CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams hunting for exposed S3 buckets during reconnaissance will find S3BucketList useful for its passive discovery approach; the Chrome extension catches bucket references embedded in web traffic that traditional scanners miss entirely. With 124 GitHub stars and zero setup friction, it's practical for small AppSec or cloud security teams that need quick surface-level visibility without deploying infrastructure. Skip this if you need automated continuous monitoring or remediation workflows; S3BucketList is a lightweight reconnaissance aid, not a replacement for cloud posture management tools.
AWS security teams managing multiple accounts will find Smogcloud's value in its speed; a Go-based tool discovers internet-facing assets faster than clicking through the console, and the free pricing removes procurement friction for proof-of-concept work. Its 347 GitHub stars signal active maintenance and community trust, which matters for tools living in your IaC pipeline. Skip this if you need multi-cloud coverage or deep asset context beyond discovery; Smogcloud is deliberately AWS-only and lightweight on enrichment.
