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

Softr

Strengths

  • Turns a prompt into a full app: database, pages, user groups and navigation
  • Connects to 15+ data sources with two-way sync (Airtable, Google Sheets, Supabase and more)
  • Built-in auth, user groups and permissions, with SSO and SOC 2 Type II

Limitations

  • No access to the underlying code
  • Mobile is delivered as a PWA, not a native app
  • Focused on business apps and portals rather than consumer apps

Plans

Pricing

Softr

  • Free $0
