Simple WSGI server using pyuv

Project description

uvwsgi is a Python WSGI server whhich uses libuv and http-parser libraries also used in Node.JS through their Python binding libraries:


There are abunch of great WSGI servers out there, so why create a new one? I’ve been playing with Flask and WSGI lately and I wanted to see the guts of it. As you can see the code is pretty short, I expect to make more changes and more features to it though.


uvwsgi should not be used in production. It’s still work in progress.

The project is not very actively maintained at the moment, if you’d like to help please drop me a line!


uvwsgi can be easily installed with pip:

pip install uvwsgi


Example usage:

from flask import Flask
from uvwsgi import run

app = Flask(__name__)

def index():
    return 'hello world!'

if __name__ == '__main__':
    run(app, ('', 8088))

The uvwsgi command line application can also be used to serve WSGI applications directly. Assuming the code above this lines is stored in a file called, it can be served as follows:

uvwsgi tst:app --port 8888

NOTE: You need to install the package first in order to have the uvwsgi command available.
