Flight vs T3: What are the differences?

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; T3: Client-side JavaScript framework for building large-scale web applications, created by Box. T3 is different than most JavaScript frameworks. It's meant to be a small piece of an overall architecture that allows you to build scalable client-side code. T3 is explicitly not an MVC framework. It's a framework that allows the creation of loosely-coupled components while letting you decide what other pieces you need for your web application. You can use T3 with other frameworks like Backbone or React, or you can use T3 by itself.

Flight and T3 can be categorized as "Javascript UI Libraries" tools.

Flight and T3 are both open source tools. It seems that Flight with 6.64K GitHub stars and 588 forks on GitHub has more adoption than T3 with 1.59K GitHub stars and 160 GitHub forks.
