AntiGuard vs Grace Anticheat

AntiGuard is a free anti-cheat plugin for Minecraft Paper and Purpur servers. Its checks cover Fly, Speed, Reach, NoSwing, KillAura, AutoClick, NoFall, and FastBreak, with flag, kick, and ban actions. An embedded web dashboard displays flags, bans, and kicks and lets administrators adjust detection settings live. The REST API exposes statistics, flags, bans, kicks, and configuration endpoints; write operations require an API token if one has been set. AntiGuard can use storage configured for LuckPerms and records data in tables prefixed with `antiguard_`. Documented database options are SQLite, H2, MySQL, MariaDB, and PostgreSQL, with bundled SQLite used if LuckPerms storage cannot safely be reused. Installation is a single JAR copied into the server’s `plugins/` folder, followed by a restart. The guide specifies Paper or Purpur 1.20.x and Java 17. The project calls itself an MVP, and its maker recommends adjusting thresholds or check tolerances if legitimate players are flagged.

Grace Anticheat is a free, self-hosted anticheat for Java Minecraft servers. It targets closet cheating, ghost cheating and blatant hacking through rules-based detection and statistical analysis of player behavior. Servers can run a proxy arrangement with a Velocity plugin and Paper companion plugin, or choose a standalone Paper plugin without Velocity. The proxy setup requires Velocity 3.3.0 or later, Paper 1.19 or later and Java 21 or later; the standalone listing covers Minecraft Java 1.19.x, 1.20.x and 1.21.x. Grace can alert staff in-game and send formatted Discord webhook embeds. Configuration supports teleporting players back on hard alerts, kicking on action alerts and optional automatic bans, disabled by default. Staff commands expose engine status, evidence summaries, alert controls, violation history and configuration reloads. Grace is beta 0.1.0 and actively developed. Its API and related components are open source, while detection logic, model weights and threshold tuning are closed source.
