Antiope AWS Inventory & Compliance Framework

The framework inventories resources via cross-account assume roles into a centralized S3 bucket, giving you a single source of truth for compliance audits and drift detection at zero cost. Skip this if your organization demands a commercial UI, managed alerting, or real-time remediation workflows; Antiope is a data collection engine that requires you to build analysis and response on top.

The 461 GitHub stars and zero setup friction mean you can scan your entire S3 estate for misconfigurations, overpermissioned ACLs, and unencrypted data in minutes, not weeks. Skip this if you need continuous runtime monitoring or policy enforcement across your broader cloud infrastructure; s3tk is a scanner, not a guard rail, and works best as part of a larger CSPM rather than a replacement for one.
