CMS Detector
Detect the CMS, framework or platform powering any website.
About the CMS Detector
The CMS Detector fetches a website and analyzes response headers, HTML markup, meta tags, script URLs and cookies to identify the CMS or website builder powering the site — WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Ghost, Contentful, Sanity, and dozens more. It also identifies common e-commerce platforms, marketing stacks, analytics tools and CDNs.
Sales teams use CMS detection for outbound prospecting (find every WordPress site in a target list). Agency devs use it before quoting a migration (knowing the source CMS shapes the estimate). Security researchers use it during recon (WordPress plugin vulnerabilities are common). Competitor analysts use it to understand a rival's tech stack.
Detection is heuristic — sites can hide their CMS by removing telltale headers, obfuscating asset paths, or serving pages through a reverse proxy. Confidence in the detection is highest when multiple signals agree (headers + markup + script URLs all pointing to the same platform).
