Codecube.io is a jsfiddle type service which runs Perl code (and other languages) and shows the results in your browser.

The website is written in Go and runs your code inside a Docker container. It originally had support for C, Go, Python, and Ruby. I was looking for an excuse to play with Docker and Go so I submitted a pull request which added support for Perl.
