What might Azure cost for a low-traffic Next.js and Flask app?

First, check the actual usage and charges for your existing resources in Azure Cost Management. Then put the same services and expected usage into the Azure pricing calculator. The bill depends on the plans and regions you choose, and a credit balance can make current costs look different from the normal pay-as-you-go rate.

If the frontend can be served as static files, Azure Static Web Apps may be a low-cost fit, with the Flask API hosted separately. If Next.js needs server-side rendering or other server features, check that the chosen hosting option supports them rather than assuming it works like a static site.

For a small API, a consumption-based serverless option can keep costs low when requests are infrequent. Just remember that usage-based billing can vary, and unexpected traffic can raise the bill. Set a budget and billing alerts, and review the service limits before committing.

Another route is a small always-on VM. It gives you a more predictable base cost, but you also take on server maintenance and pay while it is idle. Compare that fixed monthly price with the managed or serverless options, including any database, storage, bandwidth, and monitoring charges your app needs.

There are suggestions that a static frontend paired with a consumption-based backend could cost very little, and that a managed container option might stay under roughly ten dollars a month. Treat those as rough possibilities, not guarantees. Region, minimum capacity, runtime requirements, and traffic all affect the total.
