The Cosmos website committee was founded on June 15, 2016 by Manuel Muñoz Sánchez and Niels de Jong, who built the first website. On July 14th of the same year, the first Cosmos website was launched. Although functional, many features of the website's framework were hard to scale and difficult to maintain. Later, in 2017, the idea for a new website arose and was implemented during the last months of 2017.
With help from senior developer Bram Mulders and designer Alan Wever, the current version of the website was launched on the 21st of December 2017. This website and accompanying back-end is used to handle all Cosmos' IT infrastructure, and is being continuously improved on to this day.
