Kubernetes Toolkit

Validate, format, calculate resources, diff, explore relationships, and merge or compare Helm values for Kubernetes manifests — seven tools covering correctness, readability, and resource planning. All run entirely in your browser.

How these fit together

Kubernetes YAML Validator catches what kubectl apply would reject — a removed apiVersion, an invalid resource name, a missing container image — before you find out the hard way. Once a bundle is structurally sound, Kubernetes Manifest Explorer computes how its resources actually connect — which Pods a Service's selector matches, which ConfigMap/Secret a workload references, which Ingress rule routes where. Kubernetes Manifest Formatter cleans up indentation and reorders top-level fields into the conventional apiVersion/kind/metadata/spec order. Kubernetes Resource Calculator computes a manifest's total CPU/memory requests and limits and its resulting QoS class instead of you working through the rules by hand. And K8s Diff compares two versions of a manifest field-by-field, with server-managed noise like status and resourceVersion stripped by default. For Helm charts specifically, Helm Values Viewer merges a base values.yaml with as many override files as you actually pass to helm install -f, and shows exactly what Helm computes — including the arrays that get replaced instead of merged, and the YAML quirks that silently change a value's type. And Helm Values Diff takes that same real merge and compares two computed configurations side by side — the fastest way to see exactly what's different between, say, a staging and production deployment.
