Is This Website Built With Webflow?

Paste any URL below. Our scanner checks 13 Webflow-specific fingerprints — scripts, CDN domains, HTML attributes, and HTTP headers — and returns a confidence score instantly.

How to Tell if a Website Uses Webflow

Identifying whether a website was built with Webflow 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 13 Webflow-specific signals, and returns a verdict with a confidence score.

You might want to detect Webflow 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 Webflow?

Webflow is a no-code website builder with a powerful CMS and advanced design capabilities. It bridges the gap between design tools and code, offering pixel-perfect control without writing HTML/CSS. Webflow sites are identified by their unique CSS classes (w-nav, w-layout-grid) and assets served from webflow.com CDNs.

It is primarily used for marketing sites, landing pages, portfolios, and business websites — all generated from prompts or visual editors with AI assistance.

Signs a Website Is Built With Webflow

Our detection engine checks 13 unique Webflow fingerprints. Here are the most reliable signals:

High Confidence

CDN Domain

Assets (images, scripts, fonts) are loaded from Webflow-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.

High Confidence

JavaScript / Script Files

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

High Confidence

HTTP Response Headers

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

HTML Attributes & Class Names

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

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

Method 2 — Browser DevTools Network Tab

  1. Press F12 to open DevTools
  2. Click the Network tab and reload the page
  3. Filter by webflow in the search box
  4. If you see requests to Webflow-specific domains, it's confirmed

How Our Webflow 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 13 Webflow-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

Is your Webflow detector free?

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

How accurate is the Webflow detection?

We check 13 unique Webflow 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 Webflow 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.
