What users say
Aggregated, with sample sizes. We use whichever review platform has data.
Cast AI and Kubecost both focus on Kubernetes cost management, but they fit different operating models. Cast AI starts with Free (Monitoring) for cost visibility and savings estimates, then moves to Growth at $1,000 per month base + $5/vCPU/month for teams ready to automate cost reduction.
Kubecost starts with Foundations, a free tier for basic Kubernetes cost visibility on a smaller footprint. Its Enterprise Self-Hosted and Enterprise Cloud tiers use custom pricing for organizations that need enterprise-grade Kubernetes cost management at scale.

Our Verdict
Choose Cast AI if you want Kubernetes cost visibility first through Free (Monitoring), then automated optimization through Growth at $1,000 per month base + $5/vCPU/month. Enterprise is custom priced for larger Kubernetes footprints needing dedicated support and volume pricing.
Choose Kubecost if your priority is Kubernetes cost visibility, allocation, chargeback, or showback. Foundations is free for smaller needs, while Enterprise Self-Hosted and Enterprise Cloud are custom priced for larger organizations that need more control or a managed cloud option.
Frequently Asked Questions
01 Is Cast AI cheaper than Kubecost?
Cast AI's free tier covers basic cost reporting, and paid plans scale based on savings generated (up to ~$1,000/mo for most configurations). Kubecost's open-source version is free, while enterprise plans start at $449/mo. For teams primarily needing K8s cost visibility, Kubecost free may be cheaper. For teams focused on active optimization, Cast AI's savings-based pricing means it often pays for itself many times over.
02 Does Cast AI replace Kubecost?
Partially. Cast AI has added cost visibility and reporting features that overlap with Kubecost's core functionality. However, Kubecost's namespace-level, pod-level cost attribution is more granular than Cast AI's reporting. Teams that need detailed chargeback reporting alongside active optimization often run both tools simultaneously.
03 What cloud providers does Cast AI support?
Cast AI supports AWS EKS, Google GKE, and Azure AKS — the three major managed Kubernetes services. It does not support on-premises or custom K8s distributions. Kubecost works with any Kubernetes distribution, including self-managed clusters, making it more flexible for hybrid environments.
