Getting Started

Open the browser, pick a world, and start playing. Here is what to expect on your first launch.

What TabWorld is

TabWorld is a browser-first launcher and play hub for block worlds. It loads a game runtime (1.8.8) directly in your browser tab, then gives you a clean way to manage servers, profiles, and docs around it.

TabWorld is the launcher; the game runs entirely on your device.

What you need

• A modern desktop or mobile browser.
• WebGL and WebAssembly support (the Play page checks this for you).
• A keyboard and mouse for the best desktop experience.

Recommended browsers

Latest Chrome, Edge, or Safari work best. Firefox works too. On mobile, use the latest browser and play in landscape.

Your first launch

   Saved on this device for convenience.
3. 3
   Launch

   The runtime boots in the same tab. The first load may take a little longer while assets cache.
4. 4
   Press a key when prompted

   Browsers require a tap or key press to enable game audio.

Nicknames and config

Your in-game name, controls, and graphics are managed inside the game (Options and Edit Profile). TabWorld stores its own preferences — like your server list — in your browser.
