Open source is no longer a niche topic—in 2025, it is clearer than ever how indispensable open software has become for our digital world. Without open source solutions, large parts of data traffic, many platforms, and even smartphones would come to a standstill. At the same time, the open source community is a key driver of innovation, whether in cloud technologies, artificial intelligence, or security solutions.
With the fourth edition of the “Open Source Monitor,” Bitkom provides current figures and assessments on the use of open source software in Germany. Over 1,100 companies were surveyed in a representative sample, supplemented by assessments from around 100 public sector organizations. The result: open source has become an integral part of business and administration.
Widespread use—primarily due to concrete advantages
- Around 75% of companies consciously rely on open source.
- In the public sector, around two-thirds of authorities use such solutions.
The reasons are obvious: open source enables lower costs, customizable software, and the ability to check security aspects yourself. In addition, organizations benefit from an active developer community that constantly provides new features and improvements.
More than just technology: digital sovereignty
Open source goes far beyond pure cost advantages. Because the source code is openly accessible and allows for customization, it strengthens digital sovereignty: companies and administrations retain control over the software they use—or can regain it.
Unsurprisingly, 6 out of 10 companies would like to see the government invest more in open-source software in light of the geopolitical situation.
Challenges remain
Despite the positive development, there are still obstacles to the use of open source:
- Shortage of IT specialists
- Unclear warranty issues
- Legal uncertainties regarding licenses
In addition, many organizations lack a clear strategy: 60% of companies have not yet developed an open source strategy.
Conclusion: Strategic action required
The Open Source Monitor 2025 makes it clear: open source software is a key building block for innovation, security, and digital independence. However, in order for companies, public administration, and the community to fully exploit its potential, more strategy, responsibilities, and clear goals are needed.
Open source is not a sure-fire success—but with targeted investments and smart planning, Germany can strengthen its digital sovereignty and consistently leverage the advantages of open software.
