## What it is
kube-capacity is a Go CLI that provides an overview of CPU and memory resource requests, limits, and utilization across a Kubernetes cluster. It combines the best parts of kubectl top and kubectl describe output into a single, easy-to-read resource report.

## Use cases
- check cpu and memory utilization across a kubernetes cluster
- see resource requests and limits per node
- find which pods are consuming the most resources
- plan cluster capacity before scaling
- compare requested vs actual resource usage in kubernetes
- audit namespace resource allocation

## When to choose
- you want a quick cluster-wide resource overview without running multiple kubectl commands
- you need pod-level or node-level breakdowns of requests, limits, and utilization
- you want a kubectl plugin installable via krew

## When to avoid
- you need full monitoring, alerting, or historical metrics - use Prometheus instead
- you need GPU or custom resource tracking
- you are not working with Kubernetes

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, monitoring, developer-tools
- domain: monitoring
- platform: cli, go, cross-platform
- tags: kubernetes, resource-management, kubectl, capacity-planning, resource-utilization, devops, containers, command-line
