FastAPI vs Smalltalk: The Verdict

⚡ Summary:

FastAPI: FastAPI is a modern, high-performance web framework for building APIs with Python 3.6+ based on standard Python type hints. It's very fast and easy to use, has automatic validation, OpenAPI docs, and more.

Smalltalk: Smalltalk is an object-oriented, dynamically typed, reflective programming language. It was designed for incremental code development and testing, featuring an integrated development environment, a file system, and a system command shell. It paved the way for many IDE features that are now common in other languages.

Both tools serve their respective audiences. Compare the features, pricing, and user ratings above to determine which best fits your needs.
