I started as a newbie web developer in 2005. More than a decade has passed, and I’ve tried many different coding languages. 

We’ve used a few different web and mobile frameworks in our agency, but we never changed the primary programming language.

We always used Python for the backend here at SoftFormance and didn’t regret it once. 

In this article, we demonstrated all the pros and cons of using Python for web applications development.

And today, we’d like to continue exploring Python’s use in the real world.

So, we prepared for you the most comprehensive list of web apps and popular software built with Python language.

You’ll be surprised to learn how many modern businesses and organizations use Python as their go-to language. 

And we went an extra mile with our team and grouped these projects into a couple of buckets:

  • Big Five Companies
  • Streaming services
  • Software as a Service (SaaS)
  • Web platforms
  • Social media networks
  • Game industry
  • Science
  • Graphics and Design

So enjoy!

Big Five Companies

Also known as Big Tech or Tech Giants. These are the companies everyone knows about (or at least recognize their logo), from a retired librarian to a child in a kindergarten.

And three out of five use Python to build and run their systems.

Google needs no introductions because it’s the most popular search engine in the world. Google has more than 75% of the market share. 

When choosing a programming language, the company’s engineers decided to use Python where they could and C++ where they must. 

Why? Because of Python’s readability and maintainability. It allows Google, one of the greatest apps made in Python, to carry out a variety of its projects successfully.

In 2021, Facebook had nearly 3 billion active users monthly. It’s hard even to imagine this number, but what about this: it’s as if all people from 6 Northern American continents used Facebook. Impressive, huh? 

The company is huge, as well as its tech stack. Facebook uses many programming languages and technologies, and Python is one of them. In particular, the company claims that Python was used to build about 21% of Facebook’s infrastructure’s codebase. 

What exactly is Python incorporated for? It allows Facebook users to upload pictures, posts and update statuses. So every time you post a new photo with your dog or update your audience about a recent career change, thank Facebook for that.

Streaming services

Streaming services were gaining popularity lately, but the outbreak of COVID-19 gave them a boost. Stuck in their homes, people had nothing better to do than binge-watch their favorite shows or listen to their favorite albums on repeat. 

And it turns out that the giants in the streaming services industry, Spotify and Netflix, also use Python.

With Spotify, you can instantly access tons of tracks and albums with virtually no buffering delay. The platform was released in 2008 and has reached more than 75 million paid subscribers in less than two decades. 

Spotify’s website is built using WordPress, but the mobile app is built with Python. Also, Spotify’s engineers used it to code the app’s backend. Specifically, the app’s backend consists of many interdependent services connected by their messaging protocol. And around 80% of those services are written in Python.

Netflix became the leading internet television network with a coverage of 40 countries and more than 33 million members. In total, the service is used for more than one billion hours of TV shows every month. That also includes Netflix’s own production. 

No doubt that Netflix developers have the best possible technology at their disposal. And most of them use Python because of its rich batteries-includes the standard library. Others also highlight Python’s clean and expressive syntax, extensive developer community, and abundance of third-party libraries used to solve different problems. 

Software as a Service

A wide range of SaaS companies use Python, from small-scale to large-scale ones, and use its different features to their advantage. Most of the following companies chose Python due to its scalability feature, which allowed them to manage the rapid growth of their businesses. 


Screenshot from

I’ll bet my phone on the fact that you keep all your stuff, from photos and videos to files and docs on Dropbox. The company rapidly developed from 2000 users to 200 million, and Python ensured a smooth scaling. 

In fact, the company managed to hire the man who created Python, Guido van Rossum who worked at Google before. He transitioned to Dropbox and made sure they had the most efficient stack in the whole industry.

SurveyMonkey processes nearly 1 million survey responses every day. At first, it was written with C# but later rewritten in Python. The reason to turn to Python was its simplicity, wide range of libraries that allowed building a web app much faster. Additionally, it made it easier to work with deployment, set unit testing, and so on. Not talking about developers who preferred Python to other languages, which was crucial in recruiting new specialists.

Who doesn’t know Mozilla Firefox, right? Well, a lot of people don’t know that Python is related to the success of this browser. 

At first, developers built Mozilla Firefox on PHP+CakePHP. However, as the company developed, those languages couldn’t handle millions of searches on a monthly basis. So, the developers moved Mozilla to Python+Django. More specifically, Mozilla-central has over 35000 Python files with over 230 thousand lines of code. 

Today, the company uses Python for implementing such tasks as building the system, command-line tooling, test harnesses, and CI configuration. Meanwhile, Django is used for Mozilla’s support site and browser add-ons.
