The web interface was artistically designed by Thomas Blume using
YAML. It was technically implemented by Dirk Hünniger using the Blaze Html Framework in Haskell. Important ideas on the design of the user interface were contributed by Georges Khaznadar and Martin Wermers. The server this interface is running on is run by a WMF, who have to cover the costs, so
please consider downloading the full version for free and running at on your own hardware instead of using this server.
