Paste a website address to see which WordPress plugins load on that page, with a link to each one in the WordPress.org directory when it’s listed there. You also get the theme and the WordPress version.
How plugin detection works
Each WordPress plugin lives in its own folder under /wp-content/plugins/. When a plugin adds a stylesheet, a script or an image to a page, the file’s address includes that folder name. The detector collects every plugin folder that appears in the page’s source.
It then looks each folder up in the WordPress.org plugin directory. When there’s a match, you get the plugin’s real name and a link. When there isn’t, the plugin is premium, sold elsewhere, or custom-built, and the list says so.
What no plugin detector can see
A plugin only shows up if it sends something to the visitor’s browser. Many don’t:
- Background plugins: security, backups, redirects, caching settings, most SEO settings and admin tools work on the server only.
- Plugins that load on some pages only: a contact form plugin may load on the contact page and nowhere else, a store plugin on the shop pages. Scan the page where the feature appears.
- Optimized sites: performance plugins can merge many files into one, which hides the original plugin folders.
So the list is what the page reveals, not the site’s full plugin list. Any tool that claims the full list from the outside is guessing.
Find plugins by hand
- View the page source: Ctrl+U on Windows, Cmd+Option+U on a Mac.
- Search for
wp-content/plugins/. - The word after
/plugins/is the plugin’s folder. Search it on WordPress.org to find the plugin.
Looking for the theme? The WordPress theme detector reads the theme’s name, version, author and parent theme.
Questions
Why is a plugin I know the site uses missing?
It doesn’t load any file on the page you scanned. Background plugins never do, and some plugins load only on specific pages. Scan the page where the plugin’s feature appears.
Does it show plugin versions?
No. Plugins don’t publish their version in a consistent place on the page, and a guessed version is worse than none.
What does “not on WordPress.org” mean?
The plugin’s folder name has no match in the WordPress.org plugin directory. It’s usually a premium plugin sold on its own site or a marketplace, or code written for that site.
Is the plugin detector free?
Yes, with no signup. If you scan a lot of sites in a short time, it asks you to wait before the next scan.
