Hasura GraphQL Engine is an open-source engine that auto-generates instant, realtime GraphQL APIs (and REST endpoints) over existing databases like PostgreSQL, MongoDB, SQL Server, ClickHouse, and BigQuery, with fine-grained access control and webhook triggers on database events. It is developed as a large mono-repo containing both the stable V2 engine and the newer V3 (DDN) architecture with open-source data connectors and TypeScript/Python/Go SDKs for custom business logic.

Use cases

• auto-generate a graphql api from my postgres database
• add realtime subscriptions to my existing database
• expose mongodb data through a graphql endpoint
• add fine-grained role-based access control to database apis
• trigger webhooks when database rows change
• federate multiple data sources into a single graphql supergraph
• build a backend api without writing server code

When to choose

• you want instant, auto-generated GraphQL APIs over existing databases without writing resolvers
• you need realtime subscriptions and fine-grained authorization on your data layer
• you want to unify multiple databases and services behind one composable GraphQL endpoint
• you prefer declarative metadata-driven API configuration over hand-coded backends

When to avoid

• you need full control over custom resolver logic and prefer a code-first GraphQL server
• your data sources are not among the supported connectors (Postgres, MongoDB, SQL Server, ClickHouse, BigQuery, etc.)
• you want a lightweight minimal API layer and find the engine's metadata/ops overhead excessive
• you depend heavily on the legacy V2 feature set and are not ready to migrate to the V3/DDN architecture
