HidePlayer

Hiding a player removes that player from the views of other players on the server. The hidden state applies to in-game visibility of the player model, chat, the tab list and the social screen, so a staff member or service account can stay out of sight without leaving the server. System messages for joins, leaves, deaths and achievements can be hidden for the same players, and so can scoreboard entries.

The mod also covers server status query responses, so a hidden player does not appear in the list a server returns to a status request. It is aimed at server owners who manage staff activity, run mini-games or host server events and need some accounts kept out of the public view. Permissions are refreshed automatically when a player reconnects, which prevents the visibility state from falling out of step after a rejoin.

HidePlayer is a Fabric mod that runs on the server only, so players join without installing anything. It is released under the GNU Affero General Public License v3.0 or later and is open source, with its source code and issue tracker public. Files are published for Fabric across 15 release versions, 1.20.1 – 26.3, and snapshot builds are also published.
