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 platform teams managing sprawling AWS test environments will get immediate value from cloud-nuke because it actually deletes resources at scale instead of just flagging them, cutting cloud waste before it becomes a budget crisis. With 3,028 GitHub stars and active use across teams running dozens of test accounts, the tool proves its reliability for bulk resource cleanup that manual deletion can't match. Skip this if you need fine-grained RBAC controls or want to prevent deletions across certain resources; cloud-nuke is a bulldozer, not a scalpel, and requires disciplined account segmentation to avoid accidents.
