Paste a full website URL (or just a domain) and click Detect CMS. We fetch the public homepage and look for fingerprints in HTML, headers, and common asset paths.

Supported signals include WordPress, Drupal, Joomla, Shopify, Squarespace, Wix, Webflow, Ghost, and ProcessWire. Results are best-effort — custom or heavily cached sites may show as unknown.

For WordPress sites we also surface theme and plugin slugs when they appear in page assets. We do not scan for vulnerabilities.

Free use is limited to 100 lookups per day.
