StarAC | Powerful AntiCheat v2

StarAC v2.0.0 — Full engine rebuild​

StarAC has been rebuilt from the ground up for accuracy, performance, and zero false positives. This is the biggest update yet, and the foundation for frequent improvements from here on.

Detection​

• True 3D Reach & Hitbox — eye-to-bounding-box raytracing with dynamic ping scaling
• 10 KillAura modules — rotation validation, angle-snap, click consistency
• AI cross-correlation across 27 micro-checks to eliminate false positives and catch ghost clients
• Crystal/Anchor Aura, AutoTotem and Mace exploit protection (MaceSwap, MaceDelay, fall abuse)
• Movement — Speed/Bhop (block-friction aware), Fly (gravity & air-time), Elytra exploit monitoring

Performance & compatibility​

• Fully asynchronous engine — stable 20 TPS even in massive PvP
• Spigot, Paper, Purpur & Folia
• Supports Minecraft 1.18 to latest (26.x)

Quality of life​

• Zero-false-positive philosophy — uncertain checks alert your staff instead of punishing
• In-game control panel (/sac panel), live player violation profiles, clean chat & Discord alerts
• Cleaner console and a tidy, production-ready config

Free and always improving​

StarAC is free. It continuously learns from real gameplay to detect more with fewer false flags — every future update gets smarter.

Data & privacy​

StarAC sends anonymous operational data and pseudonymized improvement data (no player names, IPs, chat, or raw UUIDs) as a core part of how it works. By downloading and using StarAC you accept our Terms and Privacy Policy.
