About this Mod
Overview
LootFilter is a high-performance, lightweight inventory management tool designed for Fabric 1.21.1-1.21.11 Unlike basic loot filters that just toss items away, this mod is built specifically for competitive play and PvP, ensuring your essential gear stays safe while your inventory stays clean of junk.
✨ Key Features
🛡️ Intelligent Inventory Protection:
When you toggle the mod ON, it takes a snapshot of your current inventory. Every item you are currently holding is marked as "Protected" and will never be dropped. The filter only applies to new items picked up after the mod is active.
🌐 Universal Server Compatibility:
Engineered to work on all multiplayer servers(or almost all). It uses specialized packet handling (Sync ID 0) to bypass common anti-cheat restrictions that block inventory interactions while menus are closed.
⚙️ Fully Customizable Keep List:
Use the in-game menu to toggle common gear (Netherite, Diamond, Totems, etc.) or add any specific item name to your custom "Always Keep" list.
⚡ Adjustable Drop Speed:
Fine-tune how fast the mod clears your inventory with a dedicated delay slider to ensure you stay under the radar on high-security servers.
