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.
