## TL;DR

Tauri (2019) is an Electron alternative: build desktop apps with web frontend + Rust backend. Uses OS native WebView (Edge/WebKit) instead of bundling Chromium — dramatically smaller bundles (<10MB). Tauri 2.0 (2024) added mobile support (iOS/Android), plugin system, and enhanced IPC.

## Core Explanation

Rust backend: system access, file I/O, shell commands — handled in Rust, exposed to web frontend via `invoke()`. Security: strict CSP, no Node.js in webview, fine-grained permissions (Tauri 2.0 capability system). Bundle sizes: 3-10MB vs. Electron's 100MB+. Mobile: Tauri 2.0 supports Android (via WebView) and iOS (via WKWebView).
