Nickmask
by Palewls
Nickmask hides the sender names of public chat messages, advancement announcements and death messages on a Fabric server.
What it does
Nickmask replaces the visible sender name in normal public chat with a short symbol mask, so the sender of a message is not shown by name. Advancement announcements lose the player name in the same way, and the killer's name is masked in death messages. A dead player's own name stays visible in their death message. The real sender name is still shown to the server and to the chat log.
Nickmask runs only on the server and needs Fabric Loader to start on Minecraft Java 1.21.11. Only the server needs it, so players join without installing anything. Its latest Fabric file, 1.0.1 for 1.21.11, was published on 2026-06-02 on the beta channel. The mod is released under the Apache License 2.0, and it is not open source. Its first file dates from 2026-05-26.

Masked death killers

Use cases
Anonymous public chat
Server owners who want players to talk without showing whose name is attached to each line can use the mask on public chat.
Hidden killer names
Servers can keep the killer's identity out of death messages while leaving the victim's name in view.
Who it’s for: Server owners who run survival, social or roleplay servers and want sender and killer names hidden from public messages. Players on those servers need nothing installed, since only the server runs the mod.
