Kubernetes Manifest Validator

Local manifest review

Inspect multi-document manifests, resource relationships, security risks, CRDs, diffs, and kubectl commands.

Paste one or more Kubernetes YAML documents…

Parsing, graphing, CRD checks, diff and export run locally. No kubeconfig or cluster API is accessed.

Ready to inspect a manifest bundle

Paste or open Kubernetes YAML to inventory resources, follow dependencies, review security and compare changes.

How to use it

  1. 01

    Load the bundle

    Paste or open bounded multi-document Kubernetes YAML and inventory every API version, kind, namespace, image and reference.

  2. 02

    Review structure and risk

    Follow resource edges and inspect selectors, missing references, workload structure, container security, RBAC, images, probes and resources.

  3. 03

    Compare and reproduce

    Validate custom resources against included CRDs, compare candidate manifests, export masked evidence, and copy safe kubectl review commands.

Frequently asked questions

Does this replace server-side dry-run?

No. The editor performs bounded local structural and policy checks. Admission webhooks, installed APIs, defaults and cluster policy require kubectl server-side dry-run against the target cluster.

Which Kubernetes versions are supported?

Common resource structures are inspected without claiming a complete versioned schema catalog. Included v1 CRD OpenAPI schemas can validate matching custom resources.

Are Secret values safe to export?

The normalized YAML and reports mask Secret data by default, but names, labels and other fields can still be sensitive. Review every export before sharing.

Does the tool contact my cluster?

No. It never loads kubeconfig or calls a Kubernetes API. The displayed kubectl commands run only if you copy and execute them yourself.
