StackPlus
by RoxyCoding
StackPlus raises the maximum stack size of items from the usual 64 to one billion, and it is a client mod for Fabric and NeoForge.
What it does
Players who carry large quantities of one item can hold up to 1,000,000,000 of it in a single stack, where vanilla Minecraft caps stacks at 64. Huge counts stay readable in the interface through number formatting, which can be turned on or off in the in-game settings.
Per-item rules let a player or pack author set limits for individual items, and the settings screen offers exact values and presets. Damageable equipment such as tools, weapons, armor and shields stays unstackable by default, and the author has made it stackable as an option. The case maximum stack size keeps its default value of 1,000.
The mod is client required and server optional: players need it installed, while the server can run without it. Snapshot builds are published alongside release versions, and non-snapshot versions require Mod Menu. Files are published for Fabric and NeoForge across 17 release versions, 1.21 – 26.3, and the code is released under the MIT License, so it is open source.
