Excalibase GraphQL

Instantly turns an existing PostgreSQL database into a GraphQL and REST API.

PlatformWebfreeglobal

Excalibase GraphQL is a free, open-source, Spring Boot-based tool that instantly turns an existing PostgreSQL database into a GraphQL API, with schema discovery, subscriptions, and type handling and no resolvers to write by hand. It also exposes REST access over the same discovered schema. It's aimed at developers who need a GraphQL API over an existing Postgres database without building and maintaining resolvers themselves.
