CloudBurn

CloudBurn is the essential early-warning system for your cloud infrastructure, designed to stop budget-busting AWS bills before they ever happen. In the fast-paced world of modern DevOps, where infrastructure is defined as code with tools like Terraform and AWS CDK, a single misconfigured resource can silently add thousands to your monthly invoice. Traditional cost monitoring tools act as an autopsy report, showing you the damage weeks after deployment when it's too late and expensive to change. CloudBurn flips this model on its head. It integrates directly into your GitHub CI/CD workflow to provide real-time, pre-deployment cost analysis for every pull request. By automatically posting a detailed cost impact report on each PR, it empowers developers and engineering teams to see the exact financial consequences of their code changes. This creates a powerful culture of cost accountability, shifting FinOps left and making cost awareness a non-negotiable part of the code review process. For engineering leaders, CloudBurn delivers immediate ROI by preventing costly misconfigurations from ever reaching production, ensuring infrastructure decisions are informed, optimized, and aligned with business budgets from the very first commit.

Pre-Deployment Cost Estimation

CloudBurn provides precise, line-item cost estimates for infrastructure changes before they are merged and deployed. By analyzing the output of cdk diff or terraform plan directly within your GitHub Actions workflow, it calculates the projected monthly cost impact and posts it as a comment on your pull request. This gives every team member immediate visibility into whether a change adds $10 or $10,000 to the bill, enabling proactive cost optimization during the review phase.

Automated GitHub PR Integration

The tool operates seamlessly within your existing developer workflow with zero manual overhead. Once installed from the GitHub Marketplace and configured via a simple GitHub Action, CloudBurn automatically triggers on every relevant pull request. It detects infrastructure changes, performs its analysis, and posts the comprehensive cost report as a bot comment—all within seconds, without developers needing to leave their familiar GitHub environment.

Real-Time AWS Pricing Data

CloudBurn's estimates are powered by always up-to-date, real-time AWS pricing data. It doesn't rely on stale spreadsheets or manual price lookups. The engine accurately calculates costs for a vast array of services (like EC2, RDS, Fargate) and instance types across all AWS regions, ensuring that the financial projections you see are accurate and reflective of the current market, giving you complete confidence in the data.

Detailed Cost Breakdown & Visibility

Beyond a simple total, CloudBurn delivers a granular, resource-by-resource breakdown of cost changes. The PR comment clearly lists each affected resource (e.g., MySecondInstance), its current cost, its new projected cost, and the delta. It even includes details like the hourly rate and AWS usage type, providing unparalleled transparency and educating developers on what drives their cloud spend.

Preventing Costly Configuration Errors

Catch simple but expensive mistakes like accidentally provisioning a dozen t3.xlarge instances instead of t3.micro, or deploying a development stack to the wrong, more expensive region. CloudBurn acts as a safety net, flagging these high-cost diffs directly in the PR where they can be corrected instantly, preventing heart-stopping bills and the risky, time-consuming process of refactoring in production.

Enabling Developer-Led FinOps

Foster a culture of cost ownership and accountability within engineering teams. By making cost impact a visible and routine part of every code review—just like security scans or unit tests—CloudBurn empowers developers to make cost-conscious architectural decisions. They can compare the cost of different instance types or service configurations and choose the most efficient option before shipping code.

Streamlining Infrastructure Code Reviews

Provide critical financial context to peer reviewers and engineering managers. When reviewing a complex infrastructure change, the accompanying CloudBurn report answers the crucial question: "What is the financial impact of this change?" This allows for more informed approval decisions, ensures changes align with project budgets, and significantly improves the quality and thoroughness of infrastructure reviews.

Optimizing CI/CD Pipeline Efficiency

Integrate proactive cost governance directly into your automated deployment pipelines. CloudBurn can be configured as a required check, allowing teams to set cost thresholds or policies. This enables automated gates that can block or flag PRs that exceed certain cost limits, ensuring financial guardrails are enforced automatically and consistently across all projects and teams.

How does CloudBurn calculate the cost estimates?

CloudBurn calculates estimates by parsing the infrastructure-as-code diff (from Terraform Plan or AWS CDK Diff) generated in your GitHub Action. It identifies the specific AWS resources being added, modified, or removed, then queries real-time AWS pricing data for those services, instance types, and regions. It combines this with assumed runtime (730 hours for a full month) to project the monthly cost impact, providing a highly accurate forecast.

What infrastructure-as-code tools does CloudBurn support?

CloudBurn currently provides native, seamless integration for the two most popular IaC frameworks: HashiCorp Terraform and AWS Cloud Development Kit (CDK). Support is implemented via dedicated GitHub Actions (Terraform Plan PR Commenter and AWS CDK Diff PR Commenter) that capture the plan/diff output and send it to CloudBurn for analysis.

Is my code or cloud configuration data secure with CloudBurn?

Yes, security is a foundational principle. CloudBurn is installed via the official GitHub Marketplace and uses standard GitHub OAuth for authentication. Your actual Terraform or CDK code is processed securely, and the tool only requires read access to pull requests and the ability to post comments. Crucially, CloudBurn never requires or stores your AWS credentials; cost calculation is done using its own secure pricing service.

Can I try CloudBurn before committing to a paid plan?

Absolutely. CloudBurn offers a 14-day Pro Trial that gives you full access to all Pro features at no cost, with no credit card required to start. You can cancel anytime during the trial. After the trial, you can choose a paid plan or continue using the feature-limited Community plan for free forever, making it risk-free to integrate and validate its value for your team.
