• Mutuals — people you follow who also follow you
• Following — everyone you follow
• Followers — everyone who follows you
• Profile Overview — top languages, total stars, repositories
• Sort users by name (A→Z, Z→A)
• Search and filter within each tab
• Share profile link with one click
• Keyboard shortcut (/) to focus search
• Loading progress with skeleton animation
• Optional GitHub token for higher rate limits
• Dark/Light theme
• 17 languages supported (i18n with RTL)
• PWA — installable as a standalone app
• Fully client-side — no data stored on any server
• SEO optimized with structured data (JSON-LD)

# Install dependencies
npm install
# Run development server
npm run dev

Open http://localhost:3000 in your browser.

Without a token, the GitHub API allows 60 requests per hour. With a personal access token, you get 5,000 requests per hour.

To create a token:

1. Go to GitHub Settings → Developer settings → Personal access tokens
2. Generate a new token (classic) — no scopes needed for public data
3. Paste it in the token field in the app
