AI Studio unlocks full-stack vibe coding with Cloud Run, Firebase, and Cloud SQL, no credit card required

At Google I/O 2026, Google announced expanded integration between AI Studio and Google Cloud, allowing new users to deploy up to two full-stack applications on the Starter Tier without a billing account or credit card. The update adds Cloud SQL for PostgreSQL as a relational database option alongside Firestore, with an AI agent that can automatically infer and provision the appropriate database, authentication via Firebase Auth, and deployment to Cloud Run. Users can build and launch apps entirely through natural language prompts, with the backend scaling to zero when not in use to minimize costs.

At Google I/O 2026, we announced updates to the integration between Google AI Studio and Google Cloud: New users can deploy up to two full-stack applications to the Google Cloud Starter Tier, no billing account required An expanded choice of databases: Firestore for non-relational data, and Cloud SQL as a new relational database option Tight integration with Google Workspace tools like Sheets, Calendar, and Gmail using Firebase Auth as the single user login flow This is an update to the integration we announced in March, which included support for vibe-coded full-stack app deployments from AI Studio powered by Cloud Run, Firestore, and Firebase Auth. With this expanded integration, you can use AI Studio to build a broader set of applications, using either a relational database with Cloud SQL or a non-relational database with Firestore. You don’t even need to specify a database — the AI agent can infer the right database for your app or feature. Get started today in AI Studio at no cost with Cloud Run, Cloud SQL for PostgreSQL coming next month , Firestore, and Firebase Auth for Starter Tier. You can build applications in AI Studio and deploy your prototypes directly to Cloud Run, authenticate via Firebase Auth, and store your data in a Firestore or Cloud SQL database. No credit card, no Google Cloud account, no friction — just prompt and launch. If you don’t have an account, AI Studio uses the Google Cloud Starter Tier to create resources for you. You can deploy up to two full-stack apps. If you outgrow the limits of the Starter Tier, you can upgrade to a standard Google Cloud project with a billing account. All your resources will be transferred to your billable Google Cloud project, so that your application can scale as it grows. We’re introducing an intelligent, automated data foundation that makes it easy for developers to focus on their applications, not their infrastructure. AI Studio integration with Cloud SQL includes: An instant on-ramp: Go from prompt to a fully-deployed PostgreSQL database rapidly with instant provisioning. Zero-cost startup: Try Cloud SQL for the Google Cloud Starter Tier at no cost, without needing a credit card or Google Cloud account. Flexible cost control: The AI agent uses a new Cloud SQL for PostgreSQL developer edition, which enables the backend to scale to zero automatically, so you only pay while you’re using the app. Agent-driven experience: To update your application, enter new prompts and the AI Agent automatically creates the schema and executes SQL statements in the database. When you’re building an app in AI Studio, the agent proactively detects if you need data storage and authentication based on your prompt, and offers to set up a database and user authentication. For apps that benefit from a document database, the agent shows a card to turn on Firestore and Firebase Authentication with your approval. By clicking “Enable Firebase,” the agent automatically: Provisions Firestore, enables authentication, and connects your app to the database Creates your web app’s sign-in page and configures authentication with Google Sign In Generates the Firestore code in your app so you can sync data across sessions and devices Drafts and deploys Firestore Security Rules based on your app’s logic but you should always double-check these rules before sharing or deploying your app With Firebase Auth, you can: Check out more details on the What’s New from Firebase at Google I/O blog. Going from idea to app is now a reality. You can build a full-stack application at no cost using the following steps: Log into AI Studio: Access the platform to begin your project. Build with prompts: Start building your application using natural language prompts. For example, “Build an expense tracker app.” Enable the database: Prompt “Add a database” and AI Studio intelligently provisions a database through an "Enable" widget. You can explicitly ask for a relational database if you’d like to make your preference clear. Set up the system: Select “Enable” and agree to the terms. Start sharing: Deploy and share the application through the “Publish” button. Get started today in AI Studio to turn your ideas into live applications in seconds.
