Run a check

Enter the domain in the Website Technology Detector. It reads public headers and homepage code to find the CMS, page builder, web server, CDN, analytics, ad pixels, chat widgets and payment tools.

Check by hand

View the page source (Ctrl+U) and search for clues: /wp-content/ means WordPress, cdn.shopify.com means Shopify, gtag or googletagmanager means Google Analytics or Tag Manager.

Useful for

Competitor research, confirming your own tracking is installed, scoping website work before quoting, and spotting outdated software (an exposed WordPress version is a security risk).

Limits

Tools that load later through JavaScript or run only on the server may not be visible.

How do I know if a site uses WordPress?
