Best Desktop App Frameworks in 2026: Electron vs Tauri vs Neutralino

TL;DR

Electron for maximum compatibility; Tauri for minimal bundle size. Electron (~5M weekly downloads) bundles Chromium + Node.js — proven at scale (VS Code, Slack, Discord). Tauri (~500K downloads) uses the OS's native WebView and Rust for backend — apps ship at 2-10MB vs Electron's 80-200MB. The tradeoff: Tauri's WebView renders differently per OS (WebKit on Mac, WebView2 on Windows), while Electron always uses Chromium.

Key Takeaways

• Electron: ~5M weekly downloads — powers VS Code, Figma desktop, 1Password, Discord
• Tauri: ~500K downloads — 10-100x smaller bundles, Rust backend, native WebView
• Neutralino: ~50K downloads — lightest option, zero Node.js dependency
• Electron app size: ~80-200MB — Tauri: ~2-10MB — Neutralino: ~1-5MB
• Tauri v2 — mobile support added (iOS + Android), game-changer for 2026

Electron (Battle-Tested)

// Electron — main process (Node.js)
// main.ts
import { app, BrowserWindow, ipcMain, dialog } from 'electron';
import path from 'path';

let mainWindow: BrowserWindow | null = null;

app.whenReady().then(() => {
  mainWindow = new BrowserWindow({
    width: 1200,
    height: 800,
    webPreferences: {
      nodeIntegration: false,         // Security: disable
      contextIsolation: true,         // Security: enable
      preload: path.join(__dirname, 'preload.js'),
    },
  });

  if (process.env.NODE_ENV === 'development') {
    mainWindow.loadURL('http://localhost:5173');    // Vite dev server
    mainWindow.webContents.openDevTools();
  } else {
    mainWindow.loadFile(path.join(__dirname, '../dist/index.html'));
  }
});

// IPC handler — handle calls from renderer
ipcMain.handle('open-file-dialog', async () => {
  const result = await dialog.showOpenDialog({
    properties: ['openFile'],
    filters: [{ name: 'JSON', extensions: ['json'] }],
  });
  return result.filePaths[0];
});

ipcMain.handle('read-file', async (_, filePath: string) => {
  const fs = await import('fs/promises');
  return fs.readFile(filePath, 'utf-8');
});

// Electron — preload script (bridge between main and renderer)
// preload.ts
import { contextBridge, ipcRenderer } from 'electron';

contextBridge.exposeInMainWorld('electronAPI', {
  openFile: () => ipcRenderer.invoke('open-file-dialog'),
  readFile: (path: string) => ipcRenderer.invoke('read-file', path),
  onMenuAction: (callback: (action: string) => void) => {
    ipcRenderer.on('menu-action', (_, action) => callback(action));
  },
});

// Electron — renderer (React/any web framework)
// Use the exposed API
declare global {
  interface Window {
    electronAPI: {
      openFile: () => Promise<string>;
      readFile: (path: string) => Promise<string>;
    };
  }
}

function FileLoader() {
  const [content, setContent] = useState('');

  const handleOpen = async () => {
    const filePath = await window.electronAPI.openFile();
    if (filePath) {
      const data = await window.electronAPI.readFile(filePath);
      setContent(data);
    }
  };

  return (
    <div>
      <button onClick={handleOpen}>Open File</button>
      <pre>{content}</pre>
    </div>
  );
}

Tauri (Lightweight, Rust)

// Tauri — src-tauri/src/main.rs (Rust backend)
#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]

use tauri::command;
use std::fs;

// Tauri commands — called from frontend
#[command]
fn read_file(path: String) -> Result<String, String> {
    fs::read_to_string(&path)
        .map_err(|e| e.to_string())
}

#[command]
async fn fetch_data(url: String) -> Result<String, String> {
    // reqwest async HTTP in Rust
    reqwest::get(&url)
        .await
        .map_err(|e| e.to_string())?
        .text()
        .await
        .map_err(|e| e.to_string())
}

fn main() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![read_file, fetch_data])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

// Tauri — frontend (React/Vue/Svelte)
import { invoke } from '@tauri-apps/api/tauri';
import { open } from '@tauri-apps/api/dialog';
import { readTextFile } from '@tauri-apps/api/fs';

async function loadFile() {
  // Native file dialog
  const filePath = await open({
    filters: [{ name: 'JSON', extensions: ['json'] }],
  });

  if (typeof filePath === 'string') {
    // Direct file system access via Tauri's FS API
    const content = await readTextFile(filePath);
    return JSON.parse(content);
  }
}

// Call Rust commands
async function fetchData(url: string) {
  const result = await invoke<string>('fetch_data', { url });
  return result;
}

// tauri.conf.json — app configuration
{
  "tauri": {
    "bundle": {
      "identifier": "com.myapp.app",
      "icon": ["icons/icon.icns", "icons/icon.ico"],
      "targets": "all"  // .dmg, .deb, .exe, .AppImage
    },
    "allowlist": {
      "fs": { "readFile": true, "writeFile": true, "scope": ["$HOME/**"] },
      "dialog": { "open": true, "save": true },
      "http": { "all": true }
    }
  }
}

Neutralino (Minimal)

// Neutralino — ultra-lightweight
// resources/js/main.js
Neutralino.init();

// File operations
async function readFile() {
  const entries = await Neutralino.filesystem.readFile('data.json');
  return JSON.parse(entries);
}

// Execute OS commands
const info = await Neutralino.os.execCommand('uname -a');
console.log(info.stdOut);

// Dialogs
const path = await Neutralino.os.showOpenDialog('Open File', {
  filters: [{ name: 'JSON Files', extensions: ['json'] }],
});
