Free React Components for Tailwind CSS
Watermelon UI is a free, open source library of React components for Tailwind CSS. It has more than 500 component variants across 30 categories, from buttons and dialogs to data tables and date pickers. You can install each one with the shadcn CLI or copy and paste the code, and everything is MIT licensed.
Because the code is copied into your project, you own it. You can edit the markup, restyle it, or delete what you do not need without waiting on a library release.

Why copy-paste instead of an npm package
A copy-paste library gives you the source instead of a dependency. You get full control over styling and behavior, and there is no version upgrade that breaks your UI. The tradeoff is that you maintain the code yourself. Read copy-paste vs installed component libraries for the full comparison.
Frequently asked questions
Is Watermelon UI free?
Yes. All components, blocks, dashboards, and templates are free and MIT licensed. There is no pro tier.
Does it work with shadcn/ui?
Yes. Components are published as a shadcn registry, so npx shadcn@latest add installs them into an existing shadcn project.
Do I need Tailwind CSS?
Yes. Components are styled with Tailwind CSS utility classes and CSS variables.
