Score: 7.3/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 7)

kube-upgrade-check is a kubectl plugin that scans live Kubernetes clusters to identify potential breakages before upgrading to a target version. It goes beyond API deprecation checks by analyzing managed fields, control-plane settings, volume plugins, node runtimes, and add-on compatibility, and it transparently reports what it could not verify. The project fills a practical gap in Kubernetes upgrade preflight validation.

Target audience: DevOps engineers and platform teams responsible for Kubernetes cluster upgrades
