Before you launch
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 responsibilitiesMoving from Free to Pro
Stay 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.
A deliberate move from Free to Pro.
Start with the Pro foundation, carry over your product work and validate each integration before launch.
Set up the Pro foundation
Run the Pro source locally. Configure PostgreSQL, auth providers, email and Stripe in your development environment.
Follow the setup guideBring across your product work
Port your components, layouts and branding. Adapt routes, domain models and permissions to the Pro architecture.
Plan the move from FreeValidate before you launch
Test sign-in, account recovery, checkout, webhooks and access checks. Plan data migration and deployment for your own app.
Review the production checklist
Your product work comes with you.
Free and Pro share the PyColors UI foundation. Reuse the parts you have shaped, then adapt them to real sessions and data.
- Components and page layouts
- Branding, content and theme tokens
- Product workflows you have validated
This is a source-code upgrade. Buying Pro does not automatically migrate your app, move your data or deploy it.
