Show HN: I'm building a cloud cost tool for Terraform

Hi HN, author here. I'm looking for feedback from devs/devops engineers on the tool in general as well as:

1. What is your biggest pain point with cloud costs?

2. Any ideas on how to handle non-baseline costs? - data transfer costs and other usage-based costs are often a significant portion of the bill and are also the hardest to predict and track down.
