CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams managing sprawling AWS environments need aws_public_ips to find what they've actually exposed across EC2, CloudFront, ELB, RDS, and other services in minutes, not weeks of manual inventory work. The tool's 642 GitHub stars reflect its adoption among practitioners who value speed and specificity over UI polish. Skip this if your organization already has a mature CSPM feeding real-time asset data into your EASM platform; aws_public_ips shines as a quick audit tool or gap-filler, not as a continuous monitoring layer.
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.
