Tauri

• Core Process: Manages windows, system tray, IPC routing, and has full OS access
• WebView Process: Renders UI using system WebViews (no bundled browser!)
• Principle of Least Privilege: Each process has minimal required permissions

Inter-Process Communication (IPC)

Two IPC primitives:

• Events: Fire-and-forget, one-way messages (both Core ??WebView and WebView ??Core)
• Commands: Request-response pattern using invoke() API (WebView ??Core only)

Why Tauri?

• Small binaries: Uses OS WebViews (Microsoft Edge WebView2/WKWebView/webkitgtk)
• Security-first: Message passing architecture prevents direct function access
• Multi-platform: Desktop (Windows/macOS/Linux) + Mobile (Android/iOS)

Quick Reference
