Open-source home design and floor plan editor in Rust (a Sweet Home 3D alternative) with a built-in MCP server: your AI agent draws walls, furnishes rooms, checks lighting and ergonomics, and renders
An open-source home design editor in Rust, inspired by Sweet Home 3D, that is AI-native from day one: the editor ships with a built-in Model Context Protocol server, so an AI agent can design alongside you and every change shows up live on screen.
macOS (Apple Silicon and Intel) — open Terminal and paste:
That's it: the app shows up in the Start menu / Launchpad, no administrator password, and the same command updates it. Prefer a plain download?

The builds aren't signed with a paid Apple or Microsoft certificate, so the system asks once:
- Windows: unzip, open newera-gui.exe; if SmartScreen appears, click More info → Run anyway. - macOS: unzip and move 3D New Era AI to Applications. Right-click it → Open → Open. On macOS 15 and later, open it once, then go to System Settings → Privacy & Security → Open Anyway. Or run xattr -dr com.apple.quarantine "/Applications/3D New Era AI.app". - Linux: tar xzf newera-linux-x64.tar.gz && ./newera/newera. Run ./newera/install-desktop.sh to add it to the menu with its icon and to give .newera files their own icon and double click (--uninstall undoes it).
The one-line installers above skip these prompts.
Next: connect your AI — Claude, Codex, Gemini, Cursor, VS Code, DeepSeek and others.
A real 105 m² apartment, traced from an openly licensed floor plan and furnished, lit and photographed by an AI agent through MCP alone — walls from the scan, doors that swing the right way, slatted TV wall, L kitchen and wardrobe from cabinetrun, downlights sized by pho
