After a small research, I found Template::Alloy and loved it. It also allows you to set a default filter.

There is Dancer adapter for it Dancer2::Template::Alloy, but it has a typo in README. I create a PR and hoping it will be merged.

Here is the valid config (config.yml part):

# template engine
template: "alloy"
engines:
  template:
      alloy:
        AUTO_FILTER: html
