Ballmac UI blocksfor shadcn/ui.

Ballmac UI is a React and Tailwind CSS v4 library built around making web apps feel native, with desktop-style surfaces such as app windows, docks, menu bars, command search and a live notch. Its free blocks and components also cover marketing pages, accounts, application screens, ecommerce, AI chat interfaces, backgrounds, text effects, motion and device frames, and blocks that show data come with loading, empty and error states. Items install through the shadcn CLI into components/ballmac.

Its own CLI adds two things: ballmac update merges new versions into files you've edited, and ballmac check runs your app through the same browser checks Ballmac publishes for its own items. The free library and its themes are MIT licensed. Pro, a one-time purchase, adds deeper app screens, Figma tokens and three starter apps. It's made by Ballmac, the team behind Binzide.
