Barrel Extender
by antarip
Barrel Extender doubles the storage of vanilla barrels on Fabric servers, raising each one from 27 slots to 54.
What it does
Barrel Extender enlarges vanilla barrels from three rows of 27 slots to six rows of 54, so a barrel holds the same amount as a double chest. The block still opens the usual barrel screen, and existing barrel contents stay where they were. The mod works with barrels that are already placed in a world, so a base built earlier does not need to be rebuilt.
The mod is a small utility for survival and multiplayer servers where storage space runs short. It adds no new blocks, recipes, commands or custom user interface, and it does not change how barrels are crafted or placed. Players who join a server running it need nothing installed, since the expanded barrels are handled on the server.
Installation requires Fabric on the server; the mod is published only for Fabric, with 24 release versions covering 1.20 – 26.3. Players who run the game in single-player install it through the mods folder, and the code is covered by the MIT License but is not open source. Before the mod is uninstalled, any items stored in the extra slots should be removed, because vanilla barrels hold only 27.
Key features
Six-row barrels
Each vanilla barrel gains three extra rows, giving 54 slots in place of 27.
Existing barrels kept
Barrels that already exist keep their items, and the extra slots are added to them.
Server-side handling
The expanded storage runs on the server, so multiplayer servers can use it without client installs.
Vanilla block retained
The barrel block and its screen stay as they are, with only the number of slots changed.

How it compares
More Barrel Variants is a Fabric mod for 1.20.1 – 26.3 that adds further barrel variants, is released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, is not open source, and runs on client and server. Obsidian Chest is server-side only for 1.20.1 – 26.3 and is under the All rights reserved license, so it is closed. Barrel Extender differs by keeping the vanilla barrel and only enlarging it, while the other two add new storage blocks.
