OpenSave vs QSave

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.

QSave backs up video game save files to the user’s own Google Drive. It is free and open source, with downloads for Windows and macOS, including separate Apple Silicon and Intel Mac versions. Its game detection database supports more than 19,000 games, and the home page lists Steam, GOG, Epic and Battle.net. QSave searches installed games, and users can search and filter by those stores. Unsupported games can be added by selecting their save folder. Backups can be restored from Google Drive with one click. Cross-platform path remapping is intended to help carry saves between computers, and users can restore cloud-only games or choose a custom restore location. QSave keeps up to five backups per game, skips uploads when save files have not changed, and warns about possible restore or sync conflicts. Individual cloud backup versions can be deleted. The app can run in the system tray and optionally launch at startup. Windows and macOS may show an installation warning because QSave’s code-signing certificates cost money each year; Ko-fi contributions help fund those certificates.
