Electron not supporting ARM or other non-x86 platforms is a big problem that I was not aware of. I wonder if that will change with Microsoft starting to make ARM laptops and Apple being rumored to switch to ARM sometime in the future.

From https://electronjs.org/docs/tutorial/support:

Linux The prebuilt ia32 (i686) and x64 (amd64) binaries of Electron are built on Ubuntu 12.04, the armv7l binary is built against ARM v7 with hard-float ABI and NEON for Debian Wheezy.

Oh hey, they finally added vestigial Arm support looks at site for Linux.

Running Electron apps on Windows for ARM devices is possible by using the ia32 binary.

lol

Portability is not Electron's strong suit despite all the marketing hype to the contrary.

The announcement this whole discussion links to talks about the new ARM support, so I am confused as to what you are talking about.
