What is App0?
App0 is an AI-native full-stack app builder that uses GPT-5.6 or Claude 5 to automatically plan, code, run, test and fix complete web applications from written requirements. Users describe their idea, choose a model, and receive a working app with isolated HTTPS preview and exportable codebase they fully own.

Frequently asked questions about App0
How is App0 different from a regular code generator?
App0 plans, writes, runs and fixes the entire project in an isolated workspace, not just generate snippets.
Do I need to know how to code?

Who owns the generated code?
You own all code generated and exported through App0 and may modify, deploy or commercialize it.
Are my project and data secure?
Every task runs in an isolated sandbox with separate workspaces and transparent execution logs.
Can App0 work on an existing project?
Yes. Upload your project and App0 can add features, fix issues or improve the experience within its existing structure.
