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.

Features

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.

Our Story

SaveSync started with a simple frustration. AG and KB used to play Schedule 1 together. KB was the host. One day, AG was sick at home while KB was stuck at work. AG wanted to play, but couldn’t. The save lived on the host’s machine, and without the host, the game simply couldn’t continue.

As we started working on a solution, we realized we weren’t alone. Players across many different co-op games were asking the same question: “How do we keep playing when the host is offline?” That’s how SaveSync was born.

We’re both game developers, working on SaveSync part-time, building the low-level systems, the UI, the guides, and the community, because we genuinely care about co-op games. Our goal is simple: To make co-op gaming better — no file juggling, no forced subscriptions, no barriers. Just play.

Support Our Journey

We’re two indie developers building SaveSync part-time, but our dream is to do this full-time. Your support helps us keep improving SaveSync, build more community-friendly tools, and eventually create the games we’ve always wanted to make.

On a personal note, we’re huge fans of planes and simulation games, and we’d love to one day channel that passion into building something in that space too. Every coffee gets us a little closer to making that happen.
