Stackable Potions
by Prunty
Stackable Potions lets each potion type hold sixteen per slot instead of one, for Fabric servers on 1.21 – 1.21.11.
What it does
Vanilla potions occupy a full inventory slot each, which makes carrying a supply for fights or raids costly and fills chests quickly during brewing. Stackable Potions changes the stack size of all three potion types to 16, so one slot holds sixteen potions of the same kind.
The mod is server-side only, so players join without installing anything and the server applies the change for everyone. It is published for Fabric alone, with builds covering twelve release versions. The latest file is 1.0.0+mc1.21.11 for 1.21.11, released 2026-02-08. The code is under the MIT License, and the mod is not open source.
Key features
Regular potions stack to 16
Healing, swiftness and other regular potions group into stacks of sixteen in the inventory.
Splash potions stack to 16
Thrown potions use the same stack size, so a combat supply takes up far less room.
Lingering potions stack to 16
Lingering potions are stacked alongside the other two types, which keeps storage rooms tidier.
Less chest clutter
Potions take fewer slots, so brewing output no longer floods a chest with single items.

Use cases
Raid and combat preparation
A player can carry several healing and splash potions for a raid without filling the hotbar and backpack with single items.
Storage and brewing setups
Brewing stations that produce large batches fill fewer chest slots, so storage rooms stay manageable.
Who it’s for: Server owners who want a Vanilla+ style pack with less inventory friction, and players who brew in quantity or prepare for long adventures on a Fabric server.
How it compares
PotionsButStackable is a Fabric mod for 1.21.11 that needs client and server installs, and its license is All rights reserved, so it is not open source. Potions As They Should Be covers 1.21.1 on Fabric and NeoForge, needs both client and server, and is open source under the GNU Lesser General Public License v3.0 only. Stackable Potions instead runs server-side only, so players need nothing on their side.

What the author says
Vanilla potion stacks are annoying. This fixes that. Stackable Potions Plus makes regular, splash, and lingering potions stack to 16 instead of 1, which means less inventory clutter and less chest spam during brewing, raiding, and combat prep.
