API Version Deprecation Checker

The API Version Deprecation Checker reads the apiVersion of each manifest you paste and compares it to a target Kubernetes version. It flags apiVersions that were deprecated or removed so you can fix them before an upgrade breaks your workloads.

Pick the Kubernetes version you plan to run, paste one or more manifests, and the tool reports each problem with a recommended replacement.

Nothing is uploaded. The analysis runs entirely in your browser.

• Target aware - choose the Kubernetes version you run.
• Removed vs deprecated - clear severity.
• Common removals - apps, extensions, networking, batch, policy, autoscaling and more.
• Multi-doc - check several manifests at once.
• Copy / Download / Print - export the report.

1. Pick the target Kubernetes version.
2. Paste your manifest(s).
3. Click Check.
4. Fix any REMOVED apiVersions before upgrading.

Example 1 - Ingress. networking.k8s.io/v1beta1 is removed in 1.22; use v1.

Example 2 - Deployment. apps/v1beta1 is removed in 1.16; use apps/v1.

Example 3 - CronJob. batch/v1beta1 is removed in 1.25; use batch/v1.

• Upgrade safety - catch removals before they break.
• Clear guidance - suggested replacement per version.
• Private - runs fully in the browser.
• Exportable - copy, download or print.
