Flask vs Django: Top 10 Differences You Should Know

Do you want to know which framework, flask vs Django, is better for web development? Many python-based web frameworks make it easy for developers to quickly create scalable apps. These frameworks can handle everything from simple to complex websites. Django vs Flask is the most talked-about of the numerous popular options, and for good reason: they are similar in some ways and different in others! This leads to a comparison of the two, and while each of these web development frameworks has its own set of characteristics, there are a number of things to consider before selecting one for your apps. 

On the one hand, Django is a full-featured web framework, whereas Flask is a lightweight and extensible framework. Flask helps you understand how each component from the back-end works to get a small web application up and running if you want to dive deeper into coding and master core principles. Django follows a lot of design patterns, so you’ll pick up a lot of new ideas. Furthermore, both frameworks have extensive community support and documentation, so if you ever come into a problem, it’s likely that it’s previously been addressed and resolved- making your job easier.

Django is heavyweight, whereas Flask requires you to construct everything yourself. Django has been around since 2005, while Flask came up roughly five years later in 2010. Both frameworks, however, are today’s top python frameworks. The quantity of questions people ask about these frameworks in various tech forums shows their growing popularity.

If you have a working knowledge of python, you can work on any of the frameworks. We’ve provided a simple review of both Django vs Flask for your convenience. So you can better understand the differences and applications of each. In this blog, you will learn the differences between flask vs Django. I hope you will understand flask vs Django easily.

What is Flask?

Flask is a lightweight framework that is commonly referred to as a micro framework. Flask has several basic features and lets developers add as many libraries or plugins as they like to an extension. Flask should be your first pick if you have a simple, innovative use case that needs to be added to an existing application. Flask comes with a small collection of easy-to-learn APIs and comprehensive documentation. Start your web development with Flask if you’re new to python. So you can acquire a feel for both the backend and frontend and grasp the essential ideas.

  • In most cases, MVP development is slower.
  • More complicated systems have higher maintenance expenses.
  • Larger implementations require more complicated maintenance.
  • Async could be a little problem.
  • Lack of database and ORM
  • Setting up a large project necessitates considerable familiarity with the framework.
  • When compared to Django, it provides minimal support and has a smaller community.

What is Django?

Django is a web application framework that handles many standard features needed to create secure and maintained websites. All you have to do as a developer is build your business logic. Django is a free and open-source programming language with a thriving community and extensive documentation. The name Django was given to the project in July 2005. The majority of things come ‘out-of-the-box with Django as a single product. As a result, there are no concerns with integration.

What Are The Features of Django?

Here are some features of Django:

  • It’s a flexible framework that can be used to build any website (social network, news site, content management system, and so on) with the content in HTML, XML, JSON, and other formats. It can be used in tandem with any client-side framework.
  • It’s a safe framework that takes care of things like user account management, transaction management, cross-site request forgery, clickjacking, and other security concerns.
  • It’s scalable and easy to maintain. To reuse and maintain the code, Django follows design patterns and principles. There are no duplications because the basic principle of ‘don’t repeat yourself’ is followed. Because Django is a component-based framework, each layer is self-contained, allowing the application to scale at any level.
  • Django is a lightweight programming language. It’s written in python, which is now the most popular cross-platform programming language.

What Are The Advantages of Django?

Here are some advantages of Django:

  • Django is simple to set up and use.
  • It provides a user-friendly interface for a variety of administrative tasks.
  • It has a built-in internationalization system that allows it to provide multilingual websites.
  • End-to-end application testing is possible with Django.
  • Allows you to create an HTML output to document your API.
  • Several authentication protocols are well supported by the REST framework.
  • It’s used to limit the number of API calls from a single user.
  • Allow you to set patterns for your application’s URLs.
  • It comes with a built-in authentication system.
  • Multiple caching techniques are included in the cache framework.
  • Framework for quick web development at a high level.

What Are The Disadvantages of Django?

Here are some disadvantages of Django:

  • It’s a monolithic platform.
  • Django ORM is heavily reliant. A broad range of knowledge is required.
  • There are fewer design decisions and components to deal with.
  • Compatibility with the latest technology
  • For simple solutions, a higher entry point 
  • The larger the code, the better
  • For small projects, it’s too bloated
  • ORM templates and underpowered templating
  • The entire server is restarted when you use auto-reload
  • The learning curve is steep
  • Real-world scenarios are not covered in the documentation
  • Allows you to only process one request at a time.

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.
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.

Conclusion: Flask Vs Django

In this blog, you have learned the difference between flask vs Django. I hope you have understood about flask vs Django. The majority of developers have one common question- which framework is better. By now, you should have a good concept of how each framework works and the best ways to use each one. However, many high-traffic websites developed using Flask function admirably and are equivalent to those produced with Django. Although Django and Flask share many fundamental concepts, Django is more complex and large, requiring a steep learning curve.

If you want to feel for a web framework, start with Flask and then move on to Django for more sophisticated applications. Alternatively, you can master one and then switch when your job requires it rather than learning everything at once.

You can start with some basic programming abilities with Flask, but Django requires some preparation before you can develop even a Hello World program. However, as your project structure expands, you’ll notice that adding new functions in Flask becomes more complex, whereas adding new functionalities in Django appears to be a breeze.
