Electron, Tauri, Flutter, .NET MAUI and Qt compared for building cross-platform desktop apps — which one actually fits your team and product.
Why Cross-Platform Desktop Frameworks Matter
Building separate native apps for Windows, macOS and Linux triples your engineering cost for a desktop product. A cross-platform framework lets one codebase ship on all three — the trade-off is always somewhere between bundle size, performance, and how "native" the app actually feels. Here's how the main options compare in 2026.
1. Electron
Electron bundles Chromium and Node.js, so any web app becomes a desktop app with the same HTML/CSS/JS you already know. It's why Slack, VS Code, Discord and Figma are all built on it. The trade-off is well known: every Electron app ships its own copy of a full browser, so memory usage and install size are both heavy. Best fit: teams that already have a strong web codebase and want to reuse it directly.
2. Tauri
Tauri solves Electron's biggest complaint by using the operating system's own native webview instead of bundling Chromium — the same React, Vue or Svelte frontend, but a fraction of the binary size and memory footprint, with a Rust backend instead of Node. It's newer and the plugin ecosystem is smaller than Electron's, but for a new project in 2026 it's usually the better default if your team can pick up a little Rust for the native layer.
3. Flutter (Desktop)
Flutter isn't just for mobile — its desktop target compiles to native Windows, macOS and Linux binaries with the same Dart codebase, and because Flutter renders its own UI rather than relying on native widgets or a webview, it looks and performs identically across platforms. It's a strong choice specifically when you already need a mobile app from the same codebase, since Flutter covers both from day one.
4. .NET MAUI
Microsoft's evolution of Xamarin, .NET MAUI targets Windows, macOS, iOS and Android from a single C#/XAML codebase. It renders through native controls on each platform rather than a custom renderer, so apps feel closer to platform-native than Electron or Flutter — the trade-off is that "closer to native" also means more platform-specific quirks to handle. Best fit: teams already invested in the .NET ecosystem.
5. Qt (PySide / PyQt)
Qt has shipped cross-platform native desktop apps since long before "cross-platform" was a buzzword, and it's still one of the few frameworks that genuinely compiles to native code with native performance on every platform. PySide and PyQt bring it to Python, which matters if your team is already Python-heavy — for example, integrating a data pipeline or ML model directly into a desktop tool. The licensing (LGPL vs commercial) is worth checking early for commercial products.
Which One Should You Pick?
As a rough guide: choose Electron if you have an existing web app and want it on the desktop fast; Tauri for a new project where binary size and memory matter and your team can touch Rust; Flutter if you need mobile and desktop from one codebase; .NET MAUI if you're already a Microsoft shop; and Qt/PySide when you need real native performance and your team already knows Python or C++.
