The European Union unveiled its Open Source Strategy as a cornerstone of digital sovereignty, positioning open technologies against proprietary solutions from outside Europe. The strategy integrates within the EU Digital Sovereignty Package alongside the Cloud and AI Development Act and Chips Act 2.0, creating a coordinated framework for critical digital infrastructure.

Open source adoption addresses Europe's dependency on non-EU technology providers while strengthening control over software and hardware systems. Public administrations gain interoperability and reduced vendor lock-in, while businesses access innovation ecosystems and lower entry barriers. Citizens benefit from transparent, secure digital services aligned with EU values. However, structural challenges persist including limited funding, scaling difficulties, and fragmented visibility of European solutions.

The strategy employs a full lifecycle approach spanning research to long-term maintenance, targeting operating systems, cloud infrastructure, AI, cybersecurity, and semiconductors. Four key objectives focus on tech sovereignty, ecosystem vibrancy, public administration adoption, and international standards outreach. Concrete actions include procurement guidelines, stewardship toolkits, and skills development through programs like Erasmus+ 2027.

Existing initiatives like the Next Generation Internet Initiative and GenAI4EU already contribute to this ecosystem. The strategy aims to ensure European developers capture economic value from their contributions rather than seeing it flow to dominant non-EU providers. Success depends on stronger coordination and sustainable business models.
