HTTP Debugger Pro is a powerful Windows debugging tool for developers, testers, API developers and IT professionals. The tool captures all HTTP and HTTPS traffic of web browsers, desktop applications, command line tools, local servers and other Windows processes. There is no need to change system proxy settings.
HTTP Debugger Pro displays HTTP requests and server responses, including request and response headers, HTTP cookies, etc. The information is presented in a variety of formats including JSON and XML. Real-time communication is supported via WebSocket, Server-Sent Events (SSE) and gRPC messages. In addition to analyzing and re-sending individual HTTP requests, HTTP Debugger Pro allows to modify traffic under test in real time, to filter traffic by specified criteria, to analyze problems affecting performance of your application. Users, who in addition to debugging HTTP traffic also need to monitor other network activity, can look at GlassWire Elite on GetintoWAY.
