FoxAddition Anti-Cheat vs Grace Anticheat

FoxAddition Anti-Cheat is a free, self-hosted Minecraft server plugin that adds checks alongside another anti-cheat. It supports Spigot, Paper, and Folia, with automatic detection for Folia and traditional Paper or Spigot servers. The Modrinth listing covers Java Edition versions from 1.7.x through 1.21.x and 26.1.x. Listed detections include irregular packets, break aura, bed aura, chest aura, nuker, and invalid movement. Administrators can edit configuration values and disable checks in selected worlds. Available responses include cancelling packets or actions, notifying, kicking, ejecting, and applying a setback or pullback. With GeyserMC it can detect Bedrock players, while Floodgate can control checks by edition. DiscordSRV can send configurable alerts to a chosen channel; optional logs record violations in dated text files. Installation requires placing FoxAddition.jar in the plugins folder and PacketEvents 2.11.0 or newer. The latest listed release is 1.2.3 Beta 2, under an ARR license.

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.
