Auto Splash Refill
by b1nt1n
Auto Splash Refill keeps the splash potion in the hand topped up, so a player who throws the last one is not left empty-handed mid-fight.
What it does
After each throw, the mod moves a matching splash potion from the rest of the inventory into the hand slot right away. The refill uses the same potion type the player just threw, so a stack of healing or harming potions stays in reach without opening the inventory during a fight. A counter shows how many potions remain in the inventory, so the player can see when the stock is running low.
The mod is built for minigames and PvP, where opening the inventory mid-fight costs time. It is a Fabric mod for Minecraft 1.21.4 only, and it is client-side only, so the server does not need it and players can join a server without installing it. Files are published for 1.21.4 alone, and the code is released under the MIT License, which does not make it open source.

Light footprint
The author describes the mod as lightweight and performance-friendly, adding only the refill step after each throw.

How it compares
Smart Refill is a Fabric mod for 1.21.4 – 1.21.11 under the MIT License, and it is not open source. Automatic Potion Restocker is also Fabric and client-side only, released under the MIT License, but its files cover 1.21 – 1.21.11. Auto Splash Refill only targets 1.21.4, which is the narrowest range of the three.
