**Infracost** reads the plan or the code, looks up cloud prices and prints a cost breakdown per resource. In CI it comments the cost change on each pull request, a core practice of [FinOps](https://www.itwonderlab.com/aws-cost-optimization-finops/).

### Key concepts

- **Breakdown**: cost per resource.
- **Diff**: the change against the base branch.
- **Usage file**: estimates for pay-per-use items.
