Tauri architecture uses a core-shell design that separates a Rust-based backend core from the frontend UI. This separation leverages native webviews for rendering, enabling secure, lightweight desktop applications across Windows, macOS, and Linux.

Tauri structures IPC communication using safe message passing between the frontend and backend. You define IPC commands and events in your Rust backend core, which the webview frontend invokes to execute logic and return data securely.

Tauri uses native webviews provided by the operating system rather than bundling a complete browser engine. This approach significantly reduces bundle size and leverages OS-level security features for your desktop application.

Tauri's security model defines clear trust boundaries between the frontend and backend. It enforces capability and permission models for IPC access and incorporates Content Security Policy (CSP) considerations to prevent unauthorized actions.

Yes, Tauri supports cross-platform deployment across Windows, macOS, and Linux. Its architecture leverages platform-native webviews and a shared Rust backend core, allowing you to build and distribute dependable desktop applications from a single codebase.

Using native webviews in Tauri means your application rendering depends on the specific webview implementation installed on the user's operating system. This can lead to minor UI inconsistencies across platforms and requires testing each OS environment for compatibility.
