Our verdict on AntiCheatX

AntiCheatX is an open-source Minecraft server plugin for Paper 1.21.1 and compatible forks. It is aimed at solo administrators and small server teams that need baseline detection for common cheats without a commercial plan. The plugin analyzes movement, combat, mining, and block-placement behavior, covering fly, speed hacks, X-ray, KillAura, reach, NoFall, timer manipulation, scaffold, and irregular movement. It runs through a self-hosted deployment and requires Java 21 or higher.

Its main strength is breadth within a focused anti-cheat scope. X-ray detection uses mining-pattern and ore-ratio analysis, while movement and combat checks address several common behavior categories. Administrators can configure violation thresholds, use violation-level decay, receive alerts, and write violations to files or the console. Enforcement options include NONE, WARN, KICK, and BAN, allowing server teams to choose whether a detected violation produces an alert, a player-facing response, or no immediate action. Multiverse and Bukkit-compatible permissions plugins are listed as integrations.

AntiCheatX fits servers that can manage a plugin in their own Paper environment and want configurable coverage rather than a hosted service or broader Minecraft version support. Its published compatibility is centered on Paper 1.21.1 and compatible forks, so administrators running other versions should choose a plugin with matching verified support. The documented repository version is 1.0.0, and the project is licensed under MIT. Support channels include tickets, community help, and documentation. Choose AntiCheatX for a small 1.21.1 server seeking core checks and standard punishments; choose an alternative when version coverage beyond 1.21.1 is essential.
