a0.dev is an AI app builder that turns natural-language prompts into native mobile apps and ships them directly to the App Store and Google Play.
The core of a0.dev is an AI coding agent that writes and edits your app in real time while you describe what you want. Instead of dragging components around a no-code canvas, you chat with the agent — asking for screens, features, or changes such as adding dark mode — and it searches the codebase, plans the change, and implements it. Apps are backed by real databases through Convex or Supabase, so they can store user data, accounts, and content like a conventionally built product. Built-in APIs for AI inference and image generation let the apps you create include smart features of their own, from generated imagery to AI-powered content, without separate integration work. The result is a shorter path from an idea to a live, store-listed application.
The experience is aimed at people who think in product terms: you describe screens, data, and behavior in ordinary language, and the agent handles the project structure, code, and configuration underneath, revising its work as your requirements change across the conversation.
a0.dev follows a freemium model: you can start building an app for free, and paid plans unlock higher usage limits and full publishing capabilities for shipping to the app stores.
a0.dev is designed for indie makers, startup founders, and non-technical creators who want a genuine native app in the stores without hiring a development team or learning to code. It is also a practical route for validating an app idea before committing to a full custom build.
