loginlogger
by shadowbq
loginlogger records every player who joins and leaves a Fabric server, writing each event with a timestamp to a log file.
What it does
Players who connect to a Fabric server are written to logs/login usernames.log with a timestamp. The file keeps both joins and disconnects, so a server owner can check who was online at a given time without relying on the chat or console output.
The mod also flags a player on their first visit. When someone joins for the first time, the mod detects it and records that in the same log, which separates new arrivals from returning players. Only the server needs the mod, so players join without installing anything.
The project is open source under the MIT License and is published for Fabric on 1.21.7 and 1.21.8, with the 1.0.0 file for 1.21.8 as the latest release. Source code and an issue tracker are public.

First-time player detection
