SharedWorld
Play with your friends without a dedicated Minecraft server. SharedWorld combines e4mc with Google Drive sync so the world can keep going even when the host changes.
How it works
Behind the scenes, the world is synced through Google Drive. The
first player to join a Shared World becomes the host. Other players
are automatically redirected to that host through e4mc.
When the host leaves, a new host is picked from the remaining
online players and everyone reconnects automatically.
Google Drive permissions? Is this safe?
The mod only requests permission to use a private app-data folder where it stores SharedWorld data. It does not get access to your entire Google Drive.
