Platform Overviews
Sanity
Sanity is a modern headless CMS with a real-time 'content lake' — a cloud database optimized for structured content with a powerful query language (GROQ) and flexible schema definition. Unlike other headless CMS platforms, Sanity stores all content in a single collaborative workspace where editors can see changes in real-time, similar to Figma for content. It's popular with digital agencies and product teams who need a flexible, developer-configurable CMS that doesn't force a rigid content model. Sanity-powered sites serve all media through cdn.sanity.io, and this CDN domain in image URLs is the primary detection signal. The Sanity Studio (the editing interface) is typically deployed as a separate /studio route on the same domain, and some sites leave the __sanity object in their JavaScript globals. Sanity pricing is usage-based with a generous free tier and Growth plans from $15/month.
Webflow
Webflow is the most powerful no-code website builder available, offering pixel-perfect visual design control with a built-in CMS, e-commerce, and advanced animation capabilities. Unlike most builders, Webflow gives designers and developers full CSS control through a visual interface — making it popular with agencies, freelancers, and in-house design teams who need professional results without a frontend developer. Every Webflow page is uniquely identifiable through injected data-wf-page and data-wf-site attributes on the HTML element, proprietary CSS classes (w-nav, w-layout-grid, w-dyn-item), and assets served from uploads-ssl.webflow.com and assets.website-files.com CDNs. The Webflow JS runtime (webflow.js) is loaded on every published site, and Webflow-hosted sites return server: Webflow in their HTTP headers. Site plans start at $14/month, with workspace plans for agencies from $19/month.
Key Differences

- Webflow scores higher on AI involvement (90/100 vs 20/100 for Sanity), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies Sanity using 5 fingerprint patterns and Webflow using 13 patterns — more signals generally means more reliable detection.
- Sanity serves assets from
/cdn\.sanity\.io/iwhile Webflow uses/assets\.website-files\.com/i— making CDN domain analysis one of the most reliable ways to distinguish them.
