  • Detects over-provisioned CPU and memory in Kubernetes clusters, typically by 30-60%.
  • Analyzes pod resource configurations to identify gaps between set limits and actual needs.
  • Estimates cost waste, with an example showing $14,880 annual waste detected.
  • Breaks down waste by category: Memory, CPU, and orphaned Load Balancers.
  • Identifies the biggest waster, e.g., 'api-gateway' pod wasting $8,400/year.
  • Provides fixes like adjusting memory requests to match actual usage.
  • Lists common issues: Over-provisioned memory/CPU, orphaned load balancers, unbound volumes.
  • Uses read-only kubectl commands for analysis, requiring metrics-server for accurate usage data.
  • Offers dashboard features for detailed analysis, historical trends, and PDF export.
  • Operates locally with optional data push to dashboard; no agents installed.
  • Uses conservative cloud pricing averages for cost estimation.
  • Supports disabling telemetry and is open source, encouraging community contributions.
