DimLock
by TLiG
DimLock lets server owners lock dimension portals so that teleportation through them is denied until a defined requirement is met.
What it does
A portal can be switched between a locked and an open state. While it is locked, a player who tries to step through is refused unless the requirement set in the config is satisfied. Locking blocks only the teleport itself, so the portal frame, the ignition and the structure mechanics stay as vanilla leaves them.
The configuration is meant to be simple to edit, and the mod is built around vanilla portal behavior rather than replacing it. The author reports tests with several dimension mods, and notes that compatibility depends on how each other mod implements portal teleportation logic.
DimLock is a Fabric mod for 1.20.1 – 1.20.6, and only the server needs it, so players join without installing anything. The code is released under CC0 1.0 Universal and is open source, with public source code and an issue tracker. The latest file is beta-1.0 for 1.20.6, published on 2026-06-24 on the beta channel.
Key features
Locked and open portals
Each portal works as a binary switch, moved between locked and open by the server.
Requirement gate
A locked portal grants passage only when the player meets the requirement defined in the configuration.
Vanilla portal behavior
Portal creation and structure mechanics remain unchanged, so only the act of teleporting is affected.
Configurable rules
The locking system is set up through a configuration file, with no extra blocks or items needed.

Use cases
Who it’s for: Server owners running Fabric 1.20.1 – 1.20.6 who want to control which players can pass through dimension portals. Single-player players who only need the mod on their own client have no use for it, since it runs on the server side.
