I kept seeing the same pattern: engineers ship a Terraform PR on a Friday, and by Monday the cloud bill has jumped $800. Not because anyone made a bad decision but because no one had cost visibility at the point where it actually mattered: code review.

So I built Zerobillbot a GitHub (and GitLab) app that analyzes infrastructure-as-code changes in every pull request and posts a detailed cost breakdown before the merge. AWS, Azure, and GCP. Terraform, CloudFormation, ARM all supported, zero config needed.

You can even set thresholds to block merges that would blow your budget. Finance teams love it. DevOps teams don't get surprise conversations on Monday morning.

Would love to connect with anyone in DevOps, platform engineering, or cloud cost management. Always open to feedback! zerobillbot.com
