Django Vs Flask- What is The Difference Between Django & Flask?

Django and Flask are both python frameworks. Both of the frameworks are used to develop web applications and they have their own advantages and disadvantages.

So, in this tutorial, we will be learning about Django and flask and their differences point by point as below.

  1. Introduction
  2. Key differences between Django and Flask
  3. Performance-wise differences
  4. Package requirements
  5. Community Experience
  6. Security patches
  7. Advantages
  8. Conclusion

1. Introduction

In the introduction we will be learning about what is Django and what is flask mainly we will go through what is the concept exactly so firstly we will start with Django and then we will see about the flask.


Django is a Python web framework, it is open source and free to use, Django mainly follows the MVT approach, here MVT stands for Model View Template, this MVT approach is for structural design. It is a high-level Python framework, so basically, Django is used to develop websites.


Flask is also a python framework. Flask is a smaller scale application, It doesn’t depend on external libraries, as we already know that Django builds websites and flask also builds websites.

2. Key differences between Django and flask

To understand more about Django and flask we need to know about the key differences between Django and flask.

  • The main performance-wise difference between Django and flask is Flask doesn’t support dynamic HTML pages and Django offers dynamic HTML pages.
  • Talking about the development, Flask could even be a Python web framework built for rapid development whereas Django is formed for straightforward and simple as well as complex projects. This will give us an exact idea about which framework to choose according to our requirements.
  • Another difference is about the working style i.e Flask offers a diversified working style while Django offers a Monolithic working style.
  • URL dispatcher of the Flask web framework could even be a RESTful request on the choice hand, URL dispatcher of the Django framework is predicated on controller-regex.
  • Regarding framework, type flask is additionally a WSGI framework while Django is Full Stack Web Framework.

3. Performance-wise differences

Performance is the main point while discussing the differences between both of them so we see exactly what are the performance differences between Django and flask

  • As we already mentioned, performance is very important so Flask vs Django performance is a crucial indicator of system functionality.
  • The performance also depends upon how the framework is secured and its speed and whether it is scalable. If the framework works all right, the result’s a scalable, fast and secure application.
  • In previous points, we discussed what is needed for good performance but in this topic, we will see what result will come if things are maintained properly. Poor performance can cause scaling and architecture issues.
  • When we consider that Django vs Flask performance has good results and is employed by high traffic websites, that’s an honest indicator of its effectiveness and this is what we wanted.

4. Package requirements

  • Flask is minimalistic and has no restrictions, meaning developers can implement exactly what they need using external libraries.
  • This makes Flask flexible and extensible. Django, on the opposite hand, includes a huge number of built-in packages.
  • There are many packages in Django whereas for flask we need to use external packages. To be precise, there have been 4,046 Django packages as of September 2019.
  • This implies you’re likely to find a package to create and run your application with less effort.

5. Community Experience

  • Another main thing coming now is the developer, which plays a huge role in solving the newcomers’ and other developers’ issues. In the case of Python Django vs Flask comparison, Django includes a huge and active developer community.
  • If you have any questions, you’ll be able to ask them on various web portals and forums like StackOverflow and are likely to get a solution. This is where there is a spread of knowledge. In general, giving others knowledge is a very great thing, so this helps other developers learn new things.

6. Security patches

  • After the performance is security, security features play an essential role in increasing the use of the framework. Django’s options for safeguarding your application from subsequent issues: Cross-site scripting (XSS).
  • Protecting from attack is also an important part.XSS attacks restrict an attacker to inject client-side scripts into browsers. Django templates protect your project from XSS group attacks.
  • Cross-site request forgery (CSRF). Django has built-in protections against most varieties of CSRF attacks. SQL injection.
  • SQL injection is an attack where a malicious user is ready to execute arbitrary SQL code on a database.
  • Data leak is a very big issue in most of the framework and it affects too much framework growth, so securing data is a very important thing. The Flask-Security library provides almost identical mechanisms to Django to stop data leaks and other web attacks.

7. Advantages


  • In Django, we can simply do the setup and work on it
  • Django provides a different User interface to handle different administrative tasks
  • In Django, we can test end-to-end testing
  • It provides its authentication system
  • Django is a high-level framework
  • Django consists of REST Framework, which helps us to build robust APIs


  • Flask can be used more simply in small projects
  • We can simply handle routing URLs
  • Flask provides a simple database integration
  • High scalability
  • High compatibility


In this tutorial, we learned about what Django is and what flask is with their introduction with key differences. We also learned about which framework is preferred for which application; we also saw the advantages and disadvantages of Django and flask.
