Gunicorn, or Green Unicorn, is a UNIX-compatible WSGI HTTP server that is commonly used to run Python applications.
Developed in 2010 by Benoit Chesneau, this open source project is similar to uWSGI, mod_wsgi, and CherryPy.
Gunicorn is often implemented with a reverse proxy server like NGINX, which typically handles requests for static resources and then passes on the requests to Gunicorn.
Gunicorn processes the dynamic portion of the request and returns a response to NGINX, which sends the response back to the client.

Gunicorn can be used to serve Python applications and is compatible with frameworks like Django, Flask and Bottle.
It’s easy to configure, lightweight, and only needs 4–12 worker processes to handle hundreds or thousands of requests per second.
