Review FastAPI?

Reviewers describe FastAPI as a strong fit for API work because it feels fast, easy to use, and efficient in day-to-day development. The clearest repeated praise is performance, with one user calling its speed unmatched and highlighting the built-in interactive API docs as a major time-saver. Founder feedback is mostly sparse, but one maker from Legitt E-Signature also points to high performance and asynchronous capabilities for API development. There is little detailed criticism in the available reviews.

FastAPI's async-first architecture with Pydantic validation and automatic OpenAPI generation helped a lot without implementing things manually. We're handling thousands of concurrent requests with really good response times. The dependency injection makes our service layer clean, while the built-in middleware stack handles CORS, authentication, and request context out of the box. Also, the automatic type checking and validation have caught bugs before they hit production.
