Packet Spy
A client-side Fabric mod that lets you inspect Minecraft network packets live through a simple web interface.
PacketSpy is a client-side Fabric mod for viewing the network packets your Minecraft client sends and receives in real time.
Press F12 (can be rebound in settings) in-game to open the local web interface. From there you can search and filter packets, inspect their fields as JSON, sort packet traffic, mute noisy packet types, and export what you're looking at.
It works in both singleplayer and multiplayer and does not need to be installed on the server.
Features
- Live incoming and outgoing packet viewer
- Search and filter by packet type, direction and category
- View packet contents as readable JSON
- Mute packet types you don't care about
- Packet grouping and traffic visualization
- Dark and light themes
- Local web interface
- Optional LAN access if you want to view it from another device
PacketSpy supports Minecraft 1.21–1.21.11 and 26.1–26.3 using Fabric. Make sure to download the jar that matches your Minecraft version.
The web interface runs locally on your computer and LAN access is disabled by default.
