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.
