AntiCheatX
What AntiCheatX is
AntiCheatX is a free, self-hosted anti-cheat plugin for Paper Minecraft servers. It monitors players for flying, speed hacks, X-ray, KillAura and other combat cheats, reach, NoFall, timer manipulation, scaffolding, and irregular movement. Administrators can set detection thresholds and choose NONE, WARN, KICK, or BAN actions, with temporary ban duration configurable in minutes. The plugin sends staff alerts and records violations in the console and a file. Its documentation describes real-time monitoring, sampling, asynchronous processing where possible, and automatic decay of inactive players’ violation levels every five minutes. AntiCheatX requires Minecraft 1.21.1, Paper or a compatible fork, and Java 21 or higher. A Bukkit-compatible permissions plugin is optional, with documented admin and alert permissions defaulting to op. The README lists Multiverse support for world changes and compatibility with Paper-compatible server forks. Installation involves placing AntiCheatX.jar in the server’s plugins directory and configuring plugins/AntiCheatX/config.yml. Chamika Samaraweera is credited as maker, the project uses the MIT License, and support is directed to the issue tracker, discussions, and wiki.
