And Hasura, Postgraphile et al too. These, as well as PostgREST also give you much more flexibility in the form of plugins in library mode and other such things - they also generate the actual queries for you, via introspection, as opposed to this which requires you to write the query yourself. I think there's certainly space for this project, i.e. hand-written queries, on any database (Postg[REST|raphile] both only work with Postgres of course, not sure about Hasura). Not sure it will succeed without support for more forms of Serverless deployment, primarily Lambda.
