What's with the name?
When I saw WebView, I thought "What I really want is tooling around building a WebView app, a bit like Rails is to Ruby". So initially it was a play on words (Webview on Rails). It just so happened to also be a homophone of the English name for the Country I am from. So it stuck.
Is this an alternative to Electron?
Depends on your requirements. It's designed to make it easy for Go programmers to make lightweight desktop applications or add a frontend to their existing applications. Wails v2 does offer native elements such as menus and dialogs, so it is becoming a lightweight electron alternative.
