📋 How It Works

Mode 1: Reverse Lookup (Tech → Domains)

Find all domains that use a specific technology. Perfect for lead generation, competitive research, and market sizing.

{
  "reverseLookup": true,
  "technologies": ["Shopify", "WordPress", "Cloudflare"],
  "maxItems": 50,
  "useCache": true
}

Provider chain:

1. Wappalyzer public technology pages (structured website tables)
2. Search-engine fallback for unmapped technologies
3. Local SQLite cache deduplication
4. Optional domain validation via lightweight technology signature checks

Mode 2: Forward Scan (Domain → Tech)

Scan one or more domains to detect their technology stack.

{
  "reverseLookup": false,
  "domains": ["shopify.com", "stripe.com"],
  "maxItems": 10,
  "useCache": true
}

Detection methods:

• HTML meta tags (generator etc.)
• Script/CDN URLs (e.g. cdn.shopify.com, js.stripe.com)
• JavaScript patterns
• CSS class conventions
• Cookies and headers

❓ FAQ

Q: How is this different from BuiltWith? A: BuiltWith is a paid service. This actor provides similar reverse-lookup and tech-detection capabilities using public sources and local detection — no subscription required.

Q: Which technologies are supported? A: 50+ pre-mapped technologies including Shopify, WordPress, WooCommerce, Wix, Squarespace, Magento, Webflow, React, Next.js, Stripe, PayPal, Cloudflare, Google Analytics, Google Tag Manager, Hotjar, HubSpot, and Intercom. For unmapped technologies, the actor falls back to search-engine discovery.

Q: How accurate are traffic and spend estimates? A: These come from public Wappalyzer listings and should be treated as estimates, not precise metrics.

Q: Can I use this for batch processing? A: Yes. Add multiple technologies in the technologies array or multiple domains in the domains list. Use maxItems to control result volume per technology.
