They simply shared a post titled:

Nice - I didn’t realize that the GoG installer was portable.
I wish their settings had custom connections. Like, If I could have a portable version that connects to my NAS and downloads/installs my offline/saved GoG games; that’d be the sweet spot. If anyone has suggestions for a setup like this lemme know!
I have the offline installer stored on my NAS and use GameVault[1] as a local installed web interface to access my digital game library.
