Python is one of today’s most frequently used programming languages. In this blog, we are going to cover two of the most popular Python frameworks: Flask vs Django. From simple to complicated websites, these frameworks can accomplish it all. Out of the numerous widespread choices, Flask vs Django is the most talked about – and mainly because both are comparable in some ways and different in multiple other ways!
What is Flask?
Flask is a free, open-source, and lightweight web framework that is written in the Python programming language, it is used to make scalable web applications. It doesn’t rely on external libraries, though it has extensions such as open authentication systems, form validations, object-relational mappers, uploading mechanisms, and other tools. As a newcomer, it is comfortable to learn Flask as it has uncomplicated code and syntax for transforming ideas into applications. Flask is built on the WSGI toolkit and Jinja2 template engine.
Flask’s primary features include:
- Integrated support for unit testing.
- Rapid debugger and development server.
- Jinja2 template engine, a powerful web template engine.
- Werkzeug, which offers robust web server gateway interface (WSGI) support.
- Support for secure cookies at client-side sessions.
- Extensive documentation.
- Google app engine compatibility.
- Clear and neat APIs.
- Simple production deployment.
- Under 10,000 source lines of code.
What is Django?
Django which is also called the framework for fussbudgets with deadlines is a web application framework that takes care of multiple standard functionalities to create secure and maintainable websites.
Django is open-source and free, it has extremely helpful and active community support with loads of documentation. With Django, you acquire most of the things ‘out-of-the-box’ as one single product.
Django offers an abundance of integrated solutions, ready to be utilized by developers directly. This is why this framework is regarded as a business solution that is suitable for larger companies that need to accommodate high traffic.
Django’s primary features include:
- Model-View-Controller (MVC) architecture.
- Predefined libraries for graphics, scientific calculations, imaging, etc.
- Support for multiple databases.
- Cross-platform operating system.
- Compatibility with any client-side framework.
- Site optimization across specialized servers.
- Front-end tools support such as Pyjamas, Ajax, jQuery, etc.
- Multi-character and multi-language support.
What is Flask used for?
Flask works best when you want to take the benefit of its customization and flexibility capabilities. It is the correct choice when you know there will be more technical decisions to make, and you don’t want to be limited by the decisions that you have made with Django.
In this case, it can be worthwhile to depend on an efficiently customizable Flask rather than Django. Flask works well with web apps that will be divided into multiple smaller services that won’t need that much code to achieve their goals.
You can likewise utilize Flask for simple Web apps that have limited functionalities. Every Flask project has its own unique “internal tech stack” of frameworks, libraries, etc. It’s something free for all.
Flask is a wonderful fit in the following:
1) Experimentation with the libraries, architecture, and the newest technologies.
2) Unknown number of highly specialized (micro) services.
3) A group of small, disparate features.
Popular firms that utilize Flask include:
- Red Hat
What is Django Used For?
Django is used to build complicated, database-driven websites while releasing the designer from the more monotonous aspects of coding and development.
If any developer wants to create websites quickly and effectively, then they should go for Django. Django is more suitable if you’re concentrated more on the final product, particularly if it’s a specific application like a news site, e-store, or blog.
This framework has a bundle of standard functionalities that you can select and choose from. You can utilize Django for smaller projects rather than shifting to Flask. Django’s all-inclusive approach can furthermore positively impact the security of your app.
Django can be used as:
1) Django usually allows developers to create an MVP in less time than Flask.
2) Django effectively works as a “start fast” solution, providing you the capability to launch quickly and grow later.

Comparing these two frameworks – Flask vs Django
Flask and Django are the two most dominant Python- frameworks. Django is a full-fledged framework with packs of functionalities already accomplished for you, on the other hand, Flask has everything under your control. This is not the only difference; there are some more important differences between Django and Flask. These differences will help you understand which one you should choose for your web application.
1) Framework type and uses
Django is a full-stack framework based on a batteries-included strategy. You can build full-scale powerful and effective web apps in Django. The batteries are features, patterns, and tools. These can be utilized by developers for jobs such as user authentication and URL routing.
On the other hand, Flask is a lightweight framework that delivers multiple out-of-the-box services such as error handling, unit testing, cookies, and a bunch of third-party extensions. It is mostly employed for lightweight web applications where high speed is needed. Flask allows the developer to create web applications with only core functionalities.
Django’s database support is renowned as Django ORM (Object Relational Mapping), which supports databases such as MySql, Oracle, and SQLite. The ORM helps in transmitting data between the application model and the database. ORM furthermore helps in managing database migrations. This improves the pace of the development process.
Flask does not have an ORM system, and you can select the ORM that works for your app. Also, Flask needs you to conduct database operations with SQLAlchemy. So, it can be said that Flask provides you with more freedom.
Flask offers complete flexibility; it can be extended with different development tools and libraries. Flask is, thus, easier to learn as there is limited functionality, this functionality can be extended as per usage.
On the other hand, Django is a feature-packed framework. Django doesn’t permit developers to modify its module easily. Developers have no option but to utilize the tools offered by Django. Those tools are excellent but may not align with the developer’s requirements.
Flask Admin is an extension that you can utilize for incorporating administration interfaces in the applications. It is not as powerful as Django’s admin panel but permits you full control over the look and feel.
On the other hand, Django includes an in-built administration panel that can be utilized for managing all administrative tasks. This allows you to execute CRUD functions (Create, Read, Update, Delete) for your applications. Also, you can utilize this panel to control website content and handle users.
Flask does not support forms. However, its Flask-WTF extension enables you to integrate Flask with WTForms.
Next, come to Django, which comes with forms that are important parts of web apps. This is possible by the class named ModelForms that enables you to make forms without HTML code.
6) Template Engine
The template engine is what will develop HTML for a webpage. Both frameworks have identical templating engines. Django makes it more comfortable for developers to instantly write DTL (Django Template language).
Flask utilizes Jinja2 templating engine which is equivalent to Django’s templating engine.
7) Learning curve
Flask is simple to learn for beginners and you can learn the concepts as you tinker with it. But unlike Flask, Django has a steep learning curve and novices utilizing this framework might take time to perfectly use it. Nevertheless, professional programmers will find it more comfortable to understand Django than Flask.
8) Community support
When comparing both these frameworks – Flask vs Django, based on community support, Django has a big and powerful developer community where you can find developers to help you in your project.
Moreover, if you have some issue with your application, you can be sure to find the solutions on the internet as it has a ton of users.
- Flask offers support for API while Django doesn’t have any support for API.
- Django offers dynamic HTML pages while Flask does not support dynamic HTML pages.
- Django is built for easy and simple projects whereas Flask is a Python web framework built for rapid development.
- Django provides a Monolithic working type whereas Flask provides a diversified working type.
- Django framework has a URL dispatcher based on controller-regex. On the other hand, Flask web framework’s URL dispatcher is a RESTful request.
- Django is a Full Stack Web Framework whereas Flask is a WSGI framework.
Final Thoughts – Which is better Flask or Django?
There is one common question of numerous developers – which framework is better – Flask vs Django? By now you might have got a fair idea of how each framework functions and what are the most appropriate ways to utilize each of them. Flask can help you start with some essential programming skills, while Django needs some previous homework for you to write even a “Hello World” program. But as your project structure expands, you will discover that adding new functionalities is more overwhelming in Flask, whereas Django would appear like a breeze.
When it comes to the features, Django is far better than Flask – including many plugins, extensions, updates, ORM, in-built forms. The battery incorporated technique makes development even faster. It is a wonderful framework for creating complex web applications. But if you are making a small web application, Flask is also amazing and flexible. It is more comfortable to learn, has customizable admin support, and will allow beginners to make applications faster. Therefore, the battle of Flask vs. Django can be finished by stating that it all depends upon your project requirements.
The learning curve of Flask is much simpler than Django. Flask is more pythonic than Django as the code of flask Web Application in most cases is more detailed than the Django Web Application code. So, it is uncomplicated for Python coders to pick up.
Django is a full-stack web framework that permits practicality for both front-end and back-end development.
Both Flask and Django are excellent and appropriate for their purpose. Django is utilized to build more significant enterprise-scale applications. Flask is utilized to build smaller and static applications. Flask is also suitable for prototyping.
