Get HTTP Headers is a fast, reliable online utility that retrieves and displays the HTTP request and response headers for any URL. Whether you’re debugging an API, auditing security headers, checking cache settings, or verifying content type and server information, this tool gives you a clear, readable view of the exact HTTP headers exchanged between client and server — with no installation required and no complicated setup.

Developers, SEOs, security analysts, and webmasters use this tool to quickly inspect headers such as Content-Type, Cache-Control, Set-Cookie, Strict-Transport-Security, Content-Security-Policy, Server, and X-Frame-Options. The output is presented in a structured format and includes both the request headers sent by the tool and the response headers returned by the server, making it easy to spot misconfigurations and opportunities for optimization.

How it works
Enter a valid URL (including http:// or https://) into the tool input field.
Choose options if available (follow redirects or not, show request headers, custom user-agent).
Click Inspect (or Get Headers).
The tool sends an HTTP HEAD (or optionally GET) request to the target server and collects the response headers.
Results are displayed in a readable table or code block showing header names and values, along with response status, final URL after redirects, and any redirect chain.
Use the copy button to copy the raw headers, or export as text/JSON for reporting.
