Django Vs Flask: Which Python Framework to Choose?

Published On: 29/08/2022 | Category: Django Python

Hi Dev,

This tutorial is focused on django vs flask: which python framework to choose. I would like to share with you flask vs django which is easier. We will look at example of differences between django vs flask. we will help you to give example of what is differences between django vs flask. So, let's follow few step to create example of django vs flask for beginners.

Flask and Django are the two most popular Python-predicated web frameworks. Both are mature, open-source, and have many jubilant users. A natural question consequently is: which one to utilize?

Difference Between Django and Flask

The design of both Django and Flask frameworks characterizes them as Python-predicated, open-source, and free. These frameworks’ approach expedites the development of web applications.

Django framework gasconades about its “battery included” approach that is absent in Flask. This trait makes it more stable than its nemesis. We can consider these batteries as features, implements, functionalities, and patterns whose provision is out-of-the-box. The rigid and longer release cycles additionally account for Django’s stability. Each incipient relinquishment of the Django framework will package ameliorated features. Moreover, its vigorous rearward compatibility makes it possible for files and data from an older Django version to be utilizable in the incipient version’s environment.

Flask, on the other hand, is a master at core scaffolding. It has a plethora of flexibility in templating, URL routing, cookies, requests, error handling, debugging, and unit testing support. Most web applications demand detailed and customized authentication and sanction approaches without forgetting the desideratum for an ORM. The flexibility of Flask lets you decide on the application structure to follow as you build your application. You do not have to adhere to a default structure, like Django’s case, once you initiate an incipient project. If you are curious about the Flask source code, you will find it more facile to review. It has less code than its compatriot Django.


The comparative Django and Flask features we want to look at concern the cores of the two frameworks.


The ORM (Object Relational Mapping) in Django is simple and puissant. The fortification this ORM offers elongates to several out-of-the-box relational databases like MySQL, SQLite, Oracle, and PostgreSQL. Through the migrations in Django, a utilizer can facilely engender and manage several databases via ORM. Moreover, with an already subsisting or engendered database model, working with views, forms, and templates becomes fairly facile or straightforward. Ergo, if you have a CRUD web application in mind, the Django databases feature will make your app development period less intricate.


Authentication is an approach utilized by a web app to question the user’s identity endeavoring to access its features. It is the web app’s way of asking a utilizer the question, who are you? On the other hand, sanction is a web app’s way of asking which activities you are supposed to perform on its accessible features. It asks a utilizer the question, what concrete activities are you supposed to do here? These functionalities are available in Django with adscititious sessions’ support and account management. Django implements this feature via the utilizer model.


The serviceable admin interface is what makes Django a capable web system. Not at all like Flask, Django incorporates a yare-to-use admin system that potentiates clients to carry out the elongate organization errands consistently. Predicated on the venture, it naturally engenders admin modules. Engineers can indeed customize the admin interface in arrange to meet the particular trade needs.

Flask’s approach does not package this functionality for you. However, the viability of the Flask-Admin extension outperforms Django’s admin panel because of the numerous functionalities at its disposal. Django will automate most of your admin panel functionalities. Flask’s philosophy, however, takes an explicit approach. It lets the developer decide on what admin functionalities need to be initialized. Moreover, Flask’s approach conventionally requires the developer to craft some boilerplate code in an advanced project setting. This approach is consequential in implementing a custom logic on your web app.

Routing and Views:

The two Python frameworks accede on their fortification for class-predicated and function views and a matching approach that maps URLs to views.

In Django, the view-route relationship is as follows. An HTTP request will check if it matches with a targeted URL pattern. If veritable, the HTTP request information held by a request object passes on to its linked view. The request object then invokes the view. Ergo, accessing a requested object designates explicitly passing it around until it matches a view it can invoke.

Built-in template engine:

Not at all like Django, Flask doesn’t have a built-in layout motor. Flask is predicated on the Jinja2 format motor. Jinja2 is itself impacted by the Django format motor. Its employments coordinate a sandboxed execution environment, sanctioning engineers to expedite the advancement handle for energetic web applications. While Django incorporates a built-in format motor that sanctions engineers to make utilizer-facing layers for web applications consistently and expeditiously.

Hello, World comparison:

Flask famously features a "Hello, World" example right on its homepage. Here's how to configure it. Navigate to an incipient directory on your computer, such as a flask directory on your Desktop. Then engender a virtual environment, activate it, and install Flask.

# Windows
> cd onedrive\desktop\code
> mkdir flask
> cd flask
> python -m venv .venv
> .venv\Scripts\Activate.ps1
(.venv) > python -m pip install flask

# macOS
% cd ~/desktop/code
% mkdir flask
% cd flask
% python3 -m venv .venv
% source .venv/bin/activate
(.venv) % python3 -m pip install flask

In your text editor create a new file,, and populate it as follows:
from flask import Flask, escape, request

app = Flask(__name__)

def hello():
    name = request.args.get("name", "World")
    return f"Hello, {escape(name)}!"

Then start the Flask server from the command line:

(.venv) > env flask run
* Serving Flask app ""
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: off
* Running on (Press CTRL+C to quit)

Navigate to and there is a nice "Hello, World!" message.

In Django, There is no equipollent example on the Django website however we can, in fact, accomplish a homogeneous feat with only a few more lines of code. Navigate to another directory, perhaps called django on your Desktop. Then install Django:

# Windows
> cd onedrive\desktop\code
> mkdir django
> cd django
> python -m venv .venv
> .venv\Scripts\Activate.ps1
(.venv) > python -m pip install django

# macOS
% cd ~/desktop/code
% mkdir django
% cd django
% python3 -m venv .venv
% source .venv/bin/activate
(.venv) % python3 -m pip install django

In your text editor create a file with the following code:
from django.conf import settings
from django.core.handlers.wsgi import WSGIHandler
from import execute_from_command_line
from django.http import HttpResponse
from django.urls import path


def hello_world(request):
    return HttpResponse("Hello, Django!")

urlpatterns = [path("", hello_world)]

application = WSGIHandler()

if __name__ == "__main__":

And start Django's built-in web server with the following command:

(.venv) > python runserver
Watching for file changes with StatReloader

Django version 4.0, using settings None

Quit the server with CONTROL-C.

Navigate to Django's standard port of 8000,, to see the "Hello, Django!" message.

Awesome Features

Flask: - Lightweight codebase and no batteries - If you need a non-relational database - Add a simple website or simple API endpoint

Django: - Batteries-included - Robust documentation - Vibrant community - Powerful built-in admin - Async capabilities - Security is a priority

I hope it will help you....
