Turn GitHub repositories into navigable context maps, guides, evidence, and scoped chat. Onboardy helps developers and AI coding agents understand unfamiliar GitHub repos faster. It generates architecture maps, files to read first, evidence-backed guides, ownership clues, scoped chat, and MCP-ready context so you can move through larger codebases and multi-repo projects with less setup time.

Hey Product Hunt, I’m launching Onboardy today.
I built it after realizing I was onboarding my AI coding agent every session: explaining the repo structure, pointing it to important files, reminding it how systems connect, and giving it context before it could do useful work.
Onboardy turns a GitHub repo into a navigable architecture map for humans and AI agents. It highlights key systems, service relationships, files to read first, evidence-backed guides, ownership clues, and MCP-ready context.
The goal is simple: make it easier to understand unfamiliar codebases before making changes, especially in larger repos or multi-repo projects.
Would love feedback from anyone using Cursor, Codex, Claude Code, Copilot, or similar tools.

Love how it pulls the architecture map straight from a repo link. One thing that would help even more is a "compare to last PR" mode, so I can see exactly which files shifted ownership or changed context after a big refactor.

@esmanurbaaj0ue Hi Esmanur, that’s totally valid. I’ve actually been thinking about having the GitHub app trigger on each PR and generate an updated map showing what changed, including affected files and ownership or context shifts. Would you want that while the PR is open for review, or after it merges as a running history?

The MCP context export is a great touch for hooking into agents. One thing that would really help me is the ability to compare two repos side by side, especially for spotting shared services or duplicated logic across a monorepo. Would love to see that as a next step.

@yasemin1123082 Hi Yasemin, glad the MCP export stood out. I’ve been thinking about adding workspaces where you could group analyzed repos across different services. From there, Onboardy could map shared dependencies and surface duplicated logic across the whole system. Would a combined system map be more useful, or a side-by-side comparison that calls out the overlaps?

Love how this turns a messy repo into something I can actually navigate, the architecture maps alone would save me hours. One thing I'd love to see is the ability to compare two branches or PRs side by side so I can quickly spot what changed in the architecture or ownership before reviewing.

@erdaljghf Hi Erdal, I agree — I think a change-aware view could be really useful here. I could see the GitHub app generating a before-and-after map whenever a PR is opened or updated, then highlighting architecture and ownership changes before review. Would you want the summary directly in GitHub, or would you open the full comparison in Onboardy
