Very legitimate concern. I use the Realm database in production and it has proven to be a very good decision. Huge advantage over Parse is that the database is open source. If something did happen, the open source community would probably be enough to carry it. If not, it is just a local persistence store, so not hugely difficult to swap out for something else.

This new mobile platform is not (as far as I can tell) open source and has completely unknown pricing beyond the free tier. I certainly wouldn't go near it, even though it looks great.

Well, I'm not sure about the pricing, but according to this page (https://realm.io/products/realm-mobile-platform/) you can host the mobile platform on-premises.
