Flask vs Django – Difference Between Them

Key Difference between Flask and Django

  • Flask provides support for API, while Django doesn’t have any support for API.
  • Flask does not support dynamic HTML pages, and Django offers dynamic HTML pages.
  • Flask is a Python web framework built for rapid development, whereas Django is built for easy and simple projects.
  • Flask offers a diversified working style, while Django offers a Monolithic working style.
  • URL dispatcher of the Flask web framework is a RESTful request on the other hand, the URL dispatcher of the Django framework is based on controller-regex.
  • Flask is a WSGI framework, while Django is a Full Stack Web Framework.

What is Flask?

Flask is an micro framework offering basic features of web app. This framework has no dependencies on external libraries. The framework offers extensions for form validation, object-relational mappers, open authentication systems, uploading mechanism, and several other tools.

What is Django?

Django is a web development framework for Python. This framework offers a standard method for fast and effective website development. It helps you in building and maintaining quality web applications. It enables you to make the development process smooth and time-saving.

It is a high-level web framework which allows performing rapid development. The primary goal of this web framework is to create complex database-driven websites.

Difference Between Flask and Django

Flask and Django are the two most popular Python- frameworks. Here are some important difference between Django and Flask.

Attributes Flask Django
Launch Year Created in 2010 Created in 2005
Framework Type Flask is WSGI framework. Django is a Full Stack Web Framework.
API Support Flask provides support for API. Django doesn’t have any support for API.
Virtual Debugger Support Visual Debug. No support for Visual Debug.
Database Support Flask allows you to use multiple types of databases. Django doesn’t offer multiple types of databases.
Forms Flask has no default support for forms, but you can use WTForms to fill the gap. Django comes Form with which can be integrate with the ORM and the admin site.
Dynamic HTML Flask does not offer dynamic HTML pages. Django offers dynamic HTML pages.
Routing and Views The request based object is imported from the flask module, which is a global variable in Flask. All views are set as an individual parameter in the Django.
Flexibility Flask is much younger platform compared to Django. Django is a very mature framework.
Working Style Flask offers a diversified working style. Django offers a Monolithic working style.
Control It supports an extension which could be implemented in the framework. Django has its own module library. So, it stores several prewritten codes.
Structure The structure of the project layout for Flask web framework is random. The structure of the project layout for the Django is conventional.
Template Engine Flask web framework uses a Jinja2 template design. Django web framework helps you to utilizes the View web templating system.
URL Dispatcher URL dispatcher of the Flask web framework is a RESTful request. URL dispatcher of this Django framework is based on controller-regex.
Bootstrapping Tool Flask does not offer a built-in bootstrapping tool. Django-admin enables developers to start building web applications without any external input.
Project Layout Flask framework is suitable for single application. Django framework allows developers to divide a project into multiple page application.
Third-Party App Support Flask Web Framework doesn’t offer support for third-party applications. Django Web Framework supports a large number of third-party applications.

Best Features Best features of the flask is it is lightweight, open source, and offer minimal coding for developing an application. The best features of Django are Rapid development, Open source, Great Community, Easy to learn.

Advantages of Flask

Here, are pros/benefits of using Flask

  • Higher compatibility with latest technologies
  • Technical experimentation
  • Easier to use for simple cases
  • Codebase size is relatively smaller
  • High scalability for simple applications,
  • Easy to build a quick prototype
  • Routing URL is easy
  • Easy to develop and maintain applications
  • Database integration is easy
  • Small core and easily extensible
  • Minimal yet powerful platform
  • Lots of resources available online especially on GitHub

Advantages of Django

Here, are pros/benefits of Django framework:

  • Django is easy to set up and run
  • It provides an easy to use interface for various administrative activities.
  • It offers multilingual websites by using its built-in internationalization system
  • Django allows end-to-end application testing
  • Allows you to document your API with an HTML output
  • REST Framework has rich support for several authentication protocols
  • It is used for rate-limiting API requests from a single user.
  • Helps you to define patterns for the URLs in your application
  • Offers built-in authentication system
  • Cache framework comes with multiple cache mechanisms.
  • High-level framework for rapid web development
  • A complete stack of tools
  • Data modelled with Python classes

Disadvantage of Flask

Here, are cons/drawback of Flask

  • Slower MVP development in most cases,
  • Higher maintenance costs for more complex systems
  • Complicated maintenance for larger implementations.
  • Async may be a little problem
  • Lack of database and ORM
  • Setting up a large project requires some previous knowledge of the framework
  • Offers limited support and smaller community compared to Django

Disadvantage of Django

Here, are cons/drawback of the Django framework

  • It is a monolithic platform.
  • High dependence on Django ORM. Broad Knowledge required.
  • Fewer Design decisions and Components.
  • Compatibility with the latest technologies
  • A higher entry point for simple solutions
  • The larger size of the code
  • Too bloated for small projects
  • Underpowered templating and ORM
  • Templates failed silently
  • Auto reload restarts the entire server
  • High learning curve
  • Documentations does not cover real-world scenarios
  • Only allows you to handle a single request per time.
  • Routing requires some knowledge of regular expressions
  • Internal subcomponents coupling
  • You can deploy components together, which can create confusion.

Conclusion: Flask Vs Django

  • You should prefers flask if you want the granular level of control while a Django developer relies on an extensive community to create unique website.
  • Django combined with the REST Framework helps you to build powerful APIs, whereas Flask requires more work, so there are high chances to make a mistake.
  • The best method is to build a few basic CRUD apps with both frameworks and decide which framework fits your project style better.
