseEvent $event) {
    $response = $event->getResponse();
    $response->headers->remove('X-Generator');
  }
