Google Blog·medium signal

Google launched a full-stack vibe coding overhaul in AI Studio integrating its Antigravity coding agent (from the $2.4B Windsurf acqui-hire) and native Firebase backends. Developers can build complete full-stack apps including React/Next.js frontend, Firestore database, Firebase Auth, real-time multiplayer, and third-party API secret management — all from prompts. Google AI Studio is the only major full-stack vibe coding tool with a truly usable free tier, versus $20-25/month entry points elsewhere.
