Stack Unlimited

By default, common stackable items like blocks, food, ingots, materials, and other normal resources can stack up to 999. The limit is configurable, with a hard cap to help prevent broken inventories, crashes, or unsafe item counts.

The mod is designed to be safe for survival worlds, multiplayer servers, and long-term saves. It keeps unsafe items at their normal vanilla stack sizes, including tools, weapons, armor, elytra, tridents, bows, crossbows, shulker boxes, bundles, potions, books, maps, spawn eggs, filled buckets, damageable items, and items with custom data.

Large stack counts are also displayed cleanly in the UI. Instead of long numbers overflowing the item slot, the mod shows compact counts like 12K, 12.4K, or 2.4M. You can still see the exact amount by hovering over the item.

This mod is meant for players who want less inventory clutter without turning Minecraft into a broken or unsafe mess. It gives you larger stacks while still keeping important safety limits in place.

Important:
Do not remove the mod while your world or inventory contains stacks above vanilla limits. Split large stacks back down first to avoid vanilla Minecraft handling them incorrectly.
