Azure Static Web Apps is free at the minute, and I've heard the pricing will be very reasonable once it comes out of preview (in the cents/pennies probably unless you're really popular!) https://azure.microsoft.com/en-gb/services/app-service/stati... Would recommend giving it a bash, or you could deploy it manually with Azure Blob Storage Websites and a simple deployment CI pipeline.
With free private repos and that kind of integration it's a pretty neat setup.
