Overview — all stats at once

npx repochart vercel/next.js --overview

Fetches stars, commits, contributors, and languages in parallel and renders all four charts sequentially in your terminal.

Authentication

RepoChart uses the GitHub CLI (gh) for all API calls — no tokens to manage. Just run gh auth login once and you're set. Authenticated requests get 5,000 req/hour vs 60 for unauthenticated.
