Wails is a Go framework for building cross-platform desktop applications using web frontends (HTML/CSS/JS). It provides a CLI tool for project scaffolding, development server, and building. The architecture consists of a Go backend that communicates with an embedded WebView via a binding system that auto-generates TypeScript/JavaScript wrappers for Go services. It supports Windows (WebView2), macOS (WebKit), Linux (GTK/WebKit), and mobile (iOS/Android). Key entry points include `application.New()` in v3 and `wails.Run()` in v2. External dependencies include the WebView2 runtime on Windows, WebKitGTK on Linux, Cocoa on macOS, and various system libraries. The repository contains both v2 (legacy) and v3 (current) versions, with v3 introducing a new binding generator, built-in task runner (`wake`), improved service lifecycle, and cross-platform scaffolding.
