Sandbox

The CNCF Sandbox is the entry point for early stage projects.

Maturity Levels

CNCF projects have a maturity level of sandbox, incubating, or graduated which corresponds to the Innovators, Early Adopters, and Early Majority tiers of the Crossing the Chasm diagram. The maturity level is a signal by CNCF as to what sorts of enterprises should be adopting different projects. Projects increase their maturity by demonstrating their sustainability to CNCF’s Technical Oversight Committee: that they have adoption, a healthy rate of changes, committers from multiple organizations, have adopted the CNCF Code of Conduct, and have achieved and maintained the Core Infrastructure Initiative Best Practices Badge. Full details are in the Graduation Criteria v1.1.

CNCF projects can be at sandbox, incubating or graduated stage. View the CNCF graduation criteria and the current status of each project.
