K8s Manifest Deprecation Checker
Paste your Kubernetes YAML manifest. Instantly see which APIs are deprecated or removed in your target version — with replacement paths and migration notes.

FAQ
Does this check my live cluster?
No. This is purely static YAML analysis. Your manifest is parsed entirely in the browser — nothing is sent to any server. It checks the apiVersion fields against a known deprecation database.
Which Kubernetes versions are covered?
The deprecation database covers all major API changes from Kubernetes 1.6 through 1.32+. This includes the big v1beta1 removals in 1.16, 1.22, 1.25, 1.26, 1.29, and 1.32.
Can I paste multiple documents?
Yes. Separate your YAML documents with --- on its own line, just like you would in a standard multi-document YAML file. Each document is parsed and checked independently.
Is my YAML sent anywhere?
No. Everything is parsed and checked in your browser using JavaScript. Your manifest never leaves your device. The only network request is loading the js-yaml library from a CDN.
