The European Union Public Licence (EUPL)


Open source licence

When is this solution for you? 

You want to publish your software, data, documents, specifications or source codes under an open source licence that has a clear legal standing in European law.

What can we offer you? 

The European Union Public Licence is a unique and open source licence created by the European Commission that is available in 23 official EU languages and can be used by anyone.

The purpose of EUPL is to encourage public administrations, starting with the EU institutions themselves, to embrace the free and open source model. It is legally consistent with the copyright law of all 28 Member states, and supports other popular open source licences. It is especially well-suited for public administrations and interoperability tools shared on Joinup.

In May 2017, the European Commission published a new version of the EUPL v.1.2. This version provides a wider compatibility with other open source licences compared to the previous version from 2009.
