Input

Parameter	Type	Required	Description
urls	array	Yes	List of website URLs to analyze

Example Input

{
  "urls": [
    "https://stripe.com",
    "https://github.com",
    "https://shopify.com"
  ]
}

Output

Each website returns comprehensive technology data:

{
  "url": "https://stripe.com",
  "domain": "stripe.com",
  "frontend_frameworks": ["React", "Next.js"],
  "javascript_libraries": ["Lodash"],
  "css_frameworks": ["Tailwind CSS"],
  "cms": null,
  "ecommerce_platform": null,
  "backend_technology": "Node.js",
  "hosting_provider": "AWS",
  "cdn": "Cloudflare",
  "web_server": "nginx",
  "analytics": ["Google Analytics", "Segment"],
  "tag_managers": ["Google Tag Manager"],
  "security_headers": {
    "strict-transport-security": "max-age=31536000",
    "content-security-policy": "default-src 'self'...",
    "x-content-type-options": "nosniff"
  },
  "has_https": true,
  "has_hsts": true,
  "all_technologies": ["AWS", "Cloudflare", "Google Analytics", "Lodash", "Next.js", "nginx", "Node.js", "React", "Segment", "Tailwind CSS"],
  "technology_count": 10,
  "scraped_at": "2024-01-15T10:30:00.000000",
  "scrape_success": true
}

How It Works

The detector analyzes websites through multiple methods:

1. HTML Analysis - Scans page source for framework signatures, library imports, and technology markers
2. Header Inspection - Examines HTTP response headers for server info, CDN indicators, and language hints
3. Meta Tag Extraction - Reads generator meta tags that reveal CMS information
4. Pattern Matching - Uses extensive signature database to identify 50+ technologies

Technology Detection Accuracy

• High confidence for major frameworks (React, Vue, Angular, WordPress, Shopify)
• Medium confidence for server-side technologies (depends on header exposure)
• Detection based on publicly visible indicators only

Pricing

Pay per result: $0.002 per website (that's $2 per 1,000 websites)

Limitations

• Cannot detect technologies that don't leave visible traces
• Server-side detection depends on headers being exposed
• Some sites may use obfuscation
• Cloudflare and similar services may limit header visibility
