Ghost Anticheat | Java/Bedrock checks
GhostAC
Hybrid simulation anticheat for modern Minecraft servers. Java and Bedrock, with GrimAC support.
GhostAC works standalone or alongside other anticheats, automatically integrating with GrimAC's API and disabling its own movement simulation to avoid conflicts and save server resources, while handling combat, Bedrock checks, and heuristics.
Features
- Simulation-based movement: Server-side movement prediction.
- Advanced combat detection: Statistical aim analysis, aim window hit validation, entity occlusion, packet-level criticals.
- Java and Bedrock/Geyser checks: Dedicated checks for both.
- GrimAC companion mode: When GrimAC is detected, GhostAC disables its own movement engine and leaves movement detection to GrimAC. Combat, packet, Bedrock, and heuristic checks stay active.
- Visual replays: Review GhostAC flags, GrimAC flags, or both.
- Configurable setback: Manage setback settings directly from the GUI.
- TPS-adaptive detection: Reduces false positives during lag.
- Folia support.
