Drupal is an open-source content management system written in PHP, widely adopted by government agencies, universities, large enterprises, and media organizations that require a highly customizable and security-conscious publishing platform. The AIWebsiteDetector.com engine identifies Drupal installations through a combination of seven distinct technical signals, including two JavaScript file patterns, two HTML structural patterns, two characteristic HTTP response headers, and one meta tag pattern embedded in page markup. Common detection indicators include Drupal-specific generator meta tags, inline HTML attributes such as data attributes injected by the CMS core, HTTP headers like the `X-Generator` or `X-Drupal-Cache` response fields, and script paths referencing Drupal's module or core directory structure. These layered signals allow the detector to distinguish Drupal from other PHP-based CMS platforms with high confidence, even when administrators have partially obscured the installation through security hardening measures. Drupal is self-hosted software available at no licensing cost from drupal.org, though its presence on high-traffic government and institutional domains makes it one of the more consistently detectable enterprise CMS platforms in the wild, owing to the persistence of its core-generated markup across versions.
