What is Vibra Code?

Vibra Code is an open-source AI app builder that lets you create mobile apps by describing them in plain English. The backend runs Claude Code (Anthropic's AI coding CLI) inside an E2B cloud sandbox to generate complete apps while you watch in real time. Then you see a live preview — right on your phone.

Think of it as an open-source alternative to Vibe Code App, Rork, Lovable, and Bolt.new — but you can self-host it, customize the AI prompts, swap AI providers, and fork it to make it your own.

This is the complete source code behind the app on the App Store. Built by one developer with Claude Code. Now open source.

Why Open Source?

Every other AI app builder is closed-source. You can't see how it works, can't customize it, can't self-host it.

Looking for an open-source vibe coding app? This is it. Fork it, self-host it, make it yours.
