Top 11 Apps Developed With Python

Coding on pc

To develop fast and performative web applications, it is important to choose the right technology stack. Choosing the wrong scripting language or framework for development can lead to redesigning everything from scratch which can cost you a lot of money and time.

The programming language you choose must be able to provide all the features that you require now and later on when you scale. One such language is Python. 

More and more companies from different domains and backgrounds are preferring to use it over other languages.

So, the question is why these companies are choosing Python?

Well, Python is a powerful yet easy-to-learn programming language. It comprises versatile features that come from its frameworks and built-in libraries to serve any domain. Also, the syntax of Python is simple. This makes it easier for developers to learn and understand when working in big teams.

And this is why cloud storage, social media platforms, online booking systems, music, video streaming systems, etc. are choosing Python for development. To understand how these domains have incorporated Python for development, we have a list of companies from different domains using Python. 

If you are an entrepreneur thinking of developing an app with Python, this list of companies that use Python will inspire you on how they are using Python and for what purposes.

1. Google

Python is one of the official server-side languages of Google. Google uses Python for its app engine. Google App Engine allows building web applications with Python programming language. 

Not only that, but Google AdWords also uses Python. So whenever a user types a keyword, there are chances that they have a history in their cookies, that is when it goes over these AdWords. The process of how these AdWords communicate with the web surfers is based on Python. 

Python also assists customers to get their Adwords accounts so that they can figure out where their commercials will go. Google uses Python because of its scalability, speedy deployment, and readability.

2. Netflix

Python is extensively used by Netflix, be it security tools, recommendation algorithms, or content distribution networks. Netflix’s network devices are managed by a Python application that maintains an inventory of the devices and manages their status and location.

Netflix uses machine learning for hundreds of tasks. It uses a meta flow and Python framework to execute machine learning projects from prototype to production stage.

Here, meta flow leverages parallel programming and optimizes Python codes to handle memory and computation over hundreds of CPUs. Netflix developers use Python in their statistical analysis tasks as well.

3. Facebook

Python plays a vital role in the infrastructure management of Facebook. Services like network switch setup, imaging, auto-remediation of server hardware failure, automating maintenance work, fault detection, etc.

Python’s simplicity provides engineers with an interactive and reliable interface. This way the amount of code that they have to write and maintain can be minimized and more emphasis can be given to integrating services into their respective infrastructure.

4. Spotify

Spotify uses Python for backend services, scripts, data analysis, etc. Python is the first choice because of its fast speed of project development. Spotify uses a Python framework for I/O-based services as well. If you plan to develop a music or video streaming app, hire dedicated Python developers for your project and it will deliver results better than your expectations.

5. Quora

Quora chose Python because of the following reason. Python is a readable language that makes working with a bunch of people a bit easier. There are many libraries written in Python, making it possible to incorporate things like task queues, custom mail servers, etc. into the rest of your codebase. Also, Python's data structures map well with JavaScript data structures. So using these two between the browsers and server becomes easy.

6. Dropbox

Dropbox was able to share data stores with its other users within the Dropbox community. Dropbox was able to code efficient APIs in Python. Most of the Dropbox libraries are also coded in Python and they make use of it both on Mac and Windows machines to allow a unified experience. 

7. Reddit

Reddit started using LISP as their main language and soon realized that Python would be more suitable for their platform to handle the growing number of users. Reddit founders also gave the reason why they shifted to Python. 

The first reason was that Python has a huge number of libraries. The other reason was that Python works as a common thread that can run through all the companies who are using it. Also, the readability and ease of Python attracted developers of Reddit. If these features of Python attract you as well, you can hire Python developers and take the best advantage of all these functionalities.

8. Instagram

Instagram initially chose Python because it has a reputation for being simple and practical. Instagram has built an efficient framework for web services. They can handle the resources efficiently with the help of Python. They also profiled the Django server by developing the Dynostats tool for sampling user requests and gathering performance metrics.

They wanted a technology that would help them scale their infrastructure in the future as well. They chose Python to handle a huge number of active users efficiently. As per the reports, they had over 2 billion active users in 2021. They have also migrated their code to the latest Python 3 as well. 

9. Pinterest

Pinterest started using Python from day one. Pinterest’s original stack was made with Django and Python. Pinterest had 431 million monthly active users in the last quarter of 2021. Thus, Pinterest chose Python as one of the languages to deal with a heavy number of active users. 

10. Uber

Python is one of the dominant programming languages used in the development of Uber. Most of the main service processes run on Python as of today. Python also helped Uber to access their visualization frameworks.

11. YouTube

Python is almost everywhere on YouTube. It uses Python for different purposes like viewing videos, controlling templates for websites, accessing canonical data, and more. 

So, if you are interested in developing something similar to or inspired by the list of companies discussed above, hire dedicated Python developers. You will surely not regret incorporating it into your project.


The giant companies we discussed above have grown so much in these years and this proves that Python is highly scalable. This is the reason Python is excessively used for game development, machine learning, data science, application development, etc. Hence, if you wish to develop something that can scale smoothly like the companies we discussed, hire Python developers and make the best use of libraries and the framework for your next project. Python will surely open the door of opportunities for you to deliver something different to this world.
