In their own words
Atmosly Kubernetes Cost Optimization
Atmosly Kubernetes Cost Optimization helps teams allocate and manage cloud spending across Amazon EKS, Google GKE and Azure AKS. Its normalized dashboard breaks costs down by account, cluster, namespace and service, with showback views for teams. The product detects idle workloads and orphaned volumes, provides daily budget alerts and monthly forecasts, and ranks reserved-instance and savings-plan opportunities by monthly savings. Right-sizing suggestions use workload p95 usage over time, estimate dollar impact and can be submitted as reviewable pull requests. A connected cluster can be assessed with read-only access; changes require explicit approval. Cost telemetry depends on an existing in-cluster Prometheus instance, and the page says kube-prometheus-stack works out of the box. The Personal plan is free forever for one engineer and one cluster, with cost recommendations in view-only mode and seven-day history. Team signups receive 30 days of Growth features without a credit card for self-serve signup. Paid plans start at $399/mo. The product supports Linux, web and self-hosted use; the self-hosted control plane is available on the Platform tier.
CAST AI
CAST AI is an Application Performance Automation platform for cloud-native operations and Kubernetes automation. It automates workload rightsizing, node scaling, GPU and Spot optimization, and issue remediation. Rightsizing adjusts CPU and memory requests, limits, and replicas in response to workload behavior. The platform says its engine can predict Spot interruptions up to 30 minutes ahead and migrate workloads before a slowdown. Agentic runbooks can address operational and security issues, with approval required for each change before it ships.
Teams can connect clusters in read-only mode without infrastructure changes. Listed environments include AWS, Google Cloud, Azure, Oracle Cloud, IBM Cloud, OpenShift, Rancher, VMware Tanzu, AliCloud, kOps, PostgreSQL, MySQL, and on-prem Kubernetes. Cost tools include allocation, spend forecasting, rightsizing guidance, and commitment management. CAST AI integrates with tools including Grafana, Terraform, Prometheus, Jira, and Pulumi. It is available on the web and as self-hosted software. Pricing is custom and available on request; a free trial is available.
