Flask is a lightweight Python web framework ideal for microservices, APIs, and small to medium applications. Gunicorn serves Flask in production as a WSGI application server, while Nginx handles SSL, static files, and load balancing. This guide deploys Flask on Ubuntu 26.04 LTS. Tested and valid on: Ubuntu 26.04 LTS Prerequisites Ubuntu 26.04 LTS with […]
In this guide, you will build a Python application using the Flask microframework on Ubuntu 20.04. The bulk of this article will be about how to set up the uWSGI application server and how to launch the application and configure Nginx to act as a front-end reverse proxy.

Learn how to use Flask-SQLAlchemy to manage databases in Flask. Create models, perform CRUD operations, and build scalable Python web apps.
Learn how to efficiently improve your Flask application performance to improve scalability and responsiveness, ensuring it runs efficiently even under heavy load.
In this tutorial we will deploy a Flask App Using Gunicorn to the cloud provider’s App Platform.
In web applications, you usually need a database, which is an organized collection of data. SQLite is a simple and fast open source SQL engine that can be used with Python to store and manipulate application data. SQLite works well with Python because the Python standard library provides the sqlite3 module, which you can use to interact with any SQLite database. In this tutorial, you’ll build a small web application that demonstrates how to use SQLite with Flask.
In this tutorial, you’ll modify an application built using Flask and SQLite by adding a Many-to-Many relationship to it. A many-to-many database relationship is a relationship between two tables where a record in each table can reference several records in the other table. For example, in a blog, a table for posts can have a many-to-many relationship with a table for storing authors.
Flask is a framework for building web applications using the Python language, and SQLite is a database engine that can be used with Python to store application data. In this tutorial, you will use Flask with SQLite to create a to-do application where users can create lists of to-do items. You will learn how to use SQLite with Flask and how one-to-many database relationships work.
