To the developer: please reconsider your approach, because as of right now nobody can use this and still have their customers trust them. To everyone else, until there's a 2.0 or self-hosted version of this, Hasura+Metabase was recommended for this in a HN thread last year and looks pretty neat, if not covering the exact same usecases.
(Yes, I realize that the same is true of a database hosted in AWS/Azure/GCP. But you can sue them if someone gets access to your data through them, and the US Government and every major bank uses one of those services, so I'd be more willing to believe in them vs a early stage startup).
