Cross-Platform Desktop Apps: Electron vs Flutter vs Native

If you need a desktop application that runs on Windows, macOS, and Linux, you have three main options: Electron, Flutter, or building native apps for each platform separately. We've shipped production apps with all three approaches.

Here's what to actually expect from each.

Electron: The Web-Based Approach

Electron packages a Chromium browser and Node.js runtime into a desktop app. Your app is essentially a web app running in its own window. VS Code, Slack, Discord, and Figma all use Electron.

The advantage is speed of development. If your team builds web apps, they can build Electron apps immediately. React, Vue, Angular — whatever you use on the web works in Electron. The ecosystem is mature and well-documented.

The downside is resource usage. Every Electron app ships its own copy of Chromium. Memory usage starts higher than native apps. On modern machines this is rarely a problem, but for resource-constrained environments, it matters.

Electron is the right choice when your team has web skills, when the app is an extension of an existing web product, or when development speed outweighs performance optimization.

Flutter Desktop: The New Contender

Flutter's desktop support has matured significantly. The same Dart codebase that runs your mobile app can now target Windows, macOS, and Linux. If you're already building a Flutter mobile app, adding desktop is relatively straightforward.

Flutter renders its own UI rather than using native platform widgets. This means your app looks identical across platforms — the same trade-off as Flutter on mobile. It also means smaller binary sizes and lower memory usage than Electron.

The downside is a smaller ecosystem for desktop-specific features. File system dialogs, system tray integration, and native menu bars require platform-specific plugins that aren't always as polished as Electron's equivalents.

Flutter desktop is the right choice when you already have a Flutter mobile app, when you need consistent UI across platforms, or when you're targeting mobile and desktop from one codebase.

Native Development: The Heavyweight

Building native means using each platform's own frameworks. Swift/AppKit for macOS, C#/WPF for Windows, GTK for Linux. You get the best performance, the most native-feeling UI, and full access to platform-specific features.

The cost is obvious: you're maintaining three separate codebases. Three sets of bugs. Three deployment pipelines. Three times the development effort.

Native makes sense when performance is critical (think audio/video processing, CAD software, or games), when platform-specific integration is deep (system services, hardware drivers), or when your app needs to feel indistinguishable from built-in OS applications.

For most business applications, native development for multiple platforms isn't justified.

Java Desktop: Still Relevant

We'd be remiss not to mention Java desktop frameworks like JavaFX. They're not trendy, but they're battle-tested. If your organisation runs on Java, if you need tight integration with Java backends, or if your developers are Java specialists, JavaFX delivers solid cross-platform desktop apps.

We've built enterprise desktop applications with JavaFX that have been running reliably for years. Not every project needs the newest framework.

How We Decide

For most new projects, we start with Electron or Flutter desktop depending on the client's existing technology and whether mobile is also in scope. We reach for native only when there's a specific technical requirement that cross-platform tools can't meet.

The decision usually comes down to: what skills does your team have, does the app need to run on mobile too, and how critical is native platform integration?
