Bundled Libraries (Offline, No Downloads)

NearbiJSX bundles the most popular libraries used in AI-generated artifacts — all offline, no CDN needed:

- React 18 & Tailwind CSS 3
- Sucrase (fast JSX transpiler) & Babel
- shadcn/ui components (Button, Card, Alert, Badge, Input, Dialog, and more)
- Lucide React icons
- Recharts (charts & graphs)
- Lodash

Your AI artifacts will look and work exactly as intended.

How It Works

1. Paste JSX from your AI assistant — or generate it directly in-app
2. NearbiJSX transpiles (via Sucrase) and renders it instantly
3. Organize with folders, tags, and favorites
4. Export or share with nearby devices

AI Code Generation

Bring your own API key for ChatGPT, Gemini, or Anthropic. GitHub Models is also available with free daily limits — no API key purchase needed. Keys are stored locally in your device's Keychain and are never sent to our servers.

Secure by Design

All JSX runs in a sandboxed environment. Network calls, storage access, and dangerous APIs are blocked before your code executes. No data leaves your device unless you choose to export or share.
