CAST AI

What CAST AI is

CAST AI is an Application Performance Automation platform for cloud-native operations and Kubernetes automation. It automates workload sizing, node scaling, GPU and Spot optimization, and operational issue remediation. Its rightsizing tools adjust CPU and memory requests and limits, along with replica counts, according to workload behavior. For Spot workloads, CAST AI says its engine can predict interruptions up to 30 minutes ahead and move workloads before a slowdown. Agentic runbooks can address operational and security issues, with approval required before each change is shipped.

Teams can connect clusters in read-only mode in minutes without changing infrastructure. Supported environments include AWS, Google Cloud, Azure, Oracle Cloud, IBM Cloud, OpenShift, Rancher, VMware Tanzu, AliCloud, kOps, PostgreSQL, MySQL, and on-premises Kubernetes. Cloud cost capabilities include cost allocation, spend forecasting, rightsizing guidance, and commitment management. Listed integrations include Grafana, Terraform, Crossplane, Prometheus, Jira, OpenTelemetry, Helm, and Pulumi. CAST AI is available as web and self-hosted software. It is a paid service with custom pricing based on the customer’s environment, and a free trial is available. The company names Leon Kuperman, Laurent Gil, and Yuri Frayman as co-founders.
