## What it is
Robusta KRR (Kubernetes Resource Recommender) is a CLI tool that optimizes resource allocation in Kubernetes clusters. It gathers pod usage data from Prometheus-compatible sources (Thanos, Victoria Metrics, Mimir, managed Prometheus offerings) and recommends CPU and memory requests and limits to reduce costs and improve performance.

## Use cases
- rightsize kubernetes pod cpu and memory requests and limits
- reduce kubernetes cloud costs by eliminating over-provisioned resources
- generate resource recommendation reports from prometheus metrics
- find under-provisioned pods causing performance issues
- audit cluster resource allocation for finops
- automatically apply resource recommendations to deployments

## When to choose
- you run workloads on Kubernetes and already have Prometheus or a compatible metrics backend
- you want CLI-based or automated rightsizing recommendations without adopting a full VPA setup
- you need cost optimization reports across namespaces or clusters

## When to avoid
- you have no Prometheus-compatible metrics history for your cluster
- you need real-time autoscaling rather than periodic recommendations
- you want a fully managed commercial finops platform with dashboards
