Escher vs Rapidoid: What are the differences?
Escher: 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; Rapidoid: No-Bullshit Web Framework for Java. Rapidoid consists of several de-coupled modules/frameworks which can be used separately or together: http-fast, gui, web, fluent, u, and more.
Escher and Rapidoid can be primarily classified as "Frameworks (Full Stack)" tools.
Escher and Rapidoid are both open source tools. It seems that Rapidoid with 1.42K GitHub stars and 134 forks on GitHub has more adoption than Escher with 312 GitHub stars and 63 GitHub forks.
