v0 by Vercel is an AI-powered tool that generates web UI components from text descriptions and images. It produces React components styled with Tailwind CSS and shadcn/ui. The tool excels at creating polished web interfaces quickly, and the output integrates cleanly into Next.js applications.
The limitation of v0 is scope. It generates individual UI components for the web, not complete native mobile applications. It does not produce React Native code, does not handle navigation or state management, and does not include backend integration. You get a component, not an app.
Fastshot generates complete native mobile applications from natural language descriptions. This includes screens, navigation stacks, tab bars, authentication flows, database integration, push notifications, and deployment configuration. Where v0 gives you a piece, Fastshot gives you the whole picture, specifically optimized for mobile.
For native mobile apps, try our [AI mobile app builder](/ai-app-builder) instead.

A mobile app needs navigation, state management, data fetching, error handling, and platform-specific configurations. Fastshot generates all of this, not just visual components.
React Native components are fundamentally different from web components. Fastshot generates proper ScrollView, FlatList, TouchableOpacity, and platform-aware components that feel native on each OS.
Fastshot includes Supabase authentication with login, signup, password reset, and session management built into the generated app. v0 does not handle any backend logic.
Every Fastshot app gets a PostgreSQL database and file storage through Supabase. Your app can persist data, upload images, and query records without any additional setup.
Fastshot compiles your app into store-ready binaries. Going from code to App Store submission is a built-in workflow, not an afterthought.
Fastshot lets you iterate on the entire app through conversation. Add screens, change flows, adjust logic, and refine features continuously. v0 handles one component at a time.
