Infracost supports over 1,100 Terraform resources across AWS, Azure and Google. That number is growing fast thanks to our large open source community of contributors.

The quickest way to find out if your Terraform resources are supported is to run infracost breakdown with the --show-skipped flag. This shows the unsupported resources at the bottom of the output

You could also run the following command to only see the unsupported resources: infracost breakdown --path . --format=json | jq ".summary.unsupportedResourceCounts"

The resource I want isn't supported

We regularly add support for new resources so we recommend watching our repo for releases: goto the repo page, click on the Watch button > select Custom > Releases and click on Apply.

You can help by:

  1. Creating an issue and mentioning the resource names you need; we'll try to prioritize it depending on the community feedback.
  2. Contributing to Infracost. You can join our community Slack channel if you need help contributing.

We plan to add support for other IaC tools such as Pulumi, AWS CloudFormation/CDK and Azure ARM/Bicep. Please 👍 them if you'd like us to work on them sooner.

My cost estimate looks wrong

Please create an issue and provide the Terraform resource code that can be used to reproduce the issue. If possible, also include any relevant billing data from the cloud vendor that might help us troubleshoot.
