GenVibe is an AI React Native app builder that generates real React Native and Expo code from a plain-English prompt, a Figma file, or a screenshot, then runs it live so you can preview the app on your own device through Expo Go.
Unlike browser-only builders, GenVibe outputs an actual Expo project you can read, edit, and take with you: a component tree in React Native, file-based routing via expo-router, and a package.json you recognize. An AI agent plans the work, writes the code, and boots the app in a cloud sandbox. You iterate by chatting or by clicking elements in the live preview — and the same prompt can target web as well, so you are not locked into a single platform.
This page is for developers who already know they want React Native / Expo. Below, we cover the exact stack GenVibe outputs, how prompt-to-RN and Figma-to-RN work, on-device preview with Expo Go, where EAS fits for signed store builds, and how to wire up a Supabase backend.
The stack an AI React Native app builder should actually output
GenVibe scaffolds a standard, idiomatic Expo project — not a proprietary format you have to escape from later. That means the generated code uses the primitives and conventions you would reach for by hand, so you can review a diff, drop into a file, and keep going.
The point of an AI React Native app builder is to remove the boilerplate, not the transparency. Everything the agent writes is real code sitting in real files, so nothing about the output is a black box.
- React Native for the UI layer — View, Text, Pressable, FlatList and the component model you already know.
- Expo as the toolchain, so the project runs through the managed Expo workflow and the Expo Go client.
- expo-router for file-based navigation — screens map to files, layouts nest, and routing stays declarative.
- A conventional project layout (app directory, components, package.json) that reads like a project a human wrote.
- TypeScript-friendly components and styles you can refactor, extend, or wire into your own modules.
Prompt-to-RN and Figma-to-RN: three ways to start
You can begin from whatever artifact you already have. Describe the app in plain English and the agent plans the screens, generates the React Native components, and wires up expo-router navigation between them. Because it runs the app as it builds, you see a working screen rather than a wall of untested code.
Already have a design? Paste a Figma file URL and GenVibe imports it natively, translating the layout into React Native components and styles. Or upload a screenshot of a UI — screenshot-to-code turns the image into a starting React Native screen you can then refine by prompt.
In every case the flow is the same: generate, run, then edit. You refine by chatting with the agent or by clicking an element directly in the live preview to change it, which keeps the loop tight even for fine visual tweaks.
- Prompt to React Native: describe the app, get a running Expo project with navigation.
- Figma to React Native: paste a Figma file URL for native import into RN components.
- Screenshot to React Native: upload a UI image and get a starting screen as code.
- Edit by chat or by clicking elements in the live preview — no manual re-scaffolding.
Live preview and on-device testing with Expo Go
The agent runs your app in a cloud sandbox the moment it is scaffolded, so there is a live preview from the first build. For true device testing, GenVibe uses the standard Expo workflow: open the Expo Go app on your phone and scan the QR code to load the project on real hardware — real touch targets, real gestures, real device rendering.
This matters for React Native specifically, because a lot of what you need to verify — safe-area insets, keyboard behavior, list scrolling, native feel — is only trustworthy on an actual device. Because GenVibe works from any device, including a phone, you can prompt, preview, and adjust without a local dev machine or a full native toolchain installed.
From Expo project to a store build with EAS
Here is the honest boundary, stated plainly. GenVibe generates and runs the React Native / Expo project; it does not submit apps to the App Store or Google Play for you. Producing signed iOS and Android binaries is done off-platform through Expo's build service, EAS (Expo Application Services).
Because the output is a conventional Expo project, that hand-off is the normal one: take the generated code, run it through EAS Build to produce signed binaries, and submit to the stores as you would with any Expo app. There is no lock-in and no one-click store publish to over-promise — you own standard code that slots into the Expo release pipeline you already trust.
Connecting a Supabase backend
Most real apps need data and auth, so GenVibe lets you connect a Supabase database and authentication in one click. From there you can prompt the agent to read and write your tables and add sign-in, and it wires the client calls into the React Native app.
That gives you a full loop from a single prompt: a live-running Expo front end plus a real backend, without leaving the builder to stitch services together by hand. If you also want a web version, the same prompt-driven workflow builds web apps too — and web apps can be published to a live URL from inside GenVibe.
Example prompt to start with
Build a habit-tracking mobile app in React Native with Expo. Use expo-router for navigation with a bottom tab bar (Today, Habits, Profile). On Today, show today's habits as check-off cards with a streak counter; Habits lets me add, edit, and delete habits with a name, icon, and target frequency. Add a Supabase backend for auth and to store habits and daily check-ins per user. Keep it clean and mobile-native with safe-area padding.

Frequently asked questions
What is an AI React Native app builder?
An AI React Native app builder is a tool that turns a plain-English prompt (or a Figma file or screenshot) into real React Native code. GenVibe scaffolds a full Expo project with expo-router navigation, runs it live in a cloud sandbox, and lets you preview it on your own phone via Expo Go — all without writing the boilerplate by hand.
Does GenVibe generate real React Native and Expo code?
Yes. GenVibe outputs a standard, idiomatic Expo project using React Native components and file-based routing with expo-router. It is real code in real files that you can read, edit, and take through the normal Expo pipeline — not a proprietary or locked-in format.
How do I preview a React Native app built with GenVibe on my phone?
GenVibe runs your app in a cloud sandbox and gives you a live preview immediately. To test on real hardware, install the Expo Go app on your phone and scan the QR code to load the project on-device, where you can check touch, gestures, and native rendering.
Can GenVibe publish my React Native app to the App Store or Google Play?
No. GenVibe generates and runs the React Native / Expo project, but it does not submit apps to the stores. Signed iOS and Android builds are produced off-platform through Expo's EAS build service. Because the output is a conventional Expo project, that hand-off is the standard Expo release workflow with no lock-in.
Can I import a Figma design into React Native with GenVibe?
Yes. Paste a Figma file URL and GenVibe imports it natively, translating the layout into React Native components and styles. You can also upload a UI screenshot to generate a starting screen, then refine either one by chatting with the agent or clicking elements in the live preview.
Can I add a backend to my React Native app?
Yes. You can connect a Supabase database and authentication in one click, then prompt the agent to read and write your data and add sign-in. That gives you a live-running Expo front end plus a real backend from a single prompt-driven workflow.
How much does GenVibe cost?
GenVibe is free to start with no credit card required, so you can build a working app on free credits first. Paid plans start from $12/month — see the pricing page for details.
