Server Nick

A lightweight Forge mod that lets players change their in-server display name with a simple /nick command. No permission plugins or external tools required.

Your real account name is never changed, so /msg <realname> keeps working. Use /realname <nick> to find who is behind a nickname.

Features

/nick <name> - change your display name instantly
Chat names update for everyone, including vanilla (mod-free) clients
Name tag (above head) and tab list update for clients that have the mod
& color and formatting codes supported (e.g. &c, &l)
Nicknames are saved and survive server restarts
Operators can set or clear other players' nicknames
Configurable: max length, allow colors, chat override, self-nick permission

Note on scope

In Minecraft multiplayer, the name above a player's head and in the tab list is tied to account authentication, so it is controlled by the server. This mod updates chat for all clients, while the name tag and tab list update only on clients that also have the mod installed. For full effect, install the mod on the server and on each client.

Installation

Install Forge for Minecraft 1.20.1.
Put the jar into the mods folder of both the server and the clients.
Join and run /nick TestName.

Requirements

Minecraft 1.20.1
Minecraft Forge 47.x
