Wails Has a Free API That Builds Desktop Apps With Go Backend and Web Frontend

Wails is like Tauri but with Go instead of Rust. Your web frontend (React, Vue, Svelte) + Go backend = native desktop app using OS webview.

Quick Start

go install github.com/wailsapp/wails/v2/cmd/wails@latest
wails init -n myapp -t react-ts
cd myapp && wails dev

Go Backend

// app.go
type App struct { ctx context.Context }

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

func (a *App) GetUsers() ([]User, error) {
    return db.GetAllUsers()
}

Frontend Calls Go

import { Greet, GetUsers } from '../wailsjs/go/main/App'

const greeting = await Greet('World')    // "Hello World!"
const users = await GetUsers()           // typed automatically

Wails vs Tauri vs Electron

Feature	Wails	Tauri	Electron
Backend	Go	Rust	Node.js
Size	5-15MB	3-10MB	150MB
RAM	40MB	30MB	150MB+
Learning	Easy (Go)	Medium (Rust)	Easy (Node)

The Bottom Line

If you know Go, Wails is your desktop framework. Easier than Tauri's Rust, 10x smaller than Electron.
