Access to the code Projects are built on Expo and edited by the agent inside a0's own workspace. The documentation covers runtime and Expo SDK upgrades, over-the-air updates and store publishing, and documents no source-code download, GitHub sync or local development Compiled builds rather than a repository: downloading an Android app sends an APK by email, and publishing sends an AAB to upload to the Play Store. No source-code export or Git sync is documented, so edits stay in the builder

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

Thunkable

Strengths

  • AI Builder turns a written description into a working, fully editable project
  • One project publishes to iOS, Android and the web
  • Visual blocks and a built-in code editor sit side by side, so edits are not limited to prompting
  • Documented data sources and integrations cover Firebase, Google Sheets, Airtable, OpenAI, RevenueCat and more

Limitations

  • The free plan has no private projects and no published apps
  • Every plan meters AI use by token allowance
  • Live published apps are capped below the Advanced plan
  • Private projects fall back to read-only if the subscription lapses
