For a while, I've been looking for a comprehensive, free, and interactive platform to practice Go, especially specific concepts like concurrency, interfaces, and goroutines, with immediate feedback. Since I couldn't find exactly what I needed, I decided to build one myself: an open-source GitHub repo with 30 Go challenges.

The goal is to provide a structured way to learn Go by doing. Each challenge comes with learning materials and automated tests. Users can run their code directly in a web interface, get instant test results, and even track performance. There's also a leaderboard for some friendly competition.

I've tried to make it easy to jump in without much setup. You can simply fork the repo, solve challenges, and even get your solutions auto-judged via GitHub Actions if you push them.

It's still evolving, and I'd love to get feedback from the HN community. What challenges would you like to see added? Any thoughts on the testing or documentation?

Thanks for checking it out!
