LoxyStackTweaks

LoxyStackTweaks is a lightweight Fabric mod that safely improves Minecraft stack sizes without blindly forcing every item to stack.

The mod normalizes vanilla items that are already stackable but limited below 64, such as Ender Pearls, Snowballs, Eggs, Signs and Hanging Signs. Empty buckets can also stack up to 64.

Risky items are protected by default, including filled buckets, durability items, maps, books, bundles, shulker boxes and items with sensitive custom data.

Tools

Shulker boxes
Storage items with custom data
