Escher vs Scalatra: 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, Scalatra is detailed as "* An open source web application framework written in Scala*". It combines the power of the JVM with the beauty and brevity of Scala, helping you quickly build high-performance web sites and APIs.
Escher and Scalatra can be primarily classified as "Frameworks (Full Stack)" tools.
Escher is an open source tool with 313 GitHub stars and 64 GitHub forks. Here's a link to Escher's open source repository on GitHub.
