No Dimension
by SuperFeda
No Dimension lets a server owner switch off individual dimensions so that they can no longer be entered.
What it does
Disabled dimensions are removed from the world load, so the server does not keep data for them in memory. The mod ignores any dimension listed in the configuration during world creation, which reduces memory use on servers that only play in one dimension, such as a story-driven modpack that uses the Twilight Forest alone. The Overworld, minecraft:overworld, cannot be disabled.
The mod is configured through a file in the config folder named no dimension-common.toml. A dimension can be disabled there, and a portal still active toward it will not teleport anywhere. A player cannot enter a dimension that is disabled, even with the execute command, and the dimension's files are deleted from the save folder. Changes take effect after a game restart. The server requires Fabric API on Fabric and Forge Config API Port on Forge, and the code is open source under the MIT License, with builds for 1.19.3 – 1.20.4.
Key features
Disable a dimension
Any listed dimension except the Overworld can be turned off, which blocks entry to it.
Memory savings
Disabled dimensions are skipped at world loading, so their data is not kept in memory.
Dead portals
A portal that still leads to a disabled dimension does not teleport the player anywhere.
Execute command block
The execute command cannot be used to enter a disabled dimension, so the restriction holds in commands too.

Use cases
Single-dimension modpacks
Story-driven packs that use only one specific dimension can turn off the rest and keep the world lean.
Who it’s for: Server owners who run a modpack built around one dimension and want the others unavailable. The mod runs on the server alone, so players join without installing it.
