We’re proud to program it in Perl based on TDD. Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. More about why we love Perl….
We use Mojolicious, a real-time web framework. We use MySQL. It’s the world’s most popular open source database. With its proven performance, reliability, and ease-of-use.
We use a lot of powerful free source like GNU/Linux Ubuntu, KVM or Spice, among others. Responsive web made with Bootstrap and AngularJS.
We use Weblate to provide a cleaner and easy to use interface for translators. It’s meant for adapting applications and text to enable their usability in a particular cultural or linguistic market.
Then we build documentation and host it in Read the Docs for you.
