Random Supply Box
by FrostPierce
Random Supply Box, a Fabric mod for Minecraft 1.21.1, makes indestructible loot boxes appear at random places across the world.
What it does
Boxes spawn automatically about every 2 minutes, at truly random positions within a wide X and Z range and a Y range that covers almost the full world height. A new box replaces whatever block occupies its spot, and each box vanishes after 10 minutes if no one opens it. Boxes cannot be broken, even by players in Creative mode.
Each box holds between 5 and 20 stacks of random items drawn from a rarity-weighted table, so common items turn up more often and epic items are rare. Some creative-only items, along with bedrock, command blocks, barriers and structure blocks, can appear in the loot. The box uses the vanilla chest texture, which needs to be copied once during installation.
Random Supply Box requires Fabric API. Fabric Loader 0.15.0 or a newer release is needed, along with Fabric API. Servers that run it need every player to install it too. Files cover 1.21.1 – 1.21.11 across 11 release versions, and the latest file is 1.0.0-1.21.1 for 1.21.11, published on 2026-06-05. The mod is released under All rights reserved and is not open source.
Key features
Automatic spawning
A new supply box appears somewhere in the world every 2 minutes, without any command or setup.
Weighted random loot
Each box contains 5 to 20 stacks, with common items more frequent than rare epic items.
Timed disappearance
Boxes vanish after 10 minutes, so each one is a short-lived find that has to be reached in time.
Indestructible boxes
Players cannot break a box, even in Creative mode, which keeps the loot available until it expires.
