Since 2020, the use and development of Open Source Software (OSS) by the Austrian public sector has gradually taken on more strategic importance, with a number of digitalisation strategies and action plans directly referring to open source. The National Strategic Roadmap for the Austrian Digital Decade and the Digital Action Plan on Digital Sovereignty, for instance, position open source as a critical pillar of a sovereign and resilient digital transformation for Austria. The Austrian government supports OSS as a means to achieve digital sovereignty by avoiding vendor lock-in and increasing digital skills, and has been further encouraging its use by the public sector. A number of initiatives at the federal and local levels are aiming to increase awareness and knowledge of OSS, including through software repositories.

Demonstrating this strategic shift towards OSS, the Austrian Federal Chancellery in 2022 set up an open source working group within the Chief Digital Officer Task Force. This working group was created to analyse the state of OSS use by the public sector in Austria and to outline recommendations for encouraging the use of OSS. The results of this working group have been published in a report outlining guidelines on open source use for the public administration.

This view of open source as a driver of digital sovereignty and economic competitiveness is also demonstrated at the local level, with Vienna’s city government engaged in a number of open source initiatives. The city of Vienna, the local authority for both the capital city and its surrounding state, directly refers to open source in its Digital Agenda 2030 and uses its role as the city’s main provider of IT services to encourage the use of OSS by both the public and private sector.
