How can I find out what CMS a website is using?

Paste the website URL into ZaxisMedia's free CMS Detector and it instantly identifies whether the site runs on WordPress, Shopify, Wix, Squarespace, Webflow, Joomla, Drupal or another platform. No signup needed.

How does CMS detection work?

Every CMS leaves fingerprints: meta generator tags, distinctive asset paths (like /wp-content/ for WordPress), platform-specific scripts and response headers. The tool fetches the homepage and matches these patterns.

Which CMS platforms can it detect?

WordPress, Shopify, Wix, Squarespace, Joomla, Drupal, Ghost, Webflow and Blogger, the platforms behind the vast majority of websites.

What if no CMS is detected?

The site likely uses a custom-built platform, a headless CMS, or a heavily customized setup that hides its fingerprints. That is common for large enterprise sites.

How accurate is CMS detection?

Very accurate for the big platforms, their fingerprints are distinctive. Generator-tag matches are high confidence; asset-path matches are medium confidence and still reliable.

About the CMS Detector

Ever wondered what powers a competitor's website? The CMS Detector fetches the homepage HTML and response headers, then matches them against fingerprint signatures for WordPress, Shopify, Wix, Squarespace, Joomla, Drupal, Ghost, Webflow and Blogger.

Agencies use it for competitive research, developers use it before quoting rebuilds, and curious site owners use it to confirm what their own site runs on.

Where it helps most

Reconnaissance where the platform answer shapes what happens next.

Research rivals

Agencies studying a rival's site learn whether they face a Shopify store or a custom build before they ever talk strategy.

Quote rebuilds accurately

Developers asked to rebuild or take over a site quote accurately, since a WooCommerce store costs very differently from a Webflow one.

Sanity-check your own

Site owners run their own domain through it as a sanity check, confirming the platform they pay for is actually serving the pages.

Read the evidence

Every result shows the evidence behind the match, from meta generator tags to giveaway asset paths such as /wp-content/ exactly.

Trusting the match

How confidence works, and its honest limits.

Generator tags score high

A generator-tag match carries high confidence because few sites fake them, while an asset-path match scores medium but stays reliable.

No match is informative

When nothing matches, the site probably runs a custom platform, a headless CMS or a hardened setup, which is normal for large enterprise sites.

It is legal

Yes, it is legal: the checker only reads the public HTML and headers that any visitor's browser receives, never anything private.

CMS Detector: built for trust

Reads only the public HTML and headers any visitor's browser receives. Never probes for vulnerabilities or anything private.
