Potion Stacking
by proxi
Potion Stacking lets every potion type in a Fabric world stack up to 16 per inventory slot, with the stack size configurable.
What it does
Potions take up a lot of inventory space, and this mod changes that by letting all types of potions stack up to 16 in one slot. Modded potions are covered as well, so a stack size applies to potions added by other mods too. The stack size can be changed in the config file, and a separate option turns off the one-second cooldown between throws.
To keep splash and lingering potions balanced, the mod keeps a one-second cooldown between uses, unless the config disables it. The mod is built for Fabric and is released under the MIT License as open source, with files for 1.21 – 26.3 and 1.1.5-26.3 as the latest file for 26.3. Only the server has to run it; players can join with or without it installed, and the server can run without it in the same way.
The author describes the mod as inspired by Stackable Potions by CursedFlames but rebuilt from scratch, not ported, with its own code and assets. A NeoForge port and a Charm compatibility option are listed among the features.

Use cases
Crowded inventories
Players who carry many brewing results can store them in fewer slots.
Modded potion packs
Servers running several potion-adding mods can apply one stack size to all of them.
Who it’s for: Server owners who want a single stack size across all potions, and players who carry large numbers of brewed potions.
How it compares
Stackable Potions is open source under the MIT License, runs on Fabric and NeoForge for 1.21 – 26.1, and is client and server. Potion Stacking runs on Fabric only, and either side can run it without the other. Stacking Potion is needed on the server, with the client optional as well, but covers Fabric, Forge, NeoForge and Quilt for 1.21 – 26.2 and is not open source.

What the author says
Potions take up WAY too much space in the inventory. With this mod, all types of potions will stack up to 16! Modded potions are also supported:) To keep splash and lingering potions balanced, there is now a 1 second cooldown between uses.
