The Hasura GraphQL Engine fronts a Postgres database instance and can accept GraphQL requests from your client apps. It can be configured to work with your existing auth system and can handle access control using field-level rules with dynamic variables from your auth system.

You can also place the engine behind a central GraphQL proxy that fronts multiple GraphQL APIs via schema stitching.

Hasura works with any GraphQL client. We recommend using Apollo Client. See awesome-graphql for a list of clients.
