Nexios (ASGI Python framework)

Question

Nexios – A Modern Python Web Framework Built for Speed

The Story Behind Nexios

Nexios was born out of frustration — frustration with bulky frameworks, unnecessary boilerplate, and the over-complication of simple tasks. I wanted a framework that had:

• the simplicity of Express.js
• the power of FastAPI
• the flexibility of raw ASGI
• and none of the magic Django-style meta-classes.

So I built Nexios — a lightweight, async-first Python web framework designed to help developers ship fast, clean, and production-ready APIs with minimal setup.

⚙️ How Nexios Works

Nexios is built on ASGI and designed with speed and clarity in mind. You define routes using Python functions — no decorators, no hidden base classes, no magic. Just clean, readable code.

from nexios import NexiosApp

app = NexiosApp()

@app.route("/hello")
async def hello(request, response):
    return {"message": "Hello, Nexios!"}

Under the hood, Nexios handles routing, request parsing, async middleware, response formatting, and more — all in a modular and blazing-fast ASGI engine.

Great post! Appreciate the effort in making Nexios clear and straightforward. I love the async-first, zero-magic approach sounds like a refreshing alternative to heavier Python frameworks. Have you noticed any performance benchmarks comparing Nexios to FastAPI or Starlette yet? Would be interesting to see how it stacks up in real-world use cases!
