EmuSync review
A free, open-source sync tool with backups, history, and automation options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
EmuSync is a free, open-source desktop tool for synchronizing game-save files across Windows and Linux devices, including Steam Deck through a Decky plugin. It is aimed at gamers who move between multiple devices, use non-Steam games, or need a consistent save location across systems. The tool maps configured save locations on each connected device to a shared synchronization point. Storage options include Google Drive, Dropbox, OneDrive, and local or shared folders. Automatic and manual synchronization are both available, with automatic detection supported through periodic and manual scans.
The product’s strongest fit is cross-device save management with practical safeguards. When new files are downloaded, EmuSync can create automatic local backups, while local sync history logs provide a record of synchronization activity. Available local backups can be restored manually. Device-specific save locations are configurable, which helps accommodate different file paths across connected Windows and Linux systems. The published feature set also includes both cloud synchronization and shared-folder synchronization, giving users a choice between supported storage providers and local infrastructure.
EmuSync also stands out for automation access. Its local HTTP API is designed for automation and third-party tools, and the Steam Deck Decky plugin extends the product to that device environment. However, the scope is narrower than a universal game-save manager: emulated game-save detection is unsupported, and the documented platform coverage centers on Windows and Linux. Users who want automatic detection for emulated saves or broader platform coverage should consider an alternative. EmuSync is a strong choice for users who want an open-source, no-cost way to synchronize saves across Windows, Linux, and Steam Deck, especially when local backups and automation hooks matter.
