Django vs. Flask: Which Framework Should You Use?

Choosing between Django and Flask, the two widely used Python frameworks for web development, can be challenging. These frameworks offer developers the capability to develop adaptable applications that can manage websites of all levels of intricacy with ease. Ultimately, the choice depends on the specific needs of the project being undertaken.

Due to the numerous similarities between the two languages, Django vs Flask is a widely debated topic.

This post offers an overview of Django vs Flask to assist you in comprehending the applications of each.

What is Django in the Django vs. Flask Comparison?

Django, an open-source web application framework, was created to enable quick software development. In 2003, Adrian Holovaty and Simon Willison, two software developers at Lawrence Journal-World newspaper, developed Django after getting frustrated with PHP’s inefficiencies and switched to Python programming language.

Django, which is named after the famous musician Django Rheinhardt, was created by two software engineers with the intention of increasing Python’s scalability for long-term usage. Originally, the framework was built to supply a Content Management System (CMS) for web-based applications.

Django follows the model-view-template (MVT) architectural model which divides the business logic from the user interface (UI). The model is in charge of data manipulation, whereas the template deals with the presentation layer. The view serves as the intermediary between the model and the template, executing the logic and data transfer before displaying the template.

Django emphasizes component reuse and pluggability, minimal code, low coupling, swift development, and adheres to the “Don’t Repeat Yourself” principle (DRY).

When is Django the Appropriate Choice?

Django is a robust web application framework that allows developers to create web applications rapidly. It significantly minimizes the time required to undertake intricate web development projects. Django was named one of the top ten most popular web application development frameworks in the Stack Overflow 2020 Developer Survey.

Django is a web framework that empowers developers to construct user interfaces and handle back-end operations like server-side scripting, database querying, and application programming interface (API) development. By harnessing the power of this potent framework, developers can build refined and captivating web applications rapidly and efficiently.

What Types of Businesses Use Django?

Listed below are some of the businesses that favour Django over Flask:

  1. Instagram

    When Instagram sought to grow extensively, Django was one of the technologies that could enrich its efficacy.
  2. National Geographic

    NG operates its website via Django, a CMS (Custom Management System) specially designed for the company’s needs. The CMS manages the website’s modules, ads, images, and other elements.
  3. Pinterest

    Pinterest uses Django to run efficiently at its maximum capacity while also allowing for scaling as required.

Flask: What is it Exactly and How Does it Compare to Django?

Flask is a micro web framework based on Python that doesn’t necessitate the use of any specific tools or libraries, qualifying it as a “microframework.” It lacks a database abstraction layer and other components that are dependent on external libraries to carry out their functions.

Armin Ronacher created Flask and spearheaded a team of global Python enthusiasts, called Poocco.

Initially, Flask was developed as an April Fool’s Day prank in the form of a single file called, which did not necessitate any installation or configuration. However, its triumph demonstrated the potential of a framework with minimal dependencies, resulting in the establishment of Flask as a substantial project.

What are some Suitable Use Cases for Flask?

Flask is a powerful framework for web development used to create server-side applications. Its most notable feature is its ability to build applications from scratch, providing developers with faster development and run times. By tapping into the benefits of this back-end framework, developers can swiftly and efficiently develop complex and dependable applications.

What are Some Companies that Utilize Flask?

These are some businesses that choose Flask over Django:

  1. Netflix

    As a video-on-demand service, Netflix heavily depends on Flask APIs for different analytical and infrastructure functions.
  2. Reddit

    With several communities where people can connect and talk, Reddit’s micro pages are managed using Flask to a significant extent.
  3. Lyft

    By using the Flask framework, Lyft has implemented a microservices architecture that consists of discrete services that collaborate to form a comprehensive application. By integrating small, independent elements, Lyft can create a sophisticated application that is simple to manage and update.

A Direct Comparison of Django and Flask

Although Django is an all-encompassing framework that manages a significant portion of the workload for its users, Flask offers greater control on a smaller level.

Below is a brief overview of the primary distinctions between Django and Flask.

Django vs. Flask: Comparison Parameters Django Flask
Control Developers already have access to the most common features that speed up development. While maintaining control, developers can investigate the application’s core.
Administration Django includes a ready-to-use customizable admin framework. Flask does not have a tool for dealing with administrative tasks.
Time It includes a template engine, which saves time during development. Flask employs the jinja2 template engine, which consumes more time than the Django engine.
Doability It enables users to divide a single project into multiple smaller apps, making it easier to develop and maintain. Each project can be a single application with multiple models and views, and each application can have multiple models and views.
Accessibility Because of the built-in ORM technology, developers can use any database and perform standard DB functions without writing lengthy queries. In order to effectively and efficiently manage a variety of databases, Flask developers must utilise Object Relational Mapping (ORM) systems and Structured Query Language (SQL) tools, such as SQLAlchemy. Moreover, all necessary SQL queries must be written in order to complete common tasks.
Load Capacity Django is a framework for use in production (Heavy load tasks) Flask is a single-threaded program that may struggle under heavy load.
Popularity Django is more popular because it includes a lot of functionality out of the box and allows for faster development of complex applications. If you are new to web development and looking for a platform to start with, Flask is an excellent option. It is a popular choice for web development, as many websites built with Flask have demonstrated to be capable of handling a large amount of traffic, although not as much as those built with Django.
Flexibility Django is not suitable for projects with dynamic requirements. By utilising the capabilities of Flask, it is possible to make modifications to a simple application and expand its functionality. This allows for rapid development of the application, making it more complex and feature-rich.
Project size Django is best suited for large, feature-rich projects. However, for simpler applications, this language may be overkill. Simple applications can be built quickly and without much coding.
Complexity For the same functionality, Django requires more than twice as many lines of code as Flask. The Flask application requires far fewer lines of code.


Although Django and Flask have many commonalities, the decision to select a framework is determined by the project’s complexity. However, in many areas, Django exceeds Flask in terms of functionality.
