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

Base44

Strengths

  • Zero configuration, database, auth and hosting are handled
  • Fastest path for non-technical founders
  • Generates real code, with two-way GitHub sync and a CLI eject
  • Stripe payments wired up from the chat

Limitations

  • Less control and flexibility than code-first tools
  • GitHub sync is permanent, a project cannot be transferred back to Base44
  • An ejected project carries the entity schemas but starts with an empty database
  • Now part of the Wix ecosystem
  • Newer platform
