Enter any website address in the box above and the WordPress Theme Detector looks for the theme the site uses, then reads the theme’s own details file to show its name, version and author. It is free, needs no sign-up, and usually takes a few seconds.

How to find out what WordPress theme a site uses

1. Enter the address

   Type a domain such as example.com, or paste any page from the site.

2. Click Detect Theme

   The tool finds the theme folder in the page code and reads its details.

3. Read the result

   You get the theme name, version, author and, for child themes, the parent theme.

What the theme detector shows

The tool reports the theme only. It does not list plugins, and it cannot tell you whether a theme is free or premium. To find that out, search for the theme name or follow the theme website link in the result.

How WordPress theme detection works

Every WordPress theme lives in its own folder under /wp-content/themes/, and the pages of a site load files from it. The tool looks through the page code for that folder, then requests the theme’s style.css file. The top of that file is a header where the theme states its name, author, version and parent theme.

How to find a WordPress theme manually

You can do the same thing by hand in any browser:

1. View the source

   Right-click the page and choose View page source.

2. Search the code

   Press Ctrl+F (or Cmd+F) and search for wp-content/themes/.

3. Note the folder

   The name right after it is the theme folder, for example /themes/astra/.

4. Open style.css

   Visit site.com/wp-content/themes/astra/style.css to read the theme header.

Child themes explained

A child theme is a small theme that builds on a parent theme. Developers use it to customise a site without losing their changes when the parent theme updates. When a site uses one, its pages load files from both folders. The detector reports the most-used folder first and shows the parent theme when the child theme declares one.

When the theme detector cannot find the theme

• The site is not WordPress. Run the CMS Detector to see what it uses instead.
• The site is headless. A headless WordPress site shows a separate front end that does not load a WordPress theme.
• The theme is custom-built or renamed. You may only see a custom folder name that matches no public theme.
• Paths are rewritten or hidden. Some optimisation and security setups change or conceal the theme folder.
• The site blocks automated checks. A firewall can stop the tool from reading the page at all.

Why check a site’s WordPress theme?

• Before buying a theme. See how it looks and performs on a real, live site.
• Finding a design you like. Identify the theme behind a layout you admire.
• Researching competitors or prospects. Learn how the sites in your market are built.
• Briefing a developer. Tell them exactly which theme or style you have in mind.
• Troubleshooting. Check which theme and version a site runs before you debug an issue.

What is a WordPress theme?

A WordPress theme is a collection of templates and styles that controls how a site looks: layout, colours, fonts and page structure. It changes the design without touching your content, so you can switch themes and keep your pages and posts. Themes range from free options to premium, feature-rich designs.
