Hotbar Auto Fill
Hotbar Auto Fill refills the selected hotbar slot from matching items in the inventory whenever that stack runs out, including food, potions, soups and broken tools.
What it does
When the stack in the selected hotbar slot is used up, dropped, consumed or broken, the mod looks through the inventory for a matching item and moves it into the slot. Food, potions, soups and tools are all handled, and bottles, bowls and buckets can be stacked from similar leftovers where possible.
The mod is a client-side quality-of-life addition for single-player and multiplayer play, and it can protect a tool from breaking before the last use. A held-item total counter sits near the hotbar so players can track how many items remain. Fabric API is required on Fabric, and Mod Menu is an optional companion for changing its options. The mod is published for Fabric, Forge and NeoForge, with 62 release versions 1.7.10 – 26.2, and it is released under the GNU General Public License v3.0 only.
Key features
Automatic hotbar refill
A selected hotbar slot is filled from matching items in the inventory as soon as its stack is depleted.
Consumables and tools
Food, potions, soups and broken tools are replaced from the inventory, so eating or breaking an item does not leave the slot empty.
Stacking leftovers
Bottles, bowls and buckets are combined from similar leftover stacks where the inventory allows it.
Tool protection
An optional setting stops a tool from breaking by warning or pausing use before its durability runs out.
Held-item counter
A total count of the held item appears near the hotbar, showing how many remain across the inventory.

How it compares
Hotbar Refill is a Fabric-only, client-side mod with files for 1.20.1 – 26.3, released under All rights reserved and not open source. Smart Refill is also a Fabric client-side mod, covering 1.21.4 – 1.21.11 under the MIT License. Bottomless Stack works on Fabric, Forge and NeoForge for 1.18 – 26.2, but it runs as a server-required mod with an optional client, so it is installed differently from this one.
