Developer’s note: A mod that fixes random memory leaks for both the client and server

Memory Leak Fix Minecraft Mod

Memory Leak Fix is a lightweight optimization mod that targets hidden memory leaks in Minecraft itself and many mods, stabilizing both client and Minecraft server sessions. By cleaning up unused data during play, it greatly slows the usual rise in RAM usage that causes long term stutters or crashes.

The mod focuses on performance, not changing gameplay, so your worlds, plugins and modpacks behave exactly the same, only more stable. Compatible with many Java versions and popular loaders, it works on solo worlds and multiplayer, making it ideal for long running worlds hosted by BoxToPlay or on your own machine.
