About this Mod

Stacker

Minecraft mod to change the stack size of all items. For Fabric 1.17, 1.18, 1.18.2, and 1.19!

Stacker Mod Cover Image

This mod has a config that defaults to 64. Change it to be whatever you like (below int_max), but I do not recommend anything too far over 1 Billion (No support will be given for stacks larger than 1,073,741,823).

Requires Stacc API and Cloth Config API. Stacc API is an embedded library, so don't worry about downloading it. I recommend installing with Mod Menu (for in-game access to the configs), but it is not needed to run.

Frequently Asked Questions

Stacker server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.19.4). You can switch loaders with one click in the panel.

Is Stacker compatible with fabric and quilt?

Stacker officially supports fabric, quilt for Minecraft 1.19.4, 1.19.3, 1.19.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Stacker – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Stacker consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
