About this Mod
SharedWorld
Play with your friends without a dedicated Minecraft server. The mod combines e4mc with Google Drive sync to achieve "fake Minecraft servers" that feel like real Minecraft servers.
How it works
Behind the scenes, the world is synced on Google Drive. The first player to join a 'Shared World' becomes the 'host'. The following players are automatically redirected to the host via e4mc. When the host leaves the game, a new host across the online players is picked and all players automatically reconnect to the new host.
Google Drive permissions
The mod only requests permission to have a private folder where it stores data (that is, your shared worlds). This means that the mod never has access to your entire drive.
Data Privacy
The mod stores on a cloudflare backend only the information it requires to function. That is data like your minecraft UUID and world data. Both the mod and backend are fully opensource under a MIT license. Furthermore, it is possible (and easy) to self-host the backend if you want.
Special thanks
Special thanks to vgskye for creating the e4mc mod. Without it I wouldn't have been able to figure out the networking to create this.

SharedWorld server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is SharedWorld compatible with fabric?
SharedWorld officially supports fabric for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with SharedWorld – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SharedWorld consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
