A Firebase Studio alternative that ships production apps.
Google is sunsetting Firebase Studio: new signups closed on June 22, 2026, and the platform shuts down on March 22, 2027. If you’re reading this, you’re probably choosing what comes next. Here’s an honest look at what Firebase Studio did well, what Google recommends, and where opix fits.

What Firebase Studio did well
Firebase Studio was a genuinely capable idea: a free, fully browser-based development environment on a Google Cloud VM, pairing a real Code OSS editor with the Gemini-powered App Prototyping agent. Describe an app and it generated a Next.js/React project with Cloud Firestore and Firebase Authentication provisioned automatically — Google’s infrastructure, Google’s models (Gemini 3.0 Flash was rolling out in early 2026), and up to 30 workspaces with a paid Google Developer Program Premium subscription. For prototyping inside the Firebase ecosystem, it was hard to beat on price: the builder itself cost nothing.
The timeline is the catch. Launched in preview in April 2025, it never left preview; Google announced the sunset on March 19, 2026 — less than a year after launch — disabled new signups and workspaces on June 22, 2026, and will delete all remaining data on March 22, 2027. Google’s official migration paths are Google AI Studio (prompt-to-app with Firestore and Firebase Auth integrated) and Antigravity, its local agent-first IDE. Apps already deployed keep running, and core Firebase services are unaffected — the builder is what’s going away.

| Firebase Studio | ● opix | |
|---|---|---|
| Status | Sunset: signups and new workspaces closed June 22, 2026; shutdown and data deletion March 22, 2027 | Generally available and in active development |
| Price | Free during preview: 3 workspaces (10 with Google Developer Program, 30 with GDP Premium) | Free welcome credits, no card; Starter $29/mo with 120 credits |
| Purpose | Prototyping: a cloud IDE plus the App Prototyping agent, officially web-apps-only | Production web apps: database, auth, payments and publishing in one build |
| Backend | Auto-provisioned Cloud Firestore + Firebase Auth on Google Cloud | Dedicated Neon Postgres per app plus generated auth — standard and portable |
| Deployment | Firebase App Hosting; requires a Cloud Billing account on the pay-as-you-go Blaze plan | Publishing included; custom domains on Pro; hard spend caps you set |
| Leaving | Sanctioned exits are Google AI Studio and Antigravity; zip export (agent chat history not included) | GitHub export + eject to any host — standard Next.js, standard Postgres |
| Company | Google (United States) | Switzerland — CH/EU data posture, DPA available |
Where opix stakes its difference
Built for the day after the demo
Every build is type-checked and smoke-tested in the sandbox — 94% of first builds compile clean — then published with a real domain. Shipping is the default path, not the upgrade.
A backend that can leave
Firestore and Firebase Auth are excellent — on Google Cloud. Your opix app runs on its own Postgres with auth in the codebase, portable to any host you choose.
Caps instead of billing anxiety
Deploying from Firebase Studio meant pay-as-you-go Blaze billing. opix builds are metered credits with a live meter, hard caps you set, and failures billed at zero.
No ecosystem bet
A sunset is what platform risk looks like. opix generates standard Next.js on standard Postgres precisely so your app never depends on our roadmap — export and eject are supported features.
How to choose
If you’re invested in the Firebase ecosystem and want to stay with Google, take the official paths: Google AI Studio now integrates Firestore and Firebase Authentication for prompt-to-app building, Antigravity covers agent-first local development, both are first-party, and your deployed Firebase services keep running untouched. That’s the low-friction move, and for Gemini-centric workflows it’s a sensible one.
Choose opix if the migration is a chance to own the whole thing: a production Next.js app with its own Postgres, costs you can see and cap, failures that bill nothing, and an exit that’s a feature rather than a migration doc. Honest trade: Firebase Studio was free and opix isn’t past the welcome credits — it’s priced for shipping products, not for parking prototypes.
Asked before you asked.
Is Firebase Studio shutting down?+
Yes. Google announced the sunset on March 19, 2026; new signups and workspace creation have been disabled since June 22, 2026; and the platform shuts down on March 22, 2027, when remaining data is permanently deleted. Apps already deployed to Firebase keep running, and core services like Firestore, Auth and App Hosting are not affected.
What is Firebase Studio?+
It was Google’s agentic, browser-based development environment — the successor to Project IDX — combining a Code OSS cloud IDE with the Gemini-powered App Prototyping agent, which generated Next.js/React web apps with Firestore and Firebase Auth provisioned automatically. It launched in preview in April 2025 and never left preview before the sunset was announced.
What does Google recommend migrating to?+
Google’s official paths are Google AI Studio, whose build mode now integrates Cloud Firestore and Firebase Authentication, and Google Antigravity, a local agent-first IDE. Workspaces export as a zip, though agent chat history isn’t included. If you’d rather leave the ecosystem entirely, that’s where opix comes in — production Next.js on a Postgres you own.
Was Firebase Studio free?+
The builder was free during its preview — 3 workspaces per user, up to 30 with a Google Developer Program Premium subscription. Real deployments weren’t: publishing through Firebase App Hosting required a Cloud Billing account on the pay-as-you-go Blaze plan. Either way, new users haven’t been able to sign up since June 22, 2026.
Does opix use Firebase?+
No. Every opix app gets its own dedicated Postgres database (on Neon) with auth generated into the codebase — no Firestore, no proprietary datastore, no ecosystem dependency. The result is a standard Next.js repo you can export to GitHub or eject to any host at any time.
Can I import my Firebase Studio app into opix?+
There’s no automated importer, and moving data from Firestore to Postgres is a real task — we won’t pretend otherwise. The practical path: describe the app and paste screenshots, let opix rebuild it on Next.js with its own database, and use your exported zip as the reference for anything subtle. For most prototypes that’s an afternoon.
Rebuild it somewhere it can stay.
Describe your prototype once — opix builds it as a real Next.js app on a database you own. Welcome credits free, failures $0.
