Open-source software is a type of software where the original source code of the software is made available freely and is published under a license so that users can download, modify and customize it according to their requirements or for research. Today open source is not only used by individuals but most multinational companies and organizations like Google, Facebook, Microsoft, Netflix, etc. are heavily dependent on free and open-source software. Contributing to open source not only helps you sharpen your skills but also helps you develop a great hands-on experience with real-world problems while maintaining a great portfolio!


Contributing to open source seems daunting to beginners at first. According to a survey, close to 60% of newcomers do not know where to start from and more than 10% feel it is overwhelming at first. This may seem difficult initially since anyone can get confused after looking at a huge code base of open-source software or the open issues may not make sense to you. The best way to get started is to find issues that have a “newcomers”, “good first issue” or “easy” label. These issues are comparatively easy and therefore could serve to be a good starting point. Also, you can choose repositories that are beginner-friendly. Therefore, we will be discussing the top 7 open-source projects, especially for beginners so that you can get started!
