I think so but you do need to set it up with your steam account and connect all that which is a bit of set up. Once you have it up though you can connect all of your launchers to it and then just have everything in one spot. I use it mostly for my GOG, Steam and Game Pass games.
As for steam, have you tried GOG Galaxy at all? I use it as my main launcher and I love it.
I’ve heard of it but never actually used it. Is it much faster than Steam?
