Name Scanner
by 7Zuck
Name Scanner helps players look for short, rare usernames on a server, reading the current player list from the client side.
What it does
When a player runs the scan command, the mod reads the server's current player list and picks out usernames between one and three characters long. Matches show up in the chat window as the scan runs, accompanied by a plain progress line, so a player can spot which names of one to three characters are online without leaving the game. Because the scan only reads the list the client already receives, it adds little overhead.
The mod is intended for players who collect rare names or want to spot unusual ones before they are taken. It runs on Fabric 1.21.11 and needs Fabric API. Only the client needs it, so servers can run without installing anything, and players may keep using it on any server that allows the scan.
