21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!
