Open Source as Default Infrastructure
Open source adoption grew 22% year over year in our 2026 data. Open source is now the default choice across infrastructure categories, from databases to CI/CD tooling, with commercial support and managed versions capturing most of the spending. Buyers increasingly evaluate the open source option first and proprietary alternatives second.
Adoption Patterns
Enterprise adoption of open source solutions increased 40% compared to last year. Adoption is driven by total cost of ownership and control: organizations avoid vendor lock-in and licensing growth surprises. Governance has matured alongside adoption, with more teams running formal license and security scanning before production use.
Spending Patterns
Small and medium businesses account for 44% of open source spending, with enterprise organizations contributing more than in most segments. Budgets grew by an average of 20% in 2026, going mostly to managed services, support, and training rather than licenses. Buyers should price the managed tier against the cost of self-hosting and operating.
What Buyers Evaluate
AI-powered features are the top consideration for 59% of buyers evaluating open source platforms, mirroring the broader market. Integration capabilities influence 74% of purchasing decisions: the project's ecosystem of extensions and integrations often decides the choice between otherwise similar tools.
Regional Deployment Patterns
Cloud-based deployment represents 80% of new open source installations. Self-hosting remains common for data-sensitive workloads, but managed offerings dominate new adoption across regions. Deployment choice is increasingly a data-governance decision rather than a technical one.
Recommendations
Assess the project's license, community health, and security track record before adopting, and define the support path for production use. Pilot the tool on a non-critical workload, measuring operational burden against the alternative. Review the choice annually as project momentum and commercial options change.
