HTTP Headers Analyzer
Fetch and inspect the HTTP response headers from any URL.
Examples
HTTP Headers Analyzer
Fetches the HTTP response headers from a URL and displays them with notes on security-relevant headers.
What This Tool Shows
- All Response Headers: Every HTTP header returned by the server
- Security Headers: Flags presence/absence of HSTS, CSP, X-Frame-Options, X-Content-Type-Options
- Server Header: Server software identifier if the server exposes it
- Cache Headers: Cache-Control and related caching directives
- Status Code: The HTTP response status code
Note
Headers are fetched from our server, not your browser. This means you see the raw server response without browser-added headers.
