When Kubecost Might Be the Better Fit

Kubecost is the right choice if your cloud costs are overwhelmingly Kubernetes and you need deep per-pod, per-container, per-namespace cost allocation with engineering-level granularity. The open-source OpenCost project gives you basic K8s cost visibility for free, and Kubecost's commercial offering adds allocation, budgeting, and rightsizing recommendations specifically for K8s workloads. If K8s is 90%+ of your bill and you have a platform engineering team to manage it, Kubecost's depth is unmatched.

Why Teams Switch to CloudExpat

Beyond Kubernetes

Most organizations run far more than just Kubernetes. Databases, storage, networking, serverless, data pipelines — CloudExpat optimizes your entire cloud footprint, not just the K8s portion.

No Agent Deployment

Kubecost requires deploying an in-cluster agent (Prometheus + Kubecost pods) in every cluster. CloudExpat connects via cloud provider APIs — no agents, no cluster changes, no security review for in-cluster software.

Automated Execution

Kubecost shows you cost data and recommendations. CloudExpat acts on them — rightsizing instances, purchasing commitments, cleaning up waste — with your approval.

Commitment Management

Reserved Instances and Savings Plans often represent the single biggest cost reduction opportunity. Kubecost doesn't touch commitments. CloudExpat automates the analysis and purchasing.

Switching from Kubecost

Easy — complementary tools

CloudExpat and Kubecost solve different problems. If you need deep K8s cost allocation (per-pod, per-label), keep Kubecost for that visibility. Add CloudExpat for everything else — commitment optimization, non-K8s resources, and automated execution. Many teams run both. If you want to consolidate, CloudExpat's K8s visibility covers most teams' needs unless you require pod-level granularity.

Frequently Asked Questions

What is OpenCost and how does it relate to Kubecost?
OpenCost is the open-source Kubernetes cost monitoring project that Kubecost created and donated to the CNCF. It provides basic cost allocation for Kubernetes clusters. Kubecost's commercial product builds on OpenCost with additional features like multi-cluster support, budgeting, and enterprise governance.
Can CloudExpat show per-pod Kubernetes costs?
CloudExpat provides Kubernetes cost visibility at the cluster and namespace level. For per-pod and per-container cost allocation, Kubecost's in-cluster agent provides deeper granularity. Most teams find namespace-level visibility sufficient for cost management decisions.
Is Kubecost free?
OpenCost (the open-source base) is free for single-cluster basic monitoring. Kubecost's commercial tiers add multi-cluster support, unified dashboards, enterprise SSO, and advanced allocation — these are priced per-node and can add up quickly for large deployments.
What percentage of cloud cost is typically Kubernetes?
It varies widely. For cloud-native organizations, K8s might be 50-70% of compute costs, but compute itself is often only 40-60% of the total cloud bill. Storage, databases, networking, and data transfer make up the rest — and that's where CloudExpat's full-stack approach captures savings Kubecost can't.
