Hoard vs Save Keeper

Hoard syncs game saves across devices and keeps versioned backups on Linux, macOS, Windows, or a self-hosted setup. It detects when you stop playing and syncs saves automatically. If two machines have diverging saves, the newest takes precedence and the other is backed up locally. Snapshots are retained indefinitely, and users can restore an earlier version. Hoard checks files with SHA-256 and re-hashes them during restoration. It detects libraries including Steam, Epic, GOG, Proton, and Wine, and uses the Ludusavi manifest for thousands of titles; the site says save paths for 71 games have been checked by hand. Save export in the game's original format is available even on the free tier. The Free plan includes 2 GB of cloud storage, a maximum save size of 1–1.5 GB, and three devices. Hoard Pro costs €1.99 per month and includes 100 GB of storage, saves up to 10 GB, and unlimited devices. Hoard can also be self-hosted using the same Rust binary, without an account or quotas.
