## What it is
A multi-threaded CLI tool written in Go that scans for misconfigured (open) S3 buckets across AWS and other S3-compatible providers like GCP, DigitalOcean, and Scaleway. It can enumerate bucket permissions and objects, save results to Postgres, and integrate with RabbitMQ for scanning at scale.

## Use cases
- find open s3 buckets
- scan for misconfigured aws buckets
- check bucket permissions for a list of bucket names
- bug bounty recon for exposed cloud storage
- audit s3-compatible storage across cloud providers
- enumerate objects in public buckets

## When to choose
- you need fast, multi-threaded bucket misconfiguration scanning
- you use multiple S3-compatible providers or a custom endpoint
- you want automated scanning at scale via RabbitMQ or results stored in Postgres

## When to avoid
- you need general cloud security posture management beyond object storage
- you want a GUI-based cloud audit tool
- you rely on the legacy Python version, which is no longer maintained
