This CMS detector tells you which content management system or site builder a website runs on. Enter a URL and it reads the page's HTML and response headers for the traces 11 platforms leave: WordPress, Shopify, Wix, Squarespace, Webflow, Joomla, Drupal, Magento, Ghost, HubSpot and Framer. You also see the Server, X-Powered-By and Generator values the site sends. It is free and needs no signup.
How to use the CMS detector
- 1Type the site's address, such as example.com. Any page on the site works, and the homepage is usually best.
- 2Press Check, or hit Enter.
- 3Read Platform detected. If the page matches more than one platform, the others appear under Also matched.
- 4Read the Server, X-Powered-By and Generator rows below it for extra clues. A row only appears when the site sends that value.
When to use it
- You like a competitor's site and want to know what it is built with.
- A prospect asked for help with their website and you need to know if your team can work on that platform.
- You are about to quote for a redesign or a migration and want to know what you are moving away from.
- You took over a site with no handover notes and need to know which platform it runs on.
Worked example
A custom-built site
We checked our own site.
- URL to check
- https://searchblueprint.io
- Platform detected
- Unknown / custom
- Server
- Vercel
- X-Powered-By
- Next.js
No CMS matched, and that is correct: the site is custom code, not a CMS. The headers fill in the rest. Next.js is the framework the site is written in, and Vercel is the platform serving it. So Unknown / custom is often an answer in its own right, and the header rows tell you what to look at next.
The 11 platforms it detects
| Platform | One of the traces it looks for |
|---|---|
| WordPress | wp-content or wp-includes paths |
| Shopify | files served from cdn.shopify.com |
| Wix | files from static.wixstatic.com |
| Squarespace | files from static1.squarespace.com |
| Webflow | data-wf-page attributes |
| Joomla | /media/jui/ paths |
| Drupal | /sites/default/files paths |
| Magento | /static/version paths |
| Ghost | a Ghost generator tag |
| HubSpot | scripts from hs-scripts.com |
| Framer | files from framerusercontent.com |
When a page has a generator meta tag naming WordPress, Drupal, Joomla, Wix or Shopify, the tag decides the answer.
