See AWS costs in your pull requests before deploying to production.
CloudBurn analyzes your Terraform or AWS CDK infrastructure changes and automatically posts cost estimates in pull requests. Catch expensive mistakes during code review instead of discovering them weeks later on your AWS bill.
- Automatic cost analysis on every PR with infrastructure changes
- Real-time AWS pricing based on your infrastructure's region
- Resource-by-resource breakdown showing old vs new monthly costs
- Smart filtering - only shows resources with actual cost impact (VPC, IAM, security groups filtered out)
Here's what CloudBurn posts in your PR:
| Resource | Current cost | New monthly cost |
|---|---|---|
| MySecondInstance | $0.00 | $133.15 (+$133.15, new) |
| MyThirdInstance | $0.00 | $66.58 (+$66.58, new) |
| firstTaskDef | $0.00 | $9.01 (+$9.01, new) |
| MyFirstInstance | $0.00 | $8.32 (+$8.32, new) |
Overall monthly cost change: +$217.06

Step 1: Install CloudBurn
Click "Install" and select the repositories where you manage AWS infrastructure.
Step 2: Install the GitHub Action
CloudBurn needs your infrastructure diff/plan output to calculate costs. Install the companion action for your tool:
- Terraform: Terraform Plan PR Commenter (docs)
- AWS CDK: AWS CDK Diff PR Commenter (docs)
These actions post your terraform plan or cdk diff output as a PR comment, which CloudBurn then analyzes.
Step 3: Create a Pull Request
Open a PR with infrastructure changes and CloudBurn automatically posts cost analysis within seconds.
- You open a PR with Terraform or CDK changes
- GitHub Action posts the infrastructure diff/plan as a comment
- CloudBurn detects the diff, analyzes it using real-time AWS pricing
- Cost report appears in your PR showing exactly what each change costs
