Firebase Studio Is Being Retired: What to Migrate To in 2026

Firebase Studio Is Being Retired

Firebase Studio (formerly Project IDX) was Google's free cloud IDE with Gemini-powered app prototyping. It is now on its way out.

What Google has announced:

• New workspace creation and signups disabled on 2026-06-22. If you don't already have a workspace, you can't start one.
• Sunset on 2027-03-22. Existing workspaces stop working after that date.
• Migrate to Google AI Studio or Antigravity. Those are the successors Google points existing users at.

The other reasons users were already leaving:

• Google ecosystem lock-in: Deep ties to Firebase, Cloud Run, and GCP. If you're not on Google Cloud, the integrations don't help.
• Limited AI generation: App Prototyping agent handles web apps only. Less capable than purpose-built AI app builders for complex applications.
• No automatic error recovery: When Gemini-generated code has bugs, you fix them manually.

1. GenMB - Best Overall Alternative

GenMB is an AI app builder with deployment, automatic error fixing, and 80 integrations. It is actively developed, not on a sunset schedule.

GenMB vs Firebase Studio:

Where GenMB wins: Production readiness, Code Healer, Visual Editor, 80 integrations that work across any hosting provider (not just Google Cloud), and a stable product that won't be deprecated.

Where Firebase Studio still helps: if you already have a workspace and your stack is Firebase/GCP, the native integration is seamless until the 2027-03-22 sunset. The Code IDE supports importing existing repos and working with any language, which makes getting your code out straightforward.

Best for: Users who need a reliable, production-ready AI app builder.

2. Bolt.new - Best for Speed

Bolt's in-browser execution makes it the fastest from prompt to preview among production-ready tools.

Strengths over Firebase Studio:

• Production-ready with established track record
• Instant in-browser previews via WebContainers
• Built-in Stripe and Supabase (not limited to Firebase services)
• Active community with templates

Limitations:

• Token-based pricing (Pro $25/mo for 10M tokens)
• No automatic error fixing

Best for: Users who want production-ready speed without Firebase dependencies.

3. Replit - Best Cloud IDE Alternative

If you like Firebase Studio's cloud IDE approach but want something production-ready, Replit is the established option.

Strengths over Firebase Studio:

• Production-ready (years of stability)
• Multi-language support and React Native for mobile
• Collaborative editing
• Replit Agent 4 for AI generation

Limitations:

• Expensive: Core $20/mo, Pro $100/mo (after Feb 2026 pricing overhaul)
• AI generation less focused than purpose-built app builders

Best for: Developers who want a stable cloud IDE with AI assistance and multi-language support.

4. Lovable - Best for Non-Technical Users

If Firebase Studio's App Prototyping agent was your entry point to AI app building, Lovable is a more polished, dedicated experience.

Strengths over Firebase Studio:

• Purpose-built for prompt-to-app (not an IDE with AI bolted on)
• Higher quality React output with strong visual polish
• Supabase backend integration
• Stable product with SLA

Limitations:

• $25/mo Pro (Firebase Studio had no subscription price, but is being retired)
• React only
• No code editing
• No automatic error fixing

Best for: Non-developers who want a polished, stable AI app builder.

5. GitHub Spark - Best for GitHub Users

GitHub Spark offers managed runtime (hosting, data, AI inference) within the GitHub ecosystem. Also in preview, but backed by GitHub/Microsoft.

Strengths over Firebase Studio:

• GitHub ecosystem integration (repos, Copilot, Actions)
• Managed runtime includes hosting and data storage
• Claude Sonnet 4 for generation (vs Gemini in Firebase Studio)
• Code editing + AI prompts together

Limitations:

• Requires Copilot Pro+ ($39/mo)
• TypeScript + React only
• Also in public preview
• 4 premium requests per prompt (can add up)

Best for: Teams already on GitHub Copilot Pro+ who want app generation within their existing workflow.

The Production-Readiness Question

This matters more than features:

Building anything you care about on a preview product is risky. The features may change, the free tier may evaporate, or the product may be deprecated entirely.

Our Recommendation

Firebase Studio is closed to new users and shuts down on 2027-03-22, so the question is where to go next, not whether to start there. Inside Google, that means Google AI Studio or Antigravity. If you want to keep shipping deployed full-stack apps, GenMB at $19/month gives you AI app building with Code Healer, Visual Editor, and 80 integrations that work across any stack, not just Google Cloud.

If you already have a Firebase Studio workspace, export your code through GitHub before the sunset date and rebuild wherever you land.
