Stay free if you only need unlimited cluster monitoring and detailed savings recommendations. Upgrade if you need advanced self-healing automation and dedicated customer success. Most solo builders can start free.
Why it matters: Usage-based pricing means fees scale with optimization success, potentially reducing net savings on very large deployments
Available from: Optimization (Performance-Based)
Why it matters: Kubernetes-exclusive focus limits value for organizations using mixed container orchestration platforms
Available from: Optimization (Performance-Based)
Why it matters: Requires significant cluster-level permissions that may conflict with strict security policies in regulated industries
Available from: Optimization (Performance-Based)
Why it matters: ROI diminishes for already well-optimized clusters using spot instances and proper resource management

Cast AI offers free unlimited cluster monitoring and recommendations. Paid optimization plans charge a percentage of your realized savings (typically 15-25%). Since exact percentages aren't published, you'll need a sales conversation for custom quotes. The key advantage: you only pay when Cast AI actually saves you money.
Kubecost and similar tools provide visibility and recommendations—they show you what's wrong. Cast AI automatically fixes it. The difference is dashboards versus automation. If you want to see optimization opportunities, use Kubecost. If you want those optimizations implemented automatically, choose Cast AI.
Cast AI starts in read-only monitoring mode so you can evaluate recommendations risk-free. When enabled, all optimizations go through configurable approval workflows and SLO-based guardrails. Companies like Akamai and Yotpo run Cast AI automation on large production environments with zero reported downtime incidents.
Cast AI supports AWS EKS, Microsoft Azure AKS, Google Cloud GKE, and self-managed Kubernetes clusters. The platform provides unified optimization policies and cost visibility across all providers from a single control plane.
Most customers see detailed optimization recommendations within hours of connecting a cluster. Actual savings of 40-70% typically materialize within the first month after enabling automated optimizations. The read-only evaluation period lets you verify projected savings before committing to automation.
Cast AI delivers positive ROI when Kubernetes spending exceeds $5K/month. Below that threshold, the percentage fees may not justify automation. For teams spending $10K+/month, Cast AI's 35-55% net savings (after fees) significantly outperform manual optimization while freeing engineering time for product development.
