The trade-offs
Strengths and Limitations
a0.dev
Strengths
- Generates a full React Native app and publishes it to the App Store and Google Play
- Built-in monetization with subscriptions and one-time purchases
- Convex backend and push notifications wired in
Limitations
- Primarily a mobile app builder: it generates native iOS and Android apps, with web as a secondary target
- Output is React Native on Expo, so you work within that stack rather than a framework of your choice
v0
Strengths
- High-quality React and Next.js UI code
- Integrates into an existing codebase with no new platform
- Great for Next.js teams
Limitations
- Leans toward the frontend, with no managed auth or payments built in
- Best value inside the Vercel ecosystem
