dimension lock (server-side)
by GreenData
Dimension Lock lets server operators decide which dimensions players may enter, and which ones stay closed to them.
What it does
Operators define the dimensions that are locked, and the mod stops players from entering them. When a player tries to go into a locked dimension, the player is told that the dimension is locked, so the restriction is explained in game rather than silently blocking the trip. The mod is server-side only, so players join without installing anything and only the server needs the Fabric file.
Dimension Lock also includes a menu for editing the lock settings. Its GUI icons can be customized through custom model data, so server owners can give the screen a look that fits their world. The mod is open source under the GNU Affero General Public License v3.0 or later, and its source code is publicly available. Files are published for Fabric only, for 1.21.5 and 1.21.7, with 1.0.0 for 1.21.7 as the latest release, first published on 2025-05-07 and last updated on 2025-07-13.
Key features
Locked dimensions
Operators choose which dimensions are closed, and players cannot enter them while the lock is active.

A player who attempts to enter a locked dimension receives a message that the dimension is locked.
Icon customization

Use cases
Server progression
A server can keep a dimension closed until players reach a set point in the world, then open it.
Protected dimensions
Operators can keep a dimension closed to all players while they prepare it for play.
Who it’s for: Server owners and operators who want to restrict dimension travel on a Fabric server. Players on the server do not need to install anything.
How it compares
Dimension Control is server-side only and open source under the MIT License, with files for 1.21.4 – 1.21.11, so it covers a wider version range than Dimension Lock. Locked On is client-side only and open source under the MIT License, for 1.21 – 1.21.5, so it works in a different place and is not a server option.
