Minecraft mod to change the stack size of all items. For Fabric 1.17.x, 1.18.1, 1.18.2, and 1.19!


Stacker Mod Cover Image


This mod has a config that defaults to 64. Change it to be whatever you like (below int_max), but I do not recommend anything too far over 1 Billion (No support will be given for stacks larger than 1,073,741,823).

Requires Stacc API and Cloth Config API. Stacc API is an embedded library, so don't worry about downloading it. I recommend installing with Mod Menu (for in-game access to the configs), but it is not needed to run.


Note: The maximum you can put into a crafting table at once is capped at 1,000 items per slot. This is done to prevent lag. This is increased to 100,000 if installed alongside FastBench for Fabric.


New in 2.0.0! Config can now be edited in-game (with ModMenu installed):

Stacker Config


New config vales are also added in this update, allowing for font size customization.


New in 3.0.0! Configure individual item or tag stack sizes, and a restart is no longer required anymore!


Stacker 3.0.0 Config


Changes are applied on when saving config, but you can also use the /reload command.
