CloudBurn installs statistics

Get automatic AWS cost estimates in your pull requests before deploying to production. CloudBurn analyzes your cdk diff or terraform plan output and shows you exactly how much your infrastructure changes will cost per month.

Key benefits

• Catch expensive mistakes during code review, not after deployment • See real-time cost impact of every infrastructure change • No more billing surprises at the end of the month

Getting Started

Step 1: Install the CloudBurn GitHub App

• Click "Install" and select the repositories where you manage AWS infrastructure • Grant the necessary permissions (read access to PRs, write access to post comments)

Step 2: Add the GitHub Action to Your Workflow

Choose the action that matches your infrastructure-as-code tool:

• For AWS CDK: Install the AWS CDK Diff PR Commenter action • For Terraform: Install the Terraform Plan PR Commenter action

Follow the installation instructions on the action page to add it to your GitHub workflow. The action will capture your cdk diff or terraform plan output and send it to CloudBurn for analysis.

Step 3: Create a Pull Request

Open a PR with infrastructure changes and CloudBurn will automatically:

• Detect the diff/plan output from your GitHub Action • Analyze the changes and calculate cost impact • Post a detailed cost report as a PR comment within seconds like the example below:
