18 Popular Websites Built with Python

Python’s popularity, in and of itself, is proof that it is well worth adding to your development toolkit. On the other hand, which major tech giants employ Python for web development? Let’s have a look at the top 18 well-known websites that were built with Python.

1. Netflix

Netflix is the world’s most popular internet television network, with over 33 million subscribers in 40 countries watching over one billion hours of TV shows and movies each month, including Netflix’s original series.

Netflix developers use Python because of its comprehensive standard library, short and clear yet expressive syntax, big developer community, and abundance of third-party libraries.

Netflix is the perfect example of a firm that has kept up with technological advancements. Netflix used to rent DVDs by mail, but it swiftly hopped on the digital bandwagon and grew to become one of the world’s most popular streaming services.

2. Google

Google is the most extensively used search engine on the planet. It is another primary Python-based website. Developers can switch traffic and manage search requirements for each level using the language and its supporting infrastructure.

Using Python, Google is a web application that operates smoothly and without errors during development. Python is now an official language at Google, with many applications ranging from system development and administration to code evaluation.

Python is also utilized in many of Google’s cutting-edge machine learning and AI projects, which is becoming increasingly crucial in big tech as the need for data analytics grows.

3. YouTube

YouTube, a Google subsidiary, was built primarily in Python. The world’s largest video streaming site, which has been distracting us from existential sorrow with funny videos since 2005, is a prime real-world example of Python in web development.

Python powers the site in various ways, including view video, administrator video, data access, and website control templates, to name a few. It has various features and libraries that make the user experience more dynamic.

It has been designed to make the process of uploading, downloading, and sharing videos as simple as possible. Surprisingly, it didn’t start that way. The initial codebase for YouTube was PHP. However, after a few months, the creators decided to switch to Python because of the latter’s superior speed, performance, and flexibility.

4. Instagram

The backend of Instagram, the world’s most popular online photo-sharing program, is written in Python. Instagram presently has the world’s largest Django web framework deployment, fully built-in Python.

It’s user-friendly, straightforward, tidy, and logical. Instagram’s user interface is made possible through Python web programming. It’s also great for building a team of developers because the platform’s scalability isn’t an issue.

Python is used to create APIs, search mechanisms, and other features. That’s something I’m sure you didn’t know!

5. Uber

Python was used to create the ride-hailing service, making about 15 million journeys every day. Python, Node.js, Go, and Java is their major tech stack. Python frameworks such as Django and Flask are also widely utilized to create various features of Uber.

While Python isn’t Uber’s only programming language (it makes up approximately 35% of their tech stack), it is the backbone of its back-end operations. This includes data analytics features for forecasting supply and demand, user surges, and arrival times—all of which are highly mathematical operations that Python excels at.

6. Pinterest

Pinterest, a virtual pinboard and social bookmarking platform has been on our screens for over a decade. Users can create image collections for everything from dogs to wedding gowns to origami art. Python was chosen as the company’s first programming language because it allowed them to scale and construct reliable apps.

The organization uses a variety of third-party Python modules for communication and configuration management. The site’s persistent dependence on machine learning, on the other hand, strongly suggests that Python is still a key component of its software stack.

7. Dropbox

Dropbox is a place where you can save all your images, documents, videos, and data. Also, one of the world’s foremost providers of cloud storage solutions, Dropbox, employs Python web programming in its tech stack.

It uses the programming language to host files and lets users interface with various application components in real-time. It is still at the forefront of the industry today, and Python is responsible for most of its success.

Dropbox has used Python on both the server and client sides since its inception. Dropbox chose the language because of its cross-platform capabilities and readability, allowing them to implement, test quickly, and deploy new product features.

The organization is so committed to Python that it hired Guido van Rossum, the language developer, from 2012 to 2019.

8. Quora

Quora is probably the most well-known Q&A site on the internet, and it’s best recognized for its intriguing questions and occasionally dubious solutions. It is another site that heavily relies on Python.

Because Quora is such a dynamic site, Python has allowed them to construct and test new functionality with fewer lines of code, allowing them to speed up the creation of new features.

Quora’s backend uses a variety of Python packages, including Tornado and PyPy, among others. The codebase has changed dramatically in the last five years. Today, the Python application serves as a foundation for Quora’s whole development.

9. Spotify

Spotify allows you to listen to select music or albums right away, with almost no buffering. Since its inception in 2008, the app has grown to over 75 million paid customers, and employs Python significantly in its software. Python’s simplicity and readability were required because the company wanted to focus on speed. The organization uses Python async frameworks for IO-bound services. Spotify’s web backbone, which consists of multiple interconnected services, heavily relies on Python. Around 80% of these, according to the business, are written in Python. Luigi, a Spotify-developed data analytics tool, which drives Spotify’s Radio and Discovers features and recommendations, was built to swiftly prototype complex data processes. Luigi is also written in Python.

10. Reddit

Reddit is a social news aggregation platform usually referred to as the internet’s front page. The server-side of Reddit is written in Python. The company admires the programming language because of its vast libraries. Even new developers may get started coding on the project because the code is exceptionally expressive, understandable, and straight. When every time you send a request to Reddit via your browser, the webserver utilizes Python to translate it. The relevant HTML is subsequently sent back, which you see in your browser. You can think of Python as the link between your server request and what appears on your screen in this situation.

11. Facebook (Meta)

Facebook (now renamed Meta), the world’s most popular social networking site, has kept us connected to our friends and stalking exes since 2004. Unless you’ve been living under a rock, you’re aware that the site is involved in various activities, from messaging to live-streaming. As a result, its products and services are available in multiple languages. On the other hand, Python plays a significant role, accounting for at least 21% of their codebase.

12. Amazon

Amazon also uses Python. Thanks to Amazon, we can get almost anything delivered to our doorsteps at the touch of a button, and we don’t have to worry about how it gets there. Amazon employees, in particular, have created Python machine learning algorithms that work with the company’s Hadoop data storage system.
