Instead of Lithium
Lithium alternatives
Lithium is a free mod that improves Minecraft performance across systems such as mob AI, world generation, chunk loading, explosions, and redstone calculations. It works on client and server, and does not require installation on both. Stable optimizations are enabled by default, and players can disable individual patches if compatibility problems arise; changes take effect after a restart. It supports Fabric and NeoForge and says it leaves game mechanics and visuals unchanged.
- 1
Exordium
Free plan LinuxMacWindowsReducing client GUI rendering load — Exordium lowers the GUI’s configurable rendering rate, while Lithium optimizes game systems on both client and server.
- 2
ImmediatelyFast
Free plan Open source APILinuxMac+1Client-side immediate-mode rendering optimization — ImmediatelyFast batches draw calls and optimizes client rendering, while Lithium targets broader game systems on client and server.
- 3
VulkanMod
Free plan Open source LinuxMacWindowsReplacing OpenGL with Vulkan rendering — VulkanMod replaces Minecraft’s OpenGL renderer with a Vulkan engine, unlike Lithium’s optimizations that leave visuals unchanged.
- 4
FerriteCore
Free plan Self-hostedReducing Minecraft RAM use — FerriteCore targets memory use for block states, models, and related data, while Lithium optimizes game performance across other systems.
- 5
Krypton
Free plan Open source LinuxMacSelf-hosted+1Linux-tuned Minecraft networking optimization — Krypton optimizes networking and entity tracking, with features geared toward servers; Lithium covers broader game systems.
- 6
Nvidium
Free plan LinuxNVIDIA GPU terrain rendering with Sodium — Nvidium is a Sodium-dependent rendering backend for qualifying NVIDIA GPUs, unlike Lithium’s client-and-server game-system optimizations.

Alternate Current
Free plan LinuxSelf-hostedReducing redstone calculation lag — Alternate Current optimizes redstone dust calculations and updates, while Lithium addresses redstone alongside many other game systems.

A narrower tool may suit a specific bottleneck better. Exordium and ImmediatelyFast address client rendering, FerriteCore targets RAM use, and Krypton focuses on networking with features geared toward servers. Alternate Current concentrates on redstone calculations. VulkanMod replaces the default renderer and requires Vulkan 1.2 support, while Nvidium depends on Sodium and a qualifying NVIDIA GPU. Before switching, weigh whether you need broader game-system optimization or a targeted change, then check the alternative’s loaders, client or server scope, hardware requirements, and compatibility limits against your setup.
