About Open Source Observatory (OSOR)

Be part of the OSOR community and make your voice heard!

The Open Source Observatory (OSOR) serves as a place where the open source software (OSS) community can come together to publish news, find out about events, find relevant OSS solutions and read about the use of OSS in public administrations across and beyond Europe.


“OSOR aims to become a trustworthy observatory that provides FOSS expertise and information as well as serves as middle-ground to connect European Public Administrations with other relevant stakeholders. To reach this objective, OSOR will support a dynamic community and further promote the use of FOSS.”

The underlying philosophy is to promote collaboration, sharing and digital development by providing the following main services:

OSOR’s community is characterised by three main stakeholder groups: national and local public administrations, private sector, and citizens such as academics and OSS enthusiasts. Each group can contribute to the further adoption of OSS and benefit from the OSOR initiative by reading up-to-date news and in-depth case studies that are posted on a regular basis.
