We've built and launched our community platform on Hasura + PG RDS. Row-level permission has been a time-saver to launch a product quickly. Stability has been great - our Hasura container hasn't crashed / restarted in the last 9 months.

Their are downsides (it has proven frustrating for us to implement the authentication part for a role that is not user or admin) but I would definitely recommend Hasura to experienced developpers.
