Cost

Approximate monthly cost in one region with the minimal profile and demo traffic.

Resource Tier Monthly
Container Apps (web, summarizer) Consumption, scale to zero $0 within the monthly free grant (180,000 vCPU-seconds, 360,000 GiB-seconds, 2 million requests)
Azure SQL Database Free offer (100,000 vCore-seconds and 32 GB) $0. The database pauses after an hour idle or when the allowance is used
Service Bus Basic Pennies ($0.05 per million operations)
Storage account Standard LRS Under $0.50
Key Vault Standard About $0 ($0.03 per 10,000 operations)
Log Analytics Pay-as-you-go $0 within the first 5 GB
Container Registry Basic About $5 (the one fixed cost)
Deployment scripts (database access setup) Temporary, per deploy Pennies
Claude Haiku Per token Cents
Mailgun Existing plan $0 at demo volume
Docs site Azure Static Web Apps, Free $0

Total: about $5 to $6 a month. aspire destroy removes everything and the Azure cost returns to $0.

The scalable profile keeps one web replica running at all times, which uses part of the Container Apps free grant continuously.
