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.
Worlds you can walk, not scenes you watch
The reference build is Mini World: zoom out and it reads as a small globe, zoom in and it becomes a surface with regions, oceans you can swim in, and objects you placed yourself. The same builder produces the dioramas and the castle series — the difference between them is only the size of the world and the shape of the base.

FAQ
- Can I build a whole world or just one scene?Both. The same builder makes a single street corner and a whole walkable planet.
- Do I need 3D modelling skills?No. You place, move and describe; the models come from the library or from generation.
- Is there a free 3D world builder online?Yes — this one, and it runs in the browser without an install.
