Open and go, no installs
DeepCosmo runs entirely in the browser. Create an account, click "Get started" and you are in the editor — no installation package, no environment setup. Your first wall is already waiting.
Start with a single wall
Click two points on the canvas and a wall appears. Walls snap, align and connect to each other automatically — you do not need precise coordinates, just sketch out the room’s outline. Once walls are drawn, doors and windows snap onto them, and resizing is as easy as dragging a slider.
Publish, let the world see
After laying out and decorating, click "Publish" in the editor and your work enters the world square. Anyone can browse your world through its dedicated link — viewing the whole scene from above, or walking inside in first person. Whether it goes public or stays private is entirely up to you.
