The bill before you deploy

Price your Terraform code or plan at on-demand list prices, see what a plan changes on a diagram, and see what your local setup would cost.

localhost:7644/_pogi/

The problem

A cloud bill arrives after you deploy. pogi reads your Terraform and shows the monthly price first, on your machine, with no account.

How it works

  1. 01

    Price a folder or a plan

    pogi reads your .tf files itself and never runs Terraform. Give it a plan.json instead, and it uses the values Terraform worked out, and shows each resource's price before and after.

    pogi cost plan.json

    See what a plan changes

    The Terraform page draws your resources and what uses what. With a plan, each box takes the colour of what the plan does to it: create, update, replace or delete.

    localhost:7644/_pogi/
    The console's Terraform page for a plan: $199.57 a month after the plan. Boxes: db and web to create, the queue jobs to update, the queue old to delete, and the topic events unchanged, with a dotted subscription line to jobs.

    See what runs in pogi

    The Cost page works out a monthly bill from the resources you made and the traffic your code sent. Run your tests first: the traffic part is a rate, so a very short run is a poor guide.

    localhost:7644/_pogi/
    The console's Cost page: an estimated monthly cost of $0.65, split into S3 at $0.26, SNS at $0.23 and SQS at $0.16, all of it on AWS.

What to know

  • The prices are on-demand list prices for 730 hours a month, with no free tier and no discount.
  • A resource pogi has no price for shows as "not priced" and adds nothing, so the real bill could be higher.
  • Some prices depend on use, such as requests or data moved. Without a usage file, pogi shows the unit price and counts $0.
  • A value that only exists after apply is assumed, and the row says so.
