a0.dev

a0.dev is an AI mobile app builder that creates iOS and Android apps from chat and handles publishing and monetization for founders and creators who want to launch a paying app. Where many app builders stop at a prototype, a0 bundles the parts that come after: a backend, in-app payments and subscriptions, analytics and a publishing flow that prepares the App Store Connect listing for you. It is backed by Y Combinator.

What is a0.dev used for?

People use a0.dev to go from an app idea to a live, revenue-generating app in the stores with as little setup as possible.

• Building and editing mobile apps by chatting with an AI coding agent
• Adding a database and backend with Convex or Supabase
• Using built-in APIs for AI inference and image generation inside the app
• Setting up payments and subscriptions to monetize the app
• Publishing with one click to the App Store, plus Google Play and the web
• Tracking users, subscriptions and performance in an analytics dashboard

Who a0.dev is best for

a0.dev fits solo founders and indie makers who want to test paid mobile apps, creators with an audience who want their own app, and small teams that prefer one platform for build, backend and billing. Developers who want to keep full ownership of the code can export it on the Pro plan. Companies with strict architecture requirements or existing native codebases will likely find a traditional development workflow more suitable.

a0.dev pricing

As of October 2026, a0.dev's pricing page lists two plans. Pro costs $20 per month for 100 credits and includes expanded messaging limits, access to advanced coding models, unlimited app builds, a custom domain without a0 branding, code export and a community role. Max costs $200 per month for 1,250 credits and adds access to its top AI models, 250 bonus credits each month and unlimited support calls. The pricing page does not show a free plan. Publishing to the App Store and Google Play also requires developer accounts that Apple and Google charge for separately.

Limitations to keep in mind

• No free plan is listed, so you pay to try it seriously
• Credit limits can constrain heavy iteration on the Pro plan
• Complex native features may still need a developer
• Store review rules still apply, so one-click publishing does not guarantee approval

a0.dev vs alternatives

Anything builds both web and mobile apps from prompts and is a direct competitor worth trying side by side. Bolt.new and Lovable are better suited to web apps and SaaS products than to native mobile. Replit is the stronger pick when you want a general cloud IDE and expect to write code yourself later. a0.dev stands out for bundling payments, analytics and App Store publishing into one mobile-first workflow.

Tips for getting started with a0.dev

Plan the core screens and the one action users will pay for before you start, so credits go toward the features that matter. Pick Convex or Supabase at the beginning rather than switching later. Test each build on your own phone with the a0 mobile app. Set up your Apple and Google developer accounts early, since verification can take several days.
