Packet Sniffer Mod

Packet Sniffer is a client-side Fabric mod for Minecraft that captures and logs all network packets exchanged between the client and server in real time. Built for developers, modders, and anyone curious about what happens under the hood of Minecraft's network protocol, it intercepts both C2S (Client-to-Server) and S2C (Server-to-Client) traffic and outputs human-readable, fully deserialized packet data to the game log.

Packet Sniffer targets Minecraft 1.21.11+ with Fabric Loader and requires no server-side installation. It serves as a lightweight yet powerful diagnostic tool for protocol analysis, mod debugging, and network education.
