Ask HN: framework for webapps in Scala

Depends on how deep you want to go.

Lift is very "Scala-ey" and has some great features for building full applications - FourSquare is lift powered, by way of example. www.liftweb.net

Play has Scala integration, but I don't know much about it to comment either way.

If you want to get more 'lightweight' or bare bones, Scalatra is a port of Ruby's Sinatra framework. Its what I tend to think of as a microframework, it's quite cool: https://github.com/scalatra/scalatra

Annotation based configuration of controllers, etc

Lift is probably the most mature as well as the most documented Web Framework there is for Scala.

Try the Play Framework
