What is a CMS detector?

A CMS detector is a web analysis tool that scans a webpage's HTML code to determine which Content Management System powers the site.

How do I check if a website is built with WordPress?

WordPress sites are identified by paths containing `/wp-content/`, `/wp-includes/`, the `wp-json` REST API endpoint, and generator meta tags.

Can this tool detect headless and static CMS platforms?

Yes. It detects headless CMS signatures such as Strapi, Contentful, Sanity, Ghost, and static site generators like Hugo, Gatsby, Astro, and Jekyll.

Does the tool reveal active themes and plugins?

If theme and plugin asset paths are publicly exposed in the HTML (such as `/wp-content/plugins/yoast-seo/`), the tool identifies and lists them in the report.

What if a site hides its CMS generator meta tag for security?

The detector checks multiple redundant signatures—including DOM markers, script namespaces, and asset CDN paths—to identify the CMS even when generator meta tags are removed.

Why did detection fail on a specific URL?

Some websites enforce strict anti-bot firewalls. Use 'Paste HTML Source' mode to paste the page's HTML directly for instant local detection.

Is this CMS detection tool free?

Yes. NexLove's CMS Detector is 100% free with unlimited domain searches.

Can I detect what page builder a WordPress site uses (e.g. Elementor, Divi)?

Yes. The scanner identifies major WordPress page builders including Elementor, Divi, Gutenberg, Beaver Builder, and WPBakery.

CMS Detector (What CMS Is That Website Using?)

Identify WordPress, Shopify, Webflow, Drupal, Joomla, Ghost, and custom CMS platforms on any website.

TL;DR: CMS Detector scans website pages to detect what Content Management System, theme, and plugin signatures are active.

How Do I Find Out What CMS a Website Is Using?

To find out what CMS a website uses, enter the site's URL into a CMS detector. The tool inspects public page metadata (like ``), known asset directory paths (`/wp-content/`, `/sites/default/files/`), CSS namespaces, and API endpoints to accurately identify WordPress, Webflow, Shopify, Drupal, Joomla, Ghost, Wix, or Squarespace.

Key Capabilities & Developer Best Practices

Fast In-Browser Processing: Zero server latency; code formatting, validation, and transformations execute in real time.
Complete Data Confidentiality: Work with sensitive API keys, production configs, and database records safely on your local device.
Standards-Compliant Output: Generates clean, RFC-compliant code ready for production deployment and clean Git diffs.

Safe & Transparent URL Inspection

All network queries only inspect public, non-authenticated headers and HTML assets. When analyzing pasted source code, processing runs 100% locally in your web browser with complete confidentiality.
