Embervault
Keep the whole party on one save.
Host a co-op world and Embervault keeps the save file current across the group automatically — encrypted with your keys, on infrastructure you can run yourself.
End-to-end encrypted
Saves are sealed with keys only your group holds. The server stores ciphertext it can't read.
Self-hostable
Run the entire stack yourself, account-free. No lock-in, no middleman.
Automatic co-op sync
The host's save propagates to everyone the moment it changes — no manual uploads.
How it works
1Point it at your save
Name the world and show Embervault where the game keeps it. It watches that folder and nothing else.
2Choose your saves
Pick exactly the files that belong to this world. Embervault touches only those — your other saves stay untouched.
3Invite friends
Send a one-time link. They join in a click — and self-hosters need no account at all.
4Someone hosts
Whoever’s playing hosts; everyone else rides along. Embervault tracks who’s canonical automatically.
5One save, everywhere
Every session lands on the same timeline, whoever played it — end-to-end encrypted, and any point restorable from any machine.
