Firebase Studio builds web apps. Bilt builds native mobile apps
Google's Firebase Studio (formerly Project IDX) is a cloud-based IDE for web and Firebase development. But it doesn't generate native mobile apps from prompts. Bilt does — with one-click App Store publishing.
The mobile gap
Firebase Studio is a powerful cloud IDE backed by Google. But it's a development environment, not a mobile app generator. Bilt generates complete native apps from prompts.

Feature comparison
Built for native mobile
Prompt to complete app
Firebase Studio helps you code. Bilt takes a prompt and generates an entire working mobile app — screens, navigation, backend, and all.
iOS simulator in your browser
Preview your app on a real iOS simulator streamed to your browser. No Xcode or local setup required.
One-click App Store publishing
Skip the complexity of signing certificates, provisioning profiles, and manual builds. Bilt automates everything.
Instant backend & APIs
Bilt generates databases, authentication, and APIs alongside your mobile app automatically. No Firebase configuration needed.
“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.”
