Backpack Plugin

🎒 BackPack Plugin
Portable • Persistent • Fully Configurable

📦 Overview

The BackPack Plugin adds personal, portable storage to your Minecraft server.
Each backpack works like a chest, is bound to its owner, and persists across server restarts.

Backpacks are uniquely linked to a player via UUID, protected against nesting exploits, and fully configurable to match your server’s style and balance.

Whether you want simple extra storage or a highly customized backpack system — this plugin has you covered.
