How It Works
- Parses your Bicep/ARM/Terraform file to extract resource types and SKUs
- Queries the Azure Retail Prices API (public, no authentication required)
- Displays estimated monthly costs inline, in the status bar, and in the sidebar
- Caches prices for 30 minutes to minimize API calls
Requirements
- VS Code 1.85+
- No Azure subscription or authentication required — the Retail Prices API is public
Privacy
This extension only calls the Azure Retail Prices API which is a public, unauthenticated API. No code, file contents, or telemetry is sent anywhere.
