**Caveats (show these word for word)**
- Stacks are read from each product's public code (manifests and environment templates) on the date shown; a service listed there may be optional or used only by the hosted version. GitHub and App Store figures are as read on their checked_at date.

Confidence: medium.

Use estimate_cost or audit_stack with the priced vendor ids to see what a stack like this costs.
