A blazing-fast Python web framework powered by Rust 🚀

🚀 sufast – A Blazing Fast Python Web Framework Powered by Rust

sufast is a hybrid web framework that combines the developer-friendly simplicity of Python 🐍 with the raw execution speed of Rust 🦀.

Built for high-performance APIs, scalable microservices, and modern AI-era backends, sufast delivers the best of both worlds:

---

⚡ Why sufast?

• 🚀 52,000+ RPS performance with Rust core
• 🐍 FastAPI-style decorator syntax (@app.get, @app.post)
• 📦 Easy to use and install

---

pip install sufast

⚠️ Requires Python 3.8+ and a platform-compatible Rust binary bundled in the package.

🚀 Quickstart

from sufast import App

app = App()

@app.get("/")
def hello():
    return {"message": "Hello from sufast 👋"}

app.run()

Visit -> http://localhost:8080/ 🚀

📚 Advanced Example – API Server

from sufast import App

app = App()

# 🧪 Sample database
users = {
    "shohan": {"name": "shohan", "email": "[e-mail]"},
    "bob": {"name": "Bob", "email": "[e-mail]"},
    "alice": {"name": "Alice", "email": "[e-mail]"},
}

@app.get("/")
def home():
    return {"message": "Welcome to sufast API 🚀"}

@app.get("/shohan")
def app_info():
    return {"message": "Built by Shohan – Power of Rust & Python ⚙️🐍"}

@app.get("/users")
def get_users():
    return {"users": users}

@app.post("/users")
def show_user():
    # This is a mocked POST example
    return {
        "data": users["bob"]
    }

app.run()

🔬 Load Testing with k6

// test.js
import http from 'k6/http';
import { check, sleep } from 'k6';

export let options = {
  vus: 100,
  duration: '10s',
};

export default function () {
  let res = http.get('http://localhost:8080');

  check(res, {
    'status is 200': (r) => r.status === 200,
    'response has message': (r) => r.json().message !== undefined,
  });

  sleep(0.001);
}

Run the test:

k6 run test.js
