Subscribe to my newsletter and never miss my upcoming articles

Hey everyone, HacktoberFest is around the corner (just 15 days away) and for all those who are searching for repositories to contribute to this October, worry not, I have gathered a list of repositories best suited for beginners in open source.


What is HacktoberFest?

Hacktoberfest 2021 will be a month-long virtual festival event to celebrate open source contributions. It is the easiest way to get into open source!

During the entire month of October 2021, all you have to do is contribute to any open-source projects and open at least 4 pull requests. Yes, any project and any kind of contribution. You donโ€™t need to be an expert in programming or coding. It can be a bug fix, improvement, or even a documentation change (I don't recommend it, explore where you can do code changes if there are not many)! And win an awesome T-shirt and awesome stickers.

The Hacktoberfestโ€™s simple plain objective is:

Support open source and earn a limited-edition T-shirt!

But, itโ€™s not just about the t-shirts or stickers. It's about supporting open source. It's about celebrating open source and giving it back. If youโ€™ve never contributed to open source before, this is the perfect time to get started because Hacktoberfest provides a large list of available contribution opportunities (and yes, there are always plenty for beginners too).
