Feature Comparison
CloudBurn
Real-Time Pre-Deployment Cost Analysis
CloudBurn provides instant, automated cost analysis for every infrastructure change directly in your pull requests. Using live AWS pricing data, it calculates the exact monthly cost impact of your Terraform or CDK diff and posts a detailed, line-item report as a comment within seconds. This allows your team to see the financial consequences of a new t3.xlarge instance or Fargate task definition before a single resource is provisioned, preventing surprises.
Seamless GitHub Integration
Get started in minutes with a 100% GitHub-native experience. Simply install CloudBurn from the GitHub Marketplace, add the corresponding GitHub Action to your workflow, and you're done. Billing, setup, and permissions are handled securely through GitHub, requiring no separate dashboard logins or complex IAM configurations. It integrates directly into the tools developers already use every day.
Automated FinOps Guardrails
CloudBurn transforms your CI/CD pipeline into an automated FinOps enforcement point. It acts as a proactive guardrail, catching expensive misconfigurations—like accidentally deploying a production-grade database in a dev environment—before they can spiral into a five-figure AWS bill. This creates a powerful, automated feedback loop that makes cost optimization a natural part of the development lifecycle.
Live AWS Pricing Data
Forget outdated spreadsheets and manual estimations. CloudBurn's estimates are powered by real-time AWS pricing data, ensuring accuracy for every region and service. Whether you're deploying EC2 instances, RDS databases, or Lambda functions, you get an up-to-the-minute cost breakdown for each resource, so your team can make informed decisions based on current market rates.

Use Cases
CloudBurn
Preventing Costly Developer Mistakes
Catch simple, expensive errors before they deploy. A developer might accidentally change an instance type from t3.micro to t3.xlarge, unknowingly adding over $130 to the monthly bill. CloudBurn flags this in the PR review, allowing the team to catch and correct it immediately, turning a potential budget disaster into a minor code comment.
Enabling Proactive Architecture Reviews
Facilitate data-driven architecture discussions during code review. When a team proposes a new microservice using Fargate, CloudBurn provides the concrete monthly cost, allowing architects and engineers to weigh the benefits against the expense and optimize the resource allocation (e.g., CPU/memory settings) collaboratively before any commitment is made.
Streamlining FinOps for Engineering Teams
Empower developers to own cloud costs without becoming pricing experts. CloudBurn bakes financial accountability directly into the developer workflow, providing the context needed at the exact moment a decision is made. This shifts the culture from reactive bill-shock to proactive cost management, making every engineer a cost-conscious architect.
Gaining Visibility into Infrastructure Drift
Track the cumulative financial impact of infrastructure changes over time. As multiple pull requests merge throughout a sprint, small cost increments can add up silently. CloudBurn provides a clear audit trail of cost decisions per PR, helping teams understand how their infrastructure evolution directly impacts the monthly cloud spend.
