Why SaveSync?

We built SaveSync after seeing how often players asked, "How can we keep playing our co-op world if the host isn't available?" The usual answers, setting up a paid dedicated server or manually transferring files, are either expensive or frustrating. SaveSync solves this with a simple, automated and affordable solution.

Key Features

Everything you need to keep your co-op worlds alive

Cloud Save
The saves you choose are stored on Steam Workshop, encrypted, unlisted, and private by default.
Cross-User Syncing
Share your saves with your friends so anyone can keep hosting. Save files are scanned with Windows Defender before uploading and downloading, for an extra layer of safety.
Host Transfer Made Easy
The save's host changes automatically when activated.
Save Activation Control
Activate or deactivate specific saves to get around in-game save limits–great for games that restrict the number of save slots.
Complements Steam Cloud
Works alongside Steam Cloud without conflict. Save activation/deactivation and host changes reflect properly, even on unsupported platforms.
LAN Sync
Seamlessly play Minecraft and Vintage Story with your Lan friends
