  • Built-in monetization with subscriptions and one-time purchases
  • Convex backend and push notifications wired in

Limitations

  • Output is React Native on Expo, so you work within that stack rather than a framework of your choice

Lovable

Strengths

  • Full-stack generation with auth, database and payments
  • GitHub sync keeps code portable
  • Polished professional components

Limitations

  • Lovable Cloud convenience can lead to vendor lock-in
  • Credit costs rise with larger builds
