Bolt builds web apps in the browser, with hosting and databases on its Free plan, Bolt Database or Supabase on Pro, and an Expo workflow for phone apps. VULK builds websites, full-stack web apps, Flutter phone apps and 3D scenes from a description, and each project can have its own database, email and password sign-in and REST API. Already on Bolt? Download the project as a ZIP and import it into VULK: app.vulk.dev/import/bolt. The import brings the code; move the data and secrets on their own.

Use the same project brief before choosing
Ask each platform to build the same application: a booking service with two user roles, persistent appointments, a working cancellation flow and responsive screens. Check the complete journey, then request one meaningful change. If your product needs mobile or 3D, include that requirement in the original brief and check the delivered app on the intended device.
