EmuSync vs SaveKnight

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.

SaveKnight is a Windows desktop app for backing up PC game save files and retaining earlier versions. It scans a computer and uses Ludusavi’s database to locate saves; the download page says that database covers more than 10,000 games. The app targets PC games storing saves locally, runs in the background, and backs up when games exit. Cloud copies are encrypted, can be accessed from any PC and synchronize across a user’s gaming PCs. Version history supports manual rollback to an earlier save. The app is open source under the MIT License and built with Tauri and Rust. Windows 10 or 11, 64-bit, is required, along with at least 4 GB RAM, 100 MB free disk space, internet for cloud sync and a SaveKnight account. The Free plan has 2 game profiles and 500 MB storage. Knight costs $5 a month; Legend costs $15 a month.
