Free theme detector

Free theme detector for all popular CMS

What CMS or theme does the site use? Our detector bypasses firewalls and captchas to accurately analyze 99.9% of websites with the help of AI. Paste any website address and the AI will tell you if the website is custom-developed or uses a system. Our system handles most known systems: WordPress, Shopify, Wix, Woocommerce... it recognizes them and shows what theme and plugins they use, and if our system doesn't know the system, the AI will show what can be known about it.

How it works

Three steps, no signup and nothing to install.

  1. Enter a website address

    Paste any URL into the box at the top of the page.

  2. We analyse the public page

    We read the same code every visitor's browser receives and match it against our fingerprints of themes, plugins and platforms.

  3. Get the full report

    See the CMS, theme, plugins and hosting in seconds, with a details page for every theme and plugin we find.

Why is ThemeDetective better than the others?

Most detectors give up as soon as a site is a little harder to read. We do not.

Why check a competitor's theme and plugins?

Knowing what a successful website runs on saves time and money:

  • Skip the trial and error. Choose themes and plugins that already work for sites like yours instead of testing dozens.
  • Check before you buy. See whether a premium theme or plugin is really used by sites you respect.
  • Understand the setup. Hosting, CDN and platform tell you a lot about how a site is built and how fast it can be.
  • Spot trends in your niche. See which platforms and tools are winning in your industry.
  • Get design inspiration. Find the theme behind a layout you like and see what it can do.

Frequently asked questions

What is a theme detector?

A theme detector is a free online tool that analyses a website and tells you which CMS it runs on, which theme it uses and which plugins are active. Enter the address of any website and you get the answer in seconds.

How can I find out what theme a website uses?

Paste the website address into the box at the top of this page. We read the public page, recognise the platform and the theme, and show you the result together with the plugins and the hosting.

Which platforms can you detect?

WordPress, Shopify, Joomla, Drupal, PrestaShop, OpenCart, Wix, Squarespace and many more. The full list is on the Top CMS page, and we keep adding new systems.

Can you detect plugins and apps as well?

Yes. For WordPress we list the plugins, and for Shopify and other platforms the apps and extensions that are visible in the public code of the site.

Does it work on sites protected by Cloudflare or a captcha?

In most cases, yes. Firewalls and captchas stop simple detectors, but we have additional ways to reach the page. If a site cannot be read at all, we tell you why instead of guessing.

How do I find out what theme a Shopify store uses?

Enter the store address, with or without the .myshopify.com name. For Shopify stores we show the theme name and, when it is public, the version.

Why was no theme found on my site?

Custom-built sites, heavily modified themes and sites that hide their code do not expose a theme name. In that case you still see the platform, the plugins we could recognise and the hosting.

Is ThemeDetective really free?

Yes. There is no signup and no limit for normal use.

Can I download the theme I found?

When a free theme is available we link to its official page. Premium themes have to be bought from their authors.

Can I remove my website from your lists?

Yes. Use the "Remove my website" link in the footer and your site will be taken off the public lists.
