Your first cost check starts here.

Scan Terraform and CloudFormation for costly patterns before deployment. Run discovery against live AWS to find waste already in your account. Use the CLI locally or in your CI pipeline.

Cost analysis / Platform preview

AWS Cost Tree

See where your AWS spend went, and what changed.

Map the last 30 days of spend in a connected account by service and usage type, or by Region, and compare it with the 30 days before. Color tiles by change to spot what grew, and see the fastest-growing usage types and known waste patterns such as NAT data processing and gp2 volumes. The cost data is stored in your own results bucket.

IaC Cost Estimator

See the cost of a change before it merges.

Bring AWS cost reports into GitHub pull requests for Terraform, CloudFormation, and AWS CDK. Review the cost change alongside the code, with assumptions and missing inputs made explicit.

Cost optimization / Platform preview

Unused resources

Find what is costing money without doing work.

Idle NAT gateways, unattached EBS volumes, RDS instances with no connections, load balancers without targets. 31 checks find what you can remove, stop, or release, and each finding shows the evidence and the monthly cost behind it.

How Unused Resources works
Findings sorted by what they cost you each month. Platform preview with sample data.

Cost optimization / Platform preview

Resource efficiency

Make the resources you keep work harder.

Rightsize low-utilization instances, move to Graviton and gp3, schedule Redshift pauses, and catch RDS engines that are running up extended support charges. 38 checks compare what you run with what you could run, with savings where AWS or CloudBurn has the evidence.

How Resource Efficiency works
Current and recommended configurations, side by side. Platform preview with sample data.

Cost optimization / Platform preview

Commitment savings

Stop paying On-Demand rates for steady workloads.

Find RDS, Redshift, and ElastiCache capacity that has run On-Demand for months without reserved coverage, Savings Plans purchases AWS recommends for your usage, and EC2 reservations about to expire. Weigh the savings before you commit.

How Commitment Savings works
Coverage gaps and renewals before they cost you. Platform preview with sample data.

Cost optimization / Platform preview

Cost Governance

Check the controls around your AWS spending.

Catch AWS Budgets that are over their limit or forecast to break it, accounts without Budgets or Cost Anomaly Detection, and resources without the tags you need to allocate spend.

Cost optimization / Platform preview

Check the evidence before you change anything.

Open any finding to see the resource, the check that flagged it, the metrics behind it, and what it costs each month. Remediation commands are examples for you to review and run yourself. CloudBurn never runs them in your account.

From your terminal to every account

Already running the CLI? Let the Platform run it across your accounts.

Connect your AWS accounts and GitHub organization once. CloudBurn Platform scans the accounts you connect with the same open-source rules and keeps the scan history, so a finding in the dashboard carries the rule name you already know from the CLI. The CloudBurn GitHub App adds cost reports to your pull requests.

CloudBurn Platform / How the connection works

Your scan results stay in your AWS account.

CloudBurn Platform connects through an IAM role you deploy in your own AWS account, and scan results stay in an S3 bucket you own. CloudBurn reads the results from your bucket to draw the dashboard instead of keeping its own copy.

Reads your resources with ReadOnlyAccess
The role uses the AWS managed ReadOnlyAccess policy. It can read your resources, their configuration, and the data they hold.
Writes only to your results bucket
Its one write permission is scoped to the S3 bucket that stores your scan results. It cannot change your other resources.
No long-lived credentials
CloudBurn assumes the role for short-lived sessions to run a scan. It never stores access keys for your account.
Remove the role to cut access
Delete the stack or run terraform destroy, and CloudBurn can no longer reach the account.

Before you
get started

What access does CloudBurn need to my AWS account?

The open-source CLI checks Terraform and CloudFormation locally without AWS credentials, and runs live discovery with your own credentials. CloudBurn Platform connects through an IAM role you deploy in your own account from a CloudFormation or Terraform template. The role uses the AWS managed ReadOnlyAccess policy, which can read your resources and the data they hold, plus write access to one S3 bucket you own, where scan results are stored. CloudBurn holds no long-lived credentials.

See what you deploy in the connection docs

What can I use today?

CloudBurn Open Source is available now. Install the CLI to check Terraform and CloudFormation for costly patterns and run discovery against live AWS resources. The free, individual AWS calculators are also available on this site.

What does the Platform add to the open-source CLI?

CloudBurn Platform runs the CLI's work for your team. It adds shared workspaces, unused-resource scans of the AWS accounts you connect with scan history, the AWS Simple Pricing Calculator, and pull-request cost reports through the CloudBurn GitHub App. The scans use the same open-source rules, so a finding carries the same rule name you get from the CLI.

What happens to my data if CloudBurn shuts down?

Your scan results are already in the S3 bucket in your account. The rules the Platform runs are the open-source rules, released under the Apache-2.0 license, and you can keep running them with the CLI. The IAM role and the bucket live in your account too: delete the role with the stack or with terraform destroy whenever you want.

When will CloudBurn Platform launch?

CloudBurn Platform is expected to open in early 2027. Waitlist members get 30% off when it launches and keep it for as long as they keep their plan. Joining does not start a trial or a paid plan. Two emails a month at most. Unsubscribe anytime.
