FasterAPI

PyPI package: faster-api-web — pip install faster-api-web
Documentation assumes Python 3.10+, with examples tuned for Python 3.13 (see Python 3.13 & compatibility for fallbacks on older versions).

FasterAPI is an ASGI web framework that keeps a FastAPI-like API while swapping heavy internals for faster building blocks: msgspec for models and JSON, a radix router for paths, and uvloop where it helps.

Use this site for installation, a CRUD tutorial, migration notes from FastAPI, benchmark methodology, and the API reference. Inspiration and credit for the FastAPI ecosystem are on the Acknowledgments page.

Install from PyPI

pip install faster-api-web

Package name on PyPI is faster-api-web; you import FasterAPI in Python.

When to choose it

• You want routing and request handling that stays fast as you add more routes.
• You are fine defining request/response bodies with msgspec.Struct instead of Pydantic BaseModel.
• You want to stay close to FastAPI patterns (get/post, Depends, HTTPException, OpenAPI docs).
