Stackable Items 64
by QXIK_mIJ
Stackable Items 64 raises the maximum stack size of items that Minecraft normally limits, such as enchanted books, totems and potions.
What it does
Each item category has its own stack size value, set in a JSON configuration file or changed in-game with commands. Changes take effect immediately and are saved to the file without restarting the server. Custom values can also be set for any vanilla or modded item by its Registry ID.
Only completely identical items stack together. Stacks never merge when their enchantments, potion effects, durability values, custom names or data components differ. Filled shulker boxes count as empty and follow the empty shulker box setting.
The mod runs on both single-player and dedicated server environments and requires Fabric API on Fabric. It is published for Fabric, Forge and NeoForge, with files for 26.1, 26.2 and 26.3 among the seven release versions covered, 1.21.1 – 26.3.
Key features
Per-category stack sizes
Each category sets its own maximum, so enchanted books, potions and boats can be tuned separately.
Custom items by Registry ID
Any vanilla or modded item can receive a custom stack size by listing its Registry ID in the configuration.
In-game commands
Stack sizes can be changed with commands during play, and the changes are written to the configuration file.
Identical-only stacking
Only items with the same enchantments, effects, names and data components merge, so distinct items keep their own identity.

How it compares
Bigger Stack Size is open source under the MIT License, works on Fabric, Forge, NeoForge and Quilt for 1.20.1 – 26.3, and is required on the server while clients may leave it out. Stack Size Plus is a Fabric-only option under the MIT License for 1.21.11 – 26.2, and it needs both client and server. Stackable Items 64 is not open source; it is licensed under the Apache License 2.0.
