Best Wappalyzer Alternatives in 2026 (Free & Better Options)

No AI builder detection: Wappalyzer doesn't distinguish between AI-native builders (Framer, Lovable, Bolt) and traditional builders. If you're researching the modern web stack, this is a significant gap.

No confidence scores: Wappalyzer gives you a list of detected technologies but no indication of how confident the detection is.

Limited export/API on free tier: Bulk lookups and API access are enterprise features.

1. AIWebsiteDetector.com — Best for AI Builder Detection

AIWebsiteDetector.com is the top Wappalyzer alternative if you care about AI builder detection. It identifies whether a site was built with Framer, Webflow, Lovable, Bolt, Durable, v0, Replit, or 80+ other builders — and gives a confidence score with an AI probability verdict.

What it detects:

AI website builders (Framer, Lovable, Bolt, Durable, v0, Replit, and 80+ more)

Traditional builders (Webflow, Wix, Squarespace, WordPress, Shopify)
