PRAXIC AntiCheat

Server-side anticheat for Fabric 1.21.1

No client mod required. One jar. Every check enabled by default.

⚡ 18 Detection Modules

Movement Combat World Client ⚡ Fly 🗡️ Reach 🧱 Scaffold 🖱️ AutoClicker 🔮 Y-Prediction 🌀 KillAura ⛏️ FastBreak 🧿 AutoTotem 🏃 Speed 💥 Velocity 🪂 NoFall 🎒 Inventory 🌊 Jesus ⏱️ Timer

Each check runs independently. Own sensitivity, own cooldown, own response action. Toggle on or off. One config file.

🔮 Smart Engine

🧠 Physics Prediction — Simulates vanilla gravity tick by tick. Compares predicted position to actual. Catches fly and hover that threshold checks miss.

🌐 Lag Compensation — Thresholds scale with each player's latency. No configuration needed.

🔄 Violation Decay — VL decreases over time without new flags. Clean players recover on their own.

↩️ Setback — Silent teleport to last safe position instead of disconnect.

⚙️ Actions

Every check carries its own configurable response:

Action Behavior ⚠️ Warn Alert the player, log the violation 🚪 Kick Immediate disconnect 🔨 Ban Permanent, automatic ↩️ Setback Silent teleport to last safe position
