Frequently Asked Questions

🔍 What are HTTP headers?

Headers are metadata sent with HTTP requests/responses containing information about the server, content type, caching, security policies, and more.

🔒 Is this safe to use?

Yes! We only fetch headers - no data is stored, no cookies are saved. All requests are made client-side.

⚡ How accurate is this?

100% real-time. We make actual HTTP requests and show exactly what headers the server returns.

🌐 Can I inspect any website?

Yes, any public website. Note: Some sites may block automated requests (returns 403/429).
