The trade-offs

Strengths and Limitations

Bubble

Strengths

  • Builds web and native mobile apps in a single editor
  • Generates a complete app from one prompt with the AI app builder, then lets you refine it
  • Large ecosystem of community-made plugins and connectors

Limitations

  • Priced in monthly workload units, so a busy app's running cost rises with usage instead of staying fixed
  • The free plan cannot run a live app on a custom domain

FlutterFlow

Strengths

  • Exports the full Flutter and Dart source code, so there is no vendor lock-in
  • Builds native iOS, Android and web apps from a single project
  • Built-in Firebase and Supabase integrations for data and authentication

Limitations

  • AI Gen requests are capped per plan (5 lifetime on the free plan, up to 500 per month on Business)
  • Real-time collaboration and GitHub sync require the Growth plan or higher
