Space Designer 3D is a browser-based floor plan and interior design software developed by Asynth and used by over 6 million people worldwide since 2010. It lets homeowners, interior designers, architects, real estate professionals, retailers, and educators draw accurate 2D floor plans, furnish spaces from a catalog of thousands of items, and visualize their projects in real-time 3D with one-click photorealistic rendering, all from a web browser with nothing to install. Projects live in the cloud and can be shared, exported as PNG, JPG, PDF, or DXF, embedded on a website, or branded for client-facing work. Based in Aix-en-Provence, France, the team behind Space Designer 3D has been making 3D design accessible to everyone, with no CAD expertise required, for over a decade.
