FastAPI Backend Development
A modern, high-performance web framework for building APIs with Python 3.8+ based on standard Python type hints and ASGI.
When to use it
When building high-throughput APIs, AI/ML inference backends, microservices requiring OpenAPI documentation, and asynchronous event-driven services.
Advantages
- Extremely high performance comparable to NodeJS and Go
- Automatic interactive OpenAPI / Swagger documentation
- Native async/await support for non-blocking I/O
- Strict Pydantic data validation and serialization
When NOT to use it
For simple static brochure sites or monolithic applications where a full-stack framework like Django with built-in admin is preferred without microservices.
Limitations
- Smaller ecosystem of built-in admin plugins than Django
- Requires careful management of async CPU-bound vs I/O-bound tasks with process pools
