Wanna get started in open source and also score some nice swags? Join the Hacktoberfest® 2020!

In this post, I’ll list 69 beginner-friendly project that you can contribute to. By beginner-friendly I don’t mean simple. Some of them are very complex. However, like any other software project, there’s always some low hanging fruit.

The projects in this list have their issues triaged. That means the maintainers tag the simplest ones as “good first issue”, or "easy". Not only that, most of them ensure that only a novice must submit the pull request. That’s amazing, isn’t it?

By joining the Hacktoberfest, you can contribute with 4 pull requests during October 1 and October 31 and have a change to win a prize. The first 70,000 participants who conclude the challenge will be qualified to pick a limited edition T-shirt or plant a tree. However, be kind and only contribute if you have a value to offer back. Many people are only interested in the swags and that's kind of selfish in my opinion.

Without further ado, let’s check what we’ve got. I’ll break down the list by programming language. This way you can filter the projects by your favorite language.

I'm aware that I haven't covered all programming languages. However, you can also find a list of projects that tags #hacktoberfest here .
