OpenCost

OpenCost is an open-source, vendor-neutral project designed to provide real-time visibility into Kubernetes and cloud infrastructure spending. It enables DevOps teams and financial stakeholders to accurately allocate costs across clusters, namespaces, and labels. By integrating directly with Prometheus, it offers a standardized specification for monitoring expenses across major cloud providers. Its primary differentiator is its commitment to open-source transparency, allowing organizations to avoid vendor lock-in while gaining granular insights into their cloud-native resource consumption and optimizing overall infrastructure efficiency for complex, distributed environments.
