CloudCostCompareTerraform plan estimate
Upload a Terraform plan as JSON and see what the AWS resources in it cost per month at on-demand list prices. Resources the catalog cannot price are listed as "Not priced" with the reason and left out of the total, and the total is then marked partial.
Create the file with terraform plan -out plan.out and then terraform show -json plan.out > plan.json. The plan is read in your browser and is never uploaded.
What is priced today: EC2 instances (Linux, shared tenancy) and their volumes, EBS volumes, and RDS for PostgreSQL (instance and storage, Single-AZ or Multi-AZ). Everything else, including S3, Lambda, load balancers and resources from other clouds, is listed but not priced. Only AWS is in the price catalog so far.
