Flux vs T3: What are the differences?

What is Flux? Application Architecture for Building User Interfaces. Flux is the application architecture that Facebook uses for building client-side web applications. It complements React's composable view components by utilizing a unidirectional data flow. It's more of a pattern rather than a formal framework, and you can start using Flux immediately without a lot of new code.

What is 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.

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

Flux and T3 are both open source tools. It seems that Flux with 16.2K GitHub stars and 3.62K forks on GitHub has more adoption than T3 with 1.59K GitHub stars and 160 GitHub forks.
