NickUdon
by FriedOUDON
NickUdon manages nicknames, prefixes and a second nametag line for Minecraft players, with chat and display formatting handled by one shared config.
What it does
Players set a nickname and a prefix that appear in chat, above the head and in the tab list. A second nametag line can carry a subtitle. Formats for display and chat are configurable, and legacy color codes, RGB hex colors in the RRGGBB form, are accepted. Alias uniqueness checks apply normalization rules that the server owner can set, so two players cannot claim the same visible name.
The same project also runs on Paper servers, where it is built as a plugin against the Paper 1.21 API line. Messages are bundled in English, Japanese and a second Japanese locale, and join and quit messages can be overridden to replace the default broadcasts. Formatting, persistence and localization logic are shared between the Fabric and Paper builds, while each platform supplies its own adapter. Fabric is the loader for this listing, and it requires Fabric API and Text Placeholder API. The mod is open source under the GNU General Public License v3.0 or later, and it is published for 1.21.10 – 26.1.2 with 2.0.2 for 1.21.11 as the latest Fabric file.
Key features
Nickname and prefix manager
Each player can hold a nickname and a prefix, and both are shown wherever the formatting config places them.
Second nametag line
A subtitle line can be added below the player name above the head, using the same formatting rules.
Placeholder support
Values can be inserted with Text Placeholder API syntax, so other installed mods that provide placeholders can feed the display.
Join and quit overrides
Default join and quit broadcasts can be replaced with custom messages defined in the configuration.

How it compares
Custom Nickname is client-side only and open source under the MIT License, with Fabric files for 1.21.11 – 26.3, so it needs nothing on the server. DisplayName is open source under the GNU Lesser General Public License v3.0 only and is client and server, with Fabric files for 1.21.1 – 26.2, so both sides must run it. Who Is It is client-side only and open source under the Mozilla Public License 2.0, covering 1.21 – 26.3.
