Game Save Genie vs OpenSave

Game Save Genie backs up and syncs PC game saves for games without save protection from their launchers. It uses the Ludusavi database to locate saves for more than 19,000 games, and users can track folders and files manually, including emulator saves. Backups run when a game closes and every 10 minutes while it runs. Each backup is an immutable, checksummed snapshot, and users can restore a selected version. The tool supports Google Drive, OneDrive, S3 buckets, and other rclone destinations; unchanged save files are not uploaded again. Users can pull newer saves onto another PC, with save paths remapped across Windows, Linux, and macOS usernames. Before restoring, it verifies and stages downloads, makes a safety snapshot, and avoids restoring while a game is running. The project says it has no accounts, servers of its own, or telemetry. Windows single-machine backups are described as stable; cross-machine sync and Linux/Steam Deck support are beta. It is free and MIT-licensed.

OpenSave syncs game saves among a user's devices, including emulator saves and games outside Steam Cloud. It can identify games using an offline, community-maintained index of more than 20,000 titles, or track a folder or file selected by the user. Devices can find each other over the same Wi-Fi or pair over the internet with a room code, without an account or port forwarding. OpenSave keeps versioned snapshots and supports rollback and branches; when it finds conflicting saves, it asks the user how to resolve them. Optional snapshot backups can go to Google Drive, Dropbox, OneDrive, WebDAV, or a NAS folder. On a LAN, devices communicate directly. Internet syncing uses an encrypted connection to a stateless relay, but the encryption ends there and the relay could read forwarded data. Users can self-host the relay and manage its daemon and CLI through a local REST/WebSocket API. It is free and MIT-licensed, with Windows, Linux, Steam Deck, and macOS options. On a stock Steam Deck, the Linux tarball will not start; the site recommends the Flatpak.
