Lithium is a free, open source optimization mod for Minecraft Java Edition, available for Fabric and NeoForge. It improves the game’s internal logic without changing vanilla gameplay, targeting systems such as mob AI, physics, block ticking, and world updates.
Designed for both a Minecraft server and individual play, Lithium can reduce tick times, helping support more entities, chunks, and players while making gameplay feel more responsive. It works on the server or client independently, making it a practical choice for modded environments. At BoxToPlay, we recommend it for smoother and more efficient server performance.
