Is This Website Built With Drupal?

Paste any URL below. Our scanner checks 7 Drupal-specific fingerprints — scripts, CDN domains, HTML attributes, and HTTP headers — and returns a confidence score instantly.

How to Tell if a Website Uses Drupal

Identifying whether a website was built with Drupal used to require technical expertise — inspecting source code, tracing network requests in DevTools, and knowing which patterns to look for. Our free scanner automates all of that: it fetches the page, analyzes 7 Drupal-specific signals, and returns a verdict with a confidence score.

You might want to detect Drupal for competitive research, due diligence before acquiring a site, or simple curiosity. Whatever the reason, this page covers every method — automated and manual.

What is Drupal?

Drupal is a powerful open-source CMS popular with governments and enterprises. Drupal sites expose x-generator: Drupal headers, /sites/default/files/ paths, and drupal-specific CSS classes.

It is primarily used for content-driven websites, blogs, news sites, documentation, and publishing platforms.

Signs a Website Is Built With Drupal

Our detection engine checks 7 unique Drupal fingerprints. Here are the most reliable signals:

High Confidence

JavaScript / Script Files

Drupal loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.

drupal/sites/default/files
High Confidence

HTTP Response Headers

Drupal-hosted sites respond with specific HTTP headers that identify the platform or infrastructure. These are visible in DevTools → Network tab.

x-generatorx-drupal-/
Medium Confidence

HTML Attributes & Class Names

Drupal injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.

Medium Confidence

Meta Tags

Some Drupal sites include a generator meta tag or other platform-specific meta elements in the document head.

How to Manually Detect Drupal Websites

Method 1 — View Page Source

  1. Open the website in your browser
  2. Press Ctrl+U (Windows) or Cmd+Option+U (Mac)
  3. Search (Ctrl+F) for drupal or drupal
  4. If found in script src, class names, or meta tags — it's likely Drupal

Method 2 — Browser DevTools Network Tab

  1. Press F12 to open DevTools
  2. Click the Network tab and reload the page
  3. Filter by drupal in the search box
  4. If you see requests to Drupal-specific domains, it's confirmed
Faster: Skip the manual steps — paste the URL into our scanner above and we check all 7 signals in seconds.

How Our Drupal Detector Works

When you submit a URL, our engine fetches the page from its server — just like a browser would — then analyzes the response across 7 Drupal-specific fingerprints:

Script analysis

We scan all loaded JavaScript files for known CDN paths and runtime names

CDN domain matching

We cross-reference every asset request against known platform CDNs

HTML pattern scanning

We search the DOM for platform-specific class names and data attributes

Header inspection

We read HTTP response headers that identify the server or platform

Meta tag extraction

We check generator and other meta tags in the document head

Confidence scoring

We weight each matched signal and normalize to a 0–99% score

How to Build a Similar Website With Drupal

Install Drupal from https://drupal.org, set up your content models, and connect a frontend framework like Next.js or Gatsby to display your content.

Other popular CMS platforms include WordPress, Ghost, Contentful, Sanity, and Strapi.

Frequently Asked Questions

How can I tell if a website was built with Drupal?

The most reliable ways to detect Drupal are: (1) open DevTools → Network tab and look for requests to Drupal-specific CDN domains, (2) view page source and search for Drupal-specific class names or data attributes, (3) use our free scanner — we check 7 detection signals automatically and return a confidence score.

Is your Drupal detector free?

Yes, completely free. Paste any URL into our scanner and we'll analyze it for Drupal fingerprints immediately. No account required, no limits on scans.

How accurate is the Drupal detection?

We check 7 unique Drupal fingerprint signals across HTML, JavaScript, CDN domains, meta tags, and HTTP headers. Our confidence score reflects how many signals matched — a score above 70% is a strong indicator. We cap accuracy at 99% to reflect that all fingerprint-based detection is probabilistic.

Can Drupal sites be detected if they use a custom domain?

Yes. Custom domains don't hide the underlying platform. The JavaScript files, CDN requests, HTML attributes, and server headers all remain identifiable regardless of the domain name used. Our scanner fetches the page directly and analyzes its technical composition.
