Native Nicknames
This mod adds native nicknames to Minecraft, on the lowest level possible. Intercepts game profiles just after session authentication.
Nicknamed users will appear identically to the game as if you change your actual Minecraft username.
Intended for friend-only servers with a whitelist, there are no permission checks.
Please note that this mod only works with online-mode=true set in the server.properties.
Duplicates are prevented, but there's no protection against setting a nickname and then having the real user with that nickname join the server - this is unsupported, I do not know what would break if you tried.
It targets Fabric, NeoForge, Forge and Quilt, and supports all major versions since 1.14.4 (powered by Stonecutter & Architectury), as well as 1.12.2 and 1.7.10 (manual ports).
If this mod is missing a version you want to use it on, please open an issue and I will add it when I have time.
Usage
As a player, run /nick set <nickname> to set a nickname, and /nick clear to clear your nickname, then reconnect to the server.
