Contributing to top open source projects is a great way to build your programming career. Not only can you practice software development, but you can put your open-source code projects in your portfolio. Many employers look for an active, thriving Github account.
Still, the open source projects list is virtually infinite. If you don’t want to comb through an endless list of open source projects, check out our list instead.
Today, we’ll look at some of the best open source projects to contribute to. Some of these open source code projects are high-profile and popular—while others are just cool open source projects you can use to get some practice.
Before we narrow down the ideal top open source project for contributors, let’s define an open source project. An open source project has source code available for anyone to view, download, fork, and modify. The MIT license is the most common type of license for these projects.
You can make as many changes as you like to an open source project — and you don’t even need to ask permission from the project maintainer. Additionally, you can contribute your code changes back to the original project.
Let’s look at some of the top open source projects you can contribute to.
The best open source project will have an active community and user base. Moreover, the best open source projects for your portfolio relate directly to what you want to do in your programming career.
If you’re a beginner programmer, contributing to open source projects is a great way to get experience. You can get some practice with coding and software development. If you’re an experienced programmer, contributing to open source projects is a great way to give back to the community.
No matter your skill level, contributing to open source projects has many benefits like:
- Building your portfolio
- Gaining experience
- Improving problem-solving skills
- Networking with other developers
- Getting recognition for your code
Of course, you don’t need to contribute to an open source project to get these benefits. You can also fork a project and build your own version of it.
If you want to contribute to an open source project, the first step is finding a project you’re interested in. Let’s look at some of the best open source projects in different programming languages.
So, let’s look at some of the most popular open source projects by language.
In Python, most open source projects relate to artificial intelligence, machine learning, and neural nets. But there are also some classic web development frameworks and statistics and data analysis suites.
Get into machine learning with this neural network library. Developed in Python, TensorFlow is an open source deep learning framework. While it’s definitely not for beginners, it’s a great project to show off your skills. Start developing neural nets in Python, and you can write your ticket to virtually any form of development.
If you love data visualization and analysis, Matplotbib is where you want to be. Matplotlib is one of the world’s most popular data visualization technologies — and it’s an extremely active GitHub community.
A web development library in Python, Flask is perfect for those interested in developing and programming for the web. If you’ve already used Flask as a web developer, why not try to fix a few bugs and develop your GitHub account?
Django is another incredibly active web framework project. Fostering high-level, rapid deployment, Django is a free, open-source solution maintained by the Django Software Foundation. Many new web developers start by learning Django.
PyTorch is another high-level Python package dealing with neural nets and machine learning. Invest some time into PyTorch if you want to learn more about artificial intelligence and Python simultaneously. You can tackle a few bug fixes to get started.
React and React Native are component-based frameworks for developing dynamic, easily deployed UIs. Developed by Facebook for the rapid deployment of complex web properties, React is great for both mobile and web developers.
Google developers developed Polymer — an open source library for developing websites using web components. If you want to jump into a FANG project, make it Polymer or React. You’ll develop your understanding of component-based libraries while expanding your portfolio.
You’ll find an extraordinarily wide breadth of open source projects in C++. You can develop anything from an operating system to a game development kit.
Serenity is a fun little operating system project, replicating a graphical Unix-like operating system with new technologies. SerenityOS is a fully featured operating system initially released in 2018.
Get serious about your development with MongoDB. MongoDB is an open-source, cross-platform database for documents. A NoSQL database solution, MongoDB is frequently used by developers for data mining.
Improve your code quality and security with SonarSource. SonarSource provides a suite of products designed to improve continuous integration and development through static code analysis and quality checks.
14. OBS Studio
OBS Studio is one of the most popular streaming platforms today. It’s used for streaming live on platforms like Twitch and YouTube. You can learn about live streaming services and video capture.
Like C++ projects, Java open source projects are extremely diverse. From Arduino controllers to database technologies, you can find a Java open source project for practically any task.
A mocking framework for Java. Mockito runs unit tests and automated testing processes. Written in Java, Mockito testing is available for languages such as Kotlin and Scala. Developers can learn more about unit testing and QA.
An automation server with extraordinary popularity and adoption, Jenkins is an excellent project to dig into and explore. It’s ideal to further explore automation and its advantages.
Many of Google’s projects are open source — including Guava. Take a look at how Google developers start and maintain a project by looking at Google’s common Java libraries.
What makes the above projects the best open source projects to contribute to? A good open source project should be:
- About something you’re interested in
- Written in a language that you know (or want to learn)
- Supported by a large, active community
- A technology that you want to learn
If an open source project meets that criteria, feel free to jump in. Don’t be afraid to make mistakes. Sometimes, you learn more from making a mistake than from a successful commit.
It’s time to start developing your own open source projects. Explore the projects above — or, if you don’t feel ready, consider taking a bootcamp or class. You can even explore the code of a web development IDE.
An open source project is a project where the source code is publicly available. Anyone can view, edit, and contribute to the code. Working on an open source project lets you jump into an existing project, learn how it works, and help the community grow.
There are many good open source projects. Ideally, you’ll work on a project that aligns with your interests. If you’re interested in Python and machine learning, for example, you might want to work on Pytorch. If you’re interested in Java and database management, consider Realm.
There are many ways to monetize open source projects. For example, you can create a premium version of the project, or you can offer consulting services. Most directly, if you work on open-source projects, you can add your work to your Github profile and potentially build your career.
Open source projects are important because they allow people to collaborate, share code, and learn from each other. On an individual level, open source projects help you learn and grow as a developer.
