Instant GraphQL and REST API engine connecting directly to databases with fine-grained authorization and automated caching.

About Hasura

Hasura is an industry-leading data access platform that automatically generates instant, production-grade GraphQL and REST APIs directly from connected databases and external data sources. By eliminating the necessity of writing repetitive CRUD API boilerplate code, Hasura enables engineering teams to ship data-driven web and mobile applications in a fraction of the traditional development time.

The platform integrates a sophisticated fine-grained authorization engine that enforces dynamic, role-based access control rules down to individual database rows and columns based on incoming session headers. Hasura Data Delivery Network (DDN) introduces modular data connector architecture, sub-millisecond query compilation, and distributed edge caching across heterogeneous data backends.

Hasura is available as an open-source Docker engine for self-hosted infrastructure, as well as Hasura Cloud, a fully managed global SaaS platform. It provides a free cloud tier for developers alongside scalable team and enterprise tiers equipped with high availability, query auditing, and SSO.
