For me (and please correct me if I'm wrong, Instant team) the largest difference and a major source of frustration in trying Instant is that you don't have a backend. You get a real-time database with RLS and a sync engine. You don't get to run business logic. You don't get to write queries by name and gain the ability to migrate the schema as long as the query shapes match.

If by backend you mean functions, you are right, we don't support this just yet! We give you an Admin SDK, which you can run in frameworks like NextJS, or inside systems like CF workers. We are definitely thinking about bringing this as a first-class citizen.
