AI Website Detector
Instantly find out if any website was built with AI — and which tool was used.
Our detector identifies Framer, Lovable, Bolt, Durable, Wix AI, 10Web, Mixo, Gamma, and 30+ more AI builders from a single URL.
AI Builders We Detect
These AI-powered platforms each leave unique fingerprints in their generated websites. Our engine recognizes all of them.

AI-powered visual website builder with built-in CMS
Lovable
Build full-stack web apps by chatting with AI
Bolt
AI app builder powered by StackBlitz WebContainers
Durable
Generate a business website in 30 seconds with AI
Wix AI
Wix's AI website creation tool
10Web
AI WordPress builder with automated hosting
Mixo
AI landing page builder for startups
Gamma
AI presentation and web page builder
How AI Detection Works
AI website builders produce consistent, identifiable patterns in the websites they generate. These patterns — called fingerprints — appear in JavaScript files, CDN domains, HTML structure, and HTTP headers. Our engine cross-references 80+ signals per page to determine both whether AI was used and which AI builder was responsible.
Enter any website URL
Paste the URL of any website — from a startup's landing page to a large e-commerce store.
We analyze AI fingerprints
Our engine checks HTML, JavaScript bundles, CDN patterns, component architecture (Shadcn/Lucide/Radix), AI code signals, and bundle artifacts from Lovable, Bolt, and v0.
Get an AI probability score
Receive a 0–99% AI probability score, the detected builder name, a verdict label (AI-Native Build / AI-Augmented Development / etc.), and a full reasoning explanation.
AI Probability Score
Every scan produces an AI probability score from 0% to 100%. Scores above 75% indicate an AI-native builder. Scores of 25–74% suggest AI-assisted development (like WordPress with AI plugins). Scores below 25% indicate traditional or custom-coded websites.

Frequently Asked Questions
What is an AI website detector?
An AI website detector analyzes the technical fingerprints of a website to determine whether it was built with an AI-powered website builder. Tools like Framer, Lovable, Bolt, Durable, and Wix AI each leave distinct signals in their generated code — our engine identifies these patterns.
Can you really detect AI-generated websites?
Yes. AI website builders produce consistent, identifiable patterns in their output — specific JavaScript libraries, CDN domains, meta tags, HTML structures, and bundle artifact strings. Our detector achieves 95%+ accuracy on major AI builders. For vibe-coded sites (Lovable/Bolt on custom domains), we scan JS bundles for artifact strings like 'lovable-uploads', 'gptengineer', and 'bolt-generated' that survive even when platform branding is stripped.
What AI builders can you detect?
We detect 30+ AI builders including Framer, Lovable, Bolt (StackBlitz), Durable, Wix AI, 10Web, Mixo, Gamma, Hostinger Horizons, Typedream, and more. We also detect traditional builders like WordPress, Webflow, and Shopify. Custom-domain deployments are handled through bundle artifact scanning and stack heuristics.
Is this the same as detecting AI-generated content?
No. This tool detects which AI platform was used to build the website's structure and code — not whether the website's text or images were AI-generated. For content detection, you would need a separate AI content detector.
How does the AI probability score work?
Our AI probability score (0–99%) is calculated from weighted signals: builder fingerprint match (dominant weight), component architecture signals (Shadcn UI, Lucide, Radix UI), AI code signals (API endpoints, SDK references), design heuristics, hidden patterns, and JavaScript bundle artifacts. AI-native builders score 90–99%. Vibe-coded Next.js+Tailwind stacks score 65%+. Traditional platforms score 20–30%.
Is this tool free?
Yes, completely free. No account, no API key, no rate limits for normal use. Just enter a URL and get your results instantly.
