World Switcher
by Gerry3010
World Switcher lets a NeoForge server run several worlds at once, and players move between them with a single command.
What it does
Players jump between worlds with the ws command, while the wsc command manages world saves and per-player, per-world state. Each world can keep its own inventory, ender chest, experience and game mode, and a world can be marked as restricted so only players with a set permission level reach it. Worlds can also be grouped so that a set of them shares one inventory, and a player's state can be copied, moved or swapped between worlds, including while that player is offline.
The mod is a Multiverse-style world manager that runs entirely on the server. Vanilla 1.21.1 clients join without installing anything, because World Switcher registers its items and blocks through network payloads that vanilla clients accept. Custom worlds reuse the standard minecraft:overworld dimension type, so vanilla clients accept them. Its player state is dependency-free and configurable per key, so server owners choose which parts of a player's data are kept separate in each world. Files are published for NeoForge 1.21 and 1.21.1, with 1.5.2 for 1.21.1 as the latest release.

Run multiple worlds on one server and let players switch between them with a single command — Multiverse-style, but for NeoForge. 100% server-side: no client installation needed. Vanilla 1.21.1 clients can join without the mod, because World Switcher registers no items, blocks or network payloads — custom worlds use…
