About App0

App0 is an AI-native app builder that converts a written description into a complete full-stack application using GPT-5.6 or Claude 5. It constructs frontend, backend, database, and API components inside an isolated development environment. The system runs type checks and automated tests before delivering a live HTTPS preview and a full exportable codebase that the user owns. Iterative refinement is supported through natural language chat, allowing users to adjust the app without writing code. The tool abstracts infrastructure setup, enabling rapid prototyping and deployment of production-ready applications. It is designed for founders, product managers, and developers who need to quickly validate ideas or build functional prototypes. App0 removes the need for manual coding or complex DevOps, focusing instead on translating user intent into working software.
