Infracost
Infracost estimates the cost impact of Infrastructure as Code changes, usually by reading Terraform plan output and showing the expected monthly difference.
Infracost adds cost feedback to infrastructure changes. It reads a Terraform plan and estimates how much the proposed resources will cost each month.
That makes it useful in pull requests and deployment pipelines. A change from a small VM to a large one is no longer buried inside a plan file; the cost difference can be shown before anyone clicks approve.
It is still an estimate. Discounts, reserved instances, credits, region-specific pricing, and odd billing rules can all move the real bill. The point is not perfect accounting. The point is to catch expensive surprises while they are still code.
