Cast AI
Kubernetes and GPU cost automation FinOps platform for rightsizing, spot management, bin-packing, and autonomous cluster optimization.
Platform, SRE, and FinOps teams running meaningful Kubernetes estates that will allow automated rightsizing and node optimization.
Teams without Kubernetes, or buyers who only want commitment-management savings without touching cluster automation.
Verdict
Cast AI fits Kubernetes-heavy shops that want automated cost optimization rather than another spend dashboard. Public packaging includes free monitoring plus Growth and Enterprise dimensions; AWS Marketplace lists Growth from about $1,000 per month and Enterprise from about $5,000 per month with managed-CPU usage charges. Customers report material cluster savings when they trust the automation; permissions and control concerns are the diligence items.
Score Breakdown

| Growth | From ~$1,000 / mo | Automation on; cluster/CPU caps; plus managed-CPU usage |
| Enterprise | From ~$5,000 / mo | Unlimited clusters/CPU dimension; usage still applies |
| Managed CPU usage | Usage meter | Marketplace lists ~$0.0069 / managed CPU-hour |

Who it’s for
Good fit
- K8s platform teams ready for automation

Poor fit
- Non-Kubernetes estates
- Buyers who will not grant automation permissions
- Teams that only want RI/SP managers
Review Excerpts
Below are excerpts from public reviews. Paid reviews and pay-for-play sites such as Clutch were excluded.
“Cast AI actually changes the cluster instead of only showing charts, and the savings showed up once we let workload and node automation run.”
“We use it for rightsizing, bin-packing, and spot automation across EKS so platform engineers are not hand-tuning every namespace.”
“Cast AI's free visibility let me inspect the cluster before Growth automation touched production nodes. Seeing the cluster first is why I was willing to try Cast AI.”
“You have to be comfortable with autonomous infrastructure changes, and the per-CPU meter means large estates need a careful ROI model.”
