CAST AI vs Podledger

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.

Podledger is an open-source Kubernetes cost monitoring and optimization platform. It shows real-time spending at pod, workload, and team levels through dashboards. Its AI engine examines workload patterns, resource use, and cost data, then recommends pod right-sizing, node-pool changes, and scheduling adjustments. The Autonomous tier can apply those changes automatically when configurable guardrails allow it. Podledger runs inside your Kubernetes cluster with read-only, least-privilege access and no sidecars, and installation is available through a Helm chart. Community Edition uses the Apache 2.0 license, is self-hosted, always free, and has no stated usage limits. Community supports one cloud and GitHub support. Enterprise adds managed hosting, infrastructure, security patches, automatic updates, RBAC, SSO, multi-cloud coverage for AWS, GCP, and Azure, and priority support with an SLA. Data retention is listed as 30 days. Plans include Community at free (billed Forever free) and Enterprise at usage-based pricing not listed.
