What OpenSave is

OpenSave syncs game saves between a user’s devices, including emulator saves and games outside Steam Cloud. It can detect games using an offline, community-maintained index of more than 20,000 games, or track a selected folder or file. Devices can find each other on the same Wi-Fi or pair across the internet with a room code, without an account or port forwarding. OpenSave keeps versioned snapshots, supports rollback and branches, and asks users how to resolve detected conflicts. Optional snapshot backups can be mirrored to Google Drive, Dropbox, OneDrive, WebDAV, or a NAS folder. On a local network, devices communicate directly and saves remain on users’ devices unless their own cloud storage is enabled. 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 its headless daemon and CLI through a local REST/WebSocket API. OpenSave is free, open source, and MIT-licensed, with Windows, Linux, Steam Deck, and macOS options. On stock Steam Deck, the Linux tarball will not start; the site directs users to the Flatpak.

Who it suits

OpenSave may suit players who want to sync saves across devices, including emulator games, or manage saves on servers and NAS devices through its CLI. Users who sync over the internet should consider the relay’s access to forwarded data.

Getting started

Open the OpenSave website at https://savesync.qzz.io/.
Choose a listed build for Windows, Linux, macOS, or Steam Deck.
On a stock Steam Deck, use the Flatpak rather than the Linux tarball.
Let OpenSave detect games or select a folder or file to track.
Connect devices over the same Wi-Fi or pair them over the internet with a room code.
Optionally configure snapshot backups to a supported cloud service or NAS folder.

Verdict

OpenSave offers save syncing, version history, and optional backup destinations without a subscription. Its direct local-network model differs from internet syncing, where encryption ends at the relay.
