Savehop: a FREE tiny Windows app that lets your friend group share one co-op save without anyone hosting a server
Built this because every single co-op night with my friends collapsed the same way: whoever started the world was asleep or at work, and the rest of us were stuck staring at the main menu. Renting a dedicated server for a 3-person Valheim group felt ridiculous, and "just email the save around" turned into "who has the latest save" within two sessions.
Savehop is a 6-character room code + a tiny relay that holds the save and a lock. You press Wake to download the save and claim the lock, play, then press Sleep to upload it back and release the lock. Next person Wakes up exactly where you left off. That's the whole product.
- Free, MIT, no account, identified by a local UUID
- Works with any game that saves a file to disk (Subnautica 2, Stardew, Valheim, Satisfactory, Minecraft, Terraria, Schedule I…)
- ~7 MB installer, Tauri + Rust (not Electron)
- Self-hostable in one `docker compose up -d`
- Windows 10/11 for now; macOS/Linux on the roadmap
Maker here, happy to answer anything. The whole server is ~300 lines of Node — easy to audit, easy to fork.
