“Best default for typical Kubernetes teams: mature, GitOps-native CRDs, broad support for cloud and third-party secret stores, workload-identity authentication, templating, refresh, and push workflows without operating another vault; near-tied with Infisical when a team also needs a human-facing system of record”
