Many features in the current iterations of macOS and iOS are "borrowed" from others. The time has come for Apple to borrow this too.

I’m a long time Fluid user, best 5$ I’ve ever spent, but the app is not longer updated. At the moment it works in Monterey, but I don’t know if it will still work in Sonoma.

Flotato doesn’t seem to be offering much more in the Pro version https://flotato.com/buy.html
but WebCatalog offers Cloud backup & sync, Private app library & App Lock https://webcatalog.io/pricing/

I’ll keep using Fluid for as long as I can.
