Build mobile apps from a chat prompt — Expo / React Native code shipped to a phone in minutes.
a0.dev is a 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.

- What Is an AI Agent Harness? The Runtime That Turns an LLM Into an Agent
A harness is the runtime wrapper that turns a bare language model into an agent — the layer that runs tools, holds memory, assembles context, and enforces limits. The model does the reasoning; the harness does everything the model can't do on its own. It's the part that decides whether you shipped a chatbot or a real agent — and it's why the same model feels brilliant in one tool and useless in another.

Claude Code has built-in memory — a CLAUDE.md file it reads each session — but it only holds short, hand-written notes. To make it understand a large codebase or docs set, you add a second brain: turn the repo into a knowledge graph, fold that into an Obsidian vault, and let the agent query the map instead of re-reading every file.

Here's the honest, hands-on version for a maker whose site shipped last week.
