GolfIV
by samolego
GolfIV is a server-side anti-exploit mod that blocks common client hacks by filtering the data the server sends to players.
What it does
GolfIV stops players with modified clients from using several well-known cheats. It prevents hitting or chatting while a GUI is open, blocks interaction with survival items in creative, and removes creative-only NBT data that enables block picking. It also strips coordinates from player teleport packets and health data from entity packets, so hacked clients cannot read them.
Equipment information is filtered as well, so enchantments and stack sizes are hidden from players with hacked clients. Durability for opponents is withheld, sound events are faked, and incompatible enchantments are removed while stack sizes are reset. Together these measures make lightning-bolt tracking and similar information leaks harder to use.
Only the server needs it, and players join without installing anything. The mod runs on Fabric and Quilt for 1.16.5 – 1.19.4, and its files for 1.19.4 are dated 2023-03-29. It is open source under the MIT License, and snapshot builds are published.
Key features
Open GUI protection
Hitting and chatting are blocked while a container or menu screen is open, closing a common exploit window.
Creative item and NBT filtering
Survival items cannot be taken by clicking in creative, and creative-only NBT data that allows block picking is removed.
Packet filtering
Coordinates in player teleport packets and health data in entity packets are removed before they reach clients.
Equipment and enchantment hiding
Enchantments and stack sizes are hidden from clients that have been modified to read them.
Fake sound and position data
Sound events are faked so that the position of a lightning strike or similar event cannot be pinned down.

Use cases
Hardening a public server
Server owners can add GolfIV to limit cheats that rely on reading coordinates, health or equipment from the network.
Who it’s for: Server owners who run multiplayer worlds and want to reduce the value of client-side hacks. Players do not need the mod on their own computer.
How it compares
Extra Secure Chat is also server-side only and is for Fabric and Quilt on 1.19.1, but its license is All rights reserved and it is not open source. Packet Logger is client-side only and open source under the MIT License, covering 1.16.2 – 1.18.2 on Fabric. AntiDrop is a client and server mod under the Apache License 2.0 with a wider range, 1.14 – 26.3, for Fabric only.
