Google is consolidating its AI development tools by shutting down Firebase Studio and directing developers toward two flagship platforms: Google Antigravity for code-first, agent-driven work, and Google AI Studio for rapid browser-based prototyping. The Firebase Studio sunset, announced on March 19, 2026, gives developers a one-year transition period to migrate their projects before the platform closes permanently on March 22, 2027.

Firebase Studio launched as a preview to explore the future of AI-driven, full-stack development. Based on developer feedback, Google decided to streamline its offerings by integrating the lessons learned from Firebase Studio into more specialized tools. The core Firebase services, including Cloud Firestore, Authentication, and App Hosting, will continue to function normally and are not affected by the sunset.

What Is Google Antigravity and How Does It Work?

Google Antigravity is an agent-first integrated development environment (IDE), a fork of Visual Studio Code that launched on November 18, 2025, alongside Gemini 3. Unlike traditional code assistants that autocomplete your next line, Antigravity hands an autonomous agent a high-level goal and lets it plan, write, run, and verify the work across your editor, terminal, and browser.

The platform operates across three surfaces simultaneously: your code editor to read and write files, your terminal to install dependencies and run builds, and a browser to open Chrome and verify that the user interface actually works. This browser verification loop is what genuinely separates Antigravity from older coding assistants. The agent does not simply claim the code compiles; it opens the page, clicks through it, and brings back screenshots as evidence.

Google calls this an "agent-first" experience, which fundamentally shifts your role from typing every function to reviewing what an agent produced and deciding whether to accept it. The platform is currently free during its public preview phase, and it supports multiple AI models, including Gemini 3 Pro, Claude Sonnet 4.5, Claude Opus 4.5, and OpenAI open-source variants.

How to Migrate Your Firebase Studio Project to Antigravity?

• Export Your Project: Click the "Move now" button at the top of your Firebase Studio workspace, then follow the export method by either clicking the Zip and Download button or running the Firebase Studio: Zip and Download command from the command palette.
• Set Up Your Local Environment: Ensure you have the Antigravity IDE, Node.js version 20 or higher, and Firebase CLI version 15.10.0 or higher installed locally on your machine.
• Open and Transform: Extract the exported folder locally and open it in the Antigravity IDE, then use the Antigravity agent with the prompt "@fbs-to-agy-export" to autonomously handle the project transformation.
• Follow Agent Guidance: The Antigravity agent will begin the migration process and request your assistance along the way; follow the agent's guidance to complete the migration successfully.

Google recommends selecting the Gemini Flash model during migration to optimize your workflow and conserve tokens, as it is designed for speed and efficiency in high-volume transformation tasks like file conversion.

Who Should Migrate to Antigravity Versus Google AI Studio?

Google provides clear guidance on which platform suits different development workflows. Developers should choose Antigravity if they prefer working in an agent-first desktop environment with deeper control over their codebase, created their app using a built-in template or imported repository, primarily used the Code View environment, want direct access to state-of-the-art agentic AI development capabilities with support for different models like Claude and GPT-OSS, or started in Prototyper mode but added significant features requiring a local environment.

Conversely, developers should migrate to Google AI Studio if they prefer a web-based experience ideal for multi-device workflows, created their app using the App Prototyping agent and value rapid prototyping, or want the fastest path from prompt to full-stack production app. Google AI Studio offers direct integration with Cloud Firestore and Firebase Authentication, providing the fastest path from prompt to production.

What Are the Key Capabilities That Make Antigravity Different?

• Terminal Execution: Agents run shell commands, install dependencies, and run builds directly rather than as suggestions you paste into your terminal manually.
• Browser Verification: Browser subagents launch Chrome, click through the user interface like a real user, and bring back screenshots as proof that the application actually works.
• Self-Validation: An agent writes tests, runs them, identifies failures, and iterates before presenting the result for human review.
• Artifacts, Not Logs: Task Lists, Implementation Plans, and Walkthroughs capture intent and proof, allowing developers to verify work in minutes rather than reading raw tool calls.
• Reusable Rules: Developers can save a workflow, such as "generate-unit-tests," and re-apply it so agents follow consistent conventions every time.
• Parallel Agents: Mission Control dispatches multiple agents on separate tasks simultaneously, with a shared multiplayer whiteboard for planning.

The term Google uses for this front-end experience is "vibe coding," which is shorthand for describing intent at a high level, such as "build a dashboard that responds smoothly," rather than spelling out every function signature. This approach works well for greenfield user interface design and scaffolding but works less well when requirements are precise and unforgiving.

What Is the Timeline for Firebase Studio's Shutdown?

Google has established a clear migration timeline to give developers ample time to transition their projects. On March 19, 2026, Google announced the sunset and migration tools began rolling out to Firebase Studio users. On June 22, 2026, new workspace creation will be disabled, though developers can continue to work in and migrate existing workspaces. Finally, on March 22, 2027, Firebase Studio will shut down completely, and all remaining data will be permanently deleted and cannot be recovered.

For developers who previously published their apps through Firebase Studio and want to keep their existing URLs, Google provides detailed guidance on securing API keys and using GitHub Sync to maintain continuity. Alternatively, developers who prefer a one-click publishing experience can move to Cloud Run and publish their apps to a new URL.

Google emphasizes that its commitment to the Firebase ecosystem remains strong. By integrating agentic capabilities directly into flagship AI platforms, the company is ensuring that Firebase continues to provide a seamless, reliable backend for AI-driven development. Core Firebase services such as Cloud Firestore, Authentication, and App Hosting will continue to work outside of Firebase Studio and are not affected by the sunset.
