What it does

Backpacks are crafted as a small backpack first and can be dyed at a crafting table and renamed on an anvil. A Backpack Upgrader enlarges a backpack to 18 slots, and a further upgrade produces the 26-slot version, so one item covers early and late storage needs.

Backpacks go into a dedicated chest slot, so the inventory stays free for other gear. The server needs the mod installed, while players may add it to see the same backpacks on their side. It is published for Fabric, Forge, NeoForge and Quilt, across 20 game versions 1.17 – 1.21.10, and its source code and issue tracker are public, but the mod is not open source and is released under All rights reserved.

Key features

  1. Dyeable backpacks

    Backpacks can be dyed at a crafting table, so players can tell them apart in a shared inventory.

  2. Renamable backpacks

    An anvil lets players give a backpack a custom name, which helps when several are carried at once.

  3. Wearable chest slot

    Backpacks are worn in a dedicated chest slot, keeping them accessible without using the main inventory.

  4. Upgrade path to 26 slots

    A Backpack Upgrader moves a backpack from 9 to 18 slots and then to 26, using crafted upgrade items.
