In-Depth Analysis

Tauri for Desktop Focus

Tauri excels at desktop applications with native performance. The Rust backend provides system tray, multiple windows, global shortcuts, and automatic updates. Bundle size stays under 15MB. Companies like Craigslist and Discord use Tauri for desktop apps where users expect small downloads and fast startup.

Capacitor for Mobile Focus

Capacitor dominates mobile app development with Ionic. The framework provides access to all native device features through plugins. Many production apps use Capacitor for cross-platform mobile. The JavaScript-only approach makes it accessible to frontend developers without native training.

When to Use Both

Some companies build desktop apps with Tauri and mobile apps with Capacitor sharing the same web frontend code. This approach maximizes platform strengths while maintaining code reuse. The backend differs (Rust vs JavaScript plugins) but UI components stay identical across desktop and mobile.
