FoxAddition Anti-Cheat vs GK 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.

GK AntiCheat is a Minecraft server plugin that checks players to deter hacked clients from entering a server. Its listed verification flow asks a player to send a random code using a .say command supplied through tellraw. Administration commands cover help, configuration reloads, whitelist changes, and player-record checks. Detection targets include hacked clients and spamming bots, with kicking, automatic bans, and whitelist exclusion listed as enforcement actions; automatic bot kicking is still being tested. The plugin is listed for Spigot and tested on Minecraft versions 1.8 through 1.16, though its native major version is Legacy, below 1.13. Configuration languages include German and Chinese, and compatibility is listed with SkillAPI, other skill plugins, and other anti-cheat plugins. The author says it is mainly for Kit PvP or SkillAPI servers and recommends pairing it with another anti-cheat for survival servers. It has a free plan and paid access from $4.99 one-time. The author also warns that some hacked clients can bypass it and that update time is limited.
