CMS & Technology Detector
WordPress, Shopify, Wix and the stack behind a site.
How it works
What CMS or platform is this website built on?
Paste a domain and we fetch the live homepage from our server, then look for fingerprints in the HTML and response headers: /wp-content/ paths and wp-json links for WordPress, cdn.shopify.com for Shopify, X-Wix-Request-Id for Wix, static1.squarespace.com, __NEXT_DATA__ for Next.js, generator meta tags for Drupal, Joomla and Ghost, plus analytics tags, CDNs and server software. Each match is shown with the evidence so you can judge it yourself.
Results appear here after you click Detect technology.
How this works
- 1
Fetch the homepage
Our server downloads the first 64 KB of the live homepage plus the full response headers, following redirects to the canonical URL.
- 2
Match fingerprints
HTML and headers are matched against 50 signatures covering CMSs, builders, e-commerce, frameworks, analytics, CDNs and web servers.
- 3
Show the evidence
Every detection is listed with the exact string or header that triggered it, so you can verify rather than trust.
Frequently asked questions
- How can I tell if a website is built with WordPress?
- View the page source and search for /wp-content/ or /wp-includes/, or check whether example.com/wp-json/ returns JSON. A generator meta tag naming WordPress is common but often removed by security plugins. This tool checks all of those automatically.
- Is this website on Shopify, Wix or Squarespace?
- Hosted builders leave strong traces: Shopify loads assets from cdn.shopify.com and returns an X-ShopId header, Wix returns X-Wix-Request-Id and loads static.wixstatic.com, Squarespace serves from static1.squarespace.com. The detector shows which of these appeared.
- Why did it find nothing on a site I know uses a CMS?
- Caching layers, security plugins and custom themes can strip generator tags and rename asset paths. Single-page apps render in the browser, so the server HTML is nearly empty. Try a blog post or product page, where platform markup is harder to hide.
- Does this tool detect the hosting company too?
- It reports CDNs and platform hosts that announce themselves in headers (Cloudflare, Vercel, Netlify, CloudFront). For the company that owns the server IP, use our Hosting Provider Lookup, which checks network registry data.
- Can a site be built with more than one of these?
- Yes, and most are. A typical result is WordPress plus WooCommerce, jQuery, Google Tag Manager, Cloudflare and LiteSpeed. The CMS is the foundation; the rest are libraries, tracking scripts and infrastructure layered on top.
