What it is

A local-first 3D editor for modeling buildings, rooms, walls, and furniture layouts, running in the browser on WebGPU and started from a CLI or a single Docker container. It exposes an MCP service so AI agents can read and change scenes, and ships agent skills for scene work and furniture-fit checks. Architects, home builders, and developers experimenting with agent-driven design can keep projects in a local SQLite store or host the editor for a team.
