Playtime Logger
by JustS-js
Playtime Logger records how long each player stays on a server by writing login and logout events to a Google Spreadsheet.
What it does
The mod uses the Google Spreadsheets API to log each player's logins and logouts automatically, then calculates session timeframes and total playtime per player. Once it has initialized, tracking starts without further setup, and the results can be read directly in the sheet. Server owners who want to watch the size of their active player base can use the output to follow it over time.
Installation takes a few steps on the server. The author describes creating a new Google Cloud project, enabling the Sheets API, adding the scope ./auth/spreadsheets, and saving the generated OAuth client JSON file. Fabric API is required, and the mod runs on a dedicated server, with the environment set to server-side only. The license is MIT License, and the code is open source with public links to the source and issue tracker.
The mod was first published and last updated on 2025-01-08. Its only file is 1.0 for 1.20.1, so the game version is single-target.
