Plugin ProbablyBackpacks

ProbablyBackpacks, expandable storage for Minecraft servers

ProbablyBackpacks is a Java plugin for Bukkit, Paper, Purpur, and Spigot that adds a tiered backpack system to a Minecraft server. Players progress from Leather to Copper, Iron, Gold, Diamond, and Netherite backpacks, with storage ranging from 27 to 120 slots and extra upgrade spaces.

As a CuriosPaper addon, it equips backpacks in an accessory slot and displays them as visible 3D models. Upgrades can provide crafting, item pickup, magnet, feeding, refill, compacting, tool swapping, and larger stacks, while dyeing adds customization. At BoxToPlay, we see it as a practical way to make exploration and resource management more comfortable.
