Our verdict on VoidAC
VoidAC is an open-source Minecraft anti-cheat plugin for Paper 1.16.5 and compatible forks. It is aimed at solo administrators and small server teams that need more than basic flagging, particularly when reviewing suspected combat cheats or unusual player behavior. Its coverage includes KillAura checks based on CPS, reach, aim deviation, and through-wall hits, along with trajectory analysis, snap aiming, grid alignment, noise, lock-on behavior, packet abuse, NBT manipulation, VPNs, and X-ray. The plugin is installed directly on a Minecraft server and is available under the MIT license.
Evidence and enforcement are the clearest reasons to consider VoidAC. Player profiling creates per-player baselines and identifies anomalies, while confidence-based thresholds support decay, spike detection, alerts, automatic bans, manual bans, freezes, spectating, reports, and evidence logging. The rolling 20-second replay recorder can save and load JSON data for administrator playback, giving staff a way to review incidents rather than relying only on individual alerts. Anti-Xray protection hides ores behind walls, extending coverage beyond combat behavior.
Its ecosystem fit is practical for servers already using common Minecraft administration tools. VoidAC lists integrations with GrimAC, PacketEvents, PlaceholderAPI, Discord, MySQL, SQLite, Bungee, and Velocity, including cross-server synchronization through Bungee and Velocity. Discord bot and webhook support can connect detections to existing moderation workflows, while MySQL and SQLite provide database options. The trade-off is platform scope: published support centers on Paper 1.16.5 and compatible forks. Servers running other Minecraft versions, or teams seeking a hosted service instead of self-hosted administration, should choose an alternative. For free Paper 1.16.5 servers that prioritize configurable detection and reviewable evidence, VoidAC is a focused fit.
