description Tauri Overview

Tauri is gaining massive traction as a modern, secure alternative to Electron, particularly for desktop applications. It uses Rust for the backend and system integration, bundling only the necessary web view components, resulting in significantly smaller binary sizes and lower memory footprints. While its mobile support is less mature than Flutter/RN, its focus on secure, lightweight desktop apps makes it a powerhouse for desktop-first cross-platform needs.

help Tauri FAQ

Why are Tauri applications usually smaller than Electron applications?

Tauri uses the operating system's existing webview instead of packaging a complete Chromium runtime with every application. Its core and native command layer are written in Rust, although the interface can still use React, Vue, Svelte, or plain web technologies.

Which webview does Tauri use on Windows and macOS?

On Windows, Tauri uses Microsoft WebView2; on macOS, it uses WKWebView. Because those engines differ, developers must test rendering and web APIs on each target platform rather than assuming Chromium-identical behavior.

Can JavaScript call Rust code in a Tauri desktop app?

Yes. Developers expose selected Rust commands and invoke them from the frontend through Tauri's inter-process communication layer, with permissions controlling access to native capabilities.

Is Tauri 2 limited to desktop applications?

No. Tauri 2 expanded the framework's scope to include mobile targets alongside Windows, macOS, and Linux, although platform-specific plugins and testing are still required.
