FastAPI vs Visual Studio

Yes. FastAPI is free and open-source under the MIT License. It costs nothing to download, use, or deploy in production. An optional paid service, FastAPI Cloud, offers one-command deployment for additional convenience, but the core framework is free.

Standard subscriptions include access to more benefits, such as Azure dev/test pricing, monthly Azure individual credit, software and download access, services, training, and support. Monthly subscriptions offer flexibility but fewer benefits.

Yes. FastAPI's MIT License permits unrestricted commercial use, modification, and distribution. You can build and sell products powered by FastAPI without licensing fees or restrictions.

There aren't any discounts available to start-ups, however an unlimited number of users within an organization can use Visual Studio Community for specific scenarios like open source work.

No. FastAPI does not include a built-in database or ORM. You must add separate libraries like SQLAlchemy for database access. This gives flexibility to choose the database solution best suited to your project.

In non-enterprise organizations, up to five users can use it. Enterprise organizations (greater than 250 PCs or greater than $1M annual revenue) cannot use it beyond academic/open-source scenarios.

FastAPI supports Python 3.7 and later. Older Python versions are not compatible, so you must run at least Python 3.7 to use FastAPI.
