How it works

Step What
Create On the Worlds Dashboard, pick a game and a style and give it a name. Review, then Create world. Every rule can be changed afterwards in its Settings.
Play Copy the address from the Dashboard into the game. Share it, and the password if you set one, with anyone you want in.
Manage Your world gets a private Discord thread with Wake, Sleep, Restart and Back up now. Settings, mods, the password and downloads live on the Dashboard.
Share Add up to 10 co-stewards, who can restart it, back it up and change its settings, and players, who can wake it and put it to sleep. Open it to everyone and any member can wake it from #worlds-live.

Core worlds

Always on, open to every member, and outside the world slots.

Valheim · JCBXalways on

The flagship Valheim world lives on Worlds too, and never sleeps. Open to every member, no password, the JCBX rules. Its own page has the details: valheim.jcbx.io.

Enshrouded · JCBXalways on

Up to 16 players on JCBX Style, no password. Its address is on its card in #worlds-live, and its own page has every rule it runs: enshrouded.jcbx.io. It will be wiped when Enshrouded 1.0 releases.

Security

Like every JCBX server, a world is not on the public internet.

Network access Private Tailscale mesh only
Password Optional. None by default: the private network is the gate
Server browser Valheim and Abiotic Factor: not listed. Dragonwilds and Enshrouded: listed as [JCBX] name · jcbx.io; joining still needs the JCBX network
Controls Only you and the people you add, checked on every press

Getting started

Three steps. If you already play on a JCBX server, the first is done.

Step What
1 In Discord, open #get-connected and tap Get connected. The guided setup creates your free Tailscale account and puts you on the network.
2 Open #worlds and press Link my account: one tap there, then one accept in Tailscale.
3 Open the Worlds Dashboard from #worlds and create your world.
