The blood test for your AWS bill.

Generate a local AWS audit report in minutes.

pip install kulshan
aws sso login
kulshan report

No setup. No data uploads. No infrastructure changes.

Just your AWS account and your laptop.

What is Kulshan?

Kulshan reads your AWS account and generates a business-ready report covering:

• Cost anomalies and trends
• Waste and orphaned resources
• Tag compliance and cost attribution
• Commitment health (RI/SP coverage)
• Spend forecasting and acceleration
• Security posture
• DR readiness

Think of it as a baseline before deeper FinOps work, platform evaluations, or leadership reviews.

What You Get

An HTML report you can open in a browser and hand to your VP, CFO, or platform team. Also available as JSON, SARIF, and CSV.

The report scores your account 0-100 across each dimension, highlights the top actions by dollar impact, and provides an executive summary paragraph.

Install

pip install kulshan

Requires Python 3.9+. macOS, Linux, Windows.

AWS Credentials

Kulshan uses the same AWS credentials as the AWS CLI.

aws sso login
kulshan report
