In the CNCF Landscape, projects are categorized into Sandbox, Incubated, and Graduated stages. Which stage indicates the most mature projects?

• A. Sandbox
• B. Incubated
• C. Graduated
• D. Active

Answer: (C)

Projects move through maturity levels to show how established they are. The most mature stage is Graduated. This level means the project has strong, stable governance, clear leadership and contribution processes, solid security and license practices, sustained maintenance, and broad adoption across users and ecosystems. Sandbox is for early experiments with limited governance, and incubated represents a more mature project still evolving toward the higher standards of Graduated. Active isn’t a formal CNCF stage. So, Graduated best signals the highest level of maturity.
