What this tool does
Enter the address of a WordPress site. The tool loads the page, looks for assets under /wp-content/themes/, and then reads that theme’s public style.css. It reports the theme’s name, version and author where the header is available, notes if it appears to be a child of another theme, and lists some plugins whose assets show up in the page.
How it finds the theme
Most WordPress themes load their stylesheet from /wp-content/themes/theme-name/style.css. The folder name gives the theme slug. The comment header at the top of that file contains Theme Name, Author, Version, and, for child themes, Template, the parent theme’s folder.
When detection fails
- Custom or renamed theme folders. Developers sometimes rename the folder, so you see the folder name, not the product name.
- Security or caching plugins that hide or rewrite paths, or combine assets into a single file, can remove the clues.
- Sites behind bot protection may refuse this server’s request, and the tool will tell you the page couldn’t be retrieved.
- Headless WordPress. If the front end isn’t rendered by WordPress, there is nothing to detect.
- Page builder sites often show the builder’s assets more clearly than the theme.
The plugin list covers only plugins that load a visible asset on that page. Plugins that run entirely on the server are invisible.
Practical use
Checking which theme a site you admire is built on, confirming the theme of a client site, or telling whether a site is on a child theme before you edit it. Knowing a theme isn’t the same as having a licence for it, so buy or download themes from their authors.
Results are cached for 30 minutes, with up to 12 checks a minute. For general software detection use the Technology Detector.
Why does it show a folder name instead of the theme’s real name?
The theme’s style.css header couldn’t be read, or the developer renamed the folder.
Why does it say the site isn’t WordPress?
The theme assets weren’t found. The site may use another CMS, hide its paths, or be headless.
Does it list all the plugins on the site?
No. Only plugins that load a visible file on the page it checked.
Can it tell me the theme’s price or where to buy it?
No. Search for the theme name from its author’s site.
How does it find the theme name?
It looks for assets under /wp-content/themes/ and reads that theme’s public style.css header for the name, version, author and parent theme.
