Theme
The theme and its version
The theme’s name, version, author and website, read from its own style.css, which is where WordPress requires them to be declared. If the site uses a child theme, we also tell you the parent theme.

How to use the WordPress theme detector
- 01
Paste the address
Copy the URL of the site you want to analyze (the home page or any other page) and paste it above. If you leave out
https://, we add it for you. - 02
Read the result
In a few seconds you see whether the site is WordPress, which theme it uses with its version and author, the page builder and the plugins visible on that page.
- 03
Check the clues
Open “How we know” on any finding: you get the path, tag or code comment that gives it away, so you can check it yourself.
02
What the WordPress theme and plugin detector finds
Plugins
The plugins you can see
Every plugin that loads something on the page (styles, scripts or classes), with its real name and its version when it publishes it in its readme.txt or in the ?ver= of its files.
Page builder
Elementor, Divi, Bricks…
The page builder the layout is made with: Elementor, Divi, Beaver Builder, WPBakery, Bricks, Oxygen or the block editor (Gutenberg). Plus animation and scroll libraries such as GSAP or Swiper.
Other sites
If it isn’t WordPress
It tells you what the site is built with when its code gives it away: Shopify, Wix, Webflow, Squarespace, Framer, Joomla, Drupal, PrestaShop, Ghost or HubSpot, and frameworks such as Next.js, Nuxt, Astro or SvelteKit.

How to find out what WordPress theme a site uses, by hand
If you’d rather do it yourself, it takes a couple of minutes. It’s the same thing the tool does:
- Open the page source. On the site you want to analyze, press Ctrl + U (on Mac, Cmd + Option + U). A tab opens with the page’s HTML.
- Find the theme folder. Press Ctrl + F and search for
wp-content/themes/. The word right after it is the theme folder: in/wp-content/themes/Divi/style.css, the theme is Divi. - Open its style.css. Type
yoursite.com/wp-content/themes/theme-folder/style.cssinto the address bar. The first lines give the name (Theme Name), the version (Version), the author (Author) and, if it’s a child theme, the parent theme (Template). - For plugins, search for
wp-content/plugins/. Each folder that shows up is a plugin that loads something on that page. Its version is usually in the?ver=of the path or inwp-content/plugins/plugin-folder/readme.txt.
If wp-content doesn’t appear anywhere, the site may not be WordPress, or a security plugin may have changed the paths. The detector also looks at other signals, such as the generator tag, the page builder’s classes or the comments SEO plugins leave behind, and tells you what the site is built with.

Why this theme detector finds themes others miss
Most online detectors look up the folder name in their database of known themes. If the theme isn’t on their list, they answer “not found” or “custom theme”, even when it’s one of the best sellers.
This one doesn’t depend on any list: it reads the theme’s own style.css and the plugins’ readme.txt files. We tested it on a design studio’s site built with Divi: another well-known detector said it couldn’t find the theme. Here we got Divi 5.15.1, WordPress 7.1.4 and its two plugins with their versions, each finding with its clue.
We don’t ask for your email and we don’t store anything: neither the address you analyze nor the result.
The same thing, on any site you visit and without leaving it: theme, plugins, fonts, colors and SEO, in one click.

What the WordPress theme detector can’t see
Plugins with no trace
The ones that work behind the scenes
Security, backups, server caching or a form that isn’t on that page leave nothing in the HTML. No tool can see them from the outside.
Sites that hide
Renamed paths
Some security plugins rename wp-content or the theme folder. The theme may then show up under its folder name, with no version or author.
JavaScript
What loads afterwards
We read the HTML the server sends. What gets added later with JavaScript is only visible to the extension, in your browser, with the page already rendered.

This and much more, on any website
The Chrome extension does it on the page you have open, with no copying and pasting: tech stack, SEO, fonts, colors and CSS, and it sees the page the way your browser renders it (here we only read the HTML the server sends).
How do I find out what WordPress theme a site uses?
Paste its address above and click Analyze. The tool looks for the theme folder in the page’s code (wp-content/themes/…) and reads its style.css, where the theme declares its name, version and author.
Is it free?
Yes, free and with no sign-up. It’s a sample of the Smart Design Inspector extension, which does this and much more on the website you have open.
Can it detect WordPress plugins too?
Yes, the ones that load something on the page you analyze: styles, scripts or classes. Plugins that work behind the scenes (security, backups, server caching) leave no trace in the HTML, and no tool can see them from the outside.
Why does another detector say “custom theme”?
Because it looks the theme up in its database and doesn’t find it. This tool doesn’t depend on a list: it reads the name and version from the theme’s own file.
Can a WordPress theme be hidden?
It can be made harder to find: some plugins change the wp-content paths or rename the theme folder, and others remove the generator tag. Hiding it completely is hard, because the browser has to download the theme’s styles and scripts to render the page.
Can I use the same theme on my site?
If it’s free, it’s in the WordPress theme directory. If it’s paid, the theme website we show you leads to its author, who sells the license. Downloading it from another site usually means an unlicensed copy.
Do you store the websites I analyze?
No. The site is read on the spot to give you the result, and neither the address nor the result is stored.
Does it work with sites that aren’t WordPress?
Yes. If the site isn’t WordPress, it tells you what it’s built with when its code gives it away: Shopify, Wix, Webflow, Squarespace, Framer, Next.js, Astro and others.
