Definition
AWS Resource Explorer is a free, multi-region search service that indexes the resources in your AWS account (or AWS Organization) and lets you query them across regions and services from a single endpoint. Released GA in 2022 and substantially expanded through 2024–2026 to support most AWS services.
What it provides
- Multi-region search — Find resources in any region from one query
- Multi-account search — Aggregated index across an AWS Organization
- Views — Saved queries with IAM-based access controls for self-service search
- Tag and attribute filtering — Query by tag, type, region, ARN substring
- Console + API + CLI — Same query layer everywhere
When to use Resource Explorer
- “Where did I leave that EBS volume?” type questions
- Decommissioning a region or service — Find every resource that needs cleanup
- Cost-allocation tag enforcement — Find resources missing required tags
- Auditing across an Organization — Quick first pass before AWS Config queries
Resource Explorer vs alternatives
| Tool | Best for |
|---|---|
| Resource Explorer | Free, fast multi-region search and one-time queries |
| AWS Config | Continuous configuration history, compliance rules, drift detection |
| AWS Resource Groups | Logical grouping by tag for batch operations |
| AWS Tag Editor | Manual tag updates across resources |
Common mistakes
Mistake 1: Confusing Resource Explorer with AWS Config. Resource Explorer is a search index, not a compliance / history engine. Use Config for evidence and rules.
Mistake 2: Skipping aggregator setup. Without the Organization-level aggregator index, you cannot query across accounts.
Mistake 3: Not granting IAM permissions correctly. Resource Explorer needs both resource-explorer-2:Search AND the underlying service read permissions for the resources you want to find.
