What SentinelAC is
SentinelAC is a free anti-cheat project for Minecraft servers running Fabric on version 1.21.6. It is listed for Linux, macOS, and Windows environments. Detection coverage includes movement checks for Speed, Fly, NoFall, Jesus, Step, Timer, and Elytra exploits. Combat checks include KillAura, Reach, AutoClicker, Criticals, and Velocity. World checks cover Scaffold, FastBreak, and InventoryMove, while packet checks include BadPackets. Server operators can configure the response to a detection as no action, kick, ban, or a custom command. Punishments are disabled by default, so an operator must select an enforcement option before detections trigger those actions. SentinelAC does not provide replay analysis. The project is available through GitHub and has a free plan, with Fabric as its stated server platform.
