About HTTP Headers Viewer
Parse raw HTTP request or response headers online and see each name and value in a table, with a short meaning for known fields. This free HTTP headers viewer accepts a status line or request line plus Name: value rows, including folded continuation lines, so a paste from DevTools or a log becomes readable.
Use it to inspect Content-Type, Authorization, Cache-Control, Set-Cookie, CORS Access-Control headers, and custom X-Request-Id values. Support engineers decode a captured response. API developers check whether a gateway added X-Forwarded-For. Security reviews look at Strict-Transport-Security and Content-Security-Policy without loading a full client.
Unknown headers are still listed; they are marked as custom rather than dropped. Invalid lines are reported with a line number so a missing colon is easy to fix. Pair this tool with the HTTP status lookup when the first line is HTTP/1.1 404 Not Found.
Parsing stays in your browser, so cookies and bearer tokens in the paste are not uploaded. Use this free HTTP header parser whenever you need a private table of request or response headers.
