Platform Overviews
Duda
Duda is a professional website builder platform primarily targeting web design agencies, SaaS companies, and digital marketing firms that need to build and manage client sites at scale. Our detection engine identifies Duda-powered sites through a combination of 3 distinct script patterns, 8 HTML attributes or structural markup signatures, 3 CDN domains specific to Duda's content delivery infrastructure, and 1 characteristic HTTP response header that Duda injects into its served pages. These layered signals make Duda relatively straightforward to fingerprint, as its platform leaves consistent, recognizable traces across the DOM structure, asset loading behavior, and server response metadata. Duda operates as a hosted, white-label platform — meaning sites built on it are served through Duda's own infrastructure rather than self-hosted environments, which reinforces the reliability of CDN domain and header-based detection. This infrastructure consistency, combined with the platform's agency-focused positioning, means Duda sites tend to cluster around professional service, local business, and SMB verticals, giving detection results a high degree of contextual predictability.
Gamma
Gamma is an AI-powered presentation and website builder aimed at professionals, educators, and teams who need to create polished decks, documents, and landing pages without traditional design overhead. Sites built with Gamma are hosted on Gamma's own infrastructure under the gamma.app domain, making the hosting environment itself a reliable primary signal for detection. AIWebsiteDetector.com's detection engine identifies Gamma-built sites using a combination of 3 script patterns, 3 CDN domains, 3 HTML patterns, 2 HTTP headers, and 2 meta tag patterns — giving the engine multiple redundant signals to confirm attribution with high confidence even when pages are customized or embedded. The HTML patterns typically surface in structural attributes and class conventions injected by Gamma's rendering pipeline, while the script patterns reflect the platform's bundled JavaScript assets loaded consistently across published sites. The reliance on Gamma's own CDN infrastructure and proprietary HTTP response headers makes this one of the more straightforward builder fingerprints in the detection database, with little ambiguity between Gamma and other AI site builders. Gamma operates on a freemium model with paid plans for advanced features, and because virtually all published Gamma sites resolve through gamma.app subdomains or custom domains with consistent header signatures, detection accuracy remains exceptionally high across site types.
