nucleusUI
Open source, MIT licensed

The component library with a positive charge

nucleusUI is polished shadcn/ui components you copy straight into your repo. Own the code, skip the dependency.

Copy, own, ship

Every component ships with its full source. You paste the file into your repo, rename what you want, delete what you don't, and nothing lives in node_modules waiting to break your next upgrade. 

Each detail page shows the exact file path and a one-click copy of the full source. No CLI, no registry to configure.

Why copy from nucleus

Components

Ten components, one design system

Buttons, inputs, forms, switches, tabs, accordions, avatars. Every piece shares the same violet accent, the same radii, the same motion physics. Use one or use them all.

Ownership

Your repo, your rules

No lock-in, no version churn, no waiting for a maintainer to merge your edge case. The code is in your repository and follows your standards from day one.
