Platform Overviews
Contentful
Contentful is the world's leading headless Content Management System, used by enterprise teams at Nike, Spotify, and Burger King to manage content across websites, apps, and digital experiences from a single platform. Unlike traditional CMS platforms, Contentful separates content storage from presentation entirely — it provides a REST API and GraphQL API that any frontend framework can query, then renders content through whatever technology the team chooses. This architecture means Contentful often powers Next.js, Gatsby, or Nuxt frontends rather than having its own rendering layer. Sites backed by Contentful are identifiable through their media CDN domains: images.ctfassets.net and downloads.ctfassets.net serve all stored assets, and these URLs appear in image src attributes and link hrefs throughout the page. Contentful plans start at a free Community tier, with Team plans from $300/month for professional workflows.
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
- Contentful is a CMS 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 20/100 for Contentful), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies Contentful using 7 fingerprint patterns and Webflow using 13 patterns — more signals generally means more reliable detection.
- Contentful serves assets from
/images\.ctfassets\.net/iwhile Webflow uses/assets\.website-files\.com/i— making CDN domain analysis one of the most reliable ways to distinguish them.
