How to Tell if a Website Uses Contentful
Identifying whether a website was built with Contentful 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 Contentful-specific signals, and returns a verdict with a confidence score.
You might want to detect Contentful 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 Contentful?
Contentful is the world's leading headless Content Management System, used by enterprise teams at Nike, Spotify, and Burger King to manage content across websites, apps, and digital experiences from a single platform. Unlike traditional CMS platforms, Contentful separates content storage from presentation entirely — it provides a REST API and GraphQL API that any frontend framework can query, then renders content through whatever technology the team chooses. This architecture means Contentful often powers Next.js, Gatsby, or Nuxt frontends rather than having its own rendering layer. Sites backed by Contentful are identifiable through their media CDN domains: images.ctfassets.net and downloads.ctfassets.net serve all stored assets, and these URLs appear in image src attributes and link hrefs throughout the page. Contentful plans start at a free Community tier, with Team plans from $300/month for professional workflows.
It is primarily used for content-driven websites, blogs, news sites, documentation, and publishing platforms.

Our detection engine checks 7 unique Contentful fingerprints. Here are the most reliable signals:
CDN Domain
Assets (images, scripts, fonts) are loaded from Contentful-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.
images.ctfassets.netdownloads.ctfassets.netJavaScript / Script Files
Contentful loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.
contentfulcdn.contentful.comHTML Attributes & Class Names
Contentful injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.
contentfulctf-Meta Tags
Some Contentful sites include a generator meta tag or other platform-specific meta elements in the document head.

Method 1 — View Page Source
- Open the website in your browser
- Press

Ctrl+F) forcontentfulorcontentful - If found in script src, class names, or meta tags — it's likely Contentful
Method 2 — Browser DevTools Network Tab

How Our Contentful 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 Contentful-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 can I tell if a website was built with Contentful?
The most reliable ways to detect Contentful are: (1) open DevTools → Network tab and look for requests to Contentful-specific CDN domains, (2) view page source and search for Contentful-specific class names or data attributes, (3) use our free scanner — we check 7 detection signals automatically and return a confidence score.
Is your Contentful detector free?
Yes, completely free. Paste any URL into our scanner and we'll analyze it for Contentful fingerprints immediately. No account required, no limits on scans.
How accurate is the Contentful detection?
We check 7 unique Contentful 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 Contentful 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.
