| user-invocable | true |
A guide for developing desktop apps using web technologies (HTML, CSS, JavaScript). Support Windows, macOS, and Linux simultaneously with a single codebase.
| Framework | Tier | Recommendation | Use Case |
|---|---|---|---|
| Tauri | Tier 2 | ⭐ Primary | Lightweight (3MB), Rust security |
| Electron | Tier 3 | Supported | Mature ecosystem, VS Code-like apps |
AI-Native Recommendation: Tauri
- 35% YoY growth
- 20-40MB memory vs Electron's 200-400MB
- Mobile support (iOS/Android) via Tauri 2.0
- Rust backend = memory safety
Ecosystem Recommendation: Electron
- Mature tooling
- Node.js integration
- Proven at scale (VS Code, Slack)
Starter → Tauri (v2) [Tier 2]
- Simpler setup than Electron
- Smaller output bundles (~3MB vs ~150MB)
Dynamic → Tauri + auto-update [Tier 2]
- Includes server integration, auto-update
- Lower memory footprint
Enterprise → Tauri [Tier 2] or Electron [Tier 3]
- Tauri for performance and security
- Electron for complex Node.js integration

Things impossible on web but possible on desktop:
- System tray icon
- Global shortcuts
- Native notifications
- Drag and drop (file path access)
- Full clipboard control
- Native menus
Web: Requires Service Worker, limited
Desktop: Works offline by default
⚠️ Server integration features must handle offline!

□ Decide local data storage method (SQLite, JSON file, etc.)
□ Decide if cloud sync is needed
□ Consider platform-specific UI guidelines (macOS, Windows)
□ Plan keyboard shortcuts
□ Design menu structure
□ Support dark/light mode
□ Handle window resizing
□ Handle platform-specific UI differences (window control positions, etc.)
□ Don't expose Node.js APIs directly (use contextBridge)
□ Security handling when loading external URLs
□ Encrypt sensitive data storage
□ Code signing (macOS Notarization, Windows Signing)
□ Set up auto-update
□ App Store submission (if needed)
