4D: sovereignty score and 8 European alternatives

4D is a full-stack development environment for building web, mobile and desktop applications. Developers work from one data model and one set of business rules, and they deploy native applications on macOS, Windows, mobile devices and the web. The development environment is installed on the developer's own computer, and the applications it produces run on infrastructure chosen by the customer.

4D SAS is a French simplified joint-stock company (SAS) with its head office in Le Pecq, France. Its legal notice names no parent company or group, so no foreign owner is stated. Because the applications run on the customer's own systems, data protection depends mainly on how the customer hosts them. The vendor's pages do not state a GDPR commitment, so buyers should review the data policy and licence terms before relying on the product for personal data.

Why digital sovereignty matters with 4D

4D is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

4D runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

4D is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs 4D together with your other vendors and gives a total score, a heatmap and the main risk drivers.
