How to Tell if a Website Uses Framer Sites
Identifying whether a website was built with Framer Sites 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 Framer Sites-specific signals, and returns a verdict with a confidence score.
You might want to detect Framer Sites 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 Framer Sites?
Framer Sites is an AI-powered website builder developed by Framer, designed primarily for designers, startups, and creative professionals who want to ship polished, interactive web experiences without writing code. The platform generates modern, component-driven sites and hosts them on Framer's own infrastructure, making its technical fingerprint relatively consistent and reliable to detect. AIWebsiteDetector's detection engine identifies Framer Sites deployments using a combination of one distinct script pattern, one CDN domain, and one HTML pattern embedded in the page markup — signals that remain present across both free and paid Framer-hosted projects. These indicators appear reliably enough that the engine can flag Framer Sites with strong confidence during automated scans, even when sites use custom domains that obscure the Framer branding at the surface level. One characteristic that makes Framer particularly straightforward to fingerprint is its reliance on a proprietary CDN domain for asset delivery, which surfaces consistently in page requests regardless of how heavily a site has been customized through Framer's visual editor.
It is primarily used for marketing sites, landing pages, portfolios, and business websites — all generated from prompts or visual editors with AI assistance.

Our detection engine checks 3 unique Framer Sites fingerprints. Here are the most reliable signals:
CDN Domain
Assets (images, scripts, fonts) are loaded from Framer Sites-specific CDN domains. This is one of the most reliable signals because CDN domains are hard to hide.
framer.websiteJavaScript / Script Files
Framer Sites loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.
framer.websiteHTML Attributes & Class Names
Framer Sites injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.

How Our Framer Sites 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 Framer Sites-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 Framer Sites detector free?
Yes, completely free. Paste any URL into our scanner and we'll analyze it for Framer Sites fingerprints immediately. No account required, no limits on scans.
How accurate is the Framer Sites detection?
We check 3 unique Framer Sites 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 Framer Sites 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.
