Electron alternatives in 2026: lighter ways to build desktop apps

If you have ever opened Activity Monitor and watched an Electron app consume 800 MB of RAM to display a chat window, you know why people keep looking for alternatives. Electron made desktop app development accessible by bundling Chromium, but the cost is real: large binaries, high memory usage, and startup times measured in seconds rather than milliseconds.

In 2026, the alternatives are actually viable. I have shipped production apps with several of them, and the ecosystem looks very different from even two years ago. What follows is what each option does well and where it falls short.

Tauri 2: the most mature alternative

Tauri is the closest thing to a drop-in Electron replacement. You write your frontend in HTML, CSS, and JavaScript, but instead of bundling Chromium, Tauri uses the operating system’s native WebView. The backend is Rust.

Tauri 2 shipped with mobile support (iOS and Android), a plugin system, and better inter-process communication. A basic Tauri app starts around 3-5 MB on disk and uses 30-60 MB of RAM at idle. That is an order of magnitude less than the equivalent Electron build.

#[tauri::command]
fn greet(name: &str) -> String {
    format!("Hello, {}!", name)
}

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

The tradeoff is the WebView itself. On Windows, Tauri uses WebView2 (Chromium-based Edge). On macOS, it uses WKWebView (Safari). On Linux, it uses WebKitGTK. Your app will render differently across platforms because the rendering engines differ. CSS that works on macOS might break on Linux. JavaScript APIs available in WebView2 might not exist in WebKitGTK. You are trading Electron’s consistent Chromium for lower resource usage and platform-native rendering.

Tauri is the right choice when your team already knows web technologies and you want smaller binaries. It is the safest bet in this list for production use in 2026.

Wails: Go instead of Rust

Wails does the same thing as Tauri (native WebView + compiled backend) but uses Go instead of Rust. If your team writes Go, this matters more than any technical difference between the two frameworks.

Wails 2 shipped with solid tooling. You get hot reload, TypeScript bindings generated from your Go structs, and a CLI that handles the build pipeline.

type App struct {
    ctx context.Context
}

func (a *App) Greet(name string) string {
    return fmt.Sprintf("Hello, %s!", name)
}

func main() {
    app := &App{}
    wails.Run(&options.App{
        Title:  "My App",
        Bind: []interface{}{
            app,
        },
    })
}

The problem with Wails compared to Tauri is ecosystem size. Fewer plugins, fewer examples, fewer people writing about it. The Go-to-JavaScript bridge is clean, but Go’s garbage collector adds unpredictable latency spikes that Rust does not have. For most desktop apps, this does not matter. For a real-time application, it can.

Wails is worth picking if you are a Go shop and want something lighter than Electron without learning Rust.

Flutter: Google’s bet

Flutter expanded from mobile to desktop and now targets Windows, macOS, and Linux. It renders everything with Skia (its own 2D rendering engine), so you get pixel-perfect consistency across platforms. No WebView weirdness.

The performance is good. Flutter apps start fast, use reasonable memory (60-120 MB for a typical app), and the rendering is smooth at 60fps. Dart is easy to learn if you know JavaScript or Java.

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Hello')),
      body: Center(child: Text('Hello, Flutter')),
    );
  }
}

The risk with Flutter is Google. The company has a history of abandoning projects. Flutter is widely used and unlikely to disappear tomorrow, but relying on a Google-controlled framework for a desktop app is a calculated bet. Flutter desktop also does not feel native. The controls look like Material Design or Cupertino approximations, not real macOS or Windows UI. Users notice.

Flutter makes sense if you are already building a mobile app and want a desktop version with minimal extra work. Starting fresh with Flutter for desktop only is harder to justify.

GPUI: Rust-native, GPU-first

GPUI is different from everything else on this list. There is no WebView, no browser engine, no HTML. GPUI is a GPU-accelerated UI framework written in Rust that renders directly through Metal on macOS and Vulkan elsewhere. It powers Zed, the code editor that launched in 2024 and is known for being fast.

fn render(&mut self, _cx: &mut ViewContext<Self>) -> impl IntoElement {
    div()
        .flex()
        .p_4()
        .gap_2()
        .child("Hello, GPUI")
        .child(
            Button::new("click-me", "Click me")
                .on_click(|_event, cx| {
                    println!("clicked");
                })
        )
}

A GPUI app uses 15-40 MB of RAM at idle. The binary size is small. Startup is near-instant because there is no WebView to initialize. Text rendering is crisp at any scale because GPUI handles subpixel rendering and font rasterization itself.

The catch is maturity. GPUI was built for Zed first and extracted as a general framework second. The documentation is thin. The API surface is large. Concepts like View, Model, and ViewContext take time to learn. The ecosystem of third-party components is small compared to Tauri or Flutter.

If you are building an editor, IDE, creative tool, or any app where frame-perfect rendering and low latency matter, GPUI is worth the investment. For a broader comparison of Rust GUI frameworks, see my earlier post on GPUI vs egui vs iced.

.NET MAUI and Avalonia: the C# path

If you come from C# and .NET, MAUI (the evolution of Xamarin.Forms) and Avalonia are your main options. MAUI is Microsoft’s official cross-platform UI framework. Avalonia is an open-source alternative with a broader platform reach.

Avalonia renders with its own engine, similar to how Flutter works. It supports Windows, macOS, Linux, and even WebAssembly. MAUI sticks closer to native controls but has had quality problems since launch. Many .NET developers I talk to in 2026 prefer Avalonia over MAUI for new projects.

The advantage here is C# itself. If your team writes C#, these frameworks integrate with your existing ecosystem. The disadvantage is that neither has the momentum of Tauri or Flutter outside the .NET world.

a quick comparison

These numbers are from my own testing on macOS with basic hello-world to medium-complexity apps. Your mileage will vary with actual application logic.

how to decide

Start with what your team already knows. If you have web developers, Tauri is the easiest transition. If you have Go developers, try Wails. If you have C# developers, look at Avalonia. Framework quality matters less than shipping something your team can maintain.

If performance is the primary requirement, the choice narrows. Tauri gives you the best balance of performance and ecosystem maturity. GPUI gives you the best raw performance but requires more upfront investment. Flutter is a solid middle ground if you accept the non-native feel.

For more on building with Rust desktop frameworks, the getting started guide covers setting up a GPUI project from scratch. I also wrote about scaling a GPUI prototype to production if you want to understand what that investment looks like in practice.

a note on gpui-starter

I built gpui-starter to make the GPUI onboarding less painful. It is a production-ready boilerplate with multi-page navigation, theming, i18n, form validation, a command launcher, macOS tray integration, SQLite persistence, auto-updating, and crash reporting. If you want to try GPUI without spending a month on infrastructure, start here and see if it fits your project.
