Q: Is an AI website detector accurate?

[AIWebsiteDetector.com](/) achieves high accuracy for sites hosted on known platforms (Framer, Webflow, WordPress, Shopify, etc.). Detection accuracy is lower for vibe-coded sites deployed without platform fingerprints.

Q: How many builders can it detect?

[AIWebsiteDetector.com](/) detects 80+ website builders, CMS platforms, e-commerce systems, and JavaScript frameworks, with specific fingerprints for AI-native platforms.

AI-native platforms (Framer, Lovable, Bolt, Durable, Gamma)

Traditional platforms with AI features (Wix AI, Squarespace AI)

Vibe-coded custom sites (no platform, but AI-generated code)

A site can have a "No" builder detection (no specific platform identified) but still score "Maybe" on AI probability if the code structure suggests AI generation.

Can AI detection be fooled?

Yes — a determined developer can remove generator tags, proxy CDN assets through a custom domain, and obfuscate class names. But this requires active effort. Most sites built on platforms don't bother to mask their identity.
