Wails enables developers to create desktop applications by wrapping Go backend code and web frontend technologies into a single binary executable. It bridges Go and JavaScript through method binding, auto-generated TypeScript definitions, and a unified eventing system.
Use Wails when building desktop applications where you want to leverage web technologies for the UI while using Go for performance-critical backend operations. It's particularly valuable when creating lightweight desktop tools, system utilities, or native applications that need native menus, dialogs, and OS integration without Electron's overhead.
