RIOT OS: sovereignty score and 8 European alternatives

RIOT is a free, open-source operating system for low-power Internet of Things devices. It is developed on GitHub by a community of companies, academics and hobbyists, and most of its software is licensed under the GNU LGPL version 2.1. Some proprietary drivers are included where no free alternative exists. Developers run RIOT on their own devices, so it is a building block rather than a hosted service.

The project does not name a company or foundation as its legal owner on its website. It is supported by Freie Universität Berlin, INRIA and Hamburg University of Applied Sciences, which founded it in 2013. Decisions are taken by rough consensus among maintainers, and anyone can contribute. For a European organisation, RIOT offers source code that can be inspected and self-hosted, but support depends on the community or on third-party service providers rather than on a single commercial supplier.

Why digital sovereignty matters with RIOT OS

RIOT OS is headquartered in DE 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 RIOT OS scores best on data residency.

RIOT OS 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 RIOT OS together with your other vendors and gives a total score, a heatmap and the main risk drivers.
