Chunky for Minecraft Fabric is a mod that lets players pregenerate chunks in Minecraft. Compatible with the Fabric mod loader, this tool optimizes server performance by generating chunks in advance, reducing lag and improving gameplay smoothness. Players can explore vast worlds without experiencing the performance drawbacks of generating chunks on the fly.

Note: The Fabric modloader must be installed. Learn how to here.
