In their own words
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.
CloudZero
CloudZero is a web and API platform that links AI and cloud spending to business outcomes for finance, engineering, and IT teams. It organizes costs by dimensions such as customer, feature, and product, whether or not tags are present. Explorer supports spend analysis, spike investigation, and per-outcome economics. Streaming telemetry captures AI calls as they occur and supports attribution to customers, products, transactions, and P&L. AI anomaly detection establishes normal spending and alerts on spikes without manual tuning. Budgets and forecasts are included. Integrations cover AWS, GCP, Azure, Kubernetes, Snowflake, Anthropic, OpenAI, Datadog, Databricks, MongoDB, and New Relic. The AnyCost API and common data model ingest billing and usage data without an official connector. CloudZero says data is encrypted at rest and in motion and partitioned by customer. Pricing is on request, with tiered pricing and no monthly overages.
