This is the true big benefit, the others talking about over fetching are not wrong but overfocusing on a technical merit over the operational ones.

My frontend developers had their minds blown when they realized that because we’re using Hasura internally, the only backend work generally needed is to design the db schema and permissioning, and then once that’s done frontend developers aren’t ever blocked by anything (which is not a freedom that I would want to give to untrusted developers, hence emphasis on internal usage of GQL)

(Unfortunately Hasura has shifted entirely into this VC-induced DDN thing that seems to be a hard break from the original product, so I can’t recommend that anymore… postgraphile is probably the way)
