nhost/constellation repository overview

Constellation is a GraphQL engine that turns relational databases into a role-based GraphQL API. It is a near-drop-in replacement for Hasura⁠ Community Edition: it speaks the same metadata format, generates Hasura-compatible schemas, and serves the same query/mutation/subscription surface — including remote schemas and cross-source relationships.
