Full Comparison

Criterion a0.dev Adalo
Starting price Not stated Free plan; paid from $36 / month Annual billing is the rate shown by default; monthly billing costs 20 percent more. Plans differ mainly in published apps (1 on Starter, 2 on Professional, 5 on Team), editors and storage. Publishing to the stores also needs an Apple Developer account ($99 / year) and a Google Play developer account ($25 one-time), both charged by Apple and Google directly.
Free trial Not stated Free plan with unlimited test apps, 500 records per app and no publishing
Output Native iOS and Android apps (React Native), plus web Native iOS and Android apps plus a responsive web app from one project
API Yes Yes, a Collections API and a Notifications API, plus custom actions against any REST API
What it generates Native mobile apps for iOS and Android (plus web), from a prompt Native iOS and Android apps plus a responsive web app from one project, assembled on a multi-screen canvas or built and edited by prompting the Ada assistant
Stack and frameworks React Native Visual no-code editor with more than 200 drag-and-drop components; a developer mode allows private custom components, and a marketplace adds third-party ones
Auth and database Managed backend with a choice of Convex or Supabase for the database, plus built-in push notifications Built-in hosted Postgres database with relational collections; outside data through external collections over REST, Google Sheets and Xano, which can also supply external users
Hosting and deploy One-click publishing to the App Store and Google Play (IPA/APK), with a web preview Published to an Adalo-hosted domain or a custom domain, and from paid plans to the Apple App Store and Google Play
Payments Built-in monetization: subscriptions and one-time purchases via the App Store Yes, Stripe payments collected inside the app
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 Custom components rather than an exportable codebase. A component is bootstrapped outside Adalo with the create-adalo-component tool, which needs Node 10.2 or newer and developer mode enabled on the account, and is published with npx adalo publish, either publicly or privately. Code otherwise reaches an app from the outside: custom actions call any external REST API, and the Adalo API, documented for the Team and Business plans at up to 5 requests per second, reads and writes the app's collections and triggers push notifications. The developer documentation covers building and publishing components and does not document exporting an app's own source

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

Adalo

Strengths

  • One project publishes as a native iOS app, a native Android app and a web app
  • Ada, the AI assistant, is included on every plan with no token or usage charges
  • Built-in relational Postgres database, so no external backend is required to start
  • Flat monthly price with no usage-based or per-action charges

Limitations

  • The free plan can build and test but cannot publish an app
  • Published apps are capped per plan, so shipping several apps means moving up tiers
  • App store publishing needs paid Apple and Google developer accounts on top
  • Email support runs on a response-time SLA of three, two or one business days depending on the plan
