# Gunicorn |  | The **Gunicorn** "Green Unicorn" is a Python Web Server Gateway Interface (WSGI) HTTP server. It is a pre-fork worker model, ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with a number of web frameworks, simply implemented, light on server resources and fairly fast. It is often paired with Nginx, as the two have complementary features. | | ------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | | wikipedia:: [Gunicorn](https://en.wikipedia.org/wiki/Gunicorn) | | | url:: [Gunicorn](http://www.gunicorn.org) | - Pronounced 'GEE-unicorn'
