## 🎯 RECOMMENDATION FOR TRACERTM

### HYBRID APPROACH (Recommended)

**Phase 1: CLI + Web**
- Python CLI (Typer + Rich)
- React 19 web (Vite)
- PostgreSQL backend (Go)

**Phase 2: Add Desktop**
- **Primary**: Tauri (lightweight, fast, secure)
- **Alternative**: Electron (if need React code reuse)

**Phase 3: Optional Native**
- macOS: Native Swift app
- Windows: Native C# WinUI
- Linux: GTK native

---

## 🚀 RECOMMENDED STACK

```
CLI:      Python 3.12 + Typer + Rich
Web:      React 19 + Vite + Zustand
Desktop:  Tauri + React (or Electron)
Backend:  Go + Echo + GORM
Database: Supabase (PostgreSQL + pgvector)
Search:   pgvector + pgfts (no Meilisearch)
```

**Why Tauri for Desktop?**
- ✅ Tiny bundle (3-8MB vs 150MB)
- ✅ Fast startup (500ms vs 2-3s)
- ✅ Low memory (50-100MB vs 300-500MB)
- ✅ Can wrap React web app
- ✅ Native OS integration
- ✅ Security-first design
