What the EU Is Actually Asking Open Source Projects to Prove

The European Commission wants clarity from open source projects. Here’s what they’re asking, why it matters, and what it could mean for developers in plain English. If you’ve ever contributed to an open source project, or rely on one every day, this might affect you, but not in the way you think.

The Request in Plain Terms

The EU’s call for evidence boils down to a few key areas that matter for project health and sustainability.

• Project governance: How contributors, maintainers, and decision-making are structured.
• Funding and sustainability: Where support comes from and how the project stays active.
• Licensing clarity: Ensuring licenses are explicit and accessible.
• Security practices: How the project manages risks and protects users.

What This Means for Developers

Most open source projects won’t need to panic. The EU is looking for clarity and evidence, not trying to catch anyone off guard. Understanding these points now can save surprises later.

Why the EU Is Doing This

The rationale is straightforward: protect users, encourage sustainable projects, and reduce risks in supply chains. By showing what makes projects healthy, the EU hopes to create a more reliable software ecosystem.

Takeaways for Project Maintainers

• Make governance clear with README files and contributor guidelines.
• Track funding sources and sponsorships to show sustainability.
• Document security practices, even if simple.
• Keep licenses explicit and easily accessible.

The European Commission's Call for Evidence on open source projects is exclusively for the EU. It's an internal EU policy initiative to inform their forthcoming European Open Digital Ecosystems strategy (expected Q1 2026).

Closing Thoughts

This isn’t about policing open source. It’s about understanding what makes a healthy project work, and giving developers a roadmap to demonstrate it. For anyone who wants to dig deeper, the EU has published a public Call for Evidence inviting developers and stakeholders to share input on how open source should be approached going forward.
