Tauri fundamentally rethinks how desktop applications should be built. Instead of shipping an entire Chromium browser with every app like Electron does, Tauri uses the operating system's built-in WebView (WebView2 on Windows, WKWebView on macOS, WebKitGTK on Linux). This architectural decision results in dramatically smaller binaries—a typical Tauri app compiles to under 10MB compared to Electron's 150MB+ starting point—while consuming significantly less memory and CPU at runtime.
The framework bridges your web frontend with a Rust backend through a type-safe command system. You write your UI with whatever frontend framework you prefer, then define Rust functions that handle file system access, networking, cryptography, or any system-level operation. Tauri's security model requires explicit permission grants for each capability, preventing the broad system access that makes Electron apps frequent targets. The IPC bridge between frontend and backend is designed to be both performant and secure by default.
With over 70,000 GitHub stars and backed by the CrabNebula company, Tauri has reached production maturity. Version 2.0 added mobile support for iOS and Android alongside desktop platforms, plugin system for extending functionality, and deep system tray integration. The ecosystem includes official plugins for file dialogs, notifications, auto-updates, deep linking, and more. Companies like 1Password, Cody AI, and Spacedrive have adopted Tauri for production desktop applications.
