What the WordPress theme detector finds
Eight checks, all from the outside. You don't install anything or give us a login.
WordPress plugin weight
Measures how much each plugin adds to the page, since heavy plugins load on every page.
Duplicate caching plugins
Checks only one caching plugin is active, since two can break scripts and serve stale pages.
Duplicate SEO plugins
Checks only one SEO plugin is active, so Google does not get duplicate or conflicting tags.
Schema from multiple plugins
Checks only one plugin outputs structured data, since conflicting blocks make Google withhold rich results.
Plugins closed on wordpress.org
Flags detected plugins that wordpress.org has closed, often because of a security issue.
Abandoned plugins
Flags detected plugins with no update in over 2 years, which no longer get security fixes.
Technology stack
Lists the CMS, framework, CDN and analytics behind the page, so you know which settings to use.
CMS version
Compares the CMS version your page reveals with the latest release, since old versions have known holes.

How the WordPress theme and plugin detector works
Read the page
We fetch your page and list every file under /wp-content/plugins/, plus the comments and headers SEO and caching plugins leave.
Measure in Chrome
The page loads in a real browser. Every request is matched to its plugin, so each plugin gets its own kilobytes, requests and time.
Check wordpress.org
Each plugin is looked up in the wordpress.org directory for its latest version, last update and whether it was closed.
We only see what a page loads for visitors. Backup, security and admin-only plugins load nothing on the front end, so they don't appear.
WordPress theme and plugin questions
How do I find out what WordPress theme a site is using?
Enter the page above. The detector reads the theme from the files the page loads, /wp-content/themes/ followed by the theme folder, with its version when the file URL carries one. The folder name is usually the theme name, such as astra or hello-elementor. When a site runs a child theme, both folders load, so you see the child theme and the parent it is built on.
What is a WordPress theme?
The set of templates and styles that decides how a WordPress site looks: layout, fonts, colours, headers and footers. You can switch themes without losing your posts and pages. Many themes are free in the wordpress.org directory; premium ones are sold by their developers. A page builder such as Elementor or Divi often does the layout on top of a light theme.
How can I see which plugins a WordPress site uses?
Enter the address above. Every file the page loads from /wp-content/plugins/ is matched to its plugin, together with the comments and headers that SEO and caching plugins leave. We never guess plugin names or probe for them, so the list shows only what the page reveals. Each plugin is looked up in the wordpress.org directory for its latest version and status.
Can it show how much each plugin slows my page?
Yes. The checker loads the page in a real browser and assigns every request to its plugin, so each gets its own kilobytes, request count and time. Page builders, sliders, social feeds and chat widgets usually top the list. Start with the heaviest plugin that page does not need, then run the check again to see the difference.
Why is a plugin I use missing?
A plugin appears only when it loads something on the page you checked. Plugins that work in the admin area, such as backups, security or redirects, or only on other pages, such as a form on the contact page, load nothing here. Check the page where the plugin is used to see it and its cost.
What do "closed" and "abandoned" mean?
Closed means wordpress.org removed the plugin from its directory, usually for an unfixed security issue or a guideline violation; the reason is shown, and you should replace the plugin. Abandoned means it has not been updated in over 2 years, so security fixes and compatibility with new WordPress versions are unlikely. Plan a replacement for both.
Does it detect premium plugins and themes?
Yes, when they load files on the page. Premium plugins and themes are not in the wordpress.org directory, so they have no update date or closed status here. Check them in your account with the developer who sells them, and keep their licence active so you receive security updates.
