Spendemon is a Next.js dashboard for monitoring Kubernetes resource footprint and estimating workload cost from Prometheus metrics. It connects to one or more Prometheus endpoints, discovers clusters, namespaces, and pods, then layers in configurable pricing rates to produce cost snapshots by cluster, namespace, and individual pod. Costs can be exported as CSV or JSON, and shared infrastructure namespaces can be distributed proportionally across workload namespaces.
