Escher vs Volt: What are the differences?
Developers describe Escher as "An Elm-like web framework for Julia". A web server for 2016. Escher's built-in web server allows you to create interactive UIs with very little code. It takes care of messaging between Julia and the browser under-the-hood. It can also hot-load code: you can see your UI evolve as you save your changes to it. On the other hand, Volt is detailed as "A ruby web framework where your ruby runs on both server and client". Volt is a ruby web framework where your ruby code runs on both the server and the client (via opal.) The DOM automatically update as the user interacts with the page. Page state can be stored in the URL, if the user hits a URL directly, the HTML will first be rendered on the server for faster load times and easier indexing by search engines.
Escher and Volt can be primarily classified as "Frameworks (Full Stack)" tools.
Escher and Volt are both open source tools. It seems that Volt with 3.3K GitHub stars and 209 forks on GitHub has more adoption than Escher with 312 GitHub stars and 63 GitHub forks.
