Secure

Billing, setup, and permissions are 100% handled via GitHub.

Immediate ROI

One subscription pays for itself by preventing costly misconfigurations before they deploy.

Cloud Costs Spiral Faster Than You Realize

Infrastructure changes come from the bottom up. Without a feedback loop, small changes turn into massive bills.

The Struggle

Surprise AWS Bills

Configuration changes silently add thousands to your monthly bill.

Too Late to Change

Refactoring expensive resources in production is risky and slow.

No Feedback Loop

Developers write code without knowing the financial impact.

Manual Estimation

Cost modeling in spreadsheets is tedious and quickly outdated.

Our Approach

The Solution

Pre-Deployment Estimates

See the exact dollar impact of every change inside your Pull Request.

Catch Issues Early

Prevent expensive mistakes before they ever reach production.

Automated FinOps

Continuous cost visibility baked directly into your CI/CD workflow.

Always Up-to-Date

Real-time pricing data for every resource you deploy.

Get Started in Three Simple Steps

CloudBurn integrates seamlessly with your existing GitHub workflow. Set it up once and get automated cost analysis on every pull request.

Install CloudBurn
Go to the GitHub Marketplace and click 'Install', then select the repositories where you manage AWS infrastructure.
Install CloudBurn GitHub App
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.
Install GitHub Action in your workflow
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:

Powerful Visibility from Day One

Installation is just the beginning. Once integrated, CloudBurn silently safeguards your budget and empowers your team to ship faster without financial risk.

Prevent Cloud Bill Surprises

Catch expensive infrastructure mistakes during code review, before they reach production and impact your budget.

Make Faster PR Decisions

Reviewers can approve or reject changes based on cost impact, not just code quality. No more guessing about infrastructure costs.

Team-Wide Cost Visibility

Every developer sees the cost impact of their infrastructure changes. Build a culture of cost awareness across your engineering team.

Shift FinOps Left

Cost optimization starts at development time, not after deployment. Make cost-effective decisions when changes are easiest to make.

Save Time on Manual Estimation

No more spreadsheets or manual AWS pricing lookups. CloudBurn automatically calculates costs for every infrastructure change.

Deploy with Confidence

Know exactly how infrastructure changes impact your monthly AWS bill. Deploy knowing you won't get surprised by the next invoice.

Frequently
asked questions

How do I install CloudBurn on my repositories?

Installing CloudBurn is simple. Visit the GitHub App installation page, select the repositories you want to analyze, and grant the necessary permissions. CloudBurn will automatically start analyzing infrastructure changes in pull requests. No code changes required.

What Infrastructure-as-Code tools does CloudBurn support?

CloudBurn currently supports AWS CDK (TypeScript) and Terraform. It automatically detects which IaC tool you're using and parses the diff accordingly. Support for CloudFormation native templates and additional languages is on our public roadmap.

How accurate are the cost estimates?

CloudBurn uses the official AWS Pricing API to calculate costs based on the actual resource properties extracted from your code (instance types, memory, CPU, storage). Estimates focus on 38 baseline cost resources with consistent hourly charges. While estimates are highly accurate for provisioned resources, actual costs may vary based on usage patterns and data transfer.

What GitHub permissions does CloudBurn need?

CloudBurn requires read access to pull requests and repository code to analyze infrastructure changes, and write access to post cost analysis comments on pull requests. We only access data necessary for cost analysis and don't store your source code permanently. See our Privacy Policy for details.

Is CloudBurn free? What does it cost?

CloudBurn is currently in beta and free to use. We're gathering feedback to improve the product. Pricing details for future paid tiers will be announced on our GitHub repository. Early adopters will receive special pricing benefits.

Do you offer FinOps consultancy beyond the CloudBurn tool?

Yes! CloudBurn is built by Towards the Cloud, a cloud consultancy specializing in AWS infrastructure. We offer hands-on cost optimization and FinOps consulting services to help teams reduce cloud spend and implement sustainable cost management practices. Contact us to learn more.
