Only if we restrict "all platforms" to mean Windows, macOS, and Linux.

Building and porting Electron appears to be a horrific experience [1], which limits its cross-platform utility. It's only recently that someone pulled the heroics of getting Electron 4 (!) into FreeBSD ports; I still can't run VS Code on OpenBSD.

Meanwhile I've yet to encounter an OS with an X11 display where I can't run a Qt app. So I certainly wouldn't hold Electron up as a paragon of cross-platform support.
