Get HTTP Headers

About This Tool

So you want to see what’s going on behind the scenes when your browser talks to a website? That’s where "Get HTTP Headers" comes in. It’s not flashy, and it won’t win any design awards, but it does one thing well: it shows you the raw HTTP response headers from any URL you throw at it. Think of HTTP headers like the envelope on a letter. The content inside is the webpage you see, but the envelope has all the metadata—where it came from, how it was sent, caching rules, security settings, and more. This tool peels back that layer so you can inspect it. Whether you're debugging a redirect, checking if HSTS is enabled, or just curious about server behavior, this gives you a quick, no-nonsense look under the hood. No login. No tracking. Just paste a URL and hit go.

FAQ

Why can’t I see headers for some sites?
Some websites block automated requests or require specific headers to respond. If you get an error or empty result, it might be due to server-side restrictions, firewalls, or anti-bot measures. Also, if the site uses Cloudflare or similar services, you might only see their headers, not the origin server’s.

Is this safe to use?
Yes, as long as you’re entering public URLs. The tool doesn’t store your requests, and it only fetches headers—no content, no cookies, no personal data. Just don’t paste sensitive internal URLs unless you’re sure they’re not exposing private info.
