MultiPlayerInvSync is different.
It doesn't just "watch" the inventory. It hooks directly into the server internals (NMS + Netty) to handle inventory packets instantly.
It is built for modern servers (Paper/Folia 1.21+) that need performance and correctness.

⚡ CORE FEATURES
- Packet-Level Sync
No polling. No schedulers. When you move an item, it moves for everyone. Instantly.
- Hardcore Death Logic (Anti-Dupe)
When one player dies, the inventory drops once. Every synced player loses their items immediately. No "logging out to save items." No duplication glitches.
- Total State Synchronization
We sync everything:
- Main Inventory (36 slots)
- Armor Slots
- Offhand (Shields/Torches)
- Ender Chests
- XP Levels & Progress (Optional)
- Economy Balances (Optional) - Team Support
Works out of the box with BetterTeams.
Don't have teams? It defaults to a Global Inventory (everyone shares one inventory).
