Welcome to the official Smart Backpacks guide!
Smart Backpacks adds expandable backpacks, powerful upgrades, portable workstations, storage networks, automation tools, mob backpacks, and much more.
This page explains the currently registered Smart Backpacks items and their main functionality across the current Forge 1.20.1, NeoForge 1.21.1, Fabric 26.2, and NeoForge 26.2 projects.
