Can it detect active WordPress plugins?

Yes. It scans asset URLs (wp-content/plugins/) and DOM markers to identify popular plugins for page building (Elementor, Gutenberg), SEO (Yoast, Rank Math), e-commerce (WooCommerce), and analytics.

Why does it say 'Custom Theme' on some websites?

If an agency or enterprise developer custom-coded a proprietary theme or renamed the style.css metadata, the detector identifies it as a custom private build.

Does this work on Shopify, Wix, or Webflow sites?

No. This tool is specifically designed for WordPress sites (both WordPress.org self-hosted and WordPress.com). If the site is built on another CMS, the detector will indicate that WordPress was not found.

How can I check a website’s theme without installing any software?

Just paste the site URL into the WordPress Theme Detector and click "Analyze". The tool runs entirely in your browser, reads the public CSS and JavaScript files, and returns the theme name, version, parent/child relationship and active plugins in seconds—no plugins, extensions, or downloads needed.

What’s the best way to detect the theme of a WordPress site that uses a custom child theme?

The detector first looks for the child‑theme stylesheet header. If found, it shows the child‑theme name and then scans the parent‑theme’s style.css to reveal the underlying framework. This two‑step lookup works for any custom or commercial child theme, giving you both the child and its parent details.
