App0 is a desktop application built with Electron that allows users to generate and run small personal apps ("applets") using AI without coding, terminals, or installing dependencies. The application handles everything internally - app generation, installation, hosting, database setup, and launching.
App0 follows a modular architecture with these core components:
App0/ ├── core/ # AI logic, app generator, build runner │ ├── ai/ # Prompt templates and GPT communication │ ├── builder/ # File writer, bun installer, port allocator │ ├── runner/ # Manages background app processes │ └── registry.json # Metadata of all apps ├── apps/ # All generated user apps │ └── [app-name]/ ├── runtime/ # Local bun binary, shared modules (optional) ├── gui/ # App0 frontend (React) │ ├── AppList.tsx │ ├── AppWindow.tsx │ ├── CreateAppFlow.tsx │ └── index.tsx ├── main.ts # Electron entrypoint ├── package.json └── README.md

Since this is a new project, these commands will need to be established during development:
Electron Development:
npm run devbun run devnpm run buildbun run buildnpm run packagebun run packageGenerated Applets:
bun devbun startEach generated applet follows this structure:
