Tauri vs Electron vs Neutralinojs: Best Desktop App Framework (2026)
Building a desktop app with web technologies? Your choice of framework determines your app's size (2MB vs 200MB), memory usage, security model, and update experience. Here's the real comparison.
Quick Comparison

Tauri: The Modern Choice
Tauri builds desktop apps using your system's native webview and a Rust backend. The result is tiny, fast, secure applications.
Strengths
Tiny bundles. A basic Tauri app is 2-5MB. The same app in Electron: 150MB+. Your users will notice the difference on download and disk.
Low memory. Tauri apps use 30-80MB of RAM vs. Electron's 100-300MB+. On a laptop with 20 Chrome tabs open, this matters.
Security-first. Tauri's permission system is granular. By default, your frontend can't access the filesystem, network, or OS APIs. You explicitly whitelist capabilities. Electron gives the renderer process access to everything by default.
Rust backend. Write performance-critical logic in Rust. File processing, cryptography, data transformation — all at native speed.
Mobile support. Tauri 2.0 supports iOS and Android. Build one codebase for desktop and mobile.
Auto-updates. Built-in update system with delta updates (only download what changed).
Weaknesses
Rust learning curve. If your team doesn't know Rust, the backend requires learning a new language. Simple IPC and commands are manageable, but complex Rust logic has a steep curve.
System webview inconsistencies. Your app renders differently on Windows (WebView2/Edge), macOS (WebKit/Safari), and Linux (WebKitGTK). Testing across platforms is essential.
Smaller ecosystem. Fewer plugins, fewer examples, fewer Stack Overflow answers than Electron.
Webview limitations. System webviews may not support the latest web APIs. Features available in Chrome/Electron might not work in Safari's WebKit on macOS.
Best For
New projects that prioritize small size, low memory, security, or mobile support. The default choice for new desktop apps in 2026.
Electron: The Established Giant
Electron bundles Chromium and Node.js to create a consistent, fully-featured desktop environment. VS Code, Slack, Discord, Notion, and Figma all use it.
Strengths
Consistent rendering. Same Chromium version on every platform. If it works in Chrome, it works in Electron. No cross-browser webview issues.
Full Node.js access. Spawn processes, access the filesystem, use any npm package — the entire Node.js ecosystem is available.
Massive ecosystem. Thousands of plugins, extensive documentation, and solutions for every problem you'll encounter.
Battle-tested at scale. VS Code serves millions of users. Discord handles real-time communication. Electron's reliability at scale is proven.
Developer familiarity. If your team knows JavaScript/TypeScript, they're productive immediately. No Rust required.
Weaknesses
Huge bundle size. 150-200MB minimum. Each Electron app ships its own Chromium browser. 5 Electron apps = 5 copies of Chromium.
High memory usage. 100-300MB+ per app. Running multiple Electron apps simultaneously consumes significant RAM.
Security surface. Bundling Chromium means your app inherits Chromium's security surface area. Proper sandboxing requires careful configuration.
Slow startup. Loading Chromium takes 1-3 seconds. Users notice compared to native apps.
Update size. Full app updates are large (150MB+). Even minor updates require re-downloading most of the bundle.
Best For
Apps that need consistent cross-platform rendering, full Node.js access, or rapid development with an all-JavaScript team. Proven choice for complex applications.
Neutralinojs: The Lightweight Option
Neutralinojs takes a minimal approach — system webview + lightweight C++ backend + JavaScript API.
Strengths
Smallest footprint. 2-3MB bundles and ~20-50MB memory usage. Even smaller than Tauri.
Simple. No Rust to learn (unlike Tauri), no massive framework to understand (unlike Electron). JavaScript frontend + simple native API.
Fast startup. Near-instant launch. No Chromium to load, lightweight C++ backend.
Portable mode. Can run as a portable app without installation.
Weaknesses
Limited native APIs. Far fewer system APIs than Tauri or Electron. Complex native interactions may not be possible.
Smaller community. Least popular of the three. Fewer resources, plugins, and community support.
No mobile. Desktop only (Windows, macOS, Linux).
Basic auto-updates. Update mechanism is simpler and less robust than Tauri or Electron.
System webview issues. Same cross-platform rendering inconsistencies as Tauri.
Best For
Simple utilities, internal tools, and apps that don't need extensive native API access. When you want the smallest possible footprint.
Real-World Comparison
Building a Markdown Editor
| Metric | Tauri | Electron | Neutralinojs |
|---|---|---|---|
| Bundle size | 3MB | 160MB | 2MB |
| Memory (idle) | 45MB | 120MB | 25MB |
| Startup time | 0.3s | 1.5s | 0.2s |
| Dev complexity | Medium | Low | Low |
Building a Complex IDE
| Metric | Tauri | Electron | Neutralinojs |
|---|---|---|---|
| Feasibility | ✅ Possible | ✅ Proven (VS Code) | ⚠️ Limited |
| Performance | Excellent | Good | Good (basic features) |
| Plugin system | Build yourself | Mature (extensions API) | Very limited |
| Ecosystem | Growing | Massive | Limited |
For complex apps, Electron's ecosystem advantage is significant. For simple apps, Tauri or Neutralinojs deliver better user experience through smaller size and lower resource usage.
Development Experience
Setting Up
Tauri:
# Requires Rust toolchain
npm create tauri-app@latest
Electron:
npm init electron-app@latest my-app
# or use electron-vite, electron-forge
Neutralinojs:
npm install -g @neutralinojs/neu
neu create my-app
Frontend Framework Support
All three work with any web framework: React, Vue, Svelte, Solid, Angular. Your frontend code is largely portable between them.
Backend Logic
Tauri: Write Rust commands, call from frontend via invoke().
Electron: Write Node.js in main process, communicate via IPC.
Neutralinojs: Use the provided JavaScript API for native operations.
Migration Considerations
Electron → Tauri
- Frontend code transfers directly (it's still web)
- Node.js backend logic must be rewritten in Rust
- IPC patterns are similar but API is different
- Test thoroughly on all platforms (webview differences)
- Several migration guides and tools exist
Neutralinojs → Tauri
- Frontend code transfers directly
- Backend logic is minimal (Neutralinojs has few native APIs)
- Generally straightforward migration
FAQ
Which should I choose for a new project in 2026?
Tauri for most new projects. Electron if you need absolute cross-platform rendering consistency or extensive Node.js/npm integration. Neutralinojs for simple utilities.
Can Tauri replace Electron for complex apps?
For most apps, yes. For apps requiring deep Node.js integration, embedded web browsers, or Chromium-specific APIs — Electron is still the safer choice.
Is the Rust learning curve worth it for Tauri?
For simple apps, you barely need Rust — basic commands and file operations are well-documented. For complex backends, you'll need real Rust knowledge. Many teams write minimal Rust and keep logic in the web frontend.
What about PWAs instead?
Progressive Web Apps avoid desktop frameworks entirely. If your app doesn't need filesystem access, system tray, or native integrations, a PWA might be all you need. No framework required.
The Verdict
- Tauri for new projects: smallest bundles, best security, mobile support, modern architecture. Accept the Rust learning curve.
- Electron for complex applications: proven at scale, consistent rendering, massive ecosystem. Accept the size and memory tradeoffs.
- Neutralinojs for simple tools: smallest footprint, easiest to learn. Accept the limited native APIs.
For most developers starting a desktop app in 2026, Tauri 2.0 is the right choice. Electron remains the pragmatic choice when you need its ecosystem or your team is all-JavaScript.
