We built the internet's fastest, most accurate tool for detecting which AI builder, CMS, or framework powers any website — completely free.
The web is being rebuilt with AI. New website builders like Framer, Lovable, Durable, and Bolt are changing how people create online. But identifying which tool was used — from the outside — is surprisingly hard.
AI Website Detector solves that problem. Paste any URL and within seconds you get a confident answer: what builder it uses, how we know, what technologies power it, and where it's hosted. No signup, no cost, no catch.
Framer, Durable, Lovable, Bolt, Wix AI, Hostinger AI, Gamma, and more.
WordPress, Ghost, Webflow, Squarespace, Wix, Shopify, and 20+ others.
Next.js, Gatsby, Nuxt, Astro, SvelteKit, and other coding tools.
We fetch the page and scan script tags, CSS classes, and inline code for builder-specific fingerprints.
CDN hostnames (e.g. assets.framer.com) and HTTP response headers reveal the underlying platform.
Generator meta tags, data attributes, and class name patterns confirm the builder with high precision.
Signals are weighted and combined into a 0–99% confidence score so you know how certain the result is.
