The best Firebase Studio alternative for native mobile apps
Firebase Studio is Google's new AI app builder — but it's early-stage and tied to the Google ecosystem. Bilt is a proven platform for native mobile apps with live iOS previews, one-click publishing, and no vendor lock-in.
Proven mobile platform, not an early beta
What Bilt does that Firebase Studio can't
Purpose-built for native mobile
Firebase Studio is a general-purpose AI development environment. Bilt is purpose-built for native mobile apps — it understands iOS and Android patterns, navigation, and device APIs out of the box.
No Google ecosystem lock-in
Firebase Studio ties you to Firebase, Google Cloud, and Gemini. Bilt generates standard React Native code you can push to GitHub and deploy anywhere — your code, your choice.
In-browser iOS simulator
Preview your iOS app on a real simulator streamed to your browser — no Xcode or local setup needed. Firebase Studio's preview capabilities are limited and still evolving.
One-click App Store publishing
Publish directly to the Apple App Store and Google Play with automated build pipelines. Firebase Studio requires manual build and submission processes.
Voice input & real-time collaboration
We were doing the whole design-to-code pipeline manually. Bilt just... skips the middleman. Prompt goes in, native app comes out. It's genuinely weird how much faster everything moves now.
