Our goal is simple but ambitious: to make deep-diving into code feel more like an adventure! Most of us know that Open Source is the backbone of the modern web, but finding the right project to learn from or contribute to can feel like searching for a needle in a digital haystack. Not anymore. We turn complex code repositories into interactive, AI-guided learning journeys. Choose how you learn best: Deep-dive, Socratic, Feynman, or traditional book format. No more 'wall of information' fatigue.
Most of us know that Open Source is the backbone of the modern web, but finding the right project to learn from, contribute to, or integrate can feel like searching for a needle in a digital haystack.
We built os.ninja because we wanted to stop "searching" and start "discovering." We wanted a way to navigate the massive ecosystem of OSS with the speed and precision of a ninja.
Our goal is to lower the barrier to entry for high-level software mastery. Open source shouldn't be intimidating—it should be your playground. By heading to os.ninja, you’re getting a curated, high-signal view of the open-source world with learning paths for hundreds of open source repos.
I’d love to hear your thoughts: What is the biggest challenge you face when trying to learn a new open-source stack? Do you have any suggestions to make the product more useful. Projects like Google CodeWiki and Devin's Deep Wiki throw out a lot of information but that's not how learning happens. Information is not education. We’re building os.ninja on the belief that learning requires a hook, not just a handbook.
I'll be here all day to answer questions and chat about the future of OSS learning and discovery! What's your #1 struggle with new projects? We're all ears for suggestions.
Wow! Interesting idea. It could work well for junior developers, but it would also be very useful for experienced developers who work with legacy code.
Can I save specific insights or code snippets from my journey into a personal knowledge base within the app?
This looks very cool. I really like that feature which allows users to toggle between standard/Feynman/Socratic for each material. Is it possible to add a global setting somewhere?
@puneet_singh25 Congrats on the launch! 'Automating operations' is the exact problem space I work in every day with my clients. The UI looks super clean compared to legacy ERPs.
How do you handle custom integrations with obscure tools? Do you have a webhook/API layer where I could connect something like n8n for more complex workflows?
Upvoted! 🚀
it seems currently I can only learn only limited repos. for new repo i have to request. when can we search the repo i am really interested? I think different people have different interest
Helping people understand complex things without intimidation is hard to get right. What part of open source did users struggle with the most before you built this?
When a developer is choosing between generic LLM chat, repo-wiki generators, and traditional docs/READMEs, what is the clearest point where OS Ninja wins—and what makes you confident users will switch rather than treat this as a one-time novelty?
This is really cool! Will you consider generating some video tutorials, similar to notebookLM?
switching between Socratic and Feynman modes is such a smart unlock for docs fatigue. does the AI keep my context if I swap modes mid-stream?
Looks really cool! As a designer/coder I've wanted to understand tailwindcss a bit better to structure my design files and tokens to match, and this looks like a great way to learn that. I just submitted a request for the repo to be added!
Pretty cool! How do you keep the learning content in sync with fast-changing repos?
Open Source Democratises Innovation, and I'm excited to see this project come to life. Congrats, Puneet!
