Gunicorn
The Gunicorn "Green Unicorn" is a Python Web [Server Gateway Interface] 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.
