Headers only:No content is downloaded, only HTTP headers are analyzed.

How to Use HTTP Viewer

1
Enter a URL
Type or paste a website URL into the input field. Make sure to include the protocol (http:// or https://) for accurate header analysis.
Tip:You can test any publicly accessible website. Private or internal URLs are blocked for security reasons.
2
Send HTTP Request
Click 'Inspect Headers' to send a secure HTTP HEAD request to the URL and retrieve comprehensive response headers and metadata.
Tip:The tool uses HEAD requests to get headers without downloading the full page content, making it fast and efficient.
3
View Response Headers
Examine the categorized HTTP headers including server information, security headers, caching directives, and performance metrics.
Tip:Headers are organized by category to help you quickly find specific information about the server response.
4
Analyze Security & Performance
Review security headers like CSP and HSTS, check caching policies, response times, and understand server configuration details.
Tip:Use this information to optimize your own websites or troubleshoot HTTP-related issues.

Frequently Asked Questions

What types of URLs can I inspect?

You can inspect any publicly accessible HTTP or HTTPS URL. The tool blocks private IP addresses and internal networks for security reasons.

Why do some requests fail?

Requests may fail if the URL is invalid, the server is down, blocks HEAD requests, has strict CORS policies, or if you're trying to access private/internal addresses.

Is this tool secure to use?

Yes! The tool includes multiple security measures: rate limiting, IP blocking for internal networks, and only sends HEAD requests without downloading content.

Do you store the URLs I inspect?

No, URLs are processed server-side for CORS bypass but are not logged or stored anywhere. All data is immediately discarded after the response.

What's the difference between this and browser dev tools?

This tool can inspect any website's headers, while browser dev tools only show headers for pages you visit. It's also useful for quick header analysis without opening dev tools.
