Vibra Code — open-source AI mobile app builder

★ 133

Vibra Code is an open-source AI builder for mobile apps: you describe an app in plain text, by voice or with a mockup screenshot, an agent writes the code in a cloud sandbox, and a live preview appears on your phone. Reach for it when you want to prototype a mobile app without hand coding, need a self-hosted alternative to Lovable or Bolt.new for mobile, want to change prompts and AI providers, or plan to fork it for your own product. Inside are an iOS app on a modified Expo Go, a Next.js 15 and Convex backend, Inngest job queues, isolated E2B sandboxes, Claude Code as the default agent (Cursor and Gemini via one environment variable), GitHub integration and optional Stripe and RevenueCat. You need keys for Anthropic, E2B and Clerk plus a Convex deployment, and the mobile app builds only on macOS with Xcode. The direction is mobile apps from a description, not websites. It differs from Vibe Code App, Rork, Lovable and Bolt.new by being open source and self-hostable. Suited to developers and startups; it is not a no-setup no-code tool. AGPL-3.0 license.
