About WP Theme Checker

WP Theme Checker is a free tool that identifies the theme, plugins, and hosting provider behind any WordPress site. Paste a URL, get an answer.

How it works

We fetch the homepage of the URL you submit and run a multi-source detection pass:

• Theme — detected from /wp-content/themes/ asset paths in the HTML, then enriched by reading the theme's style.css header for the canonical name, version, author, and parent-theme (if it's a child theme).
• Plugins — five detection vectors combined: asset paths in the HTML, REST API namespaces at /wp-json/, ~100 hand-curated HTML signatures (JS globals, class prefixes, sitemap stylesheet comments), and a fallback probe against the top 100 popular plugins on wordpress.org. Each plugin is labeled with how it was detected so you can see the confidence.
• Hosting — four signal layers: HTTP response headers (the most authoritative when the host doesn't mask it), HTML footer attribution, subdomain CNAME probing of cpanel/webmail/mail/ftp subdomains (which often bypass CDNs and reveal the underlying host), and DNS NS lookups via DoH.
