Server listens on `http://localhost:8080`. See [API Reference](./doc/api.md) for endpoints.
## Web UI
The chess server includes an embedded web UI for playing games through a browser.
### Enabling Web UI
```bash
# Start with web UI on default port 9090
./chessd -serve
# Custom web UI port
./chessd -serve -web-port 3000 -web-host 0.0.0.0
# Full example with all features
./chessd -dev -serve -web-port 9090 -api-port 8080 -storage-path chess.db
```
### Features
- Visual chess board with drag-and-drop moves
- Human vs Computer gameplay
- Configurable engine strength (0-20)
- Move history with algebraic notation
- FEN display and custom starting positions
- Real-time server health monitoring
- Responsive design for mobile devices
Access the UI at `http://localhost:9090` when server is running with `-serve` flag.
## Documentation
- [API Reference](./doc/api.md) - Endpoint specifications
