Overview
What FastAPI does
FastAPI is an open source Python API framework licensed under MIT, built on Starlette and Pydantic with automatic interactive documentation.
The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about FastAPI.
- Licensed under the MIT License per fastapi.tiangolo.com; as open source software it has no paid tier or vendor price to compare
- FastAPI depends entirely on Starlette for its web layer and Pydantic for validation, per its own documentation, so it is not a standalone framework and inherits both dependencies' constraints

Softwr does not host reviews and shows no star rating for FastAPI, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
