Mkn Inventory Sync System
by MKN
Mkn Inventory Sync System lets Fabric servers share player inventories and ender chests without a database, using a folder that every server reads and writes.
What it does
Inventories and End Chests are synchronized between Fabric servers through a shared folder. Each server reads and writes the same location, so a player's items follow them across servers without a database. The mod does not need a proxy server such as Velocity, and no database is required. Setup starts with adding the mod to the mods folder and launching the server once, which generates a JSON config file in the config folder.
The config file sets the location where player data is saved. Path separators should be written with forward slashes, for example C:/Server/inv sync 1.20.1. The design targets setups with several server machines that share one storage location. Fabric API is required, and the mod runs on the server alone, so players join without installing anything. Builds cover 1.20.1 and 26.1.2, with 1.0.0 for 26.1.2 as the latest file, released under the MIT License and not open source.
