How It Works

1. HTTP Request - Fetches the webpage using standard HTTP
2. Header Analysis - Checks server headers for technology signatures
3. HTML Parsing - Scans HTML for framework-specific patterns
4. Script Detection - Analyzes loaded JavaScript files
5. CSS Analysis - Checks stylesheet sources
6. Meta Tag Extraction - Reads generator and other meta tags

Example Usage

{
  "urls": [
    "https://competitor1.com",
    "https://competitor2.com",
    "https://competitor3.com"
  ]
}

Find Shopify Stores (combine with other data sources)

Use this actor to verify which websites from your lead list are using Shopify, then filter your outreach accordingly.

Technology Audit

{
  "urls": ["https://your-company.com"],
  "maxUrls": 1
}

Error Handling

If a website cannot be analyzed, the result includes:

{
  "url": "https://example.com",
  "success": false,
  "error": "Request timed out",
  "error_type": "timeout"
}

Error types: timeout, connection_error, redirect_error, unknown_error

Limitations

• Only analyzes publicly accessible pages
• Some technologies may not be detectable if loaded dynamically after page load
• Version detection is limited to common frameworks
• Single-page applications may require the main page to load technology indicators
