Platform Overviews
Bubble
Bubble is a no-code and AI-assisted full-stack application development platform used by entrepreneurs, startups, and non-technical founders to build web applications without writing traditional code. Our detection engine identifies Bubble-powered sites using a combination of 2 script patterns, 2 HTML patterns, and 1 HTTP header, giving it a well-rounded fingerprint across multiple layers of a page's technical stack. Script patterns typically involve Bubble's proprietary runtime JavaScript loaded from their CDN infrastructure, while HTML patterns reflect Bubble-specific markup attributes and structural elements injected into the rendered DOM. The HTTP header signal further distinguishes Bubble deployments at the network response level, making it detectable even when frontend code is partially obfuscated or customized. Bubble applications are hosted on Bubble's own cloud infrastructure by default, with custom domains available on paid plans, and this consistent hosting environment contributes to reliable, high-confidence detection across the wide variety of app types — from marketplaces to SaaS dashboards — that its users build on the platform.
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.
