Sweet Home 3D: sovereignty score and 8 European alternatives

Sweet Home 3D is a program for drawing the plan of a home, arranging furniture and viewing the result in 3D. It runs on Windows, macOS, Linux, iOS and Android, and can also be used online in a WebGL-enabled browser. The original developer, Emmanuel Puybaret, handed the project over in 2024 to Space Mushrooms, which continues its development.

Space Mushrooms is a software company based in Milan, Italy, so it falls under EU law. The program is distributed under the GNU General Public License and published as an open-source project on SourceForge. Because it can be installed on the organisation's own computers and its source code is public, a European organisation can inspect and manage the software itself, without relying on a hosted service. Space Mushrooms states that its aim is to preserve the program's community and open-source approach.

Why digital sovereignty matters with Sweet Home 3D

Sweet Home 3D is headquartered in IT and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Sweet Home 3D scores best on data residency.

Sweet Home 3D is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Sweet Home 3D together with your other vendors and gives a total score, a heatmap and the main risk drivers.
