I built a CLI to see my real GitHub language stats – does something like this already exist?

#github #language #stats #privaterepositories

I recently created my new online CV and wanted to show all of my contributions — also the ones from private repositories. My GitHub profile looked nearly empty, even though I'd been coding professionally for years. Most of that work just happened to live in private repos.

That's when I realized: GitHub's profile is basically useless for showing your real activity as a professional developer. So I started looking for a tool that could compute honest, per-language stats from all my commits — public and private. I couldn't find one. So I built it: github-lang-stats.

What it does

It scans every commit you've personally authored on GitHub — including private repos — and calculates how many lines you've changed per programming language. The result is an honest, verifiable snapshot of your actual work.

npx github-lang-stats --token=<your-github-pat>

That's it. No install needed. Just a GitHub Personal Access Token.

Why not just use the GitHub profile?

No language breakdown — GitHub shows total contributions, not which languages you used
Private repos are invisible — Most (of my) professional work happens in private repos, which don't show up at all
