An open-source home design, floor plan and interior design editor written in Rust, built so that your AI can design with you. It ships with a Model Context Protocol server: Claude, ChatGPT, Codex, Gemini, Cursor or any other MCP client draws the walls, furnishes the rooms, builds the joinery, checks lighting and ergonomics against real standards and renders the photos, while every change shows up live on screen and is one Ctrl+Z away.
A Sweet Home 3D alternative for Windows, macOS, Linux and the browser, in English, Portuguese, Spanish and French.
