## What it is
KubePug is a kubectl plugin and standalone CLI that checks Kubernetes clusters or manifest files for deprecated or deleted APIs before upgrading. It downloads a deprecation database for a target Kubernetes version and reports affected objects along with replacement APIs.

## Use cases
- check for deprecated kubernetes apis before cluster upgrade
- scan kubernetes manifests for removed api versions
- validate helm chart output against a target kubernetes version
- find objects affected by kubernetes api deprecations
- run api deprecation checks in ci pipeline
- find replacement api for deprecated kubernetes resources

## When to choose
- you are planning a kubernetes cluster version upgrade and need to find deprecated or deleted APIs
- you want to validate helm templates or manifests against a future kubernetes version
- you need a kubectl plugin or CI-friendly binary with error exit codes for deprecations

## When to avoid
- you need general kubernetes security or configuration auditing beyond API deprecations
- you want a continuous in-cluster monitoring service rather than a pre-upgrade check
