Blarion AntiCheat is a powerful anti-cheat behavior pack for Minecraft Bedrock Edition, built on the ScriptAPI (Beta). Originally derived from Scythe AntiCheat, it has since evolved into an almost entirely independent codebase with extensive custom detection modules. Developed by NyaCrasin under the StarBloom team, Blarion is designed to protect multiplayer worlds from a wide range of exploits, hacked clients, and unfair advantages — all without requiring a dedicated server backend.

🛡️ 40+ Detection Modules — covering combat, movement, inventory, packets, and more

⚡ Real-time Checks — instant flagging with configurable thresholds

🔧 Developer-friendly API — external integration via /flag command for WebSocket / proxy tools

🌐 Multi-language Support — in-game language switching with /blaclang

📋 Admin Commands — inventory inspection, player scanning, forced kicks, and more

🎯 Bypass & Whitelist — per-player tags or config-based exemptions

Import the AntiCheat behavior pack into your world.

Enable "Beta APIs" in World Settings → Experiments.

Ensure the pack version matches your Minecraft version.

Start a multiplayer session and enjoy a cleaner gameplay experience!
