3D World Builder Online — No Install, Playable in the Browser (Free)

Build Your 3D Game in One Sentence

Describe the world and it is built as real Three.js geometry you can walk through, edit and publish — in the browser, free to start.

Online means the same world everywhere

The reason to want an online builder is not convenience, it is parity: the thing you made on a laptop opens at the same quality on a phone, and the person you send it to sees what you saw. Nothing has to be packaged, zipped or explained.

How it goes

01

Open the builder in a tab.

02

Build the world — place, generate, adjust.

03

Publish.

04

Open the same link on a phone to check it yourself.

FAQ

Is there anything to download?No. There is no install for the builder and none for the person playing it.
Does it work offline?Some of the 3D experiences are single self-contained pages that work offline; the builder itself needs a connection to generate.
Can I share what I build?Yes — every world has its own URL, and can be opened full screen or embedded.
