HTTP Debugger Pro

Professional Windows HTTP sniffer that captures the real traffic from your desktop apps, browsers, and AI agents

See every request and response your app or browser makes. No proxy to configure, no code to change.

HTTP Debugger records traffic from every process on Windows and decrypts SSL, so you can inspect headers, cookies, auth tokens, bodies, and decoded WebSocket, SSE, and gRPC messages as they go over the wire. Modify traffic on the fly, edit and resend a request, save and reload sessions, or export the capture to Excel, XML, JSON, or CSV. Troubleshoot with your AI coding agent through the built-in MCP server.

Special offer from the HTTP Debugger team for ReqBin users — 15% off with code RBIN15

Why browser DevTools aren't enough

Browser tools only see what the browser's own tab sends. HTTP Debugger sees the rest:
  • Desktop apps, console tools, and Windows System Services
  • Local AI coding agents
  • The CORS preflight and the real response headers, even when the browser blocks the response
