  • Allows you to only process one request at a time.

Flask Vs Django Popularity

Flask vs Django popularity

Flask and Django are both popular web frameworks for Python. Flask is a full-featured web framework that provides everything needed to build complex web applications. It is a lightweight framework that is more focused on simplicity and flexibility.

There are several reasons why Flask has gained popularity among developers:

Lightweight: Flask is a lightweight framework, which means it doesn’t come with too many pre-built features, but instead provides the flexibility to add the features you need. This makes it easy to build and deploy applications quickly.

Easy to Learn: Flask is relatively easy to learn compared to other web frameworks, making it an ideal choice for beginners who are just starting to learn web development.

Flexibility: Flask is highly customizable and allows developers to create web applications of any size and complexity. It is also compatible with a variety of web development tools and libraries, giving developers the flexibility to choose the tools they prefer.

Active Community: Flask has a large and active community of developers who are constantly contributing to its development and improving its features. This means that there are always new plugins, extensions, and resources being developed that can be used to enhance Flask-based web applications.

Scalability: Flask can be used to build small-scale web applications as well as large-scale ones. Its scalability makes it suitable for a wide range of web development projects.

What Are The Differences Between Flask Vs Django?

Here are some differences between flask vs Django: 


The batteries-included technique is used in this full-stack web framework.
low-weight Framework with minimalistic features.

The most common features that speed up development are already available to developers.

Developers can investigate the application’s core while maintaining control.
Django comes with a customizable admin framework that is ready to use.Flask lacks such a tool for handling administrative tasks.
It has a built-in template engine that saves a lot of time during development. Flask’s template engine Jinja2 is based on Django’s template engine.
It allows users to break down a single project into numerous smaller apps, making them easier to develop and maintain.Each project can be a single application with numerous models and views, while the single application can have many models and views.
The Django-admin tool is a built-in bootstrapping tool that allows developers to create web apps without using any additional resources.The administration features aren’t as prevalent as they are in Django.
Developers may use any database and execute standard DB functions without having to write extensive queries thanks to the built-in ORM technology.Developers working with Flask must use ORM systems for Python and SQLAlchemy as the SQL tools to work with various databases. For common jobs, SQL queries must be written.
It is a production-ready framework.Flask is single-threaded and may not run adequately under severe demand, despite what some people assert.
Django is more popular since it comes with a lot of functionality out of box features and speeds up the development of complex applications.If you’re new to web programming, Flask is a good place to start. Many websites are built with Flask and receive a lot of traffic, but not as much as those built with Django.
The Django framework ensures that developers follow best practices as everything has a template.Flask is more open-ended, and developers might or might not use the best practices.
Django requires more than twice as many lines of code as Flask for the same functionality.For a simple task, a Flask application takes far fewer lines of code.

Flask Vs Django Usage Comparison 

One of the most common standard web technologies is Node.js, React.js, jQuery, express, etc. It is used by Professional Developers and those people who want to learn to code. Angular is used more by Professional Developers than those learning to code (23% vs 10%), same with ASP.NET Core (21% vs 10%) and ASP.NET (16% vs 10%), Django (16% vs 10%), and Flask (15% vs 10%).
