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.


Key Features

  • Async-first: Built on ASGI for native async performance.
  • Minimal boilerplate: Get up and running in 5 lines of code.
  • Custom Auth Backends: JWT, API keys, token rotation, blacklisting — all pluggable.
  • ORM-Agnostic: Works with Tortoise, Prisma, SQLAlchemy, or no ORM at all.
  • Zero Magic: No hidden behavior or metaclass gymnastics.
  • Fast Startup: Instant dev server, instant reload.
  • Auto Docs: Generate OpenAPI docs without extra setup.
  • Extensible Core: Built to be hacked and extended.

How to Get Involved

Nexios is open-source and community-friendly. You can:

  • Star the repo on GitHub
  • Report bugs or request features
  • Contribute modules or plugins
  • Join discussions in the community

Ready to Try It?

Install it now:

pip install nexios

Create a new project:

nexios new  <project_name>

Then start building APIs your way.


Built by developers, for developers. Nexios is what Python web development should feel like.

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!
