What it generates Native mobile apps for iOS and Android (plus web), from a prompt The backend rather than the whole app: database, REST APIs, custom functions, middleware, background tasks and triggers, with the frontend left to another tool
Stack and frameworks React Native PostgreSQL with Redis caching and Docker microservices; logic is built visually or written as XanoScript, which the CLI syncs to files on disk; works with React, Next.js, Flutter, Webflow, Framer and AI-generated frontends from Lovable and Bolt
Auth and database Managed backend with a choice of Convex or Supabase for the database, plus built-in push notifications PostgreSQL with unlimited records from the Essential tier; authentication endpoints (/signup, /login, /me) ship by default on JWE tokens, with role-based access control and enterprise SSO through GitHub, Google and Microsoft

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

Xano

Strengths

  • Self-hosting on Azure, AWS, GCP or on-premise, not only the vendor's cloud
  • Frontend-agnostic: pairs with React, Flutter, Webflow, Framer, Lovable or Bolt rather than dictating one
  • An official MCP server, so external AI agents build against the same workspace rules

Limitations

  • The first paid tier is $85 a month, a steep step up from the free one
  • It builds only the backend, so a second tool is needed for the interface
  • The free tier is rate-limited to 10 requests per 20 seconds and watermarks stored images

Plans

Pricing

Xano

  • Free $0 Core building tools, rate-limited to 10 requests per 20 seconds. Up to 100K database records, 1GB watermarked image storage, 1 workspace.
