The very fact that Nextjs vibe projects need an external (and paid!) background jobs / async service show how much of an anti pattern that this framework and similar are. Just use a sensible stack from day one that can handle concurrency out of the box like Elixir or something with established open source background jobs library. Then you can worry less about this kind of paid 3rd party nonsense. Ditto on auth. I just can't fathom outsourcing these types or core functionalities, the operational, security and cost risks make very little sense when there's libraries that do this out of the box.
