Announced at today's I/O keynote, Google AI Studio's new coding agent (built on the Antigravity agent harness) proactively detects when your app needs data storage and user identity from prompt cues alone, then auto-provisions Firestore, Firebase Authentication with Google Sign-In, generates Firestore sync code, and drafts/deploys Security Rules based on app logic — all with one 'Enable Firebase' click. This eliminates the backend setup ceremony that typically delays prototype-to-production transitions for AI-built apps.
