GuardAC
What it is
GuardAC is a cloud anti-cheat for Minecraft servers that detects KillAura, aim assist, and unusual combat crosshair movement. It works server-side, so players do not need to install anything. During fights, the server plugin sends a short set of crosshair-movement numbers to GuardAC’s cloud rather than video. The system learns a player’s usual mouse movement and flags changes in that style during a session. Staff can receive alerts with a player name and score, then handle punishment manually or configure automated enforcement. Thresholds range from alert-only operation to automatic bans; listed actions include logs, kicks, bans, broadcasts, console commands, and optional combat suppression. The plugin supports Paper, Spigot, Purpur, and Folia servers running Minecraft 1.16 or newer. Supported servers need Java 17 or newer, while Minecraft 26.1 and 26.2 require Java 25. GuardAC consists of a game-server plugin and a cloud API accessed with an API key. A free trial key is issued after sign-up without requiring a card, and the free plan is listed as free.
