EmuSync vs Game Save Manager

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.

Game Save Manager (GSM) is a Windows desktop application for organizing, backing up, and restoring game saves. Its PCGamingWiki-powered database covers more than 14,000 save locations, and it scans game installation folders and known locations such as Registry, AppData, and Documents. GSM keeps rolling backup history, supports permanently pinned backups, and can rotate older saves automatically. Automatic backups can run on a regular interval or when save files change, and persist across app restarts. For custom games, users can add folders, files, or registry keys and use dynamic path placeholders. The app exports save history to a .gsmr archive that can be imported and merged on another PC. The maker says it detects installations from Steam, Epic, Battle.net, and more, as well as account IDs for Steam, Ubisoft, Epic, Xbox, and Rockstar. The free GitHub plan provides a Windows 64-bit installer under GPL-3.0. The maker's privacy policy says the app runs locally and personal files are not uploaded, stored, or analyzed on its servers. It connects to download necessary data files and does not track in-app usage. A separate download option mentions optional support without stating an amount; website purchases grant a personal, non-transferable license.
