Mod Extra Thicc Packets

Extra Thicc Packets, larger network packets for Minecraft

Extra Thicc Packets is a Fabric mod for Minecraft Java Edition that addresses packet size errors during multiplayer sessions. It expands the usual network packet limit, helping clients and servers exchange unusually large amounts of data without disconnections caused by oversized payloads.

It is especially useful with expansive datapacks and content such as Origins, where login or synchronization data can exceed vanilla limits. The mod adds no gameplay features, focusing instead on connection reliability for a modded Minecraft server. At BoxToPlay, we recommend it for packs that need a practical network compatibility layer on both the client and server.
