Use Cases

Vendor Inventory

Generate a complete list of third-party services:

vg scan --format json | jq '.serviceDependencies'

Cloud Migration Planning

Identify AWS-specific services before migrating to Azure:

vg scan --format json | jq '.serviceDependencies.cloud'

Cost Analysis

Map services to billing by correlating detected SDKs with vendor invoices.
