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.
SourceNx Cloud: What is included in the free Hobby plan?
The Hobby plan includes 50,000 monthly credits, support for 5 contributors, 10 concurrent CI connections, and basic analytics at no cost with no credit card required.
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.
SourceNx Cloud: How are overages charged on the Team plan?
The Team plan starts at $29/month with included credits. Additional credits cost $5.50 per 10,000 credits, extra contributors cost $19 each, and additional CI connections cost $2.25 each.
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.
