What is Firebase SQL Connect?

Firebase SQL Connect, formerly Firebase Data Connect, is a relational database service for mobile and web applications. It is built on Cloud SQL for PostgreSQL and provides secure schema, query and mutation management using GraphQL technology that integrates well with Firebase Authentication. Google renamed the product; according to the documentation, existing integrations continue to work normally.

Core Features

  • Fully managed PostgreSQL backend based on Cloud SQL
  • Automatic type-safe SDK generation for client applications
  • Vector search capabilities for AI-powered applications
  • Visual Studio Code extension for schema development
  • Local emulator for testing
  • Gemini in Firebase assistance for generating queries and mutations
  • End-user authentication via Firebase Authentication

Typical Use Cases

Relational app backend: Applications with structured, relationally modelled data use PostgreSQL without building a custom API layer.

Type-safe client access: SDKs generated from the GraphQL schema make data access type-safe in Kotlin, Swift, Dart and TypeScript.

AI features with vector search: Similarity searches are implemented directly in the application database.

Benefits

  • Relational data model with PostgreSQL instead of document-only modelling
  • Access control through Firebase Authentication at query and mutation level
  • Local emulator and VS Code extension for the development workflow
