Tauri Has a Free Desktop App Framework — Build Native Apps with Web Technologies (Not Electron)

Tauri is a framework for building tiny, fast desktop apps using web technologies — 10x smaller than Electron.

What You Get for Free

• Tiny bundles — 600KB vs Electron's 150MB
• Low memory — 30MB vs Electron's 300MB
• System WebView — uses OS native webview (no bundled Chrome)
• Rust backend — secure, fast backend code
• Cross-platform — Windows, macOS, Linux
• Auto-updater — built-in update mechanism
• System tray — native system tray support
• File system — secure file access APIs
• IPC — type-safe communication between frontend and Rust

Quick Start

npm create tauri-app@latest
cd my-app && npm install && npm run tauri dev

// Frontend (React/Vue/Svelte/vanilla)
import { invoke } from '@tauri-apps/api/core'

const result = await invoke('greet', { name: 'World' })

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

Why Developers Switch from Electron

Electron ships an entire Chrome browser with every app:

• 600KB — vs Electron's 150MB minimum bundle
• 30MB RAM — vs Electron's 300MB+ per window
• Rust backend — memory-safe, no Node.js security issues
• System native — uses OS webview, feels native

A team's Electron app was 180MB and used 400MB RAM. After Tauri rewrite: 2MB app, 40MB RAM, same UI. Users stopped complaining about system slowdowns.
