Python Waitress: A Comprehensive Guide to the WSGI Server

Python Waitress is a powerful WSGI server that is widely used in the Python ecosystem. In this guide, we will explore the features, installation process, and usage of Waitress. Whether you are a beginner or an experienced Python developer, this guide will provide you with all the information you need to get started with Waitress.

What is Waitress?

Waitress is a WSGI (Web Server Gateway Interface) server for Python 3. It allows you to serve your Python web applications with ease. Waitress is designed to be simple, reliable, and efficient. It can handle multiple concurrent requests and provides good performance.

Installation

Installing Waitress is straightforward. You can install it using pip, the Python package manager. Open your terminal or command prompt and run the following command:

pip install waitress

Once the installation is complete, you can verify it by running the following command:

waitress --version

This will display the version of Waitress installed on your system.

Running a Python Web Application with Waitress

Using Waitress to serve a Python web application is simple. Let's assume you have a Python web application called 'myapp.py'. To run this application with Waitress, use the following command:

waitress-serve --call myapp:app

This command will start the Waitress server and serve your application on the default port 8080. You can access your application by opening your web browser and navigating to 'http://localhost:8080'.

Binding Externally

By default, Waitress binds only to the local loopback address (127.0.0.1). If you want to make your application accessible from other machines on the network, you need to bind Waitress to the external IP address of your machine. Use the following command to achieve this:

waitress-serve --listen=*:8080 --call myapp:app

This will bind Waitress to all network interfaces on port 8080.
