Themis Anti Cheat is a free plugin that protects your Minecraft server from common cheats while staying light on performance. It focuses on accurate movement and combat detection, blocking hacks like fly, speed, reach and various Bedrock specific exploits without flooding staff with false alerts. Compatible with modern Paper and Spigot versions from Minecraft 1.17 to 1.21, it supports Geyser and Floodgate setups, adapting checks for Bedrock players.
At BoxToPlay, we recommend Themis to server owners who want efficient, configurable protection that keeps survival, SMP or mini game worlds fair and enjoyable for every player.
