What does CAST AI do?
CAST AI is a platform designed to monitor, analyze, and optimize the costs of running applications on Kubernetes. It connects to your cloud accounts—supporting AWS, Google Cloud, and Azure—and provides a detailed breakdown of where your money is going. The tool visualizes spending across clusters, namespaces, and individual workloads, making it clear which parts of your infrastructure are the most expensive. The goal is to give teams the data they need to control cloud bills without sacrificing performance.
The platform uses AI to analyze your resource usage and configuration. It looks for inefficiencies like over-provisioned nodes, underutilized pods, or idle resources, and then suggests specific actions to reduce costs. These recommendations can include rightsizing instances, implementing auto-scaling, or switching to more cost-effective cloud services. CAST AI also tracks spending trends over time and can alert you to unusual cost spikes, helping you catch problems before they blow the budget.
This tool is built for engineering and platform teams that manage Kubernetes in production. It's useful for companies seeing their cloud costs rise unpredictably and for teams tasked with implementing FinOps practices. By providing clear, actionable insights, CAST AI helps engineers make informed decisions about resource allocation, supports budget planning with forecasts, and ultimately aims to reduce cloud waste while maintaining application reliability.
