Kubecost monitors and manages Kubernetes spend. It is installed into a cluster with a Helm chart, and lightweight agents on other clusters can send their data to the primary installation. It is aimed at platform and FinOps teams that want to see and optimise what their Kubernetes workloads cost. Kubecost's makers also created OpenCost, the open-source, vendor-neutral project that forms the core of the commercial offering.
IBM announced the acquisition of Kubecost on 17 September 2024 and planned to add it to its FinOps Suite, which includes Cloudability and Turbonomic. IBM is a US company, so the product now sits under a US parent, which is the relevant jurisdiction signal for European customers. The Helm chart repository is licensed under Apache 2.0, and the application runs inside your own Kubernetes cluster, so cost data can stay in your own infrastructure. The documentation reviewed does not state that a separate hosted service is required, and the vendor's own materials should be checked for any cloud-based features.
