Prisma is a little bit lower level -- you'd use it within a node backend to get data to and from the database in a typesafe way. Hasura could be used for the same thing, but you'd have to spend some time setting up your own JS client to use within a backend to talk to Hasura. I think Hasura shines a bit more for powering client side apps directly, who just make GraphQL calls right to the "database" service.
