What is OpenCost?
OpenCost provides flexible and customizable cost allocation and cloud resource monitoring specifically designed for Kubernetes and cloud-native environments. It enables accurate showback, chargeback, and ongoing reporting by breaking down costs to the container level within Kubernetes.
The tool integrates with major cloud providers like AWS, Azure, and GCP to pull dynamic asset pricing via their billing APIs. It also supports on-prem Kubernetes clusters through custom pricing configurations. OpenCost monitors costs for in-cluster resources such as CPU, GPU, memory, load balancers, and persistent volumes, as well as out-of-cluster cloud provider resources like object storage, databases, and other managed services. It is an open-source project supported by a community of Kubernetes experts and practitioners, and is an incubating project of the Cloud Native Computing Foundation.
