This has been the most controversial topic among flask and Django developers. There has been a war waging since both came into existence. So, let's find out what’s the difference between both of these packages.

Why is there a controversy between the two?

Both frameworks do the same work of serving for building a web-application. For example, there's always a controversy between i-phones and Andriod phones. Both smartphones do the same work, but yet the ways of doing it are different. Let's understand what is flask and Django.

What are Flask and Django?

Flask and Django both are the frameworks that are used in creating a web-application. We can create standalone websites with the help of Flask and Django. Flask is classified as a microframework because it does not require particular tools or libraries. It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions.

Major Difference

The major difference between the two is that Flask is a microframework i.e it does not have any built-in database or auth system. We have to write code from scratch or attach a third-party package to it like flask-login.

Django’s Modular approach

In Django, we can divide the whole website into apps. These apps can be used in other projects as well. Writing code in Django is pretty easy.

Talking about security

Django has provided inbuilt security feature for these problems:-

Cross-site scripting (XSS) protection

XSS attacks allow a user to inject client-side scripts into the browsers of other users. This is usually achieved by storing the malicious scripts in the database where it will be retrieved and displayed to other users, or by getting users to click a link which will cause the attacker’s JavaScript to be executed by the user’s browser.

Credentials Protection using CSRF

CSRF attacks allow a malicious user to execute actions using the credentials of another user without that user’s knowledge or consent.

Data Safety (SQL Injection)

SQL injection is a type of attack where a malicious user is able to execute arbitrary SQL code on a database. This can result in records being deleted or data leakage.

Admin Dashboard

One of the most amazing features of Django is its admin dashboard feature. It provides an in-built Admin dashboard where we can perform CRUD operations. This is an example of the Admin Dashboard Django.

As far as flexibility is concerned, Flask seems to have a complete win over django. Flask is flexible allowing its users to use frameworks according to there needs.


Well as far as performance is concerned both deliver pretty good standards with there work.

Decetralizatoin of Code

When a product grows it becomes absolutely necessary to deliver the content to the users at a faster rate. A user will never stay on your website if the response time is more than a min.

An example of Mircoservcies also referred as decentralization here.

Which one to choose?

We have only talked about the advantages of Django. Now, let’s take a while to understand flasks usage. As discussed earlier, if you want to have full access over your website its good to go with flask. But this doesn’t promise code reliability, reusability, modular approach. Django is built in a way where we are bound to follow good programming standards.
