StackOverflow reports that Python is currently at the height of popularity. It’s simple, versatile and a fit for the purpose in areas like web development, data science, DevOps, and more. Python is a choice of many companies, including Netflix, Instagram, and Dropbox among others. Those are highly loaded sites that process millions of user requests per day, and Python is central to sustaining their top-notch performance. To make the most of Python’s ecosystem, read more on Python frameworks. 

Choosing the best Python web framework

Frameworks are the foundation of web development. Choosing one largely depends on the type of app you intend to develop. 

Django and Flask are the top Python frameworks so far. When the tradeoff boils down to these two, the majority would go with Django. Flask is mostly chosen by those who for some reasons cannot use Django. Yet each framework comes with functions that you might find suitable, depending on the needs of your project. 

Django and Flask represent two major categories of frameworks, full-stack frameworks and microframeworks (sometimes called non-full-stack), respectively. 

Choosing a full-stack framework, you will have a variety of tools and packages at hand to develop any kind of application. Those are MVC architecture, ORM, routers, templating engine, security, and more. Full-stack frameworks are sizeable because they contain several modules, components and services.

A micro framework, on the other hand, fits into a single code source file. As such, it’s used whenever minimum coding is required like small applications and REST-based apps. Microframeworks lack functionality but they can be extended with databases and templating engines.

If you need to develop a feature-rich system, it’s best to choose one of the full-stack frameworks. A micro-framework is a good choice for small and mid-sized projects, prototyping, and learning the structure of frameworks.  

Making a decision, be mindful of the project’s future. Perhaps what seems like a small project today will evolve into a high traffic website. Or you will want to add a slew of functions to it, following the ever-changing market needs. 

Python web development: Full-stack frameworks


Python web developmen - Django

A full-stack framework, Django perfectly suits large, complex projects. It stands out as an excellent solution thanks to a huge amount of commonly used functions, which eliminates the need for stand-alone libraries. The framework includes authorization, URL routing, a template engine, ORM for interaction with databases, admin interface, email service, and many more. All of this makes Django a scalable and versatile framework.  

Reasons why Django is so popular: 

  • A vast ecosystem of functions
  • Time-tested
  • SEO optimized
  • Pluggable
  • Highly scalable
  • Secure
  • Regularly updated


Python web developmen - Pyramid

Pyramid is a minimalistic “open-source” framework that suits both large apps (for example CMS) and small prototypes with Python. Its goal is to do more with less effort – very much in the spirit of Python. Pyramid excels at URL generation, API development, configuration extensions, testing, and data documentation. It is open source and completely free.


Python web developmen - Web2Py

Web2py a scalable, highly secure open-source environment written in Python. This framework is designed for the development of secure applications based on databases. 

Web2py is also a powerful tool for data processing. It’s incompatible with Python 3 but works with Windows, MacOS, Google App Engine environments. This framework comes with a web IDE for code editing, debugger, and one-click deployment capability, error tracking ticket system. 


Python web developmen - Turbo Gears

TurboGears is a data-driven framework for web applications used for creating extensible web applications. TurboGears comes with comfortable templates and a powerful and flexible ORM. TurboGears’s most important functions include multiple database support, Pylon support, validation for FormEncode, command line tools, and function decorator. 



Python web developmen - Flask

The idea behind Flask is creating a solid foundation for fast scaling of a web project. It’s a perfect choice for rapid prototyping and stand-alone applications.

Flask is a microframework, which means it is more focused on simplicity and less on functions. The microframework Flask is based on the Pocoo projects Werkzeug (utility library for Python) and Jinja2 (template engine). Because Flask is a lightweight modular framework, it can be adapted to a variety of tasks. It has a number of useful features, such as an integrated development server and a quick debugger, Jinja2 template engine, support for secure cookies, the ability to connect any ORM.


Python web developmen - Bottle

Minimalistic by design, Bottle is a good fit for small projects and prototyping. It consists of a single source file. Other than a standard Python library, this framework has no external dependencies. 

Bottle is faster than many of its competitors, but it lacks functionality needed for large projects. It has a built-in HTTP server, routing with support for URL parameters, template support, convenient work with forms, downloading files, debugging in “debug” mode.


Python web developmen - CherryPy

CherryPy is known as a lightweight, object-oriented framework. It allows to create stand-alone applications capable of embedding its own multithreaded server. CherryPy apps run on any OS that supports Python. With CherryPy, there’s a possibility to use any technology for templates, process articles, cookies, download files, and more. CherryPy has a built-in plugin system and support for the profiling, testing, and coverage, ability to run multiple HTTP servers simultaneously, a configuration system, and out-of-the-box cashing, decoding, authentification, static content processing, and more. 


Hug Microframework

The fastest Python 3 platform, Hug makes API development succinct by offering a variety of interfaces. Hug encompasses support for automatic documentation, annotation-based validation integrated version control, and can be used as a library in other Python applications. The Hug environment assumes little integration and coding while remaining functional and highly performing. The community is expanding, so you will get all the needed support.

google use python

Python is an indispensable part of Google as we know it. It was a relatively young language when Google decided to adopt it. In fact, Google’s entire stack and first search language were written in Python. The language is extensively promoted by Googlers who are the main contributors to the language. 

Google uses a variety of languages on the server-side, including C++, Java and Go. Python became part of elements that required fast delivery and easy deployment and maintenance. Google App Engine is written in Python and still remains a great example of Python application. 


dropbox use python

Dropbox’s entire stack was written in Python, and they started using Go later on. The company even pulled the Python creator, Guido van Rossum, from Google where he had been employed for years. He joined Dropbox as an engineer and made it possible to share datastores between members of Dropbox community. Lots of company’s libraries are not open source, so it’s hard to say the extent of Dropbox’s reliance on Python. However, the company released an API written in Python and we can assume that a huge amount of server-side code is also written in Python.


instagram use python

In 2017, Instagram migrated to Python 3, and now is using it at full scale, relying on Django-Python architecture. A few years ago, the engineering team voiced reasons why Python became their primary choice. The main reasons why the company chose Python were simplicity, efficiency, and practicality. For a rapidly growing company, these things are extremely important. With Python, developers didn’t have to struggle with the language and focused on developing features we all can enjoy today.

Instagram considered migrating to PHP, but after some deliberation, they realized that it won’t improve performance significantly. The company decided to bet on Python because each new update brings improvement to the speed.
