OpenSave
What it is
OpenSave is a free, open-source tool for syncing game saves among a user’s devices, including emulator saves and games outside Steam Cloud. It can identify supported games using an offline, community-maintained index of more than 20,000 titles, or monitor a folder or file selected by the user. Devices on the same Wi-Fi can discover one another; connections over the internet use a room code and do not require an account or port forwarding. OpenSave keeps versioned snapshots and offers rollback and branches, while detected conflicts are presented for the user to resolve. Optional backups can be mirrored to Google Drive, Dropbox, OneDrive, WebDAV, or a NAS folder. On a LAN, devices communicate directly; internet sync uses an encrypted connection to a stateless relay, but encryption ends there and the relay could read forwarded data. Users can self-host the relay and operate the daemon and CLI through a local API. OpenSave supports Windows, Linux, Steam Deck, and macOS. On stock Steam Deck, the Linux tarball will not start; the site directs users to the Flatpak.
For and against
For
- Free and open source under the MIT license
- Offline game index covers more than 20,000 titles
- Snapshots support rollback and branches
- Optional backup destinations include cloud storage and NAS
- No account or port forwarding needed for internet pairing
Against
- Internet relay can read forwarded data
- Stock Steam Deck needs the Flatpak, not Linux tarball
- Conflict resolution requires user input
The verdict
OpenSave combines game-save syncing with snapshots, conflict handling, and optional backups. Consider its relay privacy caveat and Steam Deck installation limitation before choosing a setup.
Who it suits
OpenSave suits players who want to keep game saves synchronized across devices, including for emulators or titles outside Steam Cloud. Its self-hosting and command-line options may also suit users managing saves on servers, NAS devices, or scripts.
