Website Technology Checker

How to check what a website is built with

1. Paste the complete public URL, including https://.
2. Run the check and review each technology and its evidence.
3. Check another page if a feature, such as a shop, lives on a separate URL.
4. Confirm findings with the site owner before planning a migration or integration.

Which technologies can this checker detect?

• CMS and ecommerce: WordPress resource paths, Shopify and Wix assets, and generator tags for WordPress, Drupal, Joomla and Ghost.
• Frameworks and libraries: public signals for Next.js, React, Vue, Nuxt, Bootstrap and jQuery.
• Analytics: Google Analytics and Google Tag Manager script references.
• Infrastructure: Cloudflare headers, Apache or nginx server headers, and PHP headers when exposed.

For example, a /wp-content/ resource can indicate WordPress, while a /_next/static/ resource can indicate Next.js. A result identifies a detected signal rather than a verified inventory of the website.

Why might a technology be missing?

The checker inspects returned HTML and response headers. It does not execute JavaScript, sign in, or inspect private server code. Bundled scripts, consent-dependent analytics, hidden headers and blocked requests can limit detection. No detected signal does not prove that a technology is absent.

The results do not establish software versions, security vulnerabilities or ownership.
