API Response Inspector

Paste a raw HTTP response — status line, headers and body — and read it at a glance. The status is classified, common headers are explained, and JSON, XML, HTML and form payloads are rendered clearly. Everything runs in your browser.

Raw HTTP response

stays on this page

Paste what curl -i or your network tab gives you: the HTTP/1.1 200 OK status line, the headers, a blank line, then the body. Headers-only pastes also work.

How it works

The paste is parsed in your browser: the optional status line, then header lines up to the first blank line, then the body. The body format is taken from Content-Type or inferred by inspection, and JSON is pretty-printed, XML is indented, form data becomes a table, and markup is shown as inert source. Nothing is uploaded and no request is made.
