Feature Comparison

CloudBurn

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Forget outdated spreadsheets and manual estimates.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.

diffray

Multi-Agent Architecture

diffray's unique multi-agent architecture consists of over 30 specialized agents, each focusing on different dimensions of code quality. This allows for a more precise and thorough code review process, minimizing irrelevant alerts and maximizing actionable insights.

Reduced False Positives

With an impressive 87% fewer false positives, diffray ensures that developers spend less time sifting through irrelevant feedback. This precision leads to more meaningful and effective code reviews, allowing teams to focus on real issues that matter.

Fast Review Times

The average time for pull request reviews is cut down from 45 minutes to just 12 minutes per week. This speed boosts overall productivity and allows developers to iterate faster, leading to quicker deployment cycles and improved team agility.

Seamless Integration

diffray integrates effortlessly with popular platforms such as GitHub, ensuring that teams can adopt this powerful tool without disrupting their existing workflows. This level of integration enhances user experience and encourages widespread adoption among development teams.

Use Cases

CloudBurn

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.

Frequently Asked Questions

CloudBurn FAQ

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.
