How do I install Bundle Tweak?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Bundle Tweak work with?

The listing gives Minecraft 26.1, 26.1.1, 26.1.2, among others. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Bundle Tweak Banner

Bundle Tweak is a Minecraft mod that tweaks one thing about bundles. Items in bundles now always only occupy 1/64th of the bundle, so you can put more 16 stackable items like ender pearls in them, and even unstackable ones like tools! This may feel a bit cheaty, but with Minecraft's awful inventory system it is sometimes hard to organize your inventory well.

Supported versions

Bundle Tweak supports all versions from 1.17 upwards (that's when bundles got added in the code) on Fabric, and from 1.21 upwards also NeoForge. If someome really wants it I can spend time also adding Forge for <1.21, but I have not gotten this request yet.

Here are some screenshots of a bundle with unstackable items in it on different loaders/mc versions:
