by Rinorsi

Bigger Stacks (Unofficial) raises the maximum stack size of nearly every item on NeoForge 1.21.1, with per-item caps set in a config file.

What it does

Global caps are kept in biggerstacks-rules.xml, where the author lets server owners set limits for individual items and override the defaults for groups such as totems, potions and enchanted books. Items that normally cannot stack, including the Totem of Undying, can be made stackable, and custom items can be added through tags. Only the client needs the jar, and the mod is released under the GNU General Public License v3.0 only as open source software. It is a NeoForge 1.21.1 fork and does not target other loaders or versions.

Key features

  1. Higher stack sizes

    Raises the maximum stack size of almost every item, so inventories hold larger quantities per slot.

  2. Per-item caps

    Global caps and one-off overrides for individual items, tags and groups are set in a simple XML rules file.

  3. Unstackable items

    Items that normally cannot stack, such as the Totem of Undying, can be made stackable through config entries.
