Pick **Electron** when you need the most mature desktop runtime, predictable Chromium rendering, Node.js in the main process, and the widest packaging/updater ecosystem. Pick **Tauri** when installer size, memory use, and a smaller attack surface matter more than a pure-JavaScript backend. Pick **Neutralino** when the app is a lightweight utility and you only need a thin native window, tray, storage, and file/OS APIs around an existing web UI. Do not use this guide as a broad desktop-framework roundup. If you are comparing Flutter, Qt, .NET MAUI, native Swift/WinUI, or mobile targets too, start with [Best Desktop App Frameworks 2026](/guides/best-desktop-app-frameworks-2026). This page stays focused on the three JavaScript/WebView-style choices: **Tauri vs Electron vs Neutralino**. ## Fast Decision Table | Decision point | Electron | Tauri | Neutralino | | --- | --- | --- | --- | | Best default for | Mature cross-platform products | Small, secure-feeling desktop apps | Tiny utilities and wrappers | | Rendering engine | Bundled Chromium | OS WebView: WebView2 on Windows, WebKit/WKWebView on macOS/Linux variants | OS WebView | | Backend/runtime model | Node.js main process plus Chromium renderer | Rust backend commands plus web frontend | Built-in native API server; optional external extensions | | Package size posture | Largest, because Chromium ships with the app | Usually much smaller; WebView is supplied by the OS | Usually smallest for simple apps | | Memory posture | Highest baseline | Lower baseline for comparable simple apps | Lowest for simple wrappers | | Native API depth | Deep and battle-tested | Strong through Rust commands and official/community plugins | Useful but intentionally smaller | | Security posture | Good when hardened, but Node/IPC mistakes are common | Strong by default when permissions and commands are scoped | Token/allow-list model; smaller surface, smaller ecosystem | | Auto-update story | Mature third-party tooling such as electron-builder/electron-updater | Official updater plugin with signed updates | Manual/custom update flow | | Team fit | JavaScript/Node teams, complex desktop apps | Teams willing to own Rust and WebView testing | Teams shipping simple utilities fast | ## Key Takeaways - **Electron wins on maturity and rendering consistency.** It ships Chromium, so CSS/JS behavior is predictable across platforms, and the packaging ecosystem is deep. - **Tauri wins when bundle size, idle memory, and permission scoping matter.** Tauri 2.x pairs a web frontend with Rust commands and OS WebViews, so you trade a heavier toolchain for smaller app artifacts. - **Neutralino is not a Tauri clone.** It is a minimal WebView wrapper with a compact native API surface; it is best for utilities, internal tools, launchers, and dashboards that do not need a deep backend runtime. - **Prototype the operational surface before choosing.** File permissions, tray/menu behavior, code signing, deep links, crash reporting, and auto-updates usually expose the real framework fit faster than hello-world bundle numbers. - **Keep broad framework intent separate.** Use this guide for the three-way JavaScript desktop decision; use the broader [desktop framework roundup](/guides/best-desktop-app-frameworks-2026) when native UI stacks are in scope. --- ## What Changed Since Older Electron vs Tauri Advice The desktop-app decision used to be framed as "Electron is big, Tauri is small." That is still directionally true, but it is not enough for a 2026 production decision. Electron remains the proven runtime for apps that need a bundled browser, a Node.js main process, mature OS integrations, and packaging/updater tooling that many teams already understand. Tauri 2.x is now mature enough that teams can seriously choose it for production desktop apps, but they must accept Rust commands, OS-WebView variation, and a different permissions model. Neutralino stays deliberately narrow: it is attractive when the product is mostly a local web UI with a few native operations, not when you need a full application platform. The better comparison is therefore: 1. **Runtime control:** bundled Chromium + Node.js, Rust command layer, or minimal native API bridge. 2. **Distribution cost:** app size, signing/notarization, installers, update channels, and support burden. 3. **Security model:** renderer isolation, IPC/command boundaries, permissions, update signing, and dependency exposure. 4. **Web compatibility:** one Chromium version everywhere vs platform WebView differences. 5. **Team skill:** Node/Electron experience, Rust ownership, or a small wrapper around a web app. --- ## Electron: Choose the Proven Desktop Runtime Electron bundles Chromium and Node.js with your app. That makes it the easiest choice when a web team wants maximum desktop capability without introducing Rust or native UI frameworks. ```bash npm create electron-app@latest my-app -- --template=vite-typescript cd my-app npm start ``` A hardened Electron app usually has a main process, an isolated renderer, and a preload bridge: ```typescript // main.ts — Node.js context import { app, BrowserWindow, ipcMain, dialog, shell } from "electron"; import { join } from "node:path"; let mainWindow: BrowserWindow | null = null; function createWindow() { mainWindow = new BrowserWindow({ width: 1200, height: 800, webPreferences: { preload: join(__dirname, "preload.js"), contextIsolation: true, nodeIntegration: false, sandbox: true, }, }); mainWindow.loadFile(join(__dirname, "renderer/index.html")); } app.whenReady().then(createWindow); ipcMain.handle("dialog:openFile", async () => { const result = await dialog.showOpenDialog(mainWindow!, { properties: ["openFile"], }); return result.filePaths[0] ?? null; }); ipcMain.handle("shell:openExternal", (_event, url: string) => { return shell.openExternal(url); }); ``` ```typescript // preload.ts — narrow bridge between renderer and main import { contextBridge, ipcRenderer } from "electron"; contextBridge.exposeInMainWorld("desktop", { openFile: () => ipcRenderer.invoke("dialog:openFile"), openExternal: (url: string) => ipcRenderer.invoke("shell:openExternal", url), }); ``` Choose Electron when you need: - a complex desktop product surface such as a code editor, design tool, database GUI, or communication app; - consistent Chromium behavior on Windows, macOS, and Linux; - Node.js libraries in the desktop backend; - mature packaging, auto-update, crash reporting, and installer examples; - a team that already knows Electron hardening patterns. Avoid Electron when the app is a small utility where users will notice the installer size and memory baseline more than they notice Chromium consistency. --- ## Tauri: Choose Small Artifacts and Scoped Native Commands Tauri uses the operating system WebView for the frontend and Rust for native commands. That removes bundled Chromium from the app artifact, which is why Tauri apps usually ship much smaller than equivalent Electron apps. ```bash npm create tauri-app@latest my-tauri-app cd my-tauri-app npm install npm run tauri dev ``` A Tauri app exposes native behavior as Rust commands instead of giving the renderer direct Node.js access: ```rust // src-tauri/src/main.rs #[tauri::command] async fn read_project_file(path: String) -> Result { tokio::fs::read_to_string(path) .await .map_err(|error| error.to_string()) } #[cfg_attr(mobile, tauri::mobile_entry_point)] pub fn run() { tauri::Builder::default() .invoke_handler(tauri::generate_handler![read_project_file]) .run(tauri::generate_context!()) .expect("error while running tauri application"); } ``` ```typescript // frontend TypeScript import { invoke } from "@tauri-apps/api/core"; const contents = await invoke("read_project_file", { path: "/Users/example/project/package.json", }); ``` Choose Tauri when you need: - a much smaller installer and a lower idle-memory baseline than Electron for similar UI complexity; - Rust-backed commands for file, network, cryptography, or long-running local work; - a permission model where native capabilities are deliberately exposed rather than globally available; - signed update flows through Tauri's updater plugin; - a team willing to test WebView differences across Windows, macOS, and Linux. The Tauri tradeoff is real: platform WebViews are not identical. Windows WebView2 is Chromium-based, macOS uses WebKit/WKWebView, and Linux WebView behavior depends on installed libraries. If your app uses advanced CSS or browser APIs, budget for cross-platform WebView QA. --- ## Neutralino: Choose a Tiny Native Wrapper Neutralino wraps a web app in a native window and exposes a compact JavaScript API for OS, filesystem, storage, window, and process interactions. It does not try to be Electron with a smaller binary or Tauri without Rust; it is a smaller abstraction for smaller apps. ```bash npm install -g @neutralinojs/neu neu create my-app --template neutralinojs/neutralinojs-minimal cd my-app neu run ``` A minimal Neutralino config keeps the native surface explicit: ```json { "applicationId": "com.example.utility", "defaultMode": "window", "documentRoot": "/resources/", "enableNativeAPI": true, "tokenSecurity": "one-time", "nativeAllowList": [ "app.*", "filesystem.readFile", "filesystem.writeFile", "storage.*", "window.*" ], "modes": { "window": { "width": 1100, "height": 720, "resizable": true } } } ``` Choose Neutralino when you need: - a tiny app wrapper for an internal tool, launcher, local dashboard, file converter, or tray utility; - native window/storage/filesystem access without a full Node.js or Rust backend; - simple distribution where manual or custom updates are acceptable; - a small surface area and limited plugin needs. Avoid Neutralino when your app needs deep OS integration, complex background services, mature auto-update infrastructure, or a large ecosystem of desktop-specific packages. --- ## Bundle Size and Memory: Use Directional Ranges, Then Measure Your App Hello-world bundle and idle-memory numbers are useful only as a first filter. Electron is usually the largest because Chromium ships with the application. Tauri is usually much smaller because the OS provides the WebView. Neutralino is usually smallest for a simple wrapper. | Metric to test in your prototype | Electron expectation | Tauri expectation | Neutralino expectation | | --- | --- | --- | --- | | Minimal installer/app artifact | Largest | Much smaller | Smallest for simple apps | | Idle memory for simple shell | Highest | Lower | Lowest | | Rendering consistency | Highest because Chromium is bundled | Platform-dependent WebView behavior | Platform-dependent WebView behavior | | Native backend weight | Node.js process | Rust binary | Built-in API server plus optional extensions | | CI/build prerequisites | Node, native packaging dependencies | Node plus Rust/Cargo and platform targets | Node plus Neutralino CLI | If the app is a developer tool with large data grids, terminals, plugins, and background services, the UI and workload can dominate the baseline. Build one vertical slice with the real shell, file access, tray behavior, updater, and a representative heavy screen before making the final call. --- ## Security and Permission Model Electron security depends on disciplined configuration: `contextIsolation: true`, `nodeIntegration: false`, `sandbox: true` where practical, strict Content Security Policy, narrow preload APIs, and careful IPC validation. Electron is secureable, but it gives teams enough power to create footguns. Tauri pushes teams toward a narrower native-command seam. The renderer calls explicit commands or plugin APIs; the Rust side validates inputs and owns native behavior. That model is a better default for many apps, but it still needs careful command design and plugin permission review. Neutralino reduces the surface by being smaller, then relies on token security and explicit native API allow-lists. That is attractive for utilities, but the smaller ecosystem means you own more custom integration work when the app grows beyond the core APIs. --- ## Auto-Updates, Signing, and Release Operations The release pipeline often decides this comparison: - **Electron:** mature packaging and update tooling through Electron Forge, electron-builder, and electron-updater. Good fit when your team wants a documented path for installers, GitHub Releases/S3 update feeds, and platform signing. - **Tauri:** Cargo-based builds and Tauri's updater plugin. Good fit when signed update payloads and a Rust-native release pipeline are acceptable. - **Neutralino:** no comparable batteries-included updater story. Good fit when manual updates, a custom version-check flow, or a controlled internal distribution channel is acceptable. Before choosing, run a release rehearsal: build signed artifacts, install them on a clean VM, exercise first launch, trigger an update, and verify rollback behavior. --- ## Which Should You Pick? ### Pick Electron if - the app is a complex desktop product with heavy UI and native integration needs; - your team needs Chromium consistency more than tiny installers; - Node.js libraries are core to local app behavior; - mature packaging, updater, and community examples reduce delivery risk; - you are building something closer to VS Code, Slack, Discord, Figma desktop, or a database GUI than a small utility. ### Pick Tauri if - startup, memory, app size, and security posture are product requirements; - you can own Rust commands and cross-platform WebView QA; - the web frontend does not require exact Chromium behavior everywhere; - you want a stricter seam between web UI and native capabilities; - you are shipping a consumer productivity tool, local-first app, or internal desktop tool where resource usage matters. ### Pick Neutralino if - the app is a lightweight wrapper around an existing web UI; - you need a tiny installer and a minimal native API surface; - you can accept a smaller ecosystem and a custom/manual updater story; - the product is a utility, kiosk shell, launcher, tray app, or internal helper. --- ## Internal Links for Adjacent Decisions - For the broader desktop stack decision, use [Best Desktop App Frameworks 2026](/guides/best-desktop-app-frameworks-2026). - For the two-way incumbent/challenger comparison, use [Electron vs Tauri 2026](/guides/electron-vs-tauri-2026). - For adjacent cross-platform mobile choices, use [React Native vs Expo vs Capacitor](/guides/react-native-vs-expo-vs-capacitor-cross-platform-mobile-2026). - Compare package health for [Electron vs Tauri](/compare/electron-vs-tauri) on PkgPulse. --- ## Methodology and Sources This refresh checked official documentation and current package metadata on 2026-05-16 PDT. Package versions observed from npm during the refresh were `electron@42.1.0`, `@tauri-apps/cli@2.11.1`, `@tauri-apps/api@2.11.0`, `@neutralinojs/neu@11.7.1`, and `@neutralinojs/lib@6.7.0`.
