CloudBurn

CloudBurn is your team's financial safety net for cloud infrastructure. It's a specialized tool designed for engineering teams using Infrastructure-as-Code (IaC) tools like Terraform or AWS CDK. Its core mission is to prevent budget-busting surprises by bringing cost awareness directly into the developer workflow. The problem it solves is all too common: a developer merges a pull request, the new resources deploy, and weeks later, the finance team is staring at a shocking AWS bill, wondering what changed. By then, it's costly and risky to fix. CloudBurn stops this cycle by providing real-time, automated cost analysis for every infrastructure change before it's merged. When a pull request is opened, CloudBurn automatically calculates the exact dollar impact of the proposed changes and posts a clear, detailed report as a comment. This empowers developers and reviewers to have informed discussions about cost versus performance upfront, fostering a culture of proactive cost management (FinOps) and preventing expensive misconfigurations from ever reaching production.

Automated Pull Request Cost Analysis

CloudBurn seamlessly integrates with your GitHub workflow to provide instant cost visibility. Whenever a developer opens a pull request with changes to Terraform or AWS CDK code, CloudBurn automatically springs into action. It analyzes the infrastructure diff, calculates the monthly cost impact using real-time AWS pricing, and posts a comprehensive report directly in the pull request thread. This automation makes cost review a natural, non-disruptive part of the code review process, ensuring no change slips through without financial scrutiny.

Real-Time AWS Pricing Data

Your cost estimates are always accurate and up-to-date. CloudBurn doesn't rely on stale, manual price lists or spreadsheets. It pulls pricing information directly from AWS, ensuring that every cost calculation in your pull request reflects the latest on-demand rates for services like EC2, Fargate, RDS, and more. This means you can trust the numbers you see, whether you're provisioning a new t3.micro instance or scaling up to a memory-optimized RDS cluster.

Detailed and Actionable Cost Reports

The tool provides clear, line-item breakdowns so you know exactly what's driving costs. A CloudBurn report doesn't just show a total; it lists each affected resource, its current cost, its new projected monthly cost, and the delta. It even breaks down the hourly rate and usage type, as shown in examples with EC2 instances and Fargate tasks. This granularity helps teams pinpoint expensive resources and have productive conversations about optimizing architecture or choosing more cost-effective alternatives before code is merged.

Secure GitHub-Centric Integration

Setup is simple and security is handled by the platform you already trust. CloudBurn is installed directly from the GitHub Marketplace and uses GitHub's robust permission system. There's no need to share sensitive AWS credentials or set up complex billing integrations. The tool operates securely within your GitHub environment, analyzing the plan or diff output from your existing CI/CD actions, which keeps your cloud account access secure and streamlined.

Preventing Costly Configuration Errors

Catch simple mistakes that lead to massive bills. A common error is accidentally changing an instance type from a t3.small to a much more expensive c5n.18xlarge in a Terraform module. Without CloudBurn, this might go unnoticed until the bill arrives. With it, the pull request immediately flags a monthly cost increase of thousands of dollars, prompting the team to correct the typo and save significant money.

Enabling Proactive Architecture Reviews

Facilitate better design decisions during code review. When a team proposes a new microservice using AWS Fargate, reviewers can discuss the cost implications of CPU and memory settings in real-time. CloudBurn's report provides the data needed to balance performance requirements with budget constraints, encouraging teams to choose the most efficient resource sizing from the start, rather than over-provisioning "to be safe."

Streamlining FinOps and Budget Governance

Embed financial accountability directly into engineering teams. CloudBurn acts as an automated gatekeeper, ensuring cost considerations are part of every infrastructure change. This empowers developers to own the cost impact of their code and helps platform or FinOps teams enforce policies without being a bottleneck. It creates a scalable, collaborative approach to cloud financial management.

Optimizing Existing Infrastructure

Use cost analysis for refactoring and cleanup initiatives. When planning to decommission old resources or migrate to newer, cheaper instance types, teams can open a pull request and use CloudBurn's report to quantify the expected savings. This provides clear, documented proof of ROI for cleanup efforts and helps prioritize which projects will have the biggest positive impact on the cloud bill.

How does CloudBurn calculate costs?

CloudBurn calculates costs by analyzing the output of your infrastructure tool's planning command—like terraform plan or cdk diff. It extracts the resource changes from this output and then queries the official AWS Price List API to fetch the current, on-demand hourly rates for those specific services and configurations in your region. It then extrapolates these hourly costs to a monthly estimate (based on 730 hours) to give you a clear picture of the recurring financial impact.

Is my AWS billing data or access key shared with CloudBurn?

No, CloudBurn does not require access to your AWS billing data or your AWS account access keys. The integration is secure and GitHub-centric. Cost calculation is performed using publicly available AWS pricing data. Your team's specific infrastructure configuration is sent securely from your GitHub Actions workflow to CloudBurn's service for analysis, but this does not include any live AWS credentials or direct access to your account.

What Infrastructure-as-Code tools does CloudBurn support?

Currently, CloudBurn provides dedicated support for two of the most popular IaC tools: HashiCorp Terraform and the AWS Cloud Development Kit (CDK). The setup involves adding a specific GitHub Action to your repository's workflow that is designed to capture the plan or diff output from either of these tools and send it for analysis.

Can I try CloudBurn before committing to a paid plan?

Absolutely! CloudBurn offers a free Community plan to get started. They also provide a 14-day trial of the Pro plan, which gives you full access to advanced features at no cost. You can begin using it without a credit card, and you can cancel the Pro trial at any time or simply continue using the free Community plan features forever if they meet your needs.
