Panda Per-World-Seed

by TreeOfSelf

Panda Per-World-Seed lets a server owner give the Overworld, Nether and End each their own seed, including custom datapack dimensions.

FabricServer-side onlyCC0 1.0 UniversalOpen source1.21.1 – 26.3

What it does

Each dimension on a Fabric server can take a seed of its own rather than sharing one world seed. The setting also applies to custom dimensions added by datapacks, so modded worlds can use separate seeds as well. Server owners who want a world generated from a chosen seed can replace the seeds used in an existing world. The mod is server-side only, so players join without installing anything. It requires Fabric API and is released under CC0 1.0 Universal, placing it in the public domain as open source. Files cover 1.21.1 – 26.3, with 1.2.0+26.3 for 26.3 as the latest, updated 2026-10-04.

Key features

  1. Independent dimension seeds

    The Overworld, Nether and End can each be set to a separate seed instead of a single shared value.

  2. Custom dimension support

    Dimensions added by datapacks can take their own seeds alongside the vanilla three.

  3. Seed replacement

    Seeds can be swapped for an existing world, so the generated terrain can be chosen from a fixed value.
