a0.dev

a0.dev is an AI-core mobile-app development platform that lets you build without a traditional development environment — describe needs in conversation, and an AI coding agent writes and edits code in real time, turning ideas into publishable mobile apps. The official tagline plainly says "Build mobile apps. Make money." — its positioning is to help indie developers and creators quickly build and monetize apps. It supports one-click publishing to the App Store and Google Play, has built-in monetization tools like payments and subscriptions, the database can connect Convex or Supabase, and it integrates AI-inference and image-generation APIs and provides an analytics dashboard to track users and performance; there's even a native mobile app to remotely edit and deploy from your phone. The company discloses over 200,000 users, over 300,000 apps produced, and backing from Y Combinator.

Features and use scenarios: a0.dev suits indie developers wanting to quickly validate ideas, freelancers, and creators without an engineering background wanting to launch small tool-type or content-type apps. Compared to hand-coding React Native from scratch, it links building, database, payments, and publishing end-to-end, greatly compressing the time from idea to launch. Note that complex or highly customized business apps may still need engineer involvement to tune, and AI-generated code is advised to be tested and reviewed before going live.
