Haasboy Software was the name of a website maintained by Ryan de Haast, brainchild of Rising Evil and Double Trouble. De Haast would also use the name as an author name, though Haasboy Software only consisted of one person.

De Haast formerly hosted the Wolfenstein Cabin, and moved to Haasboy Software later on; the site was relaunched numerous times, lastly in connection with a mod called F.A.D.E.D., though De Haast drifted away from the modding scene shortly after.

There is no working link to Haasboy Software.
