CodeCrafters (YC S22)

CodeCrafters lets you learn in such a practical way that you don't normally see on learning platforms. It's nice to be able to explore concepts and understand how the technologies we use everyday work under the hood, while also learning more about languages themselves.

Solves a much needed problems for intermediate and experienced professionals in tech.

CodeCrafters reminds me of the concept of "consume the original source" that is coming back into startups, science, literature and even among movie watchers. For example: - you'd read the paper/ programming book that came out decades ago and first uttered the words "object oriented design", subsequently standing the test of time over the book that came last year - you'd watch the first film noir and learn more than any recent film based on the concept. - "The act of creation is singular, as is the moment of creation, and the result is something fresh and strange. If you are copying these guys, you aren’t learning from them." - Peter Thiel. The key takeaway from the quote is learning from an original, singular creation. This product has made me question the books I pick up to read, MOOCs or the education I had years ago because they've really not equipped me to be the best programmer. I hope I was younger, I'd put the entirety of CodeCrafters challenges on my to-do list. The design of this product puts one into flow by slowly turning on the complexity and one comes out with mastery of a particular important technology ex. Caches.

There are few sites I like as much that have a step by step guide. The realtime feedback is so good, it's awesome.

Codecrafters is so well done - it the only dev learning platform I was excited to use. Absolutely loved building my own version of redis one morning when I couldn't sleep or trying to build my own version of git. The UX of the product and how it intergrates with your workflow is so well thought out and overall such a positive experience to use

Bravo, @rohitpaulk and @sarupbanskota! CodeCrafters is an absolute game-changer for software engineers. I believe hands-on learning is the best way to truly understand complex tools. CodeCrafters seems like the perfect platform to recreate popular developer tools and dive deep into their code. Are all the courses made in-house or by external experts? How do you prioritize what courses will be launched next?

Congrats on the launch! I have been working through CodeCrafters with my friends during my time at Recurse Center, programming for the joy of programming. Incredibly fun way to learn to build fundamental technologies from scratch. As an engineer, I am always into taking my tools apart, understanding the individual building blocks for what they are, and putting it them back together. CodeCrafters is where I go to put them back together in a guided way that keeps me motivated and enthusiastic. Thank you for making CodeCrafters!

This product is very helpful for beginners like me and the learning experience is fun.

congrats on the launch! codecrafters has been a staple in my coding practice for the last 9 months now. as a vc, i don't get a *ton* of time to write code, but it's really important to me that i keep it up so that i can build & experiment with new technologies. codecrafters provides the perfect, byte-sized (no pun intended) challenges for me to complete so that i'm constantly keeping my skills sharp. when i studied cs in college, i was often frustrated at how theoretical everything felt. i didn't make a website until my senior year. i spent so much time learning data structures & algorithms, without actually learning how to build something real with them. codecrafters is different: it orients around the end-product and gives me a sense of accomplishment for building something real & useful. 11/10 recommend for anyone who wants to learn to code (start with the easy ones), up-level their coding abilities (try implementing a project in a new language), or just keep up their coding abilities with fun challenges. feature request: would love some more challenges that are less infra-y and more product-y. for example, i'd love to build my own cal.com, chatGPT, AI headshot generator, etc.
