Map Chameleon
by xiaoma_233
Map Chameleon, a Fabric utility, changes the world name a server sends to client-side map mods, so maps on multi-world servers can show the right name.
What it does
Client-side map mods read the world name from the server, and on a server with several worlds that name can be wrong or shared. Map Chameleon lets a server owner set a custom world name that is sent to connected clients, so each map shows the name the owner wants. The mod is server-side only, which means players join without installing anything and clients need nothing extra.
Setting it up means picking the build that matches the server's Minecraft version and adding it to the server alongside Fabric API, which the mod requires. Map Chameleon is released under the GNU General Public License v3.0 only, and the source code, issue tracker and wiki are public. Files cover 23 release versions, 1.20 – 26.2, with v1.2.2 for 26.2 as the latest build, and the first build was published on 2026-06-26.
Key features
Custom world names
The server sends an owner-chosen world name to client-side map mods, replacing the default one.
Per-version builds
Each release targets one Minecraft version, so the jar must match the server's game version.
Editable config
Settings live in a config file that the server owner edits to set the names sent to clients.

Use cases
Multi-world servers
A network with several worlds can give each one a clear name in client-side map mods, so players can tell them apart.
Who it’s for: Server owners who run Fabric servers with several worlds and want map mods on their players' clients to show a chosen world name.
How it compares
Show map Id is a client-side only Fabric mod under the MIT License for 1.20.4 – 26.3, so it only runs on players' clients and shows map IDs, while Map Chameleon runs on the server and changes the world name it sends. Map Atlas is a client-side only Fabric mod for 1.21.1 – 26.2 under the Apache License 2.0, and it is not open source, so it works on a different side and does not change server-sent names.
