Worlds: Multiverse for Fabric
by Wroud
With Worlds, one Fabric server can run many separate worlds, each with its own time, weather and game rules, and players move between them with commands.
What it does
Each world is loaded once a player enters it and is unloaded shortly after the last player leaves, so a server can keep hundreds of worlds on file without paying for idle ones. Commands create, list, delete and teleport between worlds, and execute can run a command in another world. A world id without a namespace is placed under minecraft, so a world named mining is created as minecraft:mining.
Nothing new has to be learned, since the extra commands for weather, time and rules work across the Overworld, Nether and End the same way. Worlds is built as a base for other mods that add dimensions, and it was recreated from World Manager and Multiworld with one command each. Running worlds commands needs operator level 3, and changing a gamerule needs level 2 as in vanilla.
Fabric API is required, and the mod is published for Fabric and Quilt across 9 release versions, 1.21.8 – 26.3. Files for 26.3 are 1.10.0+26.3, released on 2026-10-07, and the project is released under the MIT License as open source. Snapshot builds are published too. Either side can run it, and neither needs it.
Key features
Unlimited worlds
A single Fabric server can run many worlds, without the per-world setup that Paper-based tools require.
Commands for world management
In-game commands create, list, delete and teleport between worlds, and execute runs a command in another world.
Per-world vanilla behavior
Time, weather, game rules and the End dragon fight apply per world, as in vanilla.
Lazy loading
Worlds load on entry and unload shortly after the last player leaves, so idle worlds use no resources.

Worlds lets a Fabric server run as many worlds as it wants, the way Multiverse does on Paper. Create, list, delete and teleport between worlds with in-game commands, and give each one its own time, weather and game rules.
