Get HTTP Headers

What is Get HTTP Headers?

Get HTTP Headers is a free online tool that fetches and displays the HTTP response headers for any URL. You enter a website URL, and the tool sends a request and returns the status code, response time, and all headers grouped by category (Security, Caching, Content, Server, Connection, Cookies, Redirect, CORS, Other). A security score shows how many recommended security headers are present. Developers, DevOps engineers, and security auditors use it to verify server configuration, check security headers, debug CORS, and analyze caching. No account or signup is required.

The result includes an HTTP status hero (e.g., 200 OK, 301 Moved Permanently) with response time, total header count, and security header count. Security headers are checked against a list (Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, Permissions-Policy, Referrer-Policy) with a progress bar and pass/fail indicators. Headers are grouped into categories with copy buttons per header. Raw headers are shown in a pre block with a copy-all button. An info card explains security, caching, CORS, and cookie headers.

Who Benefits from This Tool

Developers benefit when debugging API responses, CORS, or caching. See exactly what headers the server sends. Verify Content-Type, CORS, or cache directives. The categorized display makes it easy to find specific headers.

Security professionals benefit when auditing sites. The security score and checklist highlight missing headers. Identify sites that need HSTS, CSP, or X-Frame-Options. Use it for client audits or compliance checks.

DevOps and site owners benefit when optimizing performance. Check cache headers (Cache-Control, ETag). Verify CDN or server headers. The response time metric helps assess latency.

Key Features

Status and Metrics

HTTP status code and text (e.g., 200 OK). Response time in milliseconds. Total header count. Security header count.

Security Headers Check

Checks for HSTS, CSP, X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, Permissions-Policy, Referrer-Policy. Score shows how many are present. Progress bar and pass/fail per header.

Categorized Headers

Headers grouped into Security, Caching, Content, Server, Connection, Cookies, Redirect, CORS, Other. Each header has a copy button. Easy to scan and copy values.

Raw Headers

Full raw header block in a pre element. Copy All button copies the entire block. Useful for sharing or documentation.

Info Card

Explains security headers, caching, CORS, and Set-Cookie. Tips for improving configuration.

How to Use

1. Enter the URL. Type the full URL (e.g., https://example.com).
2. Complete the captcha if required.
3. Click Get Headers. The tool fetches the URL and parses the response.
4. Review the status. Check HTTP status, response time, and security score.
5. Inspect headers by category. Use the grouped sections to find specific headers. Copy individual values or all raw headers as needed.

Common Use Cases

• Checking security headers (HSTS, CSP, X-Frame-Options, etc.)
• Debugging CORS configuration
• Verifying cache headers (Cache-Control, ETag)
• Inspecting Content-Type and other content headers
• Auditing server configuration
• Debugging API or redirect behavior

Tips & Best Practices

Use HTTPS URLs for accurate security header checks. Response time varies by server and network. Run multiple times to see consistency. For security audits, aim for a high security score. Missing headers can expose sites to XSS, clickjacking, or other attacks. The tool shows what the server sends; it does not modify or fix headers.

Limitations & Notes

The tool sends a request from its server. Results reflect what the server returns to that request. Some sites may block or alter responses for non-browser clients. Redirects are followed; the final response is shown. The tool does not execute JavaScript. Cookies set by the response are shown but not persisted. The tool does not store your URLs.
