Hasura

Hasura connects to your existing database and instantly generates a GraphQL API with automatic query resolvers, mutations, and subscriptions. It requires no backend code to write and includes role-based access control, request validation, and webhook support for custom business logic. You can connect PostgreSQL, MySQL, SQL Server, Big Query, or other databases without any glue code.

Best for teams with existing databases who need APIs quickly without building backend services. Developers appreciate Hasura for cutting weeks of API development into hours, while it lets non-technical teams define permissions and workflows visually. It's ideal when your bottleneck is shipping frontends that need backend APIs, not designing data models from scratch.
