NoCheatPlus
What it is
NoCheatPlus is a free, GPL-3.0 anti-cheat plugin for administrators running Minecraft Bukkit, Spigot, or CraftBukkit servers. It aims to enforce vanilla mechanics and prevent abuse of Minecraft or its protocol. Checks cover movement, combat, block breaking and placing, inventory behavior, chat and command spam, and other malicious activity. Movement checks address flying, speed, excessive packets, fall damage, no-clipping, and vehicle movement. Fight checks include fake critical hits, out-of-reach attacks, excessive hit rates, and invulnerability. Administrators can configure checks and use responses such as cancellation, logging, server commands, bans, kicks, or denying login. The project documents API hooks for other plugins, including exemptions and violation processing. Installation requires placing the JAR in the server’s plugins folder and starting a supported server. ProtocolLib is required for network checks such as attack-frequency monitoring, and an unsupported version can disable some checks. Listed Minecraft versions range from 1.7.10 through 1.12.2.
