How It Works

PlayerSync uses a central MySQL or MariaDB database to store your player data. When you join a server, your data is loaded from the database. When you leave or your data is saved, it is updated in the database. This ensures your progress is always up to date, no matter which server you play on.

Q: Does this work for singleplayer? A: PlayerSync is designed for multi-server networks. It is not needed for singleplayer.
