FAQ

Is this a subscription?

No. Every product and the bundle are one-time payments. You download the source and keep that version. Later Designyff updates are not included automatically.

What do I receive?

A zip of the project: README, .env.example, and the application or component source. Dependencies install locally. Paid files are not on the public site. Download starts after Stripe confirms payment.

Can I use this for client work?

Yes. Use and modify the code in personal, commercial, and client projects. Do not resell the original source as a competing kit. Attribution is optional.

Where are the free UI components?

The copy-and-paste component library is still at /all/. The store is starter kits and the bundle.

Start from a working foundation.
