Extra Inventory
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.
Do you ever get sick of constantly clearing all of the random junk you pick up out of your inventory? Do you wish the inventory were just a bit bigger? Well wish no more, this mod does just that!
This is a Fabric mod that adds more space to players' inventories. Currently, two additional lines are added, as seen in the image. Also, if this mod is on the server, vanilla clients can connect without any issues (though they won't get the extra slots). FABRIC API REQUIRED.
