FoxAddition Anti-Cheat vs GuardAC

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.

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.
