Packet Logger
by haykam
Packet Logger records the network packets exchanged between a game client and its server, so players and developers can read what was sent and received.
What it does
Once installed, the mod writes a log of packets sent and received during play. Each entry includes the packet's class name and the channel name it travelled on. Packet Logger requires the Fabric mod loader, and only the client needs it, so a server runs without it. The files are published for Fabric across 9 release versions, 1.16.2 – 1.18.2, and the code is open source under the MIT License.
