AntiGuard vs Nimbus AntiCheat

AntiGuard is a free anti-cheat plugin for Minecraft Paper and Purpur servers. Its checks cover Fly, Speed, Reach, NoSwing, KillAura, AutoClick, NoFall, and FastBreak, with flag, kick, and ban actions. An embedded web dashboard displays flags, bans, and kicks and lets administrators adjust detection settings live. The REST API exposes statistics, flags, bans, kicks, and configuration endpoints; write operations require an API token if one has been set. AntiGuard can use storage configured for LuckPerms and records data in tables prefixed with `antiguard_`. Documented database options are SQLite, H2, MySQL, MariaDB, and PostgreSQL, with bundled SQLite used if LuckPerms storage cannot safely be reused. Installation is a single JAR copied into the server’s `plugins/` folder, followed by a restart. The guide specifies Paper or Purpur 1.20.x and Java 17. The project calls itself an MVP, and its maker recommends adjusting thresholds or check tolerances if legitimate players are flagged.

Nimbus AntiCheat is a free plugin for detecting cheats on Minecraft servers. Its movement prediction and packet inspection power 43 individually configurable checks across movement, combat, world, packet, and inventory categories. The checks account for conditions such as latency, server lag, movement buffs, teleports, knockback, flight toggles, and join grace. Detection and staff alerts are enabled by default; operators configure punishments before they are used. Available actions include configurable commands, kicks, temporary or permanent bans, freezes, setbacks, and cancellation of illegal actions. Staff tools include player reports, an inspection GUI, in-game check controls, violation logs, and commands for testing alerts and punishments. PacketEvents is required; PlaceholderAPI, Discord webhooks, Citizens, LiteBans, and a permissions plugin are optional integrations. Nimbus requires Java 21 and targets Paper 1.21.x; it was built and tested against Paper 1.21.8, while other 1.21.x builds are untested. It supports Java-edition players, not Bedrock or Geyser players.
