On the occasion of the French-German Summit on European Digital Sovereignty on 18 November 2025, the European Open Source industry associations and their members have come together to declare that digital independence is possible.
Digital Sovereignty for Europe means that we take back control over digital technology – from its design and development, to daily operation and long-term maintenance – creating resilience against economic pressure, attacks on democratic sovereignty, or even military aggression, and avoiding lock-ins to proprietary ecosystems.
Europe is an important market for international businesses, but more so, Europe has the capacity and talent in research and development, business, and finance to shape digital technology respecting our common values and contributing to welfare and prosperity.
In order to seize the opportunity and unlock the full potential for the European economy, the undersigned European Open Source industry associations and their member companies provide products, services and solutions that implement alternatives for the government stack and put an end to digital dependencies in the public and the private sector.
We offer the full stack of enterprise-grade solutions from network infrastructure, data centres and cloud infrastructure, operating systems, software development tools and build pipelines, to office desktop solutions, cooperation and communication apps, and much more.
We offer the expertise, services, and local competent partners to realise the digital sovereignty goals of France, Germany, and the European Union.
On the occasion of the French-German Summit on European Digital Sovereignty, we are declaring that digital independence is possible, and call on the President of the French Republic, and the Federal Chancellor of the Federal Republic of Germany to make use of the resources we, the industry enabling Open Source, provide to promote and realise digital sovereignty, and as an overall lever for European global competitiveness, economic sovereignty, and innovation.
