Is This Website Built With Netlify?

Paste any URL below. Our scanner checks 3 Netlify-specific fingerprints — scripts, CDN domains, HTML attributes, and HTTP headers — and returns a confidence score instantly.

How to Tell if a Website Uses Netlify

Identifying whether a website was built with Netlify 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 3 Netlify-specific signals, and returns a verdict with a confidence score.

You might want to detect Netlify 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 Netlify?

Netlify is a cloud-based hosting and continuous deployment platform widely adopted by developers, JAMstack teams, and frontend-focused organizations for deploying static sites, single-page applications, and serverless functions directly from Git repositories. AIWebsiteDetector.com identifies Netlify-powered sites by analyzing three distinct HTTP response headers that Netlify injects into served responses, providing reliable, header-level fingerprints that persist regardless of custom domain configuration or frontend framework in use. These headers serve as the primary detection signals in our engine, offering a precise and low-ambiguity method of attribution compared to platforms that rely solely on script tags or DNS patterns. Netlify operates on a freemium model, offering a generous free tier for personal and open-source projects alongside paid plans for teams requiring advanced build minutes, analytics, and edge function capabilities — meaning detected sites span everything from hobby portfolios to production-grade commercial applications. This broad deployment footprint, combined with consistent server-level header injection, makes Netlify one of the more reliably detectable hosting platforms in our database.

It is primarily used for business websites, portfolios, landing pages, and personal sites without coding knowledge.

Signs a Website Is Built With Netlify

Our detection engine checks 3 unique Netlify fingerprints. Here are the most reliable signals:

High Confidence

HTTP Response Headers

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

How to Manually Detect Netlify 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 netlify or netlify
  4. If found in script src, class names, or meta tags — it's likely Netlify

Method 2 — Browser DevTools Network Tab

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

How Our Netlify 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 3 Netlify-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

Frequently Asked Questions

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

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

Is your Netlify detector free?

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

How accurate is the Netlify detection?

We check 3 unique Netlify 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 Netlify 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.
