Steam Cloud saves for a Godot game

Steam Auto-Cloud watches a folder you name and syncs it when the game starts and quits. If your save files live in one folder, which in Godot they do (user://), you can turn on Steam Cloud entirely in Steamworks.

1. In Steamworks, open Steam Cloud settings, set a byte and file quota, and enable Auto-Cloud.
2. Add a root path per platform pointing at where user:// lives. On Windows that is the roaming app data folder, under Godot\app_userdata\<your project name>, unless you set application/config/use_custom_user_dir, in which case it is your custom name.
3. Restrict it to your save files with a pattern (for example *.save) so logs and caches are not synced.
4. Publish, then test on two machines.

Set the project name or custom user directory before release: changing it later moves the saves.

For control over what syncs and when, GodotSteam exposes Steam's Remote Storage functions, such as writing and reading a named cloud file. Use it when saves are large, when you want to merge conflicts yourself, or when the game writes files outside one folder. It needs the same Steam Cloud quota set in Steamworks.

• Saving while the game is quitting can race Auto-Cloud's upload; save at checkpoints instead.
• Settings files are per machine (resolution, keybinds); keep them out of the cloud pattern.
• Test a conflict: play offline on one machine, then online on another.

Flockbay builds games on the official Godot engine with saves in user://, which suits Auto-Cloud. Ask its AI for cloud saves through GodotSteam and it writes them into your project. Building is free.
