Conclusion
From a connected database, the GraphQL Engine generates a full featured data API automatically, with no handlers, schemas or resolvers to write. Supported sources include Postgres and compatible databases, Microsoft SQL Server, Google BigQuery, Snowflake, MySQL and MongoDB. Access is governed by fine-grained, role-based permissions at the field and row level, and live updates arrive through GraphQL subscriptions. Event triggers can invoke serverless functions or webhooks on database changes, and REST APIs can be combined with other sources into a single GraphQL API.
Backend, full-stack and mobile app developers are the main audience, along with enterprises needing scalable APIs. The company now also builds the Data Delivery Network (DDN) and PromptQL, its product for accurate AI on business data. DDN runs self-hosted or as a fully-managed cloud product, with a free tier for individual developers and paid tiers billed per active model.
