Fluxzy Desktop

HTTP and HTTPS debugging proxy for developers, QA, and security folks. Captures HTTP/1.1, HTTP/2, WebSocket, and gRPC traffic, lets you inspect, modify, and replay it. What sets it apart: 1.Offline. No login. No cloud. Free for personal use, one-time license for pro use, no subscription. 2.Native PCAP capture with embedded TLS keys, opens straight in Wireshark. 3.YAML rule engine shared across desktop, CLI, and Docker. Write once, run anywhere. 4.Tauri-based UI, around 200MB install, not a gigabyte Electron app. 5.40+ actions: mock, breakpoint, inject headers, throttle, spoof DNS, replay sessions.
