CST VerdictBased on our analysis of available product data, here is our conclusion:
Teams building an initial asset inventory across sprawling AWS accounts should start with AWS Resource Discovery because it discovers what you actually have before you can defend it, and the free price tag means zero friction to run it today across dev and prod environments. The tool catalogs resources in JSON format via botocore, giving you the raw material to feed into downstream CSPM or CIEM tools rather than replacing them. Skip this if you need continuous monitoring or remediation workflows; it's a one-time discovery pull, not a persistent control plane.
DevOps and cloud security teams managing sprawling AWS multi-region deployments will find Resource Counter valuable for the foundational visibility problem it solves: getting an accurate inventory of what you actually have before you can secure it. The command line approach keeps overhead minimal and makes integration into existing automation workflows straightforward, avoiding the bloat of GUI-heavy tools. Skip this if you need real-time monitoring or compliance reporting; Resource Counter is inventory-first, not a replacement for continuous asset management platforms.
