Paste any URL to check if a website was created with an AI builder. We analyze 80+ technical signals and return a confidence score — instantly, for free.
Results are probabilistic based on technical signals — not a guarantee.
AI website detection is based on technical fingerprints — unique patterns left by each AI builder in the HTML, scripts, CDN domains, and HTTP headers.
Tools that generate complete websites from a prompt or business description using AI.
Platforms that write full-stack code from natural language — often deployed as websites.
AI-generated sites are often deployed to Vercel or Netlify and expose identifiable headers.
AI code generators frequently output React/Next.js apps with recognizable build patterns.
Beyond automated detection, here are patterns that often indicate an AI-generated website:
AI-generated websites often follow predictable hero → features → CTA patterns with minimal variation. The spacing and component hierarchy is unusually uniform.
AI-written content tends to be polished but generic — broad value propositions without specific details. Images are often from well-known stock providers.
AI website builders like Framer embed data attributes (data-framer-*), specific CDN domains (framerusercontent.com), or meta generator tags that reveal the tool used.
Sites built with AI tools are often hosted on Vercel, Netlify, or Cloudflare Pages — identifiable via HTTP response headers like x-vercel-id or cf-ray.
Most AI-built websites are static or use simple form integrations. The absence of custom API routes, CMS endpoints, or database connections suggests an AI builder.

This site may have been created using an AI-powered builder — based on detected technical signals.
Yes — with high accuracy for sites built with known AI website builders. AI builders like Framer, Durable, Wix ADI, and Lovable leave specific technical fingerprints: CDN domains, HTML attributes, API paths, and response headers that our engine checks against.
For popular AI builders, accuracy is 90–98%. Detection is probabilistic — we return a confidence score rather than a binary yes/no. Sites that heavily customize or obfuscate their output may score lower. We recommend treating results as strong indicators, not absolute certainty.
We detect 25+ AI-powered tools including Framer, Durable, Wix ADI, 10Web, Mixo, Hocoos, Lovable, Bolt, Gamma, Replit, and more. The full list is on our builders page.
AI-Built means the site was generated primarily by an AI tool (Framer, Durable, Lovable). AI-Assisted means AI tools were used in development but a human developer drove the architecture — common with GitHub Copilot or Cursor users.
A score near 0% doesn't always mean the site wasn't built with AI — some tools minimize their fingerprints or use custom domains that obscure detection. It means we couldn't find detectable AI signals.
Yes. Completely free, no account or credit card needed. We detect AI builders for anyone who asks.
