While most FinOps tools only offer recommendations, this free platform automates Kubernetes cost optimization across 190 reviews.
CAST AI works well when you need automated, multi-cloud Kubernetes scaling with simultaneous VPA and HPA support. The friction starts when you require bare-metal on-premise infrastructure support, or when scaling issues trigger incorrect recommendations that impact workload performance. Before buying, compare vs Anthos, which supports bare-metal deployments on-premise.
