a0.dev — Build mobile apps from a chat prompt — Expo / React Native code shipped to a phone in minutes. Generates Expo / React Native mobile app code directly from natural language chat prompts.
About a0.dev
a0.dev is an AI app builder that generates Expo / React Native mobile app code from a chat prompt. It runs in a web browser, so you don't need a local mobile dev toolchain to get started.
Its angle is the short path from prompt to phone: it produces runnable code you can install on a device in minutes, all from natural-language chat.
It fits beginners and anyone prototyping mobile apps fast. It's a poor fit if you need native desktop or pure web output, since it only targets Expo / React Native, or if you want an IDE or CLI client — access is web-only, with no VS Code, JetBrains, or command-line option. The free tier also caps usage relative to paid plans.
Among AI app builders, a0.dev is narrower than general-purpose ones: it commits to the Expo / React Native mobile stack rather than covering web and desktop targets.
