## What it is
CloudBurn is an open-source AWS cost policy engine distributed as a CLI, SDK, and GitHub App. It runs deterministic cost rules against Terraform and CloudFormation templates in CI (scan) and against live AWS accounts (discover) to catch and remediate wasteful spending patterns.

## Use cases
- scan terraform templates for aws cost waste before deploy
- find cost savings in my live aws account
- add cost checks to ci pipeline for pull requests
- flag s3 buckets missing lifecycle policies
- detect ec2 instances not using gravon or preferred instance types
- audit rds and ebs for outdated expensive storage types
- embed aws cost rules in custom tooling via sdk
- see cost impact of terraform plans on pull requests

## When to choose
- you want deterministic, inspectable cost rules instead of dashboard-first finops tools
- your infrastructure is defined in terraform or cloudformation on aws
- you want cost feedback at code review and ci time before deployment
- you need to audit an already-running aws account for waste
- you prefer an open-source cli you can self-host and script

## When to avoid
- you need multi-cloud cost management across azure and gcp in depth (aws is the focus)
- you want usage-based anomaly detection or forecasting rather than deterministic rules
- you need a full finops dashboard with budgeting and reporting for finance teams
- your stack is not on aws
