Top 5 Apps Built with Python 

Released in 1991 by Guido van Rossum, Python has evolved from a simple scripting language to a feature-packed programming language with extensive community support.

Owing to its easy-to-use syntax and easy learning curve, the usage of Python has grown in the last few years, outstripping Java as the most popular programming language in the 2021 TIOBE Programming Community index.

Even the biggest players in the tech landscape that need no introduction such as Facebook, Reddit and Instagram use Python in their mainstream applications.

Through this post, we’ll shed light on some of the popular apps that use Python. Without further ado, let’s begin with a quick overview of Python:

What is Python?


Python is an interpreted, object-oriented, high-level and general-purpose programming language.

  • ⦁ Interpreted: It means that the interpreter executes the code line by line, making it easier to debug.
  • ⦁ Object-oriented: It means that Python is a programming language based on the concept of “objects”, making programming easy to execute, reuse and maintain.
  • ⦁ High-level: It means that Python is a programming language with strong abstraction from computer instructions, making it easier to use.
  • ⦁ General-purpose: It means that Python can be used to engineer a diverse range of applications and isn’t restricted to solving a specific problem.

The programming language encompasses many third-party modules and extensive support libraries that make it ideal for complex application development.

Even recent studies highlighted that Python was the top five most widely used languages among software developers around the globe in 2021.

Top 5 Apps Built with Python

Now that we’ve enlightened you on what Python is and its popularity, it’s time to explore some of the popular apps built with Python.

1. Facebook


The most widely used social media platform Facebook is one of the apps built with Python.

Python is the third most used programming language for production engineering at Facebook, after PHP and C++.

According to a 2016 post by Facebook, Python powers 21% of the codebase and it is behind multiple services including TORconfig for handling network switch setup & imaging, Dapper for scheduling & automating the implementation of maintenance work and among others.

2. Instagram


One of the fastest-growing social media platforms, Instagram is also powered by Python.

“Instagram currently features the world’s largest deployment of the Django web framework, which is written entirely in Python.” – Instagram’s engineering team

The reason behind choosing Python for Instagram for the language’s simplicity matches well with their philosophy of “do the simple things first”.

3. Spotify

Spotify, the leading music streaming platform all over the world, makes use of the Python programming language for two main segments: backend services and data analysis.

Spotify’s backend encompasses many interdependent services which are connected by a message protocol over ZeroMQ and around 80% of the backend services are engineered in Python.

Moreover, Spotify has a heavy reliance on analytics to provide recommendations and suggestions for its users. The company makes use of Luigi, which is a Python module, for data interpretation.

There are two driving forces behind why Spotify chose Python: the language’s capability to expedite the development and active community around it that Spotify supports.

4. Netflix


Another app built with Python is Netflix which has become a go-to destination for people around the world to stream movies and TV shows.

“We use Python through the full content lifecycle, from deciding which content to fund all the way to operating the CDN that serves the final video to 148 million members. “- as per the Netflix Technology Blog.

While the engineers at Netflix are given autonomy to pick the language they would like to work in, most of them prefer to write in Python. The reasons behind this inclination towards Python are its standard library, the rich catalog of third-party libraries, simplicity and the active development community.

5. Reddit

Reddit, the leading social news aggregator and forum platform, is one of the apps built with Python. Originally, it was written in Lisp but made a switch to Python in 2015.

There were two reasons behind the switch to Python for Reddit. Firstly, Python comes with a wide array of code libraries. The second reason for Reddit for choosing Python was its high readability.

“The biggest thing that has kept us on Python … well, there are two huge things. One are the libraries. There’s a library for everything. We’ve been learning a lot of these technologies and a lot of these architectures as we go. The other thing that keeps us on Python, and this is the major thing, is how readable and writable it is. ” – According to Huffman, co-founder and CEO of Reddit.
