Django vs Flask: What’s the Difference Between Django & Flask?

To understand the clear difference between Django and Flask, we need to be clear on several concepts. 

Business operations now cannot function without web development. The internet and the digital world are currently being investigated by every industry for potential growth. A key component of that digital growth is creating a website tailored to the users and the target audience.

Subsequently, all of this has enhanced the field of web development. With the demand for high-end products, web development has gotten more sophisticated and complex. Frameworks are needed by developers in order to produce high-end products with dynamic, fully working websites.

Now let us see what this framework is and how it is connected to Django and Flask. 

Two of the most well-liked web frameworks for Python are Django and Flask. Due to the requirement for greater flexibility that would allow designers to choose how they want to implement things, Flask emerged as a rival to Django. Django, on the other hand, does not allows such extensive modification of its modules. Working with Flask allows an experienced Python developer to complete projects in extremely short time periods because it is so simple and direct.

Here are a few use cases for Flask and Django: While Django is fantastic for building complex destinations with energetic content and adaptability in mind, large projects that require out-of-the-box solutions can be sent really quickly, and Flask is exceptional for building basic locales with inactive content, like blogs. It gives all the functionality you would like and permits customization to a tremendous extent. Flask is perfect for developing simple web apps. Django’s preset modules allow for rapid app development and layout, which enables transmitting more complex web apps more quickly. 

What is a Framework?

The framework is a collection of modules that helps developers write the code for a web application. It is a fully-developed package that makes the web development process easier, faster, scalable, and reliable. 

Frameworks created in the Python programming language include Django and Flask. According to the Developers Survey 2018, these Python-based Frameworks are among the Most Popular Frameworks for Web Development.

To understand which frameworks are best, we need to understand in detail what Flask and Django are?


Python has a web development framework called Django. A standardized approach for quick and efficient website construction is provided by this framework. You may create and maintain high-quality web apps with its assistance. It enables you to speed up and save time on the development process.

It is a high-level web framework that allows performing rapid development. The primary goal of this web framework is to create complex database-driven websites.

Features of Django

Here are important features of Django:

  • Offers Model – View – Controller (MVC) Architecture.
  • Predefined libraries for imaging, graphics, scientific calculations, etc.
  • Supports multiple databases.
  • Cross-platform operating system.
  • Site optimization across specialized servers
  • Support for front-end tools like Ajax, jQuery, Pyjamas, etc.
  • Supports multi-Language and multi-characters.

Advantages of Django

Here, are the pros/benefits of the Django framework:

  • Django is easy to set up and run
  • It provides an easy-to-use interface for various administrative activities.
  • It offers multilingual websites by using its built-in internationalization system
  • Django allows end-to-end application testing
  • Allows you to document your API with an HTML output
  • REST Framework has rich support for several authentication protocols
  • It is used for rate-limiting API requests from a single user.
  • Helps you to define patterns for the URLs in your application
  • Offers a built-in authentication system
  • Cache framework comes with multiple cache mechanisms.
  • High-level framework for rapid web development
  • A complete stack of tools
  • Data modeled with Python classes

Disadvantage of Django

Here, are the cons/drawbacks of the Django framework

  • It is a monolithic platform.
  • High dependence on Django ORM. Broad Knowledge required.
  • Fewer Design decisions and Components.
  • Compatibility with the latest technologies
  • A higher entry point for simple solutions
  • The larger size of the code
  • Too bloated for small projects
  • Underpowered templating and ORM
  • Templates failed silently
  • Auto reload restarts the entire server
  • High learning curve
  • Documentation does not cover real-world scenarios
  • Only allows you to handle a single request per time.
  • Routing requires some knowledge of regular expressions
  • Internal subcomponents coupling
  • You can deploy components together, which can create confusion.


Flask may be a relatively new framework because it has only been in use since 2010. Since the code for Flask web applications is typically clearer than that of Django, it is thought of as being more “Pythonic” than Django. The majority of beginners use Flask since it requires barricades to get a simple app up and running.

Features of Flask

Here, are the important features of Flask

  • Integrated support for unit testing.
  • RESTful request dispatching.
  • Uses a Ninja2 template engine.
  • It is based on the Werkzeug toolkit.
  • Support for secure cookies (client-side sessions).
  • Extensive documentation.
  • Google app engine compatibility.
  • APIs are nicely shaped and coherent
  • Easily deployable in production

Advantages of Flask

Here, are the pros/benefits of using Flask

  • Higher compatibility with the latest technologies
  • Technical experimentation
  • Easier to use for simple cases
  • Codebase size is relatively smaller
  • High scalability for simple applications,
  • Easy to build a quick prototype
  • Routing URL is easy
  • Easy to develop and maintain applications
  • Database integration is easy
  • The small core and easily extensible
  • Minimal yet powerful platform
  • Lots of resources available online especially on GitHub

Disadvantage of Flask

Here, are the cons/drawbacks of Flask

  • Slower MVP development in most cases,
  • Higher maintenance costs for more complex systems
  • Complicated maintenance for larger implementations.
  • Async may be a little problem
  • Lack of database and ORM
  • Setting up a large project requires some previous knowledge of the framework
  • Offers limited support and a smaller community compared to Django

Difference Between Flask and Django

Flask vs Django
Flask vs Django

Flask and Django are the two most popular Python- frameworks. Here are some important differences between Django and Flask. 


Which framework is superior is a question that many developers have in common. By this point, you may have a good understanding of each framework’s operation and recommended applications. Nevertheless, there are a lot of popular websites with large traffic that are also developed in Flask and run admirably, on par with websites developed in Django. Many fundamental ideas are shared by Django and Flask, but Django is more complex, expansive, and requires a steep learning curve. As a result, if you want to acquire a sense of how a web framework works, start with Flask and then switch to Django for more complex projects.

With Flask, you can start with some necessary programming skills, but Django needs some prior homework for you to write even a Hello World program. However, as your project structure grows, you find that adding new functionalities is more overwhelming in Flask, whereas Django would seem like a breeze. 


  • Is Flask easier than Django?

Yes, the Flask learning curve is much simpler than Django. 

  • Which is better Django or Flask for beginners?

For beginners, Flask is recommended. It is easy to learn and used for making small applications that give room for experimentation and full control access to the development process. 

  • Is Django front end or backend?

Django is a full-stack web framework that allows suitability for both back-end and front-end development.
