When to Choose Each
Choose KorPro if you:
- Need to find and clean up unused resources (ConfigMaps, Secrets, PVCs, Services)
- Want read-only access with zero production risk
- Suspect your clusters have accumulated waste over time
- Need security assessment of orphaned Secrets and RBAC bindings
- Require an audit-first approach — review before any changes
Choose CAST AI if you:
- Want automated node optimization and instance type selection
- Need spot instance management with automatic fallback
- Want automated pod right-sizing based on actual usage
- Are comfortable with an agent that has write access to your infrastructure
- Have variable workloads that benefit from dynamic scaling
Better Together
KorPro and CAST AI address different layers of Kubernetes cost optimization. For maximum savings, use KorPro first to remove orphaned resources, then deploy CAST AI to optimize the infrastructure running your active workloads.

Frequently Asked Questions
Can I use both KorPro and CAST AI together?▼
Yes! They are complementary tools. KorPro removes orphaned resources (waste), and CAST AI optimizes the infrastructure running your active workloads (efficiency). Using both together delivers the highest total savings.
Which tool should I deploy first?▼
Start with KorPro. Removing unused resources first means CAST AI won't waste effort optimizing infrastructure that serves orphaned workloads. Cleanup is also lower risk since KorPro uses read-only access and an audit-first approach.
Does CAST AI detect unused Kubernetes resources?▼
No. CAST AI focuses on infrastructure optimization — node types, spot instances, autoscaling, and pod right-sizing. It does not detect orphaned ConfigMaps, Secrets, PVCs, Services, or other unused Kubernetes objects. That's where KorPro fills the gap.
Which tool requires less cluster access?▼
KorPro requires only read-only RBAC permissions. Its Inspector agent scans resources without modifying anything. CAST AI requires write access because it actively creates and terminates nodes, modifies pod resources, and manages infrastructure.
