Mod PacketEvents

PacketEvents, Minecraft Protocol Library

PacketEvents is a protocol library for Minecraft Java Edition, created to help developers process, inspect, modify, and transmit network packets between clients and servers. It is not a content mod that adds blocks or items, but a technical foundation used by server software and other extensions.

Built on Netty, PacketEvents supports platforms such as Paper, Spigot, Velocity, BungeeCord, Fabric, and Sponge. Its portable design, packet wrappers, and event listeners make it useful for creating advanced server features, compatibility tools, security systems, and gameplay enhancements. Our BoxToPlay team recommends it as a powerful behind the scenes component for a modern Minecraft server.
