myfy

Build Python applications with FastAPI's ergonomics and enterprise-grade architecture.

A modern Python framework combining type-safe dependency injection, modular architecture, and sensible defaults—all in a lightweight, async-first design.

Quick Start

Installation

# Install with uv (recommended)
uv pip install myfy-core myfy-web myfy-frontend myfy-cli

# Or with pip
pip install myfy-core myfy-web myfy-frontend myfy-cli

Hello World

# app.py
from myfy.core import Application
from myfy.web import route, WebModule
from myfy.frontend import FrontendModule

@route.get("/api/hello/{name}")
async def hello(name: str) -> dict:
    return {"message": f"Hello {name}!"}

app = Application(auto_discover=False)
app.add_module(WebModule())
app.add_module(FrontendModule())

Run it:

uv run myfy run
# API: http://127.0.0.1:8000/api/hello/World
# Frontend: http://127.0.0.1:8000
