Features
The HTTP Header Analyzer helps developers debug APIs and understand HTTP communication. Paste raw HTTP headers from browser DevTools, cURL output, or server logs to instantly parse them into a human-readable format with detailed explanations for each header.
Our tool categorizes headers by type (general, request, response, security, caching, CORS, and more) and provides descriptions for over 70 standard HTTP headers. Special attention is given to security headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
The Security Analysis tab provides a security score based on the presence of recommended headers and highlights potential issues. Missing security headers are listed with explanations, helping you improve your application's security posture. All processing happens locally in your browser.
