Hey Product Hunt! I'm Musabbir Sagar, the maker.
Built BracketUI because I kept running into the same problem — most component libraries either lock you in with heavy styling or give you nothing at all. BracketUI sits in the middle. Pre-built, minimal, and fully customisable through component-level theme props.
The MegaMenu and three-way ThemeToggle (light, dark, system) were the two things I couldn't find anywhere else that actually worked properly in Next.js App Router.
