Compare to Unfiltered, which seems to be a little lower level.

As a scala beginner, but a proficient sinatra user, I'm trying to decide which would be a good choice for my next project. Thoughts?

I am a little anxious about having to deal with the ultra-heavyweight java server architectures, especially coming from the world of rack/thin/passenger/etc. but I guess I'll cope. Either that or just use GAE.

I looked a Scalatra recently. I found it a little slow but don't take my word for it.

I would suggest hitting whatever you're looking at with apache bench to see how it copes with 'hello world'. I ended up using Jetty and servlets written in Scala.

After all the drama on here recently surrounding inappropriate webapp benchmarking, I don't think that's great advice.

I missed the drama so I probably don't have anything insightful to add. However, I find that when trying out frameworks its nice to know what kind of overhead they have for the convenience they provide.

We're using it, and jade to genereate views

We're using Scalatra for our company's http service, and it's been great. Simple, good documentation, works exactly as promised, and the irc room (thanks Ross Baker!) has been extremely helpful.

If you use Scalatra for a major project, though, be ready to learn at least a bit about Jetty (or Tomcat or...). Scalatra is a great tool for writing Java servlets, but you're ultimately running those servlets in a much more complicated servlet container.

That's unfortunate. The last time I made a pet web application in Scala it was using the Lift framework. The greatest pain points by far came from integrating with all the Java infrastructure, including Jetty. I hope someday someone figures out a good abstraction layer for some of these Java services to simplify their use, but as I'm unfamiliar with the needs of those who are actually deploying web servers, I don't even know if this is possible or feasible.

I wrote and deployed a Scalatra project last month and found the framework to very intuitive, powerful, and flexible.

Not to mention that the team working on the project is amazingly helpful; especially when you are new to scala :)

we ported an analaytics project from a scripting language processing the incoming data to scalatra running with akka on the jvm. we went from 250 requests per sec to 5200 (per server), by using scalatra with akka actors to handle the data in an async manner. #win

Looks really good, from the docs. Amazing what other projects Sinatra has spawned by setting a good example. One of my customers and I have been hacking with Clojure and Noir - Noir also reminds me of working with Sinatra: same light-weight feeling.

I really like this framework it brings a nice clean implementation of the sinatrarb to scala. Creating REST services or web apps is a breeze.
