Firebase Data Connect rebrands to Firebase SQL Connect with Realtime PostgreSQL and native SQL support

At Google Cloud Next '26, Firebase announced that Firebase Data Connect has evolved into Firebase SQL Connect, adding realtime syncing (the #1 requested Firebase UserVoice feature), offline cache, native SQL query support, custom resolvers, and a no-cost trial. The @refresh directive pushes query result changes to clients in real time. Native SQL support allows raw SQL queries and mutations with access to PostgreSQL extensions like PostGIS. Custom Resolvers (experimental) let developers extend SQL Connect to integrate external APIs, Cloud Storage, or BigQuery via Cloud Functions. The platform now supports direct DML operations, CTEs, window functions, and complex aggregations. Client SDKs are available for Kotlin Android, iOS, Flutter, and web.
