MyGo

Desktop apps in Go, with a web frontend or a native UI.

Each MyGo window shows one of two kinds of interface, and one app can mix them:

• A web page, in the webview the OS already has: WKWebView on macOS,

• Native UI, written in Go alone with package ui and

Either way, an app is a single Go binary of a few megabytes, focused on low memory and CPU use.

• Pure Go, no cgo: build for every platform from any machine.
• Typed IPC for pages: bind Go services, stream values through channels

• A Go UI toolkit for native UI: flexbox and grid layout, widgets, text

• Desktop APIs for both: windows, menus, tray, dialogs, notifications,

• Ready to ship: app bundles and disk images, Windows installers, Debian

A window with a web page, whose frontend calls Go:

type Greeter struct{}
// Greet returns a greeting.
func (Greeter) Greet(name string) string { return "Hello, " + name }
func main() {
	mygo.Bind(Greeter{})
	mygo.App.WhenReady(func() {
		mygo.NewWindow(mygo.WindowOptions{Title: "Hello", URL: "/"})
	})
	if err := mygo.App.Run(); err != nil {
		log.Fatal(err)
	}
}

import { Greeter } from "./mygo"; // generated
document.body.textContent = await Greeter.greet("Ada");

A window with native UI, whose view is a Go function of the app's state:

type counter struct{ n int }
func (s counter) view(c ui.Context) {
	ui.Column(c).Fill().Center().Gap(12).Children(func() {
		ui.Text(c, fmt.Sprint(s.n)).FontSize(40).Bold()
		if ui.PrimaryButton(c, "Increment").Clicked() {
			s.n++
		}
	})
}
func main() {
	s := &counter{}
	mygo.App.WhenReady(func() {
		mygo.NewWindow(mygo.WindowOptions{
			Title:   "Counter",
			Content: ui.View(s.view),
		})
	})
	if err := mygo.App.Run(); err != nil {
		log.Fatal(err)
	}
}

Getting started

With Go 1.27+ and Bun, create an app with a web frontend:

bunx mygo-cli init my-app      # or: npx mygo-cli init my-app
cd my-app
bun run dev

An app of native UI needs Go alone:

go run github.com/egoist/mygo/cmd/mygo@latest init -template native my-app
cd my-app
go tool mygo dev
