Platform Overviews
Webflow
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.
Astro
Astro is a modern static site generator and web framework designed for content-focused websites, widely adopted by developers building blogs, documentation platforms, marketing sites, and portfolios who prioritize performance through minimal JavaScript delivery. AIWebsiteDetector.com identifies Astro-powered sites using a combination of 2 distinct script patterns, 3 HTML patterns, and 1 HTTP header signal — a precise fingerprint that reflects how Astro renders its component island architecture into the DOM. The HTML patterns typically surface in the markup structure and custom attributes Astro injects during its build process, while the script patterns correspond to Astro's client-side hydration modules that accompany interactive components on the page. The HTTP header signal further corroborates detection, often appearing in server or CDN response metadata associated with Astro's deployment targets such as Netlify, Vercel, and Cloudflare Pages. Astro is open-source and free to use, with hosting costs determined entirely by the chosen deployment platform, making it a common choice across a wide spectrum of project scales — from personal sites to enterprise documentation. This multi-signal detection approach gives AIWebsiteDetector.com high confidence when classifying Astro sites, as the combination of build-output HTML markers and runtime script patterns is difficult to mask without fundamentally altering Astro's default output behavior.
