HTTP Header Parser
Paste response headers and get a readable breakdown of status, cache behavior, content type, redirects, and security hints.
Make response headers easier to read
Headers control caching, redirects, content type, and browser security behavior, but raw response output is not always easy to scan. This parser turns pasted headers into grouped notes and highlights common fields worth reviewing.
Use it after curl, browser DevTools, CDN changes, or hosting updates to sanity-check how a page is being served.
