OpenCost is a CNCF incubating, vendor-neutral open source tool for real-time Kubernetes and cloud cost monitoring and allocation. It provides a cost specification plus a Go implementation that exposes pricing data via REST APIs, a web UI, and Prometheus metrics.

Use cases

• monitor kubernetes workload costs per namespace, pod, or controller
• allocate cloud spend across teams for showback and chargeback
• track aws, azure, and gcp cloud costs in one place
• export kubernetes pricing data to prometheus
• price on-prem kubernetes clusters with custom csv rates
• track ai inference costs for vllm deployments

When to choose

• you run kubernetes and need per-namespace or per-pod cost visibility
• you want vendor-neutral, open source finops tooling with prometheus integration
• you need multi-cloud cost allocation across aws, azure, and gcp
• you operate on-prem clusters and need custom pricing support

When to avoid

• you need full enterprise finops features like advanced forecasting or savings recommendations
• you are not running kubernetes or cloud infrastructure
• you want a fully managed hosted cost solution without self-hosting
