Flask Vs Django: The Ultimate Comparison Guide (2021)


Many python based web frameworks allow developers to build stable applications quickly. From simple to complicated websites, these frameworks can do all. Out of the many popular choices, Flask vs Django are most talked about and mostly because both are very comparable in some ways and distinct in many other ways. It leads to a similarity between both and why each of these web development frameworks has its features. There are a majority of factors that we should look at before choosing one for our applications.

On the one hand, Django is a full-stack web development Framework, whereas Flask is a lightweight, extensible framework. If we want to dig more into coding and learn some core concepts, Flask helps us understand how each component from the back and works for getting a simple web application up and running. Django follows different design patterns and hands. We can learn a lot of exciting concepts. Moreover, with both frameworks, there is a whole other community support and documentation. If we run into any problem, the chances are that the issue has already been discussed and sorted out, which will make our work easier.

Django is heavyweight, whereas, in Flask, we are required to build everything on our own. The Django has been around since 2005, whereas the Flask web framework kept its foot in 2010 about five years later. Nevertheless, both are the top framework of python in the world today. They are going popularity is evident while considering the number of questions people ask about these frameworks in various tech forums.

Django

Django is a web application framework that takes care of most of the standard functionalities for building a secure and maintainable website. As a developer, all we require is making our business logic. Django is free, and an open-source framework has beautiful and helpful community support with loads of documentation. The named Django orderly came into life in July 2005 and using it, we can get most of the things out of the box in one single product. Therefore there are no alliance issues as well.

Features of Django

Some features of Django are:

  1. It is a versatile framework and could be used for any website with content in formats like HTML, XML, JSON, and more. It works in tandem with any client-side framework.
  2. It is a secure framework and can automatically manage the standard safety features like user account management, transaction management, cross-site request forgery, clickjacking, and more.
  3. It is scalable and maintainable as design patterns and principles for using and maintaining the code are followed. The main focus of don’t repeat yourself is making sure that there are no duplications. Asda Django is a component-based framework independent of the other, making the application scalable at any level.
  4. It is portable as it is written in python, the most popular programming language that can run anywhere.

Flask

Flask is a lightweight Framework, usually categorized as a micro Framework. Flask comes with some standard functionalities and allows developers to add many libraries and plugins as an extension. If we have an uncomplicated and innovative use case to be added into an existing application, the Flask web framework could be one of our choices as it offers flexibility. 

It comes with a small set of easy to learn API and the documentation is also excellent. If we are new to python, we could start our web development journey with flowers to get the backend and frontend feel and learn some of the core concepts.

Flask Advantages

Some Flask advantages are:

  1. Provides the full developer control of settlement for building the application during the implementation stage.
  2. Comes with a built-in developer server and a fast debugger.
  3. Consistent and neat API
  4. Easy and flexible configuration
  5. Restful and http request handling
  6. Integrated unit testing support

Which is better Flask or Django?

We may have got the hang of it by now; while Django is a full-fledged framework with a lot of functionalities already performed for us, Flask leaves everything under our control. These are not the only difference between Flask and Django as several differences will help us understand which one we should pick for our web application. Below are the difference between Flask and Django:

DjangoFlask
Full-stack web framework that implements the batteries-included approach.Lightweight framework and minimalist characteristics.
The most common features are now available to users, making development easier.The center of the program can indeed be discovered and managed by developers.
Django comes with a flexible ready-to-use administrative system.Flask has no such role to perform in certain duties of management.
The template engine is integrated which saves a great deal of production time.Flask’s Jinja2 template motor is based on the Django template motor.
It makes it easier to build and manage a single project in many small applications.However, several templates and views may be applied to a single application for each project.
The Django-admin tool is an advanced bootstrapping tool that allows development developers to create web applications without any external feedback.Admin features are not as influential as in Django.
The integrated ORM helps developers to use any databases, without having to write lengthy queries, and to perform routine DB activities.Developers must use Python’s ORM systems and SQLAlchemy as their SQL toolkit with Flask of different databases. For basic activities, SQL queries must be written.
Django is a ready-made platform for development.Although some people are saying so, Flask has a single thread which could be insufficient for a heavyweight.
The fact that Django offers many out-of-box features and reduces time to create complex applications is considered more common.Flask is a good start when we start creating the site. Many websites are constructed on the flask and get a lot of traffic, but not as much as Django websites.
For projects in which specifications change dynamically, Django is not suitable.A basic program with Flask will later be modified to add additional features and complicate it. It offers versatility for the fast extension of the program.

Conclusion

There is a common issue for many developers – which framework is better? We might have got a fair idea by now of how each framework operates and what are the best ways for using each of them. Nevertheless, several Flask-made high-traffic websites are nice and similar to those built on Django. While Flask vs Django shares quite a few simple principles, Django is nuanced, detailed, and demands a profound learning curve. If we want to get the ‘feel’ of a web frame, begin with Flask, then move on to Django for more advanced applications.
