gql.tada is indeed very impressive and I think shares many of the same values as Grats. That said, I believe that today they only support the client path. Editor features and type generation for queries/mutations and fragments, although they do have interest in having a server story as well: https://github.com/0no-co/gql.tada/issues/10

Thanks for clarifying and may I say it warms my heart to see the spirit of open, enthusiastic cross-project collaboration represented in that issue thread.
