EmuSync vs QSave

EmuSync syncs game saves between devices by linking save locations to shared storage. It is aimed at people who play emulator or non-Steam games on multiple devices, and at anyone seeking another save backup. Storage can be a local or shared folder, Google Drive, Dropbox, or OneDrive. Users can configure save locations, let the app detect saves, and choose automatic or manual syncing. EmuSync also provides local backup and manual restore. Steam Deck users can check sync status with a Decky plugin without switching to desktop mode. Advanced users and scripts can use its local HTTP API, which requires no authentication and is documented as available only on the device, not over the network. The privacy policy says personal information is not collected, stored, or transmitted; app data stays locally or with the chosen cloud provider. Windows 10 and 11 x64 are confirmed working, and Linux instructions cover Steam Deck. The project says it cannot currently build and test for Mac and has no plans for Android or iOS. Its Windows installer is unsigned and may trigger a SmartScreen warning.

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.
