Flask vs Django? Many Python-based web frameworks enable developers to build websites without coding with a hundred percent scalability, and seamless interaction. More or less, talking about both the frameworks, Flask vs Django, developers have to be perfect and experienced enough to deal with the consequences and fix the bugs instantly.

A website manager is responsible for choosing the best languages and frameworks for developing many website management frameworks. According to a Python developers survey in 2018, the two most popular Python frameworks are Flask vs Django. And these two are the most popular frameworks for development.

To help you understand python Flask vs Django frameworks, I’m writing this blog with authentic information to drive the choice factor well justified. However, if you’re seeking professional web design & development services, you can choose us to do the needful.

Let’s start the conversation discussing the core difference between python Flask vs Django in detail;

What is Flask in Programming?

Before we start with Flask vs Django comparison, let’s learn what Flask is? A light-weighted framework known popularly for developing web applications. Python Flask is a microframework offering the basic features of developing a web application. Flask framework has no dependencies on external files and libraries. Moreover, the flask framework offers extensions for validations, object-relational mappers, open authentication systems to uploading mechanisms, and other development tools easily.

Flask stands between the top-most python development frameworks with a simple. Innovative and easy-to-use mechanism. So, if you’re craving flexibility in the website, then Flask can be your choice. Moreover, it comes with several libraries to learn about API through the documentation available on the website.

So, if you’re a python developer, start your core development through Flask to get an idea of both backend and frontend development.

We have an exciting blog discussing the difference between scripting and programming languages. You can give it a read to excel your knowledge.

Python Flask vs Django – Features Of Flask

Some of the top-tier features of the Flask are as follows;

  1. Flask gives the developer complete control over the decision to build the application during the implementation stage.
  2. Flask vs Django comes with a built-in development hosting server, perfect for saas website development.
  3. Easy to understand and develop.
  4. Flask is integrated with unite testing support for the developers.
  5. It’s coherent & comes with neat API integration.
  6. Flask comes with a restful HTTP request handling.
  7. Werkzueg and Jinja2 are two main strong dependencies of Flask.

What is Django? How Does Django Work Python?

Similarly, before jumping to the core Flask vs Django comparison, let’s learn what Django is? Django is a free & open-source Python web development framework. Some people also search for Marketo vs Eloqua & HubSpot vs Marketo to improve their understanding; you can read our blog to get an idea of both!

Django is a web development framework following Model-Template-View (MTV) pattern. So if you’re a developer, all you need for maintaining your online presence is a digital website. Django is free to use and has a beautiful interface.

Django vs Flask focuses on re-building and reusing components, with less coding and rapid development. The key influence behind Django development was Zope and Plone, including Pyramind, CherryPy, Bottle, and Web2py.

Python Flask vs Django – Features Of Python Django

Some of the fantastic Python Django features are as follows;

    1. Django is a versatile development framework for developing social websites, news sites, and content management.
    2. Content formatting is possible in any format like HTML, XML, JSON, and a lot more!
    3. Django is a secure framework working automatically to manage the standard security features like user account management, cross-site request managing, and clickjacking.
    4. Highly scalable and maintainable.
    5. Django follows a definite set of patterns and principles to reuse the code, and it also says ‘don’t repeat yourself,’ which indicates duplications.
    6. Django is highly portable and is well written in Python, one of the most popular programming languages.

Head to Head Comparison – Flask vs Django

Honestly, you’ll have a big hang of it a bit by now – I tried to mention all the necessary information related to python Flask vs Django. While Django is a full-fledged development framework, Flask is a micro-framework with complete control. Nevertheless, a head-to-head comparison is required to drive the discussion and make everything well justified.

Let’s start the head-to-head discussion leading towards a decision.

1. Web Development Framework

Python flask is a lightweight framework with minimal features, whereas Django is a web framework with a batteries-included approach avaliable for free. Undoubtedly Django wins here in Django vs Flask.

Flask – 0
Django – 1

2. Database Authorization

Django is a simple yet powerful ORM, supporting many relational databases out of the norm, like PostgreSQL, MYSQL, Oracle, and SQLite. Whereas Flask does not assume data storage still, there are a lot of extensions valuable like Flask SQLAlchemy, Flask-Alembic, Flask-Peewee, and Flask PyMongo. So, if you’re looking around for relational databases, then Django is the best choice as it has a built-in ORM whereas, Flask gives you the freedom to pick any ORM that best works with your application.

However, for this freedom you’ve got to pay, which is quite expensive! It’s a tie between both frameworks.

Django: 2
Flask: 1

3. Authentications in Flask vs Django

Since many web applications require basic information like authentication and authorization, Flask-login and principles are available for the users to read and understand. Django provides this complete functionality and account management, whereas and Flask offers cookie-based sessions, so you have to turn to the network extensions for account management and authorization.

The decision is relatively straightforward; Django takes the lead with built-in account management and support session features.

Django: 3
Flask: 1

4. Administration in Flask vs Django

Talking about administration in Django or Flask, Django comes with a functional admin panel, a web application providing users interface to interact with the management of databases. Flask is a way behind in administration and doesn’t ship well in flask-admin, offering a wide range of functionalities.

However, if you wish to read about Shopify vs WordPress, feel free to read out exciting blogs enriched with quality points!

Undoubtedly in Flask vs Django performance and administration features, Django wins the race with flying colors.

Django: 4
Flask: 1

5. Routing & Views in Flask vs Django

Want to know which one is best, Django or Flask in routing? Read below …

When a request matches the URL, the request object is a password to view, and that view is invoked. URLs and views can be defined in different files, whereas, Flasks uses Werkzueg, which provides the URL routing and response handling feature.

Here, Flask takes the lead against Django for routing and viewing purposes.

Flask – 2
Django – 4

6. Forms

If you’re a website manager who does website maintenance and management, you must be aware of the importance of forms. Django comes packed with forms, handling security concerns like cross-site request forgery, cross-site scripting, and a lot more themselves, whereas Flask doesn’t support this functionality by default. However, the powerful Flask-WTF extension integrates it with WTForms automatically.

Here, Django takes the win with built-in forms functionality for the developers.

Django – 5
Flask – 2

7. Reusability Of Components

Django comes with a concept of the application, whereas, Flask maintains blueprints. Django applications are complex than Flask blueprints but tend to be easy and easy to use once you’ve successfully set them up. You can easily add new developers to the Django project, whereas blueprints, on the other hand, are simple, easy to use, and set up.

Here, the choice is quite tricky, but as blueprints are easy to handle and simple to use, we’re giving one point to Flask.

Django – 5
Flask – 3

8. Templates Engines

The eighth attribute which we’ll see in this blog of python Flask vs Django is template engines. Template engines allow you to inject information dynamically to the pages from the backend. Django comes with a built-in ready-to-use template engine saving a lot of development effort and time. Whereas, Flask temple engine Jinga2 is somehow based on Django template engine.

So, again Django wins this category, and it’s an obvious win …

Django – 6
Flask – 3

9. Asynchronous Views

Honestly, Flask doesn’t support asynchronous request handling. However, Django supports the asynchronous handlers introduced recently in the Django 3.1 version. Django wins this category!

Django – 7
Flask – 3

We have a fantastic blog writing on Maya vs Blender, a tremendous head-to-head comparison to enhance your knowledge!

10. Testing Support

Talking about Flask vs Django regarding security concerns then both the frameworks comes with built-in support for testing. Both frameworks leverage python’s unit test available for requesting and inspecting the websites.

Here is a tie between the two, so giving a number to Flask and Django both!

Django – 8
Flask – 4

11. Security & Privacy

Django has quite impressive built-in protection against malicious attacks, like CSRF, XSS, and SQL injection. Django development has proactively disclosed and fixed a lot of security concerns to give users a fantastic experience.

On the other hand, Flask has a smaller codebase, so the ratio of attack is less. However, if you wish to fix those addresses, then a lot of critical thinking is required. Summing it up, Flask is much more reliant on third-party extensions, which is, of course, least secured. Whereas Django is much easier to secure upfront during the lifetime of your application. So, the extra point is for Django;

Django – 9
Flask – 5

12. Flexibility Concerns

Concerning design, Flask is more flexible, whereas Django is not! Whereas, in Flask, developers have the freedom to do whatever they want to solve any bug, but they have to pay for this. Flask generally takes more than the expected time to set up because of the appropriate extensions required to fix the business needs. However, a mature team is required to handle the Flask designing patterns and scalability.

So, the winning team is evident in this category;

Django – 9
Flask – 6

13. Responsible Resources Hiring

However, Flask vs Django are both famous, but it’s hard to hire a Django developer with complete knowledge to deal with the bugs and development concerns. Because of the rise in microservices, developers learn more about lightweight languages, picking Javascript over Python and Ruby.

Moreover, Django beginner tutorials are not available easily on the Internet, making it difficult for the users to perform all the development activities. In a nutshell, Flask developers are also hard to hire, but as it’s easy to understand, developers are more towards such frameworks, whereas Django is complicated and requires expert knowledge to develop using the framework.

Django – 9
Flask – 7

14. Performance & Speed

Talking about performance in Flask vs Django, Flask performs slightly better as it’s smaller and has few layers. At the same time, Django is a bit slow in performance.

Django – 9
Flask – 8

15. Use Cases Designs For Django vs Flask

Lastly, we have use cases attribute, so let’s see which one is more proficient, Django or Flask? Django was designed for the fast development of complex web applications, providing developers with all the necessary tools for implementing scalable frameworks. Whereas, Flask is a simple framework used for creating smaller web applications.

Django – 10
Flask – 9

Clear much? Here Django takes the lead and wins the head-to-head comparison between Django and Flask.
