HTTP Header Parser
Paste response headers and get a readable breakdown of status, cache behavior, content type, redirects, and security hints.
Read response headers at a glance
HTTP response headers hold the answers to a lot of debugging questions — why a page is cached, what content type is being served, where a redirect points, whether security headers are set — but scanning them as a raw block is slow. This parser breaks them into a readable summary: status, cache behavior, content type, redirects, and security hints.
Surfacing that structure quickly makes problems obvious: a missing cache header, an unexpected redirect chain, an absent security policy. It is a fast first look when a request is not behaving the way you expect.
Private and instant
Parsing happens entirely in your browser — you paste the headers, nothing is fetched or uploaded — so it is safe for headers from internal or authenticated requests.
Frequently Asked Questions
What headers does this parser explain?
It explains common caching, content type, security, redirect, and server headers from pasted HTTP responses.
Does it fetch a URL?
No. Paste headers from curl, DevTools, or a server response.
Is it a security scanner?
No. It is a lightweight parser and checklist, not a full security audit.
Are headers uploaded?
No. Parsing happens locally in your browser.
