TagOnline
by XiGua_TUT
TagOnline lets a player check whether specific other players are currently online, directly from the Fabric client.
What it does
Online status is the mod's core function: it detects whether the players a user specifies are on the server at that moment. The status updates in real time, so the information stays current while the user is connected. Administrators can use it to confirm a particular player is present before a management task, and ordinary players can use it to track friends and team members they want to interact with.
The interface is meant to be simple to operate, and no complex configuration is needed to start tracking players. Server administrators and regular players can both use it. Because the source is closed, the code is not open source, and the license is All rights reserved. TagOnline is published for Fabric and runs on 1.21.1 only. Fabric API and Mod Menu are required dependencies, so both must be installed alongside it. The mod is client-side only, so the server does not need it and players need nothing beyond their own client install.
Key features
Online player detection
Checks whether the players named by the user are on the server, without requiring any server-side installation.
Real-time status updates
Online status refreshes in real time, so the displayed information reflects the current state of the server.
Simple tracking interface
A user-friendly screen lets administrators and regular players select the players they want to watch.
Support for in-server coordination
Knowing who is online helps players arrange interaction and helps administrators verify presence before management work.

How it compares
ClockStopper is an open source, MIT-licensed mod for Fabric that runs on Server-side only and covers 1.21.1 – 1.21.11, so it installs on the server rather than the client. Player Teleport is also open source under the MIT License and covers 1.21 – 1.21.11, but it is server required with client optional, and its purpose is teleporting players. TeamLink, by contrast, is client-side only, MIT-licensed and not open source, and covers 1.20.1 – 1.21.11. TagOnline differs from these by being client-side only, limited to 1.21.1 and released under All rights reserved.
