About Hasura
Hasura is the instant GraphQL engine — connect it to a PostgreSQL database and get a fully functional GraphQL API with queries, mutations, and real-time subscriptions automatically generated from your schema, in 30 seconds.
Without Hasura: build a GraphQL API manually — define resolvers for every type, every field, handle N+1 with DataLoader, implement authorization checks per field.
With Hasura: connect to PostgreSQL, get GraphQL for every table, column, and relationship automatically. Authorization rules defined at the database level. Done in 30 seconds.
Hasura''s permission system: define row-level security rules in Hasura''s UI. "A user can only query orders where user_id = session_user_id". Enforced automatically on every GraphQL query — not in application code.
Real-time subscriptions: `subscription { orders { id status } }` opens a WebSocket and streams updates whenever a matching row changes. No polling, no custom WebSocket code.
Hasura Remote Schemas: combine your Hasura PostgreSQL GraphQL with external GraphQL APIs (your custom Node.js service) into a unified GraphQL graph. One endpoint, multiple backends.
Hasura vs PostGraphile: both auto-generate GraphQL from PostgreSQL. Hasura has a UI console and cloud offering. PostGraphile is more flexible for complex authorization and custom business logic.
