Two years of UI experiments. 159+ components built on coss-ui, all on the shadcn registry. Press 'c' on any design to copy the source.
devl.dev is Sean's scratch pad of 158 UI experiments made over two years, built on the coss-ui library of Tailwind CSS v4 and Base UI components and published on the shadcn registry. The designs are grouped like a product's screens, from app shells and auth flows to dashboards, tables, filters, empty states, coachmarks and comment threads, with raw CSS, shaders and SVG mixed in. Turn to it when a screen like a workspace rail or a two-factor prompt needs a coded reference, since pressing c copies any design's source.
