Tauri — Smaller, Faster, More Secure Desktop Apps in Rust

Tauri lets you build smaller, faster, and more secure desktop and mobile applications with any web frontend. Rust backend + OS native WebView (no bundled Chromium) produces ~3MB binaries compared to Electron 150MB.

Quick Use

Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

Prereqs: Rust toolchain (via rustup), Node.js.

# Create project
npm create tauri-app@latest
# Pick frontend: Vanilla/React/Vue/Svelte/Solid
cd my-app
npm install
npm run tauri dev

Call Rust from frontend:

// src-tauri/src/main.rs
#[tauri::command]
fn greet(name: &str) -> String {
  format!("Hello, {}!", name)
}

fn main() {
  tauri::Builder::default()
    .invoke_handler(tauri::generate_handler![greet])
    .run(tauri::generate_context!())
    .expect("error while running tauri app");
}
import { invoke } from "@tauri-apps/api/core";
const msg = await invoke<string>("greet", { name: "William" });
Intro

Tauri is a toolkit for building smaller, faster, and more secure desktop and mobile applications with a web frontend. Instead of bundling Chromium (like Electron), Tauri uses the the OS native WebView (WebKit on macOS/Linux, WebView2 on Windows) and a Rust backend.

What Tauri Does

  • Rust backend — filesystem, shell, network, native APIs
  • Commands — TypeScript → Rust function calls
  • System tray — cross-platform tray icons
  • Menus — native menu bar, context menus
  • Updater — cryptographically signed auto-updates
  • Sidecar binaries — ship extra executables
  • Mobile (v2) — iOS and Android targets
  • Permissions — granular allowlist per capability

Architecture

One process split into Core (Rust) + WebView (HTML/JS). Frontend calls Rust commands via IPC. Tauri v2 introduces a plugin system, mobile support, and fine-grained capability-based permissions (replacing the v1 allowlist).

Self-Hosting

npm run tauri build
# Produces platform-specific installers in src-tauri/target/release/bundle/
# .msi / .dmg / .app / .deb / .rpm / .AppImage

Key Features

  • 3-10MB binaries (vs Electron 150MB)
  • Rust backend (memory-safe, fast)
  • Mobile support (iOS/Android)
  • Capability-based security
  • Code signing (Windows + macOS)
  • Cross-platform installers
  • Plugin ecosystem
  • ~80MB idle memory

Comparison

Framework Size Language Mobile Runtime
Tauri 3-10MB Rust + JS Yes (v2) OS WebView
Electron ~150MB JS No Chromium + Node
Wails ~8MB Go + JS No OS WebView
Neutralino ~2MB C++ + JS No OS WebView

常见问题 FAQ

Q: WebView 不一致怎么办？ A: macOS Safari vs Windows Edge vs Linux WebKitGTK 渲染差异。测试要覆盖所有目标。Tauri 2 正在改进一致性。

Q: 必须学 Rust 吗？ A: 基础命令不需要。只有定制原生功能时才写 Rust。大部分 web 开发者几天能上手。

Q: v1 和 v2 区别？ A: v2 有移动端支持、新 permission 系统、plugin 架构。v1 只支持桌面。
