I don't know my version or loader
PotionCoreX
I made PotionCoreX because I wanted a plugin that lets potions stack properly without breaking brewing stands, hopper automation or normal inventory behavior.
After testing a lot of other stackable potion plugins, this is personally the best one for me when the goal is simply to stack potions cleanly and reliably.
Why I made it
A lot of stack plugins can increase stack sizes, but they often do it in a very general way. That can cause annoying problems with brewing stands, hopper automation or potion handling in survival.
I wanted something that focuses specifically on potions and water bottles and handles them in a much cleaner way.
What PotionCoreX does
- makes potions stackable
- supports normal potions, splash potions, lingering potions, water bottles and base brewing potions
- keeps brewing stand potion slots safe
- allows hopper automation without deleting or bugging potions
- keeps vanilla-like inventory behavior in survival
- includes an in-game settings GUI
- lets me create, save, load and delete presets
- supports reloads and automatic config key updates
- includes update notifications for admins
- includes bStats
- supports multiple languages
Main focus
The main focus of PotionCoreX is simple:
make potion stacking work properly without creating brewing bugs, hopper issues or weird inventory behavior.
In-game preview
Stack size settings
Here I can directly change the stack sizes for the different potion categories in the GUI.

Save and apply
This shows how I can save my settings and apply them immediately without restarting the server.

Presets
Here I can save my own preset setup and load it again later with just a few clicks.

Languages
PotionCoreX also supports multiple languages and lets me switch them directly in-game.

For server owners
I made this plugin for server owners who want potion stacking to feel practical, stable and clean instead of hacked together.
If you only want a plugin for stacking potions and want that part to work properly, this is the plugin I would personally use over all the others I tested.
