Wappalyzer has been the go-to website technology detector for years. But its free tier has become increasingly limited — you get only a handful of lookups before hitting a paywall, and the browser extension has removed features from the free version. If you’re looking for a Wappalyzer alternative that gives you more data, better AI detection, or a fully free experience, this guide covers the best options available in 2026.

Why People Are Looking for Wappalyzer Alternatives

Wappalyzer is still a solid tool, but there are real reasons to look elsewhere:

  • Paywall on free tier: The free browser extension now shows limited results. Getting technology stacks for multiple sites requires a paid plan starting at $99/month.
  • 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)
  • JavaScript frameworks (React, Next.js, Vue, Angular, Svelte, Nuxt)
  • E-commerce platforms (Shopify, WooCommerce, Magento, PrestaShop)
  • CMS platforms (WordPress, Ghost, Strapi, Drupal)
  • Hosting providers and CDNs

    • What makes it different: AIWebsiteDetector doesn’t just list detected technologies — it gives you a Yes/Maybe/No verdict on whether the site was built with AI, along with the specific builder fingerprint and confidence score. No other tool does this.

    Pricing: Completely free for single scans. API access available for developers.

    Best for: Understanding industry trends, not individual site detection.
