Gunicorn

Gunicorn (Green Unicorn) is a Python Web Server Gateway Interface (WSGI) HTTP server for UNIX systems. It is designed to serve Python web applications by handling HTTP requests and communicating with Python frameworks via the WSGI interface. It is widely used for deploying Python web apps in production environments due to its simplicity, performance, and compatibility with various frameworks.

Also known as: Green Unicorn, Gunicorn WSGI, Gunicorn Server, Gunicorn HTTP Server, Gunicorn Python

Why learn Gunicorn?

Developers should use Gunicorn when deploying Python web applications in production, especially for high-traffic sites or when running behind a reverse proxy like Nginx. It is ideal for frameworks like Django, Flask, and Pyramid, as it efficiently manages worker processes to handle concurrent requests. Use it to improve scalability and reliability compared to development servers like Flask's built-in server.
