Game Sync
Game Sync uploads a singleplayer world to a player's own cloud storage and pulls it back, so saves stay safe across machines.
What it does
Game Sync is a client-side utility that backs up singleplayer worlds to cloud storage. Sync can run on a timer or after each autosave cycle, and transfers use several threads so large worlds finish faster. Failed uploads are retried file by file, which keeps a sync going on an unstable connection. Configuration happens in an in-game screen reached through Mod Menu, so the config file does not need editing for most options. Before the first load, cloud provider credentials must be entered in the config file, and setup steps are described in the GitHub repository.
Data goes directly to the player's own cloud account through OAuth, with no third-party server or subscription in between. Game Sync runs on the client alone, and no server installation is needed. Files are published for Fabric and NeoForge on 26.1.2, released under the MIT License, with source code and an issue tracker public. Fabric API and YetAnotherConfigLib (YACL) are required, and Mod Menu is optional for the in-game screen.
Key features
Cloud world sync
Worlds are pushed to and pulled from the player's own cloud storage, keeping a copy outside the local machine.
Autosave-triggered sync
A sync can run automatically after each autosave cycle, so backups follow play without manual steps.
Parallel file transfers
Files are uploaded in parallel threads, which shortens the time needed to sync large worlds.
In-game configuration screen
Settings are changed in a screen reached through Mod Menu, without opening the config file for most options.

Toggleable Clouds is a client-side Fabric mod for 1.20.4 – 26.2, open source under the GNU Lesser General Public License v3.0 only, and it changes cloud rendering rather than saves. Locolourtor is client-side on Fabric and NeoForge for 1.21.11 – 26.3 under the MIT License, and it works on colors instead of backups. Game Sync is limited to Fabric and NeoForge on 26.1.2 and does not change any rendering.
