AI Coding Tool
Astro is a ai coding tool with an AI Score of 65/100 (AI-Assisted). Our detection engine uses 6 signal patterns to identify Astro-built sites.
AI Website Builder
Framer is a ai website builder with an AI Score of 90/100 (AI-Native). Our detection engine uses 13 signal patterns to identify Framer-built sites.
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.
Framer is a design-first website builder aimed at product teams, designers, and startups who want to publish polished, interactive sites without writing backend code. AIWebsiteDetector.com identifies Framer-powered sites using a combination of 4 script patterns, 4 HTML patterns, 2 CDN domain signatures, 2 HTTP response headers, and 1 meta tag pattern — making it one of the more technically fingerprint-rich builders in our detection database. The script patterns typically surface Framer's proprietary runtime and animation libraries, while the CDN domain signatures point to Framer's dedicated asset delivery infrastructure, giving the detection engine multiple independent signals to work with. HTTP headers and embedded meta tags further corroborate identification, particularly on sites where script obfuscation might otherwise reduce confidence. Framer hosts all sites on its own infrastructure by default, meaning self-hosted deployments are rare and the platform's fingerprints remain highly consistent across the detected site population — a characteristic that keeps false-positive rates low.
