Sweet Home 3D

The application lets users draw a 2‑D floor plan of a house, place furniture and fixtures on it, and then view the result in a 3‑D perspective. It includes a large library of 3‑D models and textures, enabling the creation of realistic interior visualizations and the generation of photo‑realistic images and video renderings.

It is aimed at anyone who wants to plan or redesign interior spaces, from hobbyists to professionals, and runs on macOS as a stable, free desktop program. The software also offers an online version that works in any WebGL‑compatible browser, providing cross‑platform access.

What distinguishes it is the combination of a simple 2‑D drafting interface with immediate 3‑D preview, together with a built‑in collection of thousands of furniture models and hundreds of textures, allowing users to experiment with décor and layout without needing separate rendering tools.
