Riff builds web apps. Bilt builds native mobile apps
Riff generates web applications with AI. But web apps can't access native device features or be published as real App Store apps. Bilt generates true native iOS and Android apps from prompts.
The mobile gap
Riff is a fast AI web app generator. But when you need a real app on the App Store with native performance and device APIs, you need a purpose-built mobile tool.

- Browser-based workflow
What Bilt adds

Feature comparison
Built for native mobile
Chat-based app creation
Describe your app in natural language and Bilt generates a full React Native codebase. Same prompt-based workflow as Riff, but for native mobile apps.
iOS simulator in your browser
Preview your app on a real iOS simulator streamed to your browser. No Mac or Xcode required. Test gestures, navigation, and native behavior.
One-click App Store publishing
Publish to the Apple App Store and Google Play with automated build pipelines. Go from prompt to published in minutes, not weeks.
Instant backend & APIs
Spin up databases, authentication, and APIs automatically. Your app gets a production-ready backend without separate tooling.
“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.”
