FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.
The Key features are:
<ul>
<li>
Fast: Very high performance, on par with NodeJS and Go (thanks to Starlette and Pydantic). One of the fastest Python frameworks available.
</li>
<li>
Fast to code: Increase the speed to develop features by about 200% to 300%.
</li>
<li>
Fewer bugs: Reduce about 40% of human (developer) induced errors.
</li>
<li>
Intuitive: Great editor support. Completion everywhere. Less time debugging.
</li>
<li>
Easy: Designed to be easy to use and learn. Less time reading docs.
</li>
<li>
Short: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs.
</li>
<li>
Robust: Get production-ready code. With automatic interactive documentation.
</li>
<li>
Standards-based: Based on (and fully compatible with) the open standards for APIs: OpenAPI and JSON Schema.
</li>
</ul>
