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.
