Platform Overviews

Framer

Framer is a design-first website builder aimed at product teams, designers, and startups who want to publish polished, interactive sites without writing backend code. AIWebsiteDetector.com identifies Framer-powered sites using a combination of 4 script patterns, 4 HTML patterns, 2 CDN domain signatures, 2 HTTP response headers, and 1 meta tag pattern — making it one of the more technically fingerprint-rich builders in our detection database. The script patterns typically surface Framer's proprietary runtime and animation libraries, while the CDN domain signatures point to Framer's dedicated asset delivery infrastructure, giving the detection engine multiple independent signals to work with. HTTP headers and embedded meta tags further corroborate identification, particularly on sites where script obfuscation might otherwise reduce confidence. Framer hosts all sites on its own infrastructure by default, meaning self-hosted deployments are rare and the platform's fingerprints remain highly consistent across the detected site population — a characteristic that keeps false-positive rates low.
