Why check what a website is built with?
Found a site you love and want something similar? Knowing its theme and plugins gives you a head start. Checking a competitor shows what tools they invest in. And if you are taking over a client site, it tells you what you are dealing with before you log in.
Frequently asked questions
How does the CMS detector work?
It loads the page the way a browser would and looks for the fingerprints each platform leaves behind: file paths, code snippets, server headers and generator tags. For WordPress sites it also reads the theme's own details file to get the real theme name, author and version.
Can it find the exact WordPress theme?
Usually, yes. It reports the active theme and, for child themes, the parent theme it is built on, with a link to where it came from. Some agencies rename themes, in which case you will see the custom name.
Why are some plugins missing from the list?
Only plugins that load files on the page you checked can be seen from outside. Admin-only plugins (backups, security, SEO settings) leave no public trace. Checking a few different pages can reveal more.
Why does it say "not detected"?
Some sites are custom-built, or hide their platform on purpose. Sites behind strict firewalls may also block automated checks.
Is it legal to check what a website is built with?
Yes. The tool only reads information every visitor's browser already receives when opening the page.
Can you rebuild my site on WordPress or Shopify?
Yes. Migrating sites from builders like Wix or Squarespace to WordPress or Shopify, and redesigning existing ones, is part of what I do.
