Overstack

Tired of filling your inventory with dozens of the same item? Overstack lets you hold way more in one stack — up to 99 million per slot.

What it does:

Bigger stacks — Stack blocks and items far beyond the normal 64 limit
Easy-to-read numbers — Large counts show as 1k, 1.1k, 99M, and so on, so your screen stays clean
Works in normal play — Pick up, drop, place, and use items with huge stacks without the usual headaches
Great for:

Creative builders with huge material counts
Survival players who don’t want 50 chests of cobblestone
Anyone who wants inventory freedom without clutter
Install, play, and stack without limits.
