## What it is
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
