Camping is not just Rails-without-all-the-extra-features. It's a worthy framework in it's own right, best suited for applications where Rails doesn't quite cut it. Unlike Rails, Camping is not specifically tied to CRUD-centered applications. This makes it the perfect platform for all those HTTP-based apps, where Rails doesn't quite make sense. This is why we chose it over Rails for the rubycas-server project and we couldn't be happier with the outcome.
