CloudBurn

CloudBurn is the lightning-fast FinOps shield engineered for modern development teams. It eliminates the painful, costly lag between deploying infrastructure and discovering its financial impact. Built specifically for developers and platform engineers using Terraform or AWS CDK, CloudBurn integrates directly into your GitHub workflow to deliver real-time AWS cost estimates the moment a pull request is opened. This transforms reactive bill-shock into proactive, actionable cost intelligence. By analyzing your infrastructure-as-code diffs against live AWS pricing data, it posts a detailed, line-item cost report directly into the PR conversation within seconds. This creates an immediate feedback loop, empowering your team to discuss, debate, and optimize costs during code review—when changes are trivial and free. It prevents expensive misconfigurations from ever reaching production, turning every engineer into a cost-conscious builder. CloudBurn delivers an immediate return on investment by safeguarding your cloud budget from day one, shifting cost visibility left and stopping financial surprises before they spiral.

Real-Time Pull Request Cost Analysis

CloudBurn provides instant AWS cost estimates directly within your GitHub pull requests. The moment a PR with infrastructure changes is opened, CloudBurn automatically analyzes the IaC diff, calculates the precise monthly cost impact using live AWS pricing, and posts a comprehensive report as a comment. This gives developers immediate visibility into the financial consequences of their code before merge, enabling cost optimization as part of the standard review process.

Live AWS Pricing Integration

Forget outdated spreadsheets and manual estimates. CloudBurn pulls real-time, accurate pricing data directly from AWS for every resource in your Terraform or CDK stack. This ensures your cost projections reflect the latest on-demand rates, reserved instance discounts, and regional pricing variations, giving you confidence that the numbers you see are correct and actionable for making informed architectural decisions.

Seamless GitHub Native Integration

Setup is fast and secure, with billing, permissions, and installation handled 100% through GitHub. After a quick install from the GitHub Marketplace, CloudBurn works silently in the background. It connects to your chosen GitHub Action for CDK diff or Terraform plan output, requiring no complex configuration or sensitive credential management outside your existing ecosystem, minimizing friction and security overhead.

Detailed Line-Item Cost Breakdown

CloudBurn goes beyond a simple total. Its PR reports break down the cost impact per resource, showing current cost, new cost, and the delta. Each resource includes a detailed description with the exact hourly price and AWS usage type. This granularity helps teams instantly identify which specific change is driving cost increases, facilitating targeted discussions on optimization and alternative configurations during review.

Preventing Costly Production Misconfigurations

Catch architectural mistakes with a high price tag before they deploy. A developer might accidentally specify a t3.xlarge instance instead of a t3.micro. CloudBurn flags this as a +$133 monthly change in the PR, prompting an immediate review and correction. This prevents heart-stopping AWS bills and eliminates the risky, time-consuming refactoring required to fix such errors in a live environment.

Enabling Proactive FinOps Culture

Shift financial accountability left in the development cycle. CloudBurn makes cost a first-class metric in every infrastructure code review, alongside performance and security. Engineering teams can debate the cost/benefit of a new database instance or a more powerful compute option in the PR, fostering a culture of cost-awareness and collective ownership over the cloud budget from the very first line of code.

Streamlining Architecture Review & Approval

Platform and FinOps teams can scale their governance without becoming a bottleneck. Instead of manually reviewing every Terraform plan, they can set policies and rely on CloudBurn's automated reports to surface high-cost changes for attention. This accelerates developer velocity for standard changes while ensuring guardrails are in place, making the review process faster and more data-driven.

Optimizing Existing Infrastructure

Use CloudBurn for proactive cost management on live systems. By creating a pull request that modifies existing resources—like downsizing instance types or adjusting auto-scaling parameters—teams can see the projected monthly savings before applying the change. This de-risks optimization efforts and provides clear, pre-approval financial justification for infrastructure improvements.

How does CloudBurn calculate costs?

CloudBurn calculates costs by analyzing the output of your cdk diff or terraform plan command, which is captured by a GitHub Action. It identifies the resources being added, modified, or destroyed, then fetches the current, on-demand pricing for those specific resources and configurations from the official AWS Price List API. It runs this calculation for a standard 730-hour month to provide a clear monthly estimate for the proposed changes.

Is my code or cloud configuration data secure?

Yes. CloudBurn is built with security as a priority. The integration is 100% handled through GitHub—you install it via the GitHub Marketplace. CloudBurn does not require direct access to your AWS accounts or sensitive credentials. It only receives the diff/plan output you choose to send via the GitHub Action, and all communication is secured. Billing and permissions are also managed entirely through GitHub's secure systems.

What IaC tools and cloud providers does CloudBurn support?

Currently, CloudBurn provides deep, native integration for AWS cloud infrastructure. It supports the two most popular infrastructure-as-code frameworks for AWS: HashiCorp Terraform and the AWS Cloud Development Kit (AWS CDK). You can use the dedicated GitHub Actions provided for each tool to seamlessly integrate CloudBurn into your CI/CD pipeline for automated cost reporting.

Can I try CloudBurn before committing to a paid plan?

Absolutely. You can start using CloudBurn for free with its Community plan. Additionally, you can experience all the advanced Pro features with a full 14-day free trial, no credit card required. You can cancel the trial at any time, or simply continue using the feature-rich Community plan forever if it meets your needs. This lets you fully evaluate its ROI and fit within your team's workflow risk-free.
