Our verdict on AvA Anti-Cheat
AvA Anti-Cheat is an open-source Minecraft Java server plugin for Bukkit-based platforms, intended for administrators of self-hosted servers. It monitors movement behavior such as flying, wall climbing, speed, spider, and phase activity, along with combat logging, auto-clicking, chat spamming, selected packet manipulation, and configurable banned mods. Its operating modes, violation counters, and local detection logging give server administrators control over how detections are handled.
The platform fit is clear for servers running Bukkit, Paper, Purpur, or Spigot on Minecraft 1.21.x. AvA also integrates with Geyser for Bedrock-player ping handling and with bStats. Distributed under the Apache License 2.0, it suits teams that want an open-source plugin they can host within their own Minecraft server setup. Its focus is the Bukkit family rather than a broad multi-platform deployment model.
AvA’s main strength is coverage across several common abuse patterns in one plugin, including movement hacks, combat logging, automation, chat abuse, and banned client modifications. The trade-off is its enforcement scope: the documented actions are kicking players and logging detections locally, without a documented ban action. Packet-manipulation coverage is also selective. Choose AvA if your priority is a free, configurable 1.21.x anti-cheat for a Bukkit-family server with Geyser support. Consider an alternative if you need broader version coverage, more extensive packet checks, or enforcement beyond kicks and local logs.
