Key capabilities include standardizing CI/CD tooling and processes across vendors, languages, and deployment environments, compatibility with Jenkins, Jenkins X, Skaffold, Knative, and other CI/CD tools, cloud native execution, and abstraction of the underlying implementation so teams can choose their own build, test, and deploy workflow. It is aimed at developers and teams building CI/CD pipelines. The page describes Tekton as an incubating project at the Cloud Native Computing Foundation. No pricing model is stated.
