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.
