Platform Overviews
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
- React is a AI Coding Tool while Webflow is a AI Website Builder — they serve different primary use cases and aren't always direct alternatives.
- Webflow scores higher on AI involvement (90/100 vs 65/100 for React), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies React using 11 fingerprint patterns and Webflow using 13 patterns — more signals generally means more reliable detection.
- React serves assets from
/unpkg\.com\/react/iwhile Webflow uses/assets\.website-files\.com/i— making CDN domain analysis one of the most reliable ways to distinguish them.
