Base UI has gone from 0 → 17M weekly downloads in ~21 months. Last week we overtook radix-ui. It's now the #1 UI library.

Came across this gallery I was exploring a while back. @base_ui scroll container and css scroll snap with velocity based image rotation using @motiondotdev scroll momentum. Each image has a subtly random mass so that they don't rotate or rest uniformly to feel more natural.

Do you want a versioned, npm-distributed CSS file that, when imported, makes Base UI components look gorgeous? Same components, same API, nothing changes. Just each part has a corresponding CSS class. Then use Tailwind for layout/text/overrides. Sample design in thread.

Base UI's Line Chart handling streaming 120 points per second on a 10k point data window with zoom and pan enabled, keeping steady ~120fps. In case for some reason you need something like that 😅🚀

Starting today, we are making @base_ui the default component library in shadcn/ui. First, a bit of history. When shadcn/ui launched in 2023, it was built on Radix. At the time, nothing else came close. Headless. Accessible. Composable. Fast forward a few years and the team who built Radix are building something new: Base UI.
