Open source software has long been viewed as a tactical decision — something engineering teams adopted to move faster or reduce licensing costs. But the data from the 2026 State of Open Source Report by Perforce OpenLogic (produced in collaboration with OSI and the Eclipse Foundation) suggests that the mindset has changed.
This year’s findings point to open source as a strategic concern for IT leadership, shaped by geopolitical pressure, security risk, compliance complexity, and the growing operational burden of maintaining open source software at scale.
Who Took the 2026 State of Open Source Survey?
The 2026 State of Open Source Report is based on more than 700 survey responses from open source software users working across organizations of all sizes, spanning more than a dozen industries and all global regions. The respondents include engineers and architects who are developing, maintaining, and operating production systems built on open source technologies, as well as their leaders (team leads, managers, directors, and C-suite).
The findings reflect real-world operational complexity, not theoretical adoption trends — and capture how open source behaves once it is deeply embedded in enterprise environments, where risk tolerance, regulatory scrutiny, and system longevity all come into play.
Key Finding #1: Vendor Lock-In Concern Is Driving Open Source Adoption
Avoiding vendor lock-in has emerged as one of the leading drivers of open source adoption, cited by 55% of respondents, representing a 68% year-over-year increase. The concern is even more pronounced in Europe, where 63% of organizations in the EU and UK identify vendor lock-in as a primary motivator, compared to 51% in North America.
This signals that open source is increasingly tied to digital sovereignty, long-term control, and exit strategy, rather than short-term cost savings. Open source is being used not just to build software, but to preserve decision-making flexibility in an unpredictable economic and regulatory landscape.
Key Finding #2: Maintenance Is Consuming More Engineering Capacity Than Innovation
The report also highlights a shift in how engineering time is spent once open source is in production. Among the largest enterprises (5,000+ employees), 60% of respondents spend at least half of their time on maintenance, production issues, and bug fixes, rather than on feature development.
For some technology stacks, the imbalance is even more pronounced. The data shows that 31% of enterprise Java teams are devoting only 10-25% to new functionalities, which directly impacts delivery timelines, developer morale, and long-term innovation capacity.
This statistic should raise some alarm bells — but what’s behind it? We know lack of in-house OSS expertise is a common problem that can lead to companies having deployment and/or application issues that they do not have staff capable of remedying. The other possible culprit for Java developers in particular may be the accelerated six-month JDK release cadence that demands more frequent upgrades. This could also explain why teams are stuck on an upgrade treadmill with little time left to build business-critical features.
Key Finding #3: Security and Vulnerability Management Remain Core Weak Points
Despite growing maturity in open source adoption, security updates and patching remain the most persistent challenge, regardless of organization size.
Also notable:
- 20% of organizations report having no specific process for responding to CVEs
- 39% of large enterprises struggle to meet their internal SLAs for vulnerability remediation
- 55% of organizations that failed a compliance audit last year have EOL open source software in their stacks
This gap is especially concerning for those responsible for risk management, compliance, and audit readiness. When open source is foundational infrastructure, vulnerability response becomes a business-critical liability that needs to be addressed through tooling, ownership, and accountability.
In Conclusion
Taken together, the 2026 findings suggest that open source success at scale depends less on what technologies are adopted and more on how they are governed and sustained.
For technology leaders, the data raises several critical questions:
- Do we have clear ownership and processes for maintaining open source in production over time?
- Are our security and vulnerability workflows aligned with the scale of our OSS footprint?
- How does open source fit into our broader strategy around vendor risk, compliance, and digital autonomy?
- Is it necessary to upskill staff or partner with contractors/3rd parties to assist with OSS maintenance and operativity?
The 2026 State of Open Source Report makes one thing abundantly clear: open source is no longer just an engineering preference. It is a strategic asset and a strategic responsibility. Less than 2% of organizations reported a decrease in their OSS consumption in the last year; for the 98% who increased or maintained their usage, the challenge is figuring out how best to support, secure, and sustain it at enterprise scale without sacrificing innovation, resilience, or control.
