Stacker
If you have ever found yourself frustrated by the 64-item limit in Minecraft, you are not alone. Managing massive builds, sorting through double chests, or simply trying to carry enough blocks for a large project can be a chore. The Stacker mod solves this problem by letting you change the stack size of every item in the game. Instead of fiddling with shulker boxes or making countless trips back to your base, you can set a stack size that fits your playstyle, whether that is a modest 256 or a jaw-dropping 1 billion.
What Does Stacker Do?
Stacker is a lightweight Fabric mod that overrides the default stack limit for all items. The mod comes with a config file that defaults to the vanilla 64, but you can change it to any value below the integer maximum. The developer recommends staying under 1 billion (1,073,741,823) for stability, but the choice is yours. This flexibility makes Stacker perfect for creative mode players, server admins, and anyone who wants to streamline their survival gameplay.
Beyond the global stack size, version 3.0.0 introduced the ability to configure individual item or tag stack sizes. This means you can keep ender pearls at 16 while letting cobblestone stack into the thousands. The changes apply instantly when you save the config, and you can also use the /reload command to refresh everything without restarting the game.
Key Features and Compatibility
Stacker is built for Fabric and supports Minecraft versions 1.17.x, 1.18.1, 1.18.2, and 1.19. The mod requires the Stacc API, which is embedded directly into the download, so you do not need to install it separately. You will also need the Cloth Config API to access the configuration menu. For the best experience, the developer recommends installing Mod Menu, which gives you an in-game interface for editing your stack sizes without touching text files.
- Change the stack size of all items globally.
- Set custom stack sizes for individual items or tags (version 3.0.0+).
- Edit configs in-game with Mod Menu installed.
- Customize the font size of the config interface.
- No restart required after changing values.
- Works with FastBench to allow up to 100,000 items per crafting slot.
Understanding the Crafting Limit
One important note is that the maximum number of items you can place into a crafting table slot is capped at 1,000. This is a deliberate safety measure to prevent lag from massive crafting operations. If you install FastBench for Fabric, this cap increases to 100,000 items per slot, which pairs beautifully with Stacker for bulk crafting projects.
How to Install Stacker
Learning how to install Stacker is straightforward. First, ensure you have the correct Fabric Loader installed for your Minecraft version. Download the Stacker mod file from a trusted source like CurseForge, GitHub, or Modrinth, and place it into your mods folder. Do not forget to add the Cloth Config API and optionally Mod Menu to the same folder. Once you launch the game, the mod will be active, and you can adjust the stack size through the config file or the Mod Menu interface.
For players who prefer a more streamlined setup, the foxygame.net launcher offers a one-click install for Stacker, pulling the correct version for your Minecraft client and managing the required dependencies automatically. This approach eliminates the hassle of manually tracking down API files and ensures you always have a compatible setup.
Where to Download Stacker
When you are ready to download Stacker, always stick to the official sources listed by the developer: CurseForge, GitHub, or Modrinth. These platforms host vetted files, whereas third-party sites can distribute modified or malicious versions. The mod is free to use, and the developer regularly updates it to support new Minecraft versions and improve functionality.
If you are using the foxygame.net launcher, you can find Stacker in the add-on catalog, which also handles version compatibility checks before installation. This is especially useful if you play on multiple Minecraft versions, as the launcher will match the correct Stacker build to your game profile without manual intervention.
Alternatives for Other Mod Loaders
Stacker is exclusively for Fabric. If you play on Forge or Rift, the developer points you to other projects: Stacc for Fabric 1.15.2 and 1.16.5, StackUp for Forge and Rift on 1.12.2 and 1.13, and Bigger Stacks for Forge on 1.18.2 and 1.19. These are separate projects, so any issues with them should be reported to their respective authors.

Whether you are a builder moving thousands of blocks, a redstone engineer testing massive contraptions, or a server admin looking to tweak gameplay, the mod gives you total control over stack sizes. The in-game config editing and instant application make it user-friendly, and the lack of a restart requirement means you can experiment freely.
