What VoidAC is

VoidAC is a free, multi-module anti-cheat plugin for Paper 1.16.5 Minecraft servers and compatible forks. It checks for KillAura, reach, CPS, aim deviation, through-wall hits, snap aiming, lock-on behavior, player anomalies, packet spam, invalid coordinates, NBT manipulation, X-ray, VPNs, and related behavior. Replay recording and analysis provide evidence for review. The plugin builds a confidence score for each player over time, using configurable thresholds, decay, spike detection, minimum sample sizes, multiple scoring factors, and cooldowns before enforcement. Administrators can issue automatic or manual bans, alerts, freezes, spectating actions, reports, and evidence logging. SQLite is the default database, while MySQL is supported with connection pooling. Integrations include GrimAC, Discord bot and webhooks, Bungee or Velocity synchronization, and optional PacketEvents and PlaceholderAPI. The stated requirements are Paper 1.16.5 or a compatible fork and Java 8 or higher. Installation uses a JAR downloaded from GitHub Releases and placed in the server plugins folder. The project is MIT licensed, with support through GitHub Issues.
