LockMap

by Cicada535

LockMap stops players from changing map items on a Fabric server, with commands that lock and release each map on its own.

What it does

Once a map is locked, the server blocks the usual ways of copying it or altering it. The Copying Cartography Table and Copying Crafting Table cannot duplicate a locked map, and the Renaming Anvil cannot rename one. Releasing the lock restores normal behavior for that map alone, so other maps keep their protection.

The mod is lightweight and runs on the server only, so players join without installing it. Each map is handled individually through short commands. An optional display adds the map's owner, date and locking details to the item's lore, which shows who locked a given map and when. The author notes that the mod works on a server and that a client installation is required for it to be used.

LockMap is published for Fabric only, with one build for 1.21.10, released 2026-05-02 under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license, so the code is not open source.

Questions

Does LockMap have to be installed on the client?

The author notes state that a client installation is required. The server side is where the locking works, so the server must run the mod as well.

Can a single map be locked without affecting the others?

Yes. Locking and releasing work per map through short commands, so each map keeps its own state.

Which game version does LockMap support?

The mod is published for 1.21.10 only, with the Fabric loader.
