Google Cloud launched a Starter Tier within Google AI Studio that lets you deploy a prototype to a live URL using Cloud Run, Firestore, Cloud SQL for PostgreSQL Developer edition, and Firebase Authentication without providing a payment method or creating a billing account.

Google provisions a fully managed project behind the scenes—region selection, API enablement, and security policies are handled for you.

The pre-wired stack is intentionally limited: you get a single region, a maximum of two active Cloud Run apps, a shared Firestore quota (1 GiB storage, 10 GiB egress/month, 40k writes/day, 50k reads/day, 50k real-time updates/day), and Cloud SQL for up to two apps.

The console is simplified, not the full Google Cloud console; if you navigate to an unsupported product (BigQuery, Pub/Sub), you’re prompted to start a Free Trial.

Upgrade is an in-place operation from the Projects page in Google AI Studio—no migration, no data export, no DNS cutover. Adding a payment method keeps your services running and your .run.

app URLs unchanged.

A caveat: Firestore databases created by the agent stay in a shared-quota group even after you add billing; you need to upgrade the database from the Firebase console to get standard billing.

The Starter Tier is for prototyping with AI Studio; if you need a 90-day evaluation period or products like GKE or BigQuery, the Free Trial is the recommended alternative.
