What Grace Anticheat is
Grace Anticheat is a free, self-hosted anticheat for Java Minecraft servers. It targets closet and ghost cheating as well as blatant hacking, using rules and statistical analysis of player behavior. Servers can install it as a Velocity plugin with a Paper companion plugin, or choose a standalone Paper plugin that works 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 Paper for Minecraft Java Edition 1.19.x, 1.20.x, and 1.21.x. Grace can alert staff in-game and send formatted messages to a Discord channel through a webhook. Configuration can teleport players back on hard alerts, kick them on action alerts, and optionally ban them automatically, with automatic bans off by default. Staff commands provide engine status, player evidence summaries, alert controls, violation history, and configuration reloads. Grace is beta 0.1.0 and in active development. Its API, event pipeline, data model, and companion plugin are open source, while detection logic, model weights, and threshold tuning are closed source.
