I think I might just be too far from the target audience to understand this. I don’t see any of the other options as non “self hosted”, they aren’t backed by some cloud infrastructure owned by a company, those are all locally running apps on your device

Another way to put it is that those apps are only installed on a single device at a time, whereas with RomM setup on a server, so you can access your library from any device with a browser. There's a future where ES-DE and EmuDeck can pull games from, and push saves to, a central RomM server.

As Gantoine said, the main difference is that you can't access any of those tools from other device, only from the one where it's installed
