About Zerobillbot

Zerobillbot was born from a frustrating reality: cloud bills that surprise you at the end of the month. As engineers who've worked on infrastructure at startups and large organizations, we've seen teams accidentally deploy NAT Gateways, oversized instances, and forgotten resources that quietly burn thousands of dollars.

The problem isn't that teams don't care about costs — it's that cost information isn't surfaced where decisions happen: in the pull request.

We built Zerobillbot to bridge that gap. By analyzing infrastructure-as-code changes at code review time, we give every engineer — not just the FinOps team — the ability to see and control infrastructure costs before they're incurred.

To keep that signal trustworthy, we continuously benchmark provider coverage with reproducible AWS, Azure, and GCP templates and compare comment output against expected baselines.
