Restricted Inventory
by CoolerProMC
Restricted Inventory lets server owners and players lock individual inventory slots so that only chosen items or item tags can be placed in them.
What it does
Each player inventory slot from 0 to 35 can be limited to one specific item or to an entire item tag, such as all torches. Rules live in a plain JSON file, and a config screen in the game also edits them. A locked slot shows a ghost preview of the item it accepts, so a player can see what belongs there at a glance. Items picked up from the world are routed to their designated slots first before filling the unrestricted ones.
Two modes control who the rules apply to. In server-wide mode, only operators at permission level 4 can open the config screen, and the same rules apply to every player. In per-client mode, each player sets their own restrictions in a local config screen, which suits players who want a dedicated slot for a sword or a stack of torches. Commands use the restrictedinventory prefix. The mod is open source under the MIT License and is published for Fabric, Forge and NeoForge, with files for 1.20.1, 1.21.1, 1.21.11, 26.1.2, 26.2 and 26.3.
Key features
Item and tag restrictions
A slot can accept one specific item or every item in a tag, and both kinds of rule can be combined in the same config.
Ghost preview of allowed items
Locked slots display a faded preview of the item they accept, so the intended layout stays visible.
Slot index overlay
Holding Tab in the inventory screen reveals the number of each slot, which makes writing rules by index simpler.
Smart item routing
Picked-up items go to their designated slots before filling any unrestricted ones.
In-game config screen
An Items tab lists registered items with their registry IDs on hover, and clicking an item selects it for a slot rule.

How it compares
Only TP is a Fabric, Forge and NeoForge mod for 1.18.2 – 26.3, with the client and server environment and the MIT License, so it covers a different part of inventory use. Better Slots is client-side only, open source under the MIT License, and covers 1.20.1 – 26.3 on Fabric, Forge, NeoForge and Quilt, so players can use it without the server installing anything. Neo Favorite Items targets only 1.21.1 and is client required with the server optional, under the GNU Lesser General Public License v3.0 or later.
