It auto-generates typesafe SDKs for web, Android, and iOS, plus a new Node.js Admin SDK for trusted server-side execution. The release adds flexible schema migration modes (strict and compatible), security via Firebase Authentication, CEL-based authorization rules, and App Check attestation, expanded scalar types beyond standard GraphQL, schema-driven database indexes, vector search with Vertex AI integration for RAG flows, and detailed pricing for both the Data Connect service and the underlying Cloud SQL instance. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Firebase Data Connect and how does it work with PostgreSQL? Firebase Data Connect is a backend-as-a-service powered by a Cloud SQL for PostgreSQL database that lets developers define an app's data model through a GraphQL-based schema. It automatically generates secure endpoints and typesafe SDKs for web, Android, and iOS, eliminating the need to write custom resolvers as required in typical GraphQL services. _Developers evaluating backend-as-a-service options can follow Data Connect coverage on daily.dev._ ### Is Firebase Data Connect out of private preview yet? Yes, Firebase Data Connect moved from private preview to public preview, announced by the Firebase team. It was first introduced at Google I/O with a private preview requiring signup, and it now supports strict and compatible schema validation modes, CEL-based security rules, App Check attestation, and vector search integration with Vertex AI for RAG flows. _Teams tracking Firebase's roadmap can keep tabs on Data Connect updates through daily.dev._ ### How much does Firebase Data Connect cost to use? Data Connect bills two components separately: the Data Connect service and the Cloud SQL for PostgreSQL instance. Network egress is free up to 10 GiB per month with Premium Tier pricing beyond that, and operation counts are free up to 250,000 per month, then $4.00 per million. Cloud SQL includes a no-cost trial lasting through public preview, plus another 3 months at general availability. _Developers budgeting a backend-as-a-service migration can compare pricing details like these on daily.dev._ ## Similar posts on daily.dev - [Vibe-coded AI Studio apps with Firestore, Firebase, Cloud SQL](https://daily.dev/posts/vibe-coded-ai-studio-apps-with-firestore-firebase-cloud-sql-5faawqfxm) · Google Cloud · 0 upvotes · 0 comments --- Tags: [#backend](https://daily.dev/tags/backend), [#postgresql](https://daily.dev/tags/postgresql), [#graphql](https://daily.dev/tags/graphql), [#firebase](https://daily.dev/tags/firebase), [#vector-search](https://daily.dev/tags/vector-search) [View this post on daily.dev](https://daily.dev/posts/firebase-data-connect-now-in-public-preview--7somabhyu) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Firebase Data Connect: now in public preview!","url":"https://daily.dev/posts/firebase-data-connect-now-in-public-preview--7somabhyu","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/firebase-data-connect-now-in-public-preview--7somabhyu"},"datePublished":"2026-08-23T12:21:14.497Z","dateModified":"2026-08-23T12:45:02.398Z","description":"Firebase Data Connect, a backend-as-a-service built on Cloud SQL for PostgreSQL with a GraphQL-based schema, has moved from private preview to public preview....","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/81fd8d987ad3436e601aa3058b4e5d83?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/81fd8d987ad3436e601aa3058b4e5d83?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Firebase","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Firebase","logo":"https://media.daily.dev/image/upload/s--i395oqZH--/f_auto,q_auto/v1787487448/logos/firebase-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/firebase-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/firebase-data-connect-now-in-public-preview--7somabhyu","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"backend,postgresql,graphql,firebase,vector-search","timeRequired":"PT6M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Firebase","item":"https://daily.dev/sources/firebase-blog"},{"@type":"ListItem","position":3,"name":"Firebase Data Connect: now in public preview!"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/firebase-data-connect-now-in-public-preview--7somabhyu#faq","mainEntity":[{"@type":"Question","name":"What is Firebase Data Connect and how does it work with PostgreSQL?","acceptedAnswer":{"@type":"Answer","text":"Firebase Data Connect is a backend-as-a-service powered by a Cloud SQL for PostgreSQL database that lets developers define an app's data model through a GraphQL-based schema.
