Onboardly – Ask questions about any GitHub codebase in plain English

A few months ago, I asked HN about the biggest pain points when joining a new team (https://news.ycombinator.com/item?id=47368472). Most people said it was the tribal knowledge buried in the code.

I've spent my time as a student building Onboardly to solve this. It’s a web app that indexes your GitHub repo and lets you ask questions in plain English. Unlike a general LLM, it cites the exact files it’s looking at so you can verify the logic.

Tech stack: FastAPI backend, Next.js frontend, and a RAG architecture for the indexing. I’m currently hosting it on Render's free tier, so there might be a slight delay on the first login—I'm working on that!

I’d love for you guys to break it and tell me where the answers feel 'off' or what features a dev actually needs for onboarding.

It's free to try — would love feedback on answer quality across different repo types and languages.
