Hey Product Hunt! Maker here 👋 I built OpenSave because I kept losing progress moving between my PC and Steam Deck. Steam Cloud only covers Steam games whose devs opted in — my emulator saves, GOG games, and modded playthroughs were on their own. How it actually works, since PH folks usually ask: 🔍 Detection — auto-scan is built on Ludusavi's community-maintained manifest (credit to that project — it's excellent), so it finds save locations for 20,000+ games fully offline. Steam, GOG, Epic, emulators, even repacks. 👀 Watch → snapshot → sync — a filesystem watcher sits on each save folder. The moment a file changes, OpenSave takes a versioned snapshot and pushes it to your paired devices. On the same network that's a direct LAN transfer; across the internet, both devices join a room code through a small relay and the saves travel through an encrypted tunnel. The relay never stores your files, and you can self-host it with one command. ⚔️ Conflicts — if two devices both played offline, OpenSave compares content and asks you which save wins. It never silently overwrites, and every snapshot is kept, so you can roll back any save, ever. The whole thing is one small native Go binary — no Electron, no background services eating RAM, no account, no telemetry. MIT licensed. Happy to answer anything about the P2P architecture, the Steam Deck setup, or why I chose Go + Wails over Electron. And if you try it and something breaks, tell me here or on GitHub — I ship fixes fast.
