AWS FinOps report orchestrator

CostHive

Point it at an AWS account and get a money-first cost-optimization report from best-in-class open-source FinOps tools — no manual tool wrangling. The cost-focused sibling to SentryHive. It merges output from six different FinOps tools into one dollar-ranked report, so the headline is a single number — total estimated monthly savings — instead of six dashboards to cross-reference. Beyond live-account scanning, it also estimates costs before deployment from Terraform, CDK, or CloudFormation, and allocates Kubernetes/EKS spend down to the namespace and workload.

Highlights

  • One headline number: total estimated monthly savings, broken down by category with quick wins called out
  • Cross-account scans plus pre-deploy IaC cost estimates and EKS/Kubernetes cost allocation
  • Read-only and dry-run by default — no data leaves your machine
  • Single Docker image — no six-dashboard reconciliation
