cf-ui vs Flight: What are the differences?

cf-ui: A set of over 50 packages used to build UIs at CloudFlare using projects such as React, Redux, npm, Lerna, and more. While moving to React, we’ve taken our existing Backbone UI framework and rebuilt it from scratch on top of React. This includes over 50 packages that include dozens of components, utilities, test helpers, and more; Flight: A component-based, event-driven JavaScript framework from Twitter. Flight is distinct from existing frameworks in that it doesn't prescribe or provide any particular approach to rendering or providing data to a web application. It's agnostic to how requests are routed, which templating language you use or even if you render your HTML on the client or the server. While some web frameworks encourage developers to arrange their code around a prescribed model layer, Flight is organized around the existing DOM model with functionality mapped directly to DOM nodes.

cf-ui and Flight can be primarily classified as "Javascript UI Libraries" tools.

cf-ui and Flight are both open source tools. Flight with 6.64K GitHub stars and 588 forks on GitHub appears to be more popular than cf-ui with 1.29K GitHub stars and 89 GitHub forks.
