OpenCost: Cost And Resource Management
summary
OpenCost delivers a unified allocation model that produces per-container and per-node cost metrics for cloud and on‑prem Kubernetes, using a Prometheus backend today and a Promless mode (alpha) to address scale limits. It exposes an MCP server with APIs and a demo UI that can return top‑5 expensive namespaces or deployments, supports plugins (DataDog, Snowflake), lacks OSS network billing (data structures exist), and proves useful for right‑sizing, autoscaling, and internal chargeback.
