Cloud cost analytics (FinOps) · CAST AI Group, Inc.

CAST AI

Kubernetes cost optimization platform that automates rightsizing, bin-packing and spot-instance usage rather than just reporting spend.

Visit CAST AI Alternatives

CAST AI differs from most FinOps tools by acting on Kubernetes cost rather than only reporting it: it continuously rebalances workloads, swaps nodes for cheaper instance types, automates bin-packing to reduce idle capacity, and shifts eligible workloads onto spot instances, aiming to cut compute cost automatically rather than surfacing a recommendation for an engineer to implement manually. It layers cost visibility, security scanning and autoscaling into one platform tied specifically to Kubernetes clusters across AWS, Azure and Google Cloud. It is cloud-only (connects to and manages existing clusters rather than requiring migration) and its pricing is not published — the vendor states it depends on cluster count, GPU usage and which modules are enabled, and requires a custom quote.
