Dancer2 is the new generation lightweight web-framework for Perl. It's a complete rewrite of Dancer based on Moo.
Yes, you can use Dancer2 in production. It works.
You can get more information about the Dancer project on the website: http://perldancer.org.
An application can be as simple as this simple hello world script:
use Dancer2;
get '/'=>sub { "Hello World" };
dance;
