Firebase Studio is Google's agentic, browser-based development environment for building full-stack AI apps. It unifies the former Project IDX with Gemini-powered AI agents and assistance. Developers can either describe an app in natural language to the App Prototyping agent (Prototyper) and have it generated and deployed without writing code, or work in a Code OSS-based IDE (Coding with full control) with Gemini for code completion, generation, testing, and tool-running. The product is aimed at developers building web, mobile, and backend apps on Firebase and Google Cloud, and at less-technical users who want to prototype from a prompt. It supports a wide range of stacks (Next.js, React, Angular, Vue, Flutter, Go, Java, .NET, Node.js, Python) plus imports from GitHub, GitLab, and Bitbucket, and deploys to Firebase App Hosting and Firebase Hosting. Google has announced that Firebase Studio will be sunset on March 22, 2027, directing users to migrate to Google AI Studio or Google Antigravity; apps already deployed are stated to keep running after that date.

What it can do

  • Prototype apps from natural language (App Prototyping agent)

    Supervised

    The Prototyper agent generates a full-stack web app from a multimodal prompt (text, images, drawings) using Gemini, then lets the user iterate, test, and deploy without writing code.

    source

  • Gemini-assisted coding in a cloud IDE

    Copilot

    In the Code OSS-based 'Coding with full control' IDE, Gemini provides workspace-aware code completion, generation, testing, tool-running, and documentation.

    source

  • Agent modes for multi-file changes

    Supervised

    Three Gemini interaction modes: Ask (chat/plan only), Agent (proposes changes the user approves one by one), and Agent (Auto-run), which can autonomously reason and generate or modify apps across files, with restrictions on file deletion and terminal commands.

    source

  • Model Context Protocol (MCP) and Gemini CLI support

    Supervised

    Supports adding MCP servers (for example the Firebase MCP server to explore Firestore data, or Context7 for library guidance) and integrates the Gemini CLI for terminal-based AI assistance inside the workspace.

    source

  • Import and deploy projects

    Supervised

    Imports existing codebases from GitHub, GitLab, Bitbucket, or local machine, configures environments via Nix, and deploys to Firebase App Hosting and Firebase Hosting with the Local Emulator Suite for testing.

    source

Strengths

  • +Free during the preview period, with no seat fees or credit card required to start (3 workspaces, more for Google Developer Program members)
  • +Two real entry points: prompt-to-app prototyping and a full Code OSS IDE, both with Gemini assistance
  • +Tight Firebase and Google Cloud integration, broad framework support, MCP and Gemini CLI extensibility

Limitations

  • −Announced sunset on March 22, 2027, with migration pushed to Google AI Studio or Google Antigravity, a real continuity risk
  • −Still in preview with no SLA or deprecation policy and evolving features
  • −Agent autonomy is bounded: changes need approval and even Auto-run mode restricts file deletion and terminal commands

Overview

Firebase Studio is Google's agentic, cloud-based development environment for building full-stack AI apps. It unifies the former Project IDX with Gemini-powered AI agents in a browser workspace. It launched in preview in April 2025 and remains in preview as of this review.

What it does

There are two ways to build. The App Prototyping agent (Prototyper) turns a multimodal prompt into a working full-stack web app you can iterate on and deploy without writing code. 'Coding with full control' is a Code OSS-based IDE where Gemini provides workspace-aware completion, generation, testing, and tool-running. Gemini offers three interaction modes: Ask (plan/chat only), Agent (you approve each proposed change), and Agent (Auto-run), which can reason and generate or modify apps across files with guardrails on file deletion and terminal commands. It is powered by Gemini (2.5 at the agentic-features launch, later 3.x models).

Integrations & setup

Imports projects from GitHub, GitLab, Bitbucket, or local machine, with Nix-based environment customization and broad framework support (Next.js, React, Angular, Vue, Flutter, Go, Java, .NET, Node.js, Python). It supports Model Context Protocol (MCP) servers, including the Firebase MCP server, and integrates the Gemini CLI. Deploys to Firebase App Hosting and Firebase Hosting, with the Local Emulator Suite for Authentication, Cloud Functions, Firestore, and Cloud Storage.

Pricing

Free during preview: 3 workspaces with no seat fees or credit card. Google Developer Program members get 10 (Standard) or 30 (Premium) workspaces, and Premium adds increased Gemini quota for the App Prototyping agent. Some deployment integrations may require a Cloud Billing account.

Best for / not for

Best for developers in the Firebase and Google Cloud ecosystem and for quick prompt-to-app prototyping. Less suited to teams that need long-term platform stability, given the announced March 2027 sunset, or to fully unattended automation, since agent actions are bounded and approval-gated by default.

Alternatives

Replit Agent, Bolt.new, Lovable, and v0 cover prompt-to-app building; for in-IDE coding assistance, GitHub Copilot is a closer comparison. Google's own migration path points to Google AI Studio and Google Antigravity.

FAQ

Is Firebase Studio free?+

Access is free during the preview, with 3 workspaces at no cost and no credit card required. Google Developer Program members get more (Standard 10, Premium 30). Some integrations like Firebase App Hosting may require a Cloud Billing account.

Is Firebase Studio being shut down?+

Google has announced a sunset date of March 22, 2027, and recommends migrating to Google AI Studio or Google Antigravity. Apps already deployed are stated to continue running after that date.

Is Firebase Studio fully autonomous?+

No. Its default Agent mode proposes changes the user approves one by one. An Agent (Auto-run) mode can act across multiple files autonomously, but with restrictions on file deletion and terminal commands, so it is best treated as a supervised agent.
