At Cloudflare we have been building a new component library on top of @base_ui – we call it Kumo. It's an opinionated style layer on top of accessible components with some additional tools, such as: - Pre-styled components - Figma plugin (code -> design) - Streaming UI support - AI-ready component registry - CLI Why are we sharing this? We love to give back to the internet. We don't expect this to be a library that everyone adopts and uses in all of their projects. Maybe you like it and want to use it & that's great. But we can share our tooling and our learnings with the community to make developing beautiful UI's easier. If you have been looking at the Cloudflare dashboard UI for the past few months you have probably noticed this new component library in action. While we have a long way to go to make it perfect.... we're happy with how it's coming along! Huge shoutout to all the contributors who have helped build this internally. Wouldn't be where it is without all the help :) @JonnieLappen @mattrothenberg @superhighfives @nandafyi @hkfoster @invisal89 @RozenMD @bradgarropy + Rob & many more
