| Data persistence | Projects persist in this browser's localStorage when available; no shared database or cross-device synchronization. | Prisma + PostgreSQL foundations for auth and billing; wire your own domain data. |
| Mobile experience | Responsive web UI. | Responsive UI plus installable PWA foundations; auth and billing stay online-first. |

Starter Pro is source code, not a hosted service. You still configure PostgreSQL, auth, email, and Stripe, validate the integrations, and complete the production checklist. Buying Pro does not provision or deploy your app.
Review production responsibilitiesStay on Free while validating screens and workflows. Choose Pro when real accounts and payments become the next implementation step. Pro is separate source code to configure. Bring your existing UI work across deliberately; buying Pro does not automatically migrate your app or data. It does not unlock the running Free demo.
Inspect the setup, plan the transition and make the interface your own.
