Flask vs Django - Which Python Framework to Choose?

Due to its simple syntax and high expressiveness, Python is extremely popular among developers and is often the technology of choice when implementing a wide variety of web applications. An important decision, which should be made already at the stage of planning the development of such an application, is the choice of an appropriate framework. Many developers rely on Django, but there is no shortage of supporters of Flask. How are they different and which one is better?

Top Python frameworks you can choose from

While using a framework when developing a web application in Python is not necessary, it is certainly recommended. The framework provides many useful features and components so that developers do not need to reinvent the wheel and create everything from scratch. As a result, they significantly reduce the time of project implementation and, consequently, related costs.

When deciding to implement a web application in Python, you will have at least a few different options to choose from, including Django, Flask, Pyramid, CherryPy, Grok, TurboGears, Web2Py, Bottle, and Tornado. Each has its own advantages and disadvantages and each works better or worse in specific types of projects.

Flask vs Django. And the winner is...?

Django and Flask are probably the two most popular and sought-after frameworks today. Django works better for large-scale projects, and those that plan to scale in size as the number of users grows in the future. For this reason, it is chosen more often.

Django's most frequently cited strengths include speed of deployment, as large web applications are very complex and Django significantly reduces implementation time. Versatility, as Django has proven to effectively meet all business needs whether building a social network, corporate application, or e-commerce platform. And security, as the framework effectively deals with common problems including inter-site query forgery and clickjacking.

Flask is classified as a micro-framework, characterized by little to no dependencies between external libraries. It is simple, flexible and provides granular control - allowing you to decide for yourself how to implement the various elements.

Big companies and their framework selections

Flask, despite the fact that it works well for small ventures, is kept by many large and well-known corporations in its technology stack, including Netflix, Zalando, Reddit, Airbnb, Mozilla, Uber and Samsung.

Due to its versatility and high scalability, Django is perfect for large and complex projects. Django was used to create web applications such as Disqus, Instagram, YouTube, Spotify, Pinterest, Mozilla, and Dropbox.

Adjust your decision to your project specification

In all situations, the framework should be maximally tailored to the needs posed by the project being implemented. For larger projects, complex and more heavily frequented web applications, Django generally performs better. Flask should be the framework of first choice for small projects. When deciding which one to choose, be sure to take into account any plans to expand your application.
