Google killed Firebase Studio on March 19, 2026 — less than a year after its launch. The full-stack AI workspace, unveiled at Google Cloud Next in April 2025, will shut down completely on March 22, 2027. Migration tools started rolling out the same day, pointing users toward Google AI Studio or Antigravity. That is an unusually short product lifespan, even by Google standards. The question nobody should be asking is whether Firebase Studio was good. The question is what Google is building instead.
The replacement stack is more interesting than the sunset. Google AI Studio, the browser-based prototyping tool, got a significant upgrade that day: a new coding agent called Antigravity, built from the agent harness Google licensed — and the team it hired — after paying $2.4 billion in license fees and hiring key Windsurf staff in July 2025. Reuters described the deal as license fees plus a hiring arrangement, not an acquisition. Google wasn't buying a landing page.
What makes Antigravity distinct, and what the Firebase Studio announcement quietly buried, is that it runs models from three families: Google's own Gemini 3.1 Pro and Gemini 3 Flash, Anthropic's Claude Sonnet 4.6 and Claude Opus 4.6, and GPT-OSS-120B. The official Firebase migration page frames it as a cross-model IDE — not a chatbot wrapper that calls one API, but an agent harness architected to route tasks to different models depending on what the job demands. Google's own migration documentation explicitly calls out Claude and GPT-OSS as first-class alternatives to Gemini, which is notable for a company that usually competes on model lock-in. Claude Code has been widely noted in industry coverage as pulling enterprise customers away from both Google and OpenAI — Google's answer is to offer Claude as a first-class citizen in its own IDE.
The blog post from Ammaar Reshi and Kat Kampf, product leads at Google AI Studio, frames the upgrade around speed: the agent automatically detects when an app needs data storage or authentication and offers Firestore and Firebase Authentication setup with one click. It auto-installs modern web tools like Framer Motion and Shadcn for UI components. Apps built in AI Studio will be able to deploy to Antigravity — Google says that transfer is coming soon. Sessions persist across browser closes. Multiplayer apps are in scope. Hundreds of thousands of apps have already been built with the internal version, per Google's blog.
There is a competing frame that matters. Aihola's review of the Antigravity integration flagged early stability issues — anything beyond roughly a thousand lines of code reportedly caused problems. The Google developer forum has threads from Ultra subscribers describing seven-day quota lockouts and broken workspaces. The agent harness exists; whether it reliably handles production workloads is a different question.
This is where the FindSkill comparison cuts through the marketing: "Google AI Studio gets you to demo day faster. Claude Code gets you to production faster." That is a clean distillation of the tradeoff Google is making — optimize for the moment an idea becomes a shareable prototype, not for the moment it becomes a business. Firebase Studio was trying to solve the full stack. AI Studio with Antigravity is trying to solve the demo. These are genuinely different products with different failure modes.
The durable pattern here — and this is worth bookmarking for any Big Tech product kill — is that when a company sunsets something quickly, the announcement is about what went away. The real story is the migration path, which tells you what they're betting on. Firebase Studio's death sentence is a referral to Antigravity, and Antigravity is explicitly a cross-model agentic IDE with Claude and GPT-OSS alongside Gemini. That is not a company protecting its own model ecosystem. That is a company responding to enterprise pressure by becoming model-agnostic at the tooling layer while continuing to compete on the model layer. The infrastructure play is the story; the product kill is just the news peg.
The sunset timeline gives Firebase Studio users roughly a year to migrate — new workspace creation is disabled June 22, 2026, and everything is deleted March 22, 2027. For teams already on Firebase Studio, the clock is not short. For teams evaluating AI coding tools, the question is whether the browser-based prototype path through AI Studio is worth starting now, or whether the production reliability gap between AI Studio and Claude Code is still wide enough to justify going straight to the latter.
Google says it's working on one-click migration from AI Studio to Antigravity, and Workspace integrations with Drive and Sheets are on the roadmap. Whether those land before Firebase Studio's data deletion date is the kind of detail that matters when you're deciding whether to bet your workflow on it.
