About this Mod

Stackable

Stackable is a mod that increases all block stacking limits to any value less than 127 for Minecraft 1.19.2-1.20.4 and 2.147B in 1.20.6+.

Why 127?

Effectively, I'm lazy, but in reality, Minecraft stores all items with a single signed byte which for our purposes only can be between -128 to 127, since negative values are invalid that leaves a maximum stack size of 127. Moreover, this mod is intended to be compatible with other mods which may also use signed bytes to store items.

Why make this mod

I don't know, other mods already exist that allow for stack sizes above 127. This was more for experimentation with creating mixins and understanding Minecrafts code a little better.

Will you update to X?

Maybe.

Will you backport to X?

Eh, not really.

There's a bug here?

I might fix bugs that are Vanilla specific, but mod compatibility is gonna be kinda hard to do

Mod support?

This mod should be compatible with most other mods, I've tested this mod in all of Fabric Orion, and it generally works, some blocks will limit their storage size to 64 but shouldn't crash. Most of my mixins to the code surround editing the interface that all inventory mods should implement to begin with, so if they call the stack size from that interface they should receive the appropriate value.

Frequently Asked Questions

Stackable 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 (26.3). You can switch loaders with one click in the panel.

Is Stackable compatible with fabric and forge and neoforge?

Stackable officially supports fabric, forge, neoforge for Minecraft 26.3, 26.2, 26.1.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Stackable – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Stackable 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.
