Cast AI's per-cluster model works until you scale. The moment you add clusters — dev, staging, prod, regional, team-specific — the bill compounds. InfraGhost charges flat. Add ten clusters or a hundred. The price doesn't move.

Cast AI's per-cluster model creates a perverse incentive: every new cluster you spin up increases your bill. Dev cluster, staging cluster, regional failover cluster, team-specific environment — before long you're running 8–12 clusters and your "optimize costs" tooling costs more than the infrastructure problem it was solving. InfraGhost doesn't bill per cluster. It never will.
$0 Per-cluster fees on InfraGhost. Always.Cast AI is optimized for Kubernetes workloads. If your infrastructure runs EC2 instances, RDS databases, S3 buckets, security groups, and IAM policies — the non-K8s components don't get the same coverage. Most teams aren't K8s-only. They run a mix of managed services, EC2, databases, and containers. InfraGhost monitors and remediates drift across the full infrastructure stack, not just your clusters.
InfraGhost is priced flat and designed to cover your entire cloud footprint — not just the Kubernetes layer. AWS, GCP, multi-region, multi-account: the price is $49/mo on Solo, $149/mo on Team, $399/mo on Scale. That price doesn't move when you add a cluster, provision a new account, or expand to a second region. You scale; the bill doesn't.
InfraGhost is $49/mo regardless of how many clusters, accounts, or regions you connect. 14-day free trial. Cancel anytime. No per-cluster math required.
