Overview

OpenCost is an open-source standard for Kubernetes cost tracking. It provides real-time visibility into cloud spending by allocating costs to Kubernetes-native concepts like namespaces, deployments, and pods. It is the foundation for many commercial products, including Kubecost. As a free, community-driven tool, it offers flexibility and transparency but does not automate optimizations.

✨ Key Features

  • Real-time Kubernetes Cost Allocation
  • Cloud provider billing integration
  • Support for on-prem clusters
  • Open-source and vendor-neutral
  • Exportable data and API access

🎯 Key Differentiators

  • Completely free and open-source (Apache 2.0 license)
  • Vendor-neutral CNCF Sandbox project
  • Provides a foundational, standardized data model

Unique Value: Provides a no-cost, open, and extensible way to get started with Kubernetes cost monitoring, empowering teams to build their own FinOps practices.
