Worlds: Multiverse for Fabric
- By
Run unlimited worlds on one Fabric server, like Multiverse on Paper, World Manager or Multiworld: create, list and teleport with commands. Every world keeps its own time, weather and game rules, and the End dragon, portals and maps work in all of them.
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. Every world plays like real vanilla Minecraft, down to the End dragon, which also makes Worlds a base other mods build their dimensions on. Worlds from World Manager or Multiworld can be recreated with one command each.
World types
/worlds create <id> makes an Overworld. Add from-preset for flat, amplified or any data pack preset, or from-dimension for a Nether, an End or any dimension type. /worlds tp takes you there.
- The End dragon fight, portals, maps and ender pearls work in every world you create, not only in the original three.
- Own weather and time. Vanilla
/weatherand/timerun inside a world change only that world. - Own game rules. Keep inventory, PvP, mob spawning, daylight and more, set with vanilla
/gameruleinside the world. Rules you leave alone follow the server, and/gamerule <rule> inherithands one back. With Worlds installed on the client, the Game Rules screen shows which rules the world changed. - Nothing new to learn. No extra commands for weather, time or rules, and the Overworld, Nether and End behave exactly as in vanilla.
- Load on demand. A world loads when a player enters it and unloads a minute after the last player leaves, so you can keep hundreds of worlds without paying for idle ones.
- Updated within a week of each Minecraft release. Worlds follows the newest Minecraft version; older versions stay on the Versions tab.
- A base for other mods. Mods register their own world types through the Worlds API and let Worlds handle creating, loading, saving and teleporting. Stargate is built on it; API.md has the guide and the Gradle setup.

/worlds create mining
/worlds tp mining
/worlds delete mining
/worlds create mining
A creative build world with no mobs and endless daylight
/worlds create build from-preset minecraft:flat

Moving from World Manager or Multiworld: replace it with Worlds, then run /worlds create <id> from-dimension <type> <seed> with the id, type and seed each world had. Classic Overworld, Nether and End worlds are supported.
