Less was created in 2009 by Alexis Sellier, more commonly known as @cloudhead. Originally written in Ruby, it was then ported to JavaScript.

In May 2012 Alexis relinquished control and development over to a core team of contributors who now manage, fix and extend the language.

Less is maintained by a group of invaluable core contributors, with the massive support and involvement of our community. No one person is in charge and everyone has their own areas and donates the time they can afford. In alphabetical order:
