OpenSave vs Playnite Save Manager

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.

Playnite Save Manager is a Windows plugin for backing up, restoring, and organizing PC game saves within Playnite. It detects save locations automatically, including paths under a user profile, game directory, or emulator directory, and supports relative paths. Backups can include optional notes; when restoring, users can choose an earlier backup and keep selected files or folders from being overwritten. An optional setting creates a backup when a game stops, and the per-game backup limit can be set to 0 for unlimited copies. The plugin also imports and exports save-path configurations, ZIP backup packages, and global configurations with backups. Cloud synchronization runs through Rclone and is described as experimental. Users choose a provider through a setup wizard, but the project does not enumerate providers. Cloud sync can have upload or deletion issues; syncing configuration before a game starts may increase startup time, and restoring before uploads finish can cause cloud pulls or conflicts. Optional version tracking records CRC32 checksums. The plugin is free: free.
