Flask vs Django in 2021: Which Framework to Choose?


Django and Flask are by far the most common Python web frameworks, according to the 2020 JetBrains Python Developers Survey. Do you want to know which platform, Flask vs Django, is better for web development for you? 

Flask vs Django is the most talked-about of the many common options available out there. There is a good reason for that, they are similar in some ways and different in others! This leads to a comparison of the two. While each of these web development frameworks has its own set of features, there are several things to consider before selecting one for your applications.

In this blog, I will show you the features of both Flask vs Django and do a comparison among them.

What is Django?

Django is a web application framework that handles many of the common functionalities needed to create stable and maintainable websites. It is a free and open-source web framework written in python. Django has a thriving community and also holds extensive documentation.

With Django, you get most of the features as a single product right out of the box. As a result, there are no problems with integration.

Features of Django

The following are some of Django’s features:

  • It’s a flexible platform that can be used to create any website (social network, news site, content management system, and so on) with content in HTML, XML, JSON, and other formats.
  • It takes care of things like user identity management, transaction management, cross-site request forgery, clickjacking, and other security concerns.
  • Since Django is a component-based architecture, each layer is self-contained, allowing the application to scale at any stage.
  • Django is a lightweight programming language. It’s written in Python, which is currently the most common cross-platform programming language.

Advantages of Django

  • Django is simple to install and use.
  • It offers a user-friendly interface for a variety of administrative tasks.
  • It has a built-in internationalisation scheme that allows it to include multilingual websites.
  • End-to-end application testing is possible with Django.
  • Allows you to create an HTML output to record your API.
  • Several authentication protocols are well supported by the REST Framework.
  • It can be used to restrict the number of API requests from a single user.
  • Allows you to identify patterns for your application’s URLs.
  • It comes with a built-in authentication system.

Let’s move on to the features of Flask.

What is Flask?

Flask is a lightweight framework that is often referred to as a micro framework. Flask like Django is also written in Python. Flask comes with some basic features and allows developers to add as many libraries or plugins as they want to an extension. 

Flask should be your first option if you have a quick, creative case that needs to be applied to an existing application. Begin your web development with Flask if you’re new to Python, so you can get a feel for both the backend and frontend, as well as learn the core concepts.

Features of Flask

The following are some of Flask’s features:

  • Gives you (the developer) complete control over how the application is built during the development (implementation) period.
  • It has a built-in development server as well as a fast debugger.
  • Logical and well-organised API (Application Programming Interface)
  • Configurations are simple and adaptable.
  • Handling RESTful and HTTP requests.
  • Support for integrated unit testing.
  • Werkzeug and Jinja2 are Flask’s two key dependencies, providing solid WSGI support and templates, respectively.

Advantages of Flask

  • Improved connectivity with cutting-edge technology
  • For basic situations, it’s easier to use.
  • For simple applications, there are a lot of scalabilities.
  • It’s simple to create a fast prototype.
  • Routing URLs is easy.
  • It is easy to integrate a database.
  • A platform that is both simple and efficient.

Flask vs Django: Comparison

The Django-admin tool is a built-in bootstrapping tool that allows developers to create web applications without requiring any external resources. The administration features aren’t as prominent as they are in Django.
Developers can use any database and perform typical DB tasks without having to write long queries thanks to the built-in ORM framework.Developers working with Flask must use ORM systems for Python and SQLAlchemy as the SQL toolkit to work with various databases. For common tasks, SQL queries must be written.
Django is a production-ready framework that can be used in development.Flask is single-threaded and does not work well under heavy load, despite what some people say. 
Django is more common because it comes with a lot of out of the box features and speeds up the development of complex applications.If you’re new to web development, Flask is a good place to start. Many websites are designed with Flask and receive a lot of traffic, but not as much as those built with Django.
Django is not appropriate for projects with changing specifications.Developers are free to use any plugins or libraries they choose, and they can create functionalities in a variety of ways.A basic application can be modified later with Flask to add more features and make it more complex. It gives you the freedom to easily extend your application.
Django is best designed for larger projects with a lot of features. The features could be an overdose for more straightforward ventures.Flask is a straightforward platform that lets developers determine how their applications should look.
Because everything in the Django system has a blueprint, it ensures that developers follow best practices.Flask is more open-ended because developers can choose to follow best practices or not.
Django needs more than twice as many lines of code as Flask for the same features.For a simple job, a Flask programme needs far fewer lines of code.
Django offers you a Monolithic working style.A diversified working style is offered by Flask.

Frequently Asked Questions

Is flask easier than Django?

If you’re new to web development but not to Python, you’ll find it much simpler to get started with Flask since it feels quite similar to working with vanilla Python to establish request handlers, views, and other stuff. Django has a significant amount of overhead.

Which is better: Flask or Django?

Django is considered more popular because it comes with a lot of out of the box features and speeds up the development of complex applications. If you’re new to web development, Flask is a good place to start. Many websites are designed with Flask and receive a lot of traffic, but not as much as those built with Django.

Which is better Django or flask for beginners?

Before moving on to larger frameworks like Django, beginners can try Microframeworks like Flask. After learning the small pieces of Web Applications, you can probably use Django.

Are flasks outdated?

Flask has been updated 27 times since its inception in 2010. It is also the fastest-growing Python platform. Many Flask extensions, on the other hand, are no longer supported: the documentation is out of date, and the extensions are no longer being made.

Key Takeaways

Django is a free and open-source web platform written in Python. It follows the model-template-views architectural pattern. Flask on the other hand is a micro-framework that provides simple web app functionality without the need for external libraries.

So which is better?

If you want granular power, you should use Flask, while a Django developer relies on a large community to build unique websites. Django combined with the REST Framework allows you to create powerful APIs, while Flask takes more effort and hence has a higher risk of error. The best way to determine which framework best suits your project style is to create a few simple CRUD apps for both frameworks.
