Fetches up to 32KB of the domain's HTML and response headers from the edge, then
fingerprints the content for known CMS platforms, JavaScript frameworks, CDN
providers, and analytics tools. Detection is based on meta generator tags, script
src patterns, response headers, and cookie names.
Use this tool when:
- You need to know what CMS (WordPress, Drupal, Shopify) a site runs.
- You are assessing a domain's infrastructure before a security review.
- You want to identify analytics or marketing tools a site embeds.
Do NOT use this tool when:
- You want HTTP headers and security posture — use `intel_http` instead.
- You want tracker database classification — use `get_domain` instead.
- You need robots.txt AI policy — use `intel_robots` instead.
Inputs:
- `domain` (query, required): Domain to fingerprint.
Returns:
- `cms`: detected content management system, or null.
- `frameworks`: JavaScript/backend frameworks detected.
- `cdn`: CDN provider detected, or null.
- `analytics`: analytics and tracking tools detected.
- `meta_generators`: raw meta generator tag values.
Cost:
- Free. No API key required.
Latency:
- Typical: 2-4s (HTML fetch), p99: 7s.
