Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
FastAPI
- No built-in ORM, requires separate database libraries
- Python-only, cannot build with other languages
- Async/await learning curve for developers new to async programming
- Production deployment requires separate ASGI server configuration

- The standalone desktop app is no longer available or supported
- The completion specs remain open source on GitHub, but the product that consumed them is gone

Which should you pick?
Questions people ask
- Is FastAPI or Fig better?
- Neither clearly leads. FastAPI starts at Free and Fig at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, FastAPI or Fig?
- FastAPI starts at Free and Fig at Free.
- Does FastAPI or Fig run on more platforms?
- Both run on Web, so platform support will not decide this one for you.
- Can I use FastAPI for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is FastAPI best used for?
- FastAPI is most often used for building production-ready rest apis with automatic validation, serving machine learning model predictions as rest services, building crisis management and orchestration platforms, enabling real-time apis with websocket connections. Of those, building production-ready rest apis with automatic validation and serving machine learning model predictions as rest services are not what Fig is typically brought in for.
Answered from the vendors’ own pages
FastAPI: Is FastAPI free to use?
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.
SourceFastAPI: Can I use FastAPI for commercial applications?
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.
SourceFastAPI: Does FastAPI include a database or ORM?
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.
SourceFastAPI: What Python versions does FastAPI support?
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.
