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

Rork

Strengths

  • Generates genuinely native code, Swift and SwiftUI on iPhone and Kotlin and Compose on Android, rather than a wrapped web view
  • Paid users own all generated code, with two-way GitHub sync back into the project
  • Rork Cloud gives an app a managed Postgres backend with no setup, and can be moved into your own Supabase organisation later

Limitations

  • Native iOS is only on the Max plan, from $200 per month
  • The free plan builds web apps only, and projects on it are public
  • Google Play publishing is a manual App Bundle upload
  • Expo and React Native projects can no longer be created, so a shared codebase for both phones is no longer an option

Plans

Pricing

Rork

  • Free $0 5 credits per day, up to 35 per month in major markets. Web apps only, projects are public.
  • Rork Pro From $20 Per month for 100 credits, up to $100 for 500. Native Android and web apps, private projects, dev mode.
