How does CloudBurn calculate the cost estimates?

CloudBurn calculates estimates by parsing the infrastructure change plan (from terraform plan or cdk diff) and querying the official AWS Pricing APIs in real-time. It uses the resource specifications, region, and intended usage patterns defined in your IaC code to fetch the most current On-Demand pricing. The tool then computes the projected monthly cost based on 730 hours of usage (24/7 operation) to provide a standardized, comparable figure for review.

Is my code or cloud credentials exposed to CloudBurn?

No, CloudBurn follows a secure, GitHub-centric model. Your IaC code never leaves your GitHub repository. The analysis is triggered by a GitHub Action within your own workflow, which sends only the textual output of the diff/plan command (which contains resource types and configurations, not secrets) to CloudBurn's analysis engine. Your AWS credentials remain entirely within your GitHub environment and are never shared with CloudBurn.

What IaC tools and cloud providers does CloudBurn support?

Currently, CloudBurn provides native and dedicated support for the two most prevalent Infrastructure-as-Code tools: HashiCorp Terraform and AWS Cloud Development Kit (CDK). The platform is designed for AWS cloud infrastructure, as it leverages AWS's own pricing APIs. Support for additional cloud providers like Microsoft Azure or Google Cloud Platform would depend on future development and customer demand.

Can CloudBurn show cost savings from deleting or modifying resources?

Yes, absolutely. CloudBurn's analysis is based on the diff between the current and proposed infrastructure state. If a pull request modifies a resource to a cheaper alternative or deletes a resource entirely, the cost report will clearly show a negative cost change, highlighting the projected monthly savings. This makes it valuable for optimization and cleanup initiatives, not just for reviewing new deployments.

How does diffray's accuracy compare to other AI code review tools?
