Hybrid anticheat for Minecraft 1.21+ (Java & Bedrock/Geyser)
Combines packet analysis, server-side physics simulation, combat heuristics, Bedrock/Geyser compatibility, replay tools, staff utilities, plugin hiding, and adaptive false-positive filtering.
Designed as a support anticheat for servers already running GrimAC, Vulcan, or similar — filling gaps in Bedrock handling, moderation tooling, and utilities. Can also run standalone.
