GK AntiCheat vs Polar Anticheat

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.

Polar Anticheat is cheat-prevention software for Minecraft servers, with checks largely processed in Polar Cloud. It monitors player activity and can mitigate movement, reach, and damage before applying punishments. Listed detection coverage includes auto clicker, heuristics, invalid protocol, movement, tick speed, inventory, world interaction, and latency abuse; enforcement can include hit cancellation, setbacks, kicks, and bans. Its plans include all checks, with limits on players, server instances, and HWIDs. Small server is €15 a month (billed €45/quarter or €150/year); Medium server is €29 a month (billed €29/month or €290/year); Large server is €59 a month (billed €59/month or €590/year). Installation uses a PolarLoader.jar file in the server’s plugins folder. Requirements include Java 8 or higher, Spigot or Paper, and an uninterrupted internet connection. Domain verification is required for onboarding, and proxy plugins are unsupported. The documentation describes an API for server and user lookup, events, and custom subcommands. The service supports Bedrock exemption when Floodgate and player-data forwarding are configured.
