What CMS is this website using? Paste any URL to check its CMS — WordPress, Wix, Shopify, Squarespace, Drupal and more — plus the full tech stack: frameworks, analytics, hosting and server.
To check what CMS a website is using, paste its URL above. The checker reads the site’s public homepage and fingerprints its HTML, scripts and headers, then reports the CMS it detected — WordPress, Wix, Shopify, Squarespace, Joomla, Drupal, Webflow and others — together with the framework, analytics, hosting, CDN and web server behind it.
A plain CMS check answers one question: which content management system powers the site. This CMS detector goes further and lists every technology it can fingerprint, so you also see the page builder, e-commerce platform, analytics and CDN. If the CMS comes back as “custom”, the stack list usually still reveals how the site was built.
WordPress (including WooCommerce, Elementor and Divi), Wix, Squarespace, Shopify, Webflow, Joomla, Drupal, GoDaddy Website Builder, Weebly, Duda, HubSpot CMS, Ghost, Magento, PrestaShop, BigCommerce and many more. The version number is reported whenever the site exposes it.
Yes. You can view the page source and look for signatures like /wp-content/ (WordPress) or static.wixstatic.com (Wix), or check the generator meta tag. We walk through the four manual methods in how to tell what CMS a website is using. The checker above just does all of them at once.
For a web design agency, an outdated WordPress install or a templated Wix site is a clear signal the business is a strong prospect for a redesign. The framework, analytics and hosting reveal how technical (and how invested) they are. LeadWebia detects the CMS and tech automatically on every lead it finds, so agencies can filter prospects by stack at scale. And if a business has no website at all, that is an even stronger lead.
Paste the site URL above and press "Check site". The CMS Checker fingerprints the page and tells you which CMS it runs on — WordPress, Wix, Shopify, Squarespace, Joomla, Drupal, Webflow and more — along with the version when the site exposes it.
Enter the domain (for example example.com) and run the check. You get the CMS, the web server, whether it uses HTTPS, and the full technology stack. No signup and no access to the site is needed — only its public homepage is read.
We fetch the public homepage and fingerprint its HTML, scripts, headers and signatures, the same technique tools like Wappalyzer and BuiltWith use. No login or access to the site is required.
Beyond the CMS it detects the wider stack: JavaScript frameworks, e-commerce platforms, analytics, hosting and CDN, web server, security technologies and fonts, with versions where available.
Some sites are custom-built, hide their stack, or block automated requests. "Unknown" means no common off-the-shelf CMS was detected, but the technology list below may still reveal the framework and stack.
Run the check above: the first row shows the CMS by name (for example WordPress 6.5 or Wix). If it says "Custom / not detected", the site is hand-coded or hides its stack, and the technology list shows what it runs on instead.
If you are not sure what your own site is built on, enter your domain above. It is also visible in your admin login URL: /wp-admin means WordPress, and Wix, Squarespace and Shopify sites log in through their own dashboards.
Yes. View the page source and look for signatures such as /wp-content/ (WordPress), wixstatic.com (Wix), cdn.shopify.com (Shopify) or a generator meta tag. The checker automates all of these signals in one request.
