moreStackable
by maevius
moreStackable raises the stack size of most items, potions and blocks, so players can carry larger quantities in one slot.
What it does
The mod raises the maximum stack size of nearly every mineable block and many potions, pearls, banners and items to a higher limit. Doors, traps, tables and other blocks outside the mineable set are covered too. A small number of items keep the default stack size of 64, and the mod leaves them unchanged.
moreStackable is server-side only, so the server runs it and players join without installing anything. It is a Fabric mod for 1.21 – 1.21.11, with the latest file 0.7.0 for 1.21.11, published on 2025-08-21. It requires Item Components, and the code is released under the MIT License, though it is not open source. The author links an issue tracker for reports about missing blocks.
Key features
Larger stacks for blocks
Nearly every mineable block gets a stack size of 99 instead of the vanilla value.
Potions, pearls and banners
Many potions, ender pearls and banners stack higher, and their stack size is doubled.
Doors, traps and tables
Doors, traps, tables and similar blocks are included in the stack size changes.
Unchanged items
Some items remain at 64, so the changes apply selectively rather than to the whole item list.

Use cases
Storage-heavy survival
Players who keep large amounts of building blocks can free inventory slots without sorting chests as often.
Multiplayer servers
A server owner can install the mod alone, and players keep their clients vanilla while the larger stacks apply.
Who it’s for: Survival players who carry many blocks, and server owners who want fewer full inventories without changing the client.
How it compares
Stack Size Modifier is a Fabric mod for 1.21.7 that needs both the client and the server, and it is not open source under the MIT License. SG Stackables is client-side only and open source under the MIT License for 1.21.3 – 1.21.8. FatStack is server-side only like moreStackable, but it is open source under the Mozilla Public License 2.0 and covers only 1.21.9 – 1.21.10.
