GSM vs Hoard

GSM is free, open-source software for versioned game-save backups on Linux and Windows. It uploads backup sets to cloud storage, synchronizes the library between machines, and restores saves when needed. Ludusavi provides automatic game-save detection, while manual backup is available for games that are not detected. Rclone handles cloud uploads, and GSM creates SHA256 integrity files for each backup. Retention can be configured separately for each game. Restore choices include the newest backup, every stored backup, or the newest backup for one selected game. The project is designed for a shared Linux and Windows library without one system corrupting or deleting the other side's data. Linux distributions include graphical and text interfaces plus AppImage support. Windows offers a graphical build and a single-file EXE. GSM uses Rclone's copy command for cloud operations. The repository uses the MIT License, and its releases page lists “GSM - Definitive edition.”

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.
