Paste the page source of any website (or its response headers) and this checker tells you which builder or CMS it most likely runs on, such as WordPress, Shopify, Wix, Squarespace or Webflow, plus the theme name where the source reveals it and any analytics or tag managers. Every result shows the exact lines that matched, so you can judge it yourself. Browsers do not let one website read another, so you paste the source rather than a URL. Everything runs in your browser. Nothing you type or paste is sent to We.Inc or anyone else.
Most platforms leave signatures they cannot easily remove. WordPress serves files from /wp-content/ and /wp-includes/. Shopify loads assets from cdn.shopify.com and prints a Shopify object. Wix loads from static.parastorage.com and wixstatic.com. Squarespace uses static1.squarespace.com. Webflow adds data-wf-page and data-wf-site attributes to the html tag. Many platforms also add a <meta name="generator"> tag naming themselves.
Headers help too: some platforms send an X-Powered-By, X-Shopify-Stage, X-Wix-Request-Id or Server header that names them. Paste headers alongside the source when you can.
A platform link in the source is not always the platform the site is built on. A blog built on WordPress can embed a Shopify buy button, and any site can link to a Wix-hosted image. That is why the checker counts independent signals and shows them all, and why several platforms can appear with different confidence.
Sites published with We.Inc load a small analytics script from my.we.inc and are often served on a .we.inc address, so the checker reports those as We.Inc. Sites on a custom domain that removed the script will not show as We.Inc.
Browsers block a web page from reading another site's content (a security rule called CORS), and we do not run a server that fetches sites for you. Pasting the page source gives the checker exactly what your browser received, and nothing leaves your device.
It only reports what it finds in what you paste. A result marked High has several independent fingerprints, such as a generator tag plus the platform's own file host. Low means a single weaker signal. Every match is listed so you can check it.
Often. WordPress loads theme and plugin files from /wp-content/themes/<name>/ and /wp-content/plugins/<name>/, so those folder names show in the source. Caching and optimisation plugins sometimes combine files and hide them.
Usually. Shopify stores print a Shopify.theme object in the page with the theme's name. The checker reads the name from it. Stores can rename themes, so the name may be the owner's own label.
