Hasura DDN

Hasura DDN builds governed GraphQL APIs over databases, code, and APIs using metadata-driven supergraphs.

Hasura DDN

Hasura DDN is a data access platform for creating, deploying, and evolving GraphQL APIs across databases, services, code, and APIs. It uses metadata to define models, relationships, authorization rules, and API behavior, then serves a unified supergraph.

Backend teams, platform teams, data engineers, and application developers use it for federated APIs, data aggregation, governance, and AI application data access. It is an API and data layer rather than a chatbot or general-purpose AI model. Hosting third-party and code connectors is billed separately, and Private DDN requires a sales engagement.

Features

  • Generate GraphQL APIs from metadata-defined models and relationships
  • Compose data from SQL, NoSQL, events, APIs, and code connectors
  • Apply field- and entity-level authorization policies
  • Provide filtering, pagination, sorting, and aggregations
  • Create immutable builds, preview APIs, and rollback deployments
  • Support federated collaboration and multi-repository CI/CD
  • View query plans, traces, and model and field usage statistics
  • Self-host with the v3 graphql-engine and build custom connectors

Use cases

  • Build a unified GraphQL API across databases and domain services
  • Expose governed data to applications, microservices, or AI agents
  • Federate independently developed subgraphs across multiple teams
  • Create preview environments and roll back API changes safely
  • Monitor API usage, access patterns, latency, and errors
  • Connect legacy APIs and code services to a common data layer
