Play with friends

The easiest way to play together is a shared world — you host it right in your browser and friends join with a short code. No server, no setup, no account.

How it works

When you open a world to friends, your own browser tab becomes the server. Other players connect to you through a public relay using a short join code. Because your tab is the server, keep it open while you play together — when you close it, the world stops.

Host a shared world

1. 1
   Enter a world

   Start TabWorld, go to Singleplayer, and create or open a world.
2. 2
   Open the pause menu

   Press ESC in-game, then click “Invite”.
3. 3
   Start the shared world

   Click “Start Shared World”. The game gives you a short join code (about 5 letters).
4. 4
   Share the code

   Send the join code to your friends. Keep this tab open the whole time.

Join a friend’s world

1. 1
   Go to Multiplayer

   Start TabWorld and open the “Multiplayer” screen.
2. 2
   Join a shared world

   Click “Direct Connect”, then “Join Shared World”.
3. 3
   Enter the code

   Type the join code your friend gave you and click “Join World”. After a few seconds you’re in.

Good to know

• The host’s tab is the server — friends can only join while the host has the shared world open. Close the tab and it stops.
• Everyone needs unrestricted internet. Some school or workplace networks block the connection.
• Best for a few friends at a time — it’s a peer connection, not a big public server.
• Host and friends should share the same relay list (in the game’s “Network Settings”). The built-in relays work out of the box.

If it doesn’t connect

• Friend can’t find the world — make sure you both have the same relays under “Network Settings”, and that the host still has the shared world running.
• Code doesn’t work — double-check the code, and that the host’s tab is still open.
• Still stuck — try a different relay from the list, or have the host restart the shared world for a fresh code.
