What It Does

One CLI that inventories 27 AWS services and 80+ resource types, then lets you track drift, enforce compliance, generate Terraform and CDK, scan for security issues, manage Lambda code, query resources with SQL, and clean up what shouldn't be there. 60+ commands. Zero agents running in your account.

Note: "Snapshot" in this tool means an inventory snapshot (a catalog of what exists), not an AWS EBS or RDS snapshot. No AWS snapshots are created.

Problem	Solution
"What's actually running in our account?"	Snapshot 80+ resource types across all regions in one command
"What changed since last week?"	Field-level configuration drift detection between snapshots
"Are we following security best practices?"	12+ CIS-aligned checks with severity filtering
"Someone spun up a bunch of test resources"	Delete everything created after a baseline snapshot
"I need Terraform for existing resources"	Generate Terraform or CDK from live inventory with guardrails
"What's in that Lambda function?"	Extract, view, and diff deployment packages across snapshots
"Are our guardrails being followed?"	YAML-based compliance policies with BLOCK/WARN/AUTO-FIX
"I need a resource explorer for the team"	Launch a web UI with awsinv serve

---

Quick Start

pip install aws-inventory-manager

Or with pipx: pipx install aws-inventory-manager

# 1. Organize snapshots into a collection
awsinv collection create prod-baseline --description "Production account"

# 2. Capture current state into the collection
awsinv snapshot create my-baseline --collection prod-baseline --region us-east-1

# 3. View what was captured
awsinv snapshot report

# 4. Track changes
awsinv delta --snapshot my-baseline --show-diff

# 5. Find security issues
awsinv security scan --severity HIGH

# 6. Clean up (always preview first!)
awsinv cleanup preview my-baseline
awsinv cleanup execute my-baseline --yes

See the full Getting Started tutorial for a complete walkthrough.
