10 GitHub Repositories every Developer should know

Other than being the home for some of the most interesting Open Source Projects on the internet, GitHub is also a great place for sharing resources of all kinds, from free books to APIs, from roadmaps to project ideas and to the projects.
But with sheer mass it becomes difficult to find the most useful repositories which you may think doesn't exists.
So I have curated this list of ten fabulous repositories that provide a great value for all web and software developers.

All of them will add value to you and help you to become a better web or software developer or both.

1. Free Programming Books

GitHub🌟: 183K+

Offered in a variety of different languages Free Programming Books is no doubt one of the most popular and starred repositories on GitHub. Even though it has "Books" in its name, it offers a lot more than that. It contains sections of free online courses, interactive programming resources, problem sets and competitive programming, programming playgrounds and podcasts and cheat sheets for almost every programming language.

But has a major collection of programming books which makes it an "Awesome" collection.

2. Developer Roadmap

3. OSSU Computer Science


If you don't have a computer science background or degree and want the equivalent knowledge same as a Computer Science degree then this repository is for you. It's for those who want a proper, well-rounded grounding in concepts fundamental to all computing disciplines. It offers all the resources to help you become a self-taught computer science graduate equivalent and has a worldwide community of learners.

It is designed according to the degree requirements of undergraduate computer science majors, minus general education (non-CS) requirements, as it is assumed most of the people following this curriculum are already educated outside the field of CS. The courses themselves are among the very best in the world, often coming from Harvard, Princeton, MIT, etc., but specifically chosen to meet the following criteria.

4. Awesome

GitHub🌟: 158K+

As the name describes it has an Awesome lists of all kinds of interesting topics ranging from computer science to media, from gaming to business and the list goes on.

It offers advice on how to study to become a reliability engineer or operations engineer. It also has links to the flashcards for quickly brushing up your knowledge and stay updated originally created by the author of the repository who landed a job at Amazon. And there are much more success stories like that.

Because system design often is a required component of the technical interview process at many companies, this repository can also help you to prepare for those interviews with a study guide, advice on how to approach an interview, interview questions with solutions, Anki flashcard sets for interactive learning, and interactive coding challenges.

10. Design Resources for Developers

Awesome Repos

Awesome Repos is just a few weeks old but the way it's including all the fantastic repositories on GitHub is mindblowing. It has a number of resourceful repositories packed in just one place. All you have to do is just visit this repository that's it. The repository is still growing and welcomes PRs.

I hope you find these repositories as useful as I do and can use them to become better software engineers. Thanks for reading!

I find it hard to find cool repos that aren't beginner skewed. I think it's the nature of beginners coming and going liking things like this then not continuing. While, existing devs are smaller pool so less likes for repos that are for more intermediate devs.
