Kubecost allocates and optimizes spend inside your Kubernetes clusters. Cloud Cost Analyzer finds waste across the rest of your AWS and Azure account. Different scope, and they pair well.
A Kubernetes-focused tool that runs in-cluster on Prometheus to allocate spend by namespace, deployment, and label, and to right-size container requests and limits. Its open-source core is OpenCost. It does not look at cloud resources outside the cluster.
A read-only CLI scan that runs 90 rules across compute, storage, networking, and more, then returns a report of idle and orphaned resources, over-provisioning, and old snapshots, each with the exact fix and estimated savings. It answers what do I do about it?
| Capability | CCA | Kubecost |
|---|---|---|
| Scope | AWS & Azure account | Kubernetes clusters |
| Primary job | Find & fix account waste | Allocate & optimize K8s spend |
| K8s allocation (namespace / pod / label) | ||
| Container right-sizing (requests / limits) | ||
| Cloud resource waste (EBS, EIP, NAT, snapshots, RDS) | 90 rules | |
| Runs without an in-cluster agent | ||
| CLI-first workflow | Partial (API / UI) | |
| Air-gapped / offline mode | Self-hostable | |
| Multi-cloud (AWS + Azure) | Any Kubernetes | |
| Setup time | < 5 min | Deploy agent + Prometheus |
| Price | Free tier + paid | OSS core + paid |
Based on publicly available information about Kubecost. Capabilities may have changed.
You run Kubernetes and need per-namespace, per-pod cost allocation and container right-sizing based on actual usage.
You want to find idle and orphaned cloud resources across the account (outside the cluster) and get a prioritized fix list, run from the CLI or CI/CD.
Kubecost inside the cluster, CCA for everything else in the account. Together they cover both your container spend and the cloud resources around it.
