A Firebase Studio alternative that signs your code: SPOE vs Firebase StudioFirebase Studio closes on 22 March 2027. Here is how to keep what you built, what SPOE does differently, and where else may suit you better.SPOE

Free to start. 250 credits when you sign up, your first live preview free, and a daily top-up to 30, no card. A build on the default models costs about 10 to 30 credits.

Paying. A plan from A$19 a month for 5,000 credits every month (cheaper by the year), or a credit pack bought once, from A$19 for 4,000 credits. Credits never expire, and each model is used at its own price.

Your code. Export a ZIP, or link a GitHub repo once: every version lands there as a commit, and commits made in the repo come back in.

Export, for good. Your first payment of any size unlocks export permanently, whether or not you ever pay again. Locked or not, the code is always visible and copyable in the editor.

Proof. Every export carries an Ed25519-signed provenance manifest and the verifier that checks it, offline or at spoe.ai/verify, in your browser.

Runs without us. An export is a Next.js, Fastify and Postgres project, or a plain HTML website, that starts with docker compose up and has no SPOE dependency inside. CI proves that on every commit.

Safety. Every change is reviewed by a second model from a different model family before it lands. A flagged change waits for you.

Privacy. Models run on Venice's private inference, which keeps no copy of prompts or outputs. Chats, bots and images stay in your browser.

Hosting. Publish to <name>.spoe.dev, or to a domain of your own with automatic HTTPS.

Firebase StudioFirebase Studio closes on 22 March 2027. After that, every workspace left in it is deleted and cannot be recovered. (source)

New users. Sign-ups and new workspaces were switched off on 22 June 2026. Existing workspaces keep working until the close. (source)

Keeping your code. Zip and Download from Move now, an export to GitHub, a move to Google AI Studio, or npx firebase-tools@latest studio:export for Google Antigravity. (source)

After the close. Firestore, Authentication and App Hosting carry on outside Firebase Studio. (source)

Google's own tools may suit you better if you want to stay with Google: Antigravity for working in code, AI Studio for building in the browser, with Firestore and Authentication carrying on as they are.Moving to SPOEDownload your code first, while Firebase Studio still lets you: it is yours whatever you do next. Then describe the app to SPOE and it is built as a Next.js, Fastify and Postgres project you hold, signed, that starts with docker compose up. If the app is live and you can add a tag to its pages, Bring your site copies its pages, styles and pictures into a SPOE project to keep building.Read from Firebase Studio's own pages on 2026-10-15.
