How can I tell what website builder a site uses?

Each builder leaves fingerprints in the page code: Webflow adds data-wf-site to the page, Framer serves images from framerusercontent.com, Shopify loads files from cdn.shopify.com, and WordPress keeps files in /wp-content/. Paste the address into the checker and it looks for those signs for you.

Which platforms can the checker recognise?

Webflow, Framer, Shopify, WordPress, Wix, Squarespace, HubSpot CMS, Ghost, BigCommerce, Carrd, Duda, and custom sites built with Next.js. We list the signs we found so you can see why we reached each answer.

Why does it say it couldn't match a builder?

The site may be hand-coded, built on a platform we don't recognise yet, or hiding its markers. Some sites also block automated visits, in which case we can't read the page.

Can it tell which template a site uses?

For Shopify stores it can name the theme. Webflow and Framer sites don't publish the template they started from, so we can only match them when the address is a template's own demo site.

Yes, with no sign-up and no limit on how many sites you check.

How the Checker Works

We load the page the same way a browser does and look for the signs each platform leaves behind: meta tags, file locations, page attributes and server headers. No guessing from the design. If we find signs of more than one platform, we list them all, with the strongest match first.

You also get the site's fonts, its main colors and its page title and description, which helps when you're planning a similar site of your own.
