What's that site built with?
Enter a website and the detector checks whether it runs WordPress, then identifies the theme by reading its style.css header: the theme name, author, version, theme website and the parent theme when a child theme is used.
It also lists the plugins visible from the front end — SEO plugins like Yoast and Rank Math, page builders like Elementor, WooCommerce, caching and form plugins — using asset paths, version numbers and the site's REST API.

Frequently asked questions
Why does it say “custom or hidden theme”?
Some sites rename their theme folder or use a fully custom theme with no standard style.css header.
Can I detect every plugin?
No. Only plugins that add scripts, styles or visible markup to pages can be seen from outside.
Is this legal?
Yes. The tool only reads information every visitor's browser downloads.
