Sanity is a cms with an AI Score of 20/100 (Traditional). Our detection engine uses 5 signal patterns to identify Sanity-built sites.
AI Website Builder
Webflow is a ai website builder with an AI Score of 90/100 (AI-Native). Our detection engine uses 13 signal patterns to identify Webflow-built sites.
Sanity is a headless content management system built for developers and digital teams who need a flexible, structured content backend powering websites, apps, and omnichannel publishing workflows. AIWebsiteDetector.com identifies Sanity-powered sites using a combination of two distinct script patterns, two HTML patterns, and one CDN domain signature that Sanity injects into its front-end delivery layer. These signals — including characteristic markup attributes embedded in the document structure and JavaScript references tied to Sanity's content lake infrastructure — allow the detection engine to fingerprint Sanity deployments with high confidence across a wide range of site types, from editorial platforms to e-commerce storefronts. The CDN domain pattern is particularly reliable, as Sanity routes structured content assets through its own dedicated delivery network, leaving a consistent and identifiable network footprint. Sanity operates on a usage-based pricing model with a generous free tier, and because it is typically deployed headlessly, it often surfaces alongside frameworks like Next.js or Gatsby — making the combination of HTML and script signals essential for accurate attribution.
Webflow is a visual web design and development platform used by designers, agencies, and marketing teams to build responsive websites without writing code, though it generates clean, standards-compliant HTML and CSS under the hood. Sites built on Webflow are reliably identified through a combination of technical signals, including 3 distinct JavaScript script patterns loaded from Webflow's asset pipeline, 4 characteristic HTML attributes and structural patterns embedded in the page markup, 2 CDN domain signatures used to serve static assets, 2 HTTP response headers that indicate Webflow's hosting infrastructure, and 2 meta tag patterns injected into the document head. These overlapping signal layers allow AIWebsiteDetector.com's detection engine to identify Webflow-powered sites with high confidence across a wide range of site categories, from portfolio and agency sites to SaaS marketing pages and e-commerce storefronts. Webflow is unique in that it offers both a hosted platform (webflow.io subdomains and custom domains routed through its CDN) and the ability to export code for self-hosting, though the exported code still retains several of Webflow's structural HTML fingerprints, making detection possible even in non-hosted deployments. The platform's official presence is at webflow.com, and its hosting tier ranges from free plans with branded subdomains to enterprise plans with advanced CMS and logic capabilities.
