What xoxo AntiCheat is
xoxo AntiCheat is a free, open-source server plugin for Paper, Bukkit, and Spigot Minecraft servers. It loads 18 checks covering packet anomalies, movement, combat, and block activity. Detected violations can be flagged, while rubberbanding blocks movement, camera rotation, and inventory actions. Multiple violations in one tick are queued for later ticks, with one flag per player per tick. A velocity simulation models player physics to help distinguish legitimate movement and reduce false positives. Administrators can set a threshold for automatic bans and customize readable ban messages. The `/xoxo` command manages exception lists and displays player violations. Installation places a `.jar` file in the server’s `plugins/` folder, and ban history is stored locally. The project uses the MIT license. Listed compatibility spans Paper, Bukkit, and Spigot versions 1.20.5 through 1.21.11; versions 26.1 and 26.1.2 are planned.
