Flight vs Riot: What are the differences?

Developers describe Flight as "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. On the other hand, Riot is detailed as "A React-like user interface micro-library". Riot brings custom tags to all browsers. Think React + Polymer but with enjoyable syntax and a small learning curve.

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

Flight and Riot are both open source tools. It seems that Riot with 13.7K GitHub stars and 1.02K forks on GitHub has more adoption than Flight with 6.64K GitHub stars and 588 GitHub forks.

BestFone 2.0, Walla!, and Thanx are some of the popular companies that use Riot, whereas Flight is used by Adtena, Birchbox, and Drip. Riot has a broader approval, being mentioned in 9 company stacks & 6 developers stacks; compared to Flight, which is listed in 4 company stacks and 3 developer stacks.
