BarrelShulkers is a lightweight server-side plugin for Minecraft 1.21.4 that turns vanilla barrels into fully functional shulker boxes.
With this plugin, every barrel placed in the world behaves exactly like a shulker box — it can be broken and picked up while retaining its inventory, renamed in an anvil, and placed down again with all items preserved.
This is perfect for survival servers, mini-game servers, or any multiplayer world where you want shulker-like functionality without needing to go to the End.
Features:
Barrels retain their inventory when broken
Works with hoppers, dispensers, and other redstone components
Supports renaming barrels in an anvil (the custom name appears in the GUI)
No client-side mods required — pure server-side
Lightweight and optimized for 1.21.4
Commands & Permissions: No commands just place and use barrels as shulkers!
