Your GitHub profile as a 3D pixel art building in an interactive city.
Git City transforms every GitHub profile into a unique pixel art building. The more you contribute, the taller your building grows. Explore an interactive 3D city, fly between buildings, and discover developers from around the world.
- 3D Pixel Art Buildings — Each GitHub user becomes a building with height based on contributions, width based on repos, and lit windows representing activity
- Free Flight Mode — Fly through the city with smooth camera controls, visit any building, and explore the skyline
- Profile Pages — Dedicated pages for each developer with stats, achievements, and top repositories
- Achievement System — Unlock achievements based on contributions, stars, repos, referrals, and more
- Building Customization — Claim your building and customize it with items from the shop (crowns, auras, roof effects, face decorations)
- Social Features — Send kudos, gift items to other developers, refer friends, and see a live activity feed
- Compare Mode — Put two developers side by side and compare their buildings and stats
- Share Cards — Download shareable image cards of your profile in landscape or stories format
| Metric | Affects | Example |
|---|---|---|
| Contributions | Building height | 1,000 commits → taller building |
| Public repos | Building width | More repos → wider base |
| Stars | Window brightness | More stars → more lit windows |
| Activity | Window pattern | Recent activity → distinct glow pattern |
Buildings are rendered with instanced meshes and a LOD (Level of Detail) system for performance. Close buildings show full detail with animated windows; distant buildings use simplified geometry.

# Clone the repo
git clone https://github.com/srizzon/git-city.git
cd git-city
# Install dependencies
npm install
# Set up environment variables
# Linux / macOS
cp .env.example .env.local
# Windows (Command Prompt)
copy .env.example .env.local
# Windows (PowerShell)
Copy-Item .env.example .env.local
# Fill in your environment variables
# Run the dev server
npm run devOpen http://localhost:3001 to see the city.
After copying .env.example to .env.local, fill in these values:
NEXT_PUBLIC_SUPABASE_URL,NEXT_PUBLIC_SUPABASE_ANON_KEY,SUPABASE_SERVICE_ROLE_KEYGITHUB_TOKENADMIN_GITHUB_LOGINSif you want access to/admin/ads
Open your Supabase project dashboard, then go to Project Settings -> API.
NEXT_PUBLIC_SUPABASE_URL: your project URLNEXT_PUBLIC_SUPABASE_ANON_KEY: the public anon keySUPABASE_SERVICE_ROLE_KEY: the service role key for server-side admin access
For local GitHub login to work, you also need to configure the GitHub OAuth provider in Supabase and add your local callback URL if required by your setup.
Open GitHub and go to Settings -> Developer settings -> Personal access tokens.
- Fine-grained tokens are recommended if you only want to grant the minimum repository/profile access this app needs.
- Classic tokens also work if that fits your setup better.
Create a token, copy it once, and place it in GITHUB_TOKEN inside .env.local.
AGPL-3.0 — You can use and modify Git City, but any public deployment must share the source code.
