Cubi dashboard showing the address to share with friends

Three steps. That's it.

From download to playing together.

Create

Pick how you want to play: vanilla, plugins or mods. Cubi downloads the server and the right Java for you.

Start

The server starts by itself and gets a public address. Nothing to set up on your router.

Copy the address and send it to your friends. They paste it in Multiplayer → Add Server.

Play with friends from anywhere

A public address in one click. Link a free playit.gg account for a permanent address, or use the built-in tunnel. No port forwarding.

Dashboard with the address to share with friends

Know your players

Everyone who joined, with a 3D skin wearing their armor, stats, and their inventory and ender chest with real item icons — modded items too. Op, whitelist, kick or ban in one click.

Mods and plugins without the hassle

Search Modrinth and install mods, plugins and whole modpacks from inside the app. The installed list shows readable names, not jar files.

Your worlds, safe

Automatic backups on a schedule. Restore, download or import a world in one click.
