As of Minecraft 1.21.9, the DimWorldBorder mod is obsolete, as the functionality for independently configuring world borders for each dimension will be added to the base game!
DimWorldBorder is a mod for Minecraft 1.21 on NeoForge/Fabric, enabling server administrators to customize world borders independently for each dimension (Overworld, Nether, End, and others).
Server-side only; no client installation required.
