📈 Scaling

Current Setup (Development):

Single server
Docker Compose
Good for: 10-50 users

Production Scaling:

Horizontal scaling (stateless backend)
Load balancer for multiple instances
Managed PostgreSQL (RDS, Cloud SQL)
Redis for session storage
CDN for frontend assets

Cost Estimates:

Small team (10 users): ~$120/month
Medium team (50 users): ~$500/month
Enterprise (500 users): ~$5,000/month

Frontend: ESLint, Prettier, TypeScript

📝 Configuration

Backend (.env)

ANTHROPIC_API_KEY=sk-ant-...     # Required
DATABASE_URL=postgresql://...     # Auto-configured
SECRET_KEY=...                    # Auto-generated

Frontend (.env.local)

NEXT_PUBLIC_API_URL=http://localhost:8000
NEXT_PUBLIC_WS_URL=http://localhost:8000

🐛 Troubleshooting

Backend won't start

docker-compose logs backend
# Check for missing ANTHROPIC_API_KEY

Frontend won't connect

# Verify backend is running
curl http://localhost:8000/api/health

# Check .env.local exists in frontend/

WebSocket not connecting

Ensure backend is running
Check browser console for errors
Verify NEXT_PUBLIC_WS_URL is correct
