About this project
What does One Billion Stacks add?
One Billion Stacks
One Billion Stacks removes the vanilla stack size limit by increasing the maximum stack size of every stackable item to 1,000,000,000.
Features
- Every item with a maximum stack size greater than 1 now stacks up to 1,000,000,000.
- Large stack counts are displayed in a compact format (e.g.
4.5K,2.3M,1B) to keep inventories readable. - The exact stack count is always shown in the item's tooltip.
- No configuration.
- No commands.
- Just one billion stacks.
Compatibility
This mod modifies Minecraft's stack size system and should work with most mods.
However, mods that hardcode their own stack limits or inventory behavior may require additional compatibility.
FAQ
Does this affect unstackable items?
No. Items with a maximum stack size of 1 remain unstackable.
Can I change the maximum stack size?
No. This mod intentionally has no configuration. Every stackable item always stacks up to 1,000,000,000.
