Cloud Costs Spiral Faster Than You Realize

Infrastructure changes come from the bottom up. Developers create and modify resources daily, but there's no feedback loop between writing code and understanding costs. Before you know it, your AWS bill has doubled and optimization becomes a painful project.

💸 Surprise AWS Bills

You merge infrastructure changes without knowing the cost impact. A simple configuration change can unexpectedly add thousands to your monthly bill, and you only find out weeks later.

⏰ Too Late to Change

Once infrastructure is in production, changes become risky and time-consuming. Refactoring for cost requires downtime, testing, and coordination across teams.

🤷 No Cost Feedback Loop

Developers deploy infrastructure without understanding costs. Manual cost estimation is tedious and often inaccurate. Small incremental changes silently add up to massive expenses.

The window to make cost-effective decisions closes quickly once infrastructure reaches production...

What You Get with CloudBurn

CloudBurn transforms how your team thinks about cloud costs by providing instant feedback at the exact moment decisions are made.

💸 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.
