Infinite Inventory
Every Minecraft player knows the pain of a full inventory. You mine a few stacks of deepslate, pick up some flowers on the way home, and suddenly you are juggling items between chests just to make room. Infinite Inventory takes a different approach. Instead of adding more slots or bigger backpacks, this NeoForge mod gives you a single magical sack with genuinely unlimited storage capacity. It is a bold idea, and it works surprisingly well.
What Makes Infinite Inventory Different
Most storage mods simply expand the number of slots you have. Infinite Inventory goes further by removing the concept of a cap entirely. The mod uses BigInteger internally, which means stack sizes are not limited by normal integer values. You can store as many unique item types as you want, and each stack can grow without a ceiling. Items persist across game sessions, so nothing disappears when you log out.
The sack is not just a bottomless box. It also includes a floating 3x3 crafting grid that you can drag anywhere on screen, and it remembers where you placed it. With JEI installed, you can click the plus button on any recipe and the mod pulls ingredients from both your player inventory and the sack itself. That alone saves an enormous amount of time during long building sessions.
Search, Sort, and Quick Deposit
Finding items in a massive storage system could be a nightmare, but Infinite Inventory handles it with a solid filtering system:
- Item name search: type part of a name to filter the list instantly
- Mod filter: use @modname, such as @minecraft sword
- Tag filter: use #tagname, for example #logs
- Sort modes: cycle between count, mod, and name with the sort button
Depositing items is just as smooth. The Deposit All button moves your entire inventory except the hotbar. Shift-click deposits a single stack, shift-right-click deposits one item, shift-double-click deposits every item of that type, and space plus click deposits everything at once. Once you get used to these shortcuts, going back to manual chest sorting feels unbearable.
Magnet Mode and the Sack Pedestal
Magnet mode automatically pulls items within a six-block range straight into your sack, and the tooltip shows whether it is active. For base automation, place the sack on a Sack Pedestal. Hoppers and item pipes can then insert or extract from any side, turning your sack into a shared storage hub for the whole base. If Curios is installed, you can wear the sack in a charm slot, keep the magnet running, and still open the inventory with the X hotkey from anywhere.
If you would rather skip manual file management, the foxygame.net launcher offers a one-click install path that sets up Infinite Inventory alongside the correct NeoForge build, so you never have to match versions by hand.
Supported Versions and How to Install
Infinite Inventory targets Minecraft 1.21.1 and later on the NeoForge loader, with NeoForge 21.1.77 or newer required. JEI 19.21.0+ and Curios 9.0.0+ are optional but recommended for recipe integration and charm slot support.
Here is how to install it:
- Install NeoForge for Minecraft 1.21.1
- Download Infinite Inventory as a JAR file
- Place the JAR in your mods folder
- Optionally add JEI and Curios for extra features
To craft the sack, arrange eight leather around a chest in a ring shape. The pedestal uses eight stone bricks around a single stone brick in the center. Both recipes are simple enough to craft on your first day.
Final Thoughts
Infinite Inventory for Minecraft is one of those mods that quietly changes how you play. You stop thinking about storage space and start focusing on building, exploring, and automating. The learning curve is gentle, the automation support is solid, and the unlimited stack sizes mean you will never see a full chest again. If inventory management has ever slowed you down, this mod is worth trying.
