Enter a site address to see whether it runs on WordPress, with the version and theme when the page shows them. Free, no signup.
A free checker for whether a website is built with WordPress. Enter a URL and it reads the page's HTML for WordPress paths (wp-content, wp-includes, wp-json) and the generator tag, and shows the evidence, plus the version and theme folder when visible. No signup, no email.
WordPress leaves recognisable traces in the HTML it produces: asset files under /wp-content/ and /wp-includes/, a REST API link to /wp-json/, and often a generator meta tag with the version. The tool matches only those WordPress-specific signs, so a hit is reliable.
For the full stack of a site, including analytics, frameworks and hosting clues, use the Technology Detector.
Enter its address above. The tool looks for WordPress paths, such as wp-content and wp-json, and the WordPress generator tag, and shows the snippet it found. By hand, view the page source and search for wp-content.
When the page loads files from /wp-content/themes/, the folder name is the theme's name, and the tool shows it. A child theme or a custom theme will show its own folder name.
Some sites remove the generator tag, rename the wp-content path or serve everything through a CDN. Not detected means the signs are hidden, not that WordPress is absent.
