In their own words
GuardAC
GuardAC is a cloud anti-cheat for Minecraft servers that looks for KillAura, aim assist, and unusual combat crosshair movement. It runs server-side, so players install nothing. During fights, the plugin sends a short set of crosshair-movement numbers to the cloud rather than video. The system learns a player's usual mouse movement and can flag changes in that style during a session. Staff receive alerts with a player name and score, and can handle punishment manually or automate it. Configurable thresholds range from alert-only operation to automatic bans. Listed enforcement actions include logs, kicks, bans, broadcasts, console commands, and optional combat suppression; replay analysis is also listed. The plugin supports Paper, Spigot, Purpur, and Folia servers running Minecraft 1.16 or newer. Supported servers require Java 17 or newer; Minecraft 26.1 and 26.2 require Java 25. The service combines a server plugin with a cloud API accessed using an API key. The free plan is listed at free, and a trial key is issued after sign-up without a card.
