BigStacks is a highly configurable, server-friendly NeoForge mod for Minecraft 1.21.1 that allows you to break the vanilla 64-item stack limit. Raise your stack sizes up to 1,000,000,000 (1 Billion) with extreme precision!
Whether you want a slight bump to 128 for building materials, or a massive 100,000 stack limit for your heavily modded storage systems, BigStacks gives you total control through a beautiful in-game GUI.

/BigStacks (Opens the GUI, view lists, set global limits)./bigstacks (Manage the server configuration, reload the TOML file).Alternatively, you can edit the config/bigstacks-common.toml file directly. The mod will detect changes and update automatically!
BigStacks is designed to be highly compatible. The rendering mixins are superficial and designed to work alongside inventory-sorting mods, JEI/REI, and custom backpack mods without breaking them.
