Yeah, this title is currently overadvertising the product. Without even getting into the non-OLTP DB parts of Firebase, Hasura is much further along towards being a Firebase replacement. It already handles auth and a basic admin UI for both the schema and data. I respect the vision and welcome more competition, but this seems to just stitch a "push" system to Postgrest for now (with no auth to boot).

Hasura also some limited support for generated multi-table transactional APIs, which Postgrest doesn't. Meanwhile, Firebase supports arbitrary read-modify-write transactions.

This team has its work cut out for them and I can see a fierce competition with Hasura and Firebase.
